Frank Stührenberg, CEO Phoenix Contact E D I T O R I A L Networked and connected Dear readers, According to a United Nations forecast, more than 54 percent of the world’s population will live in cities by as early as 2030. Urbanization is a global megatrend. And also a task for Phoenix Contact. How do we use technical solutions to achieve the energy revolution to make the city a more livable and sustainable place for everyone? In this issue, we will show you an example of how we are approaching the huge fi eld of infrastructure. We begin this straight away with the lead story, Smart City, in which we have “walked through” exciting topics with experts. Technology and creativity make life in the city more livable. And just a few kilometers away, everything revolves around the most important sideline activity in the world – soccer. In Bielefeld, the SchücoArena is a highly vibrant part of the city’s culture. We do not control the ball, but behind the scenes we control the technology of the stadium. Whether as a partner of a large housing company that makes heating affordable for its tenants with smart solutions, or with the tiny houses made by the Scheidt company; whether with the bidirectional charging of electric vehicles, or with the ski jumpers in Oberstdorf – connecting energy and networking data – this is how new solutions are created that refl ect our vision of the All Electric Society. And they show that modern technology can be the key to mastering the challenges of the future. The Phoenix Contact innovation magazine UPDATE 1/22 3

F R O M T H E I N D U S T RY Heat storage Solution from the test tube 55 percent of the energy required in Germany is used for heating or cooling. The problem here is that natural heat is usually generated at inappropriate times. In winter it is cold, and heating energy is needed. On the other hand, there is plenty of energy in summer, but it is incredibly diffi cult to store it long-term. One way to store energy is via chemical reaction. This is not a new process – after all, the principle of pocket warmers is well known. They contain a saturated solution with sodium thiosulfate. If the warmer is mechanically fl exed, heat is generated via crystallization. However, this property has so far proven to be unsuitable for large-scale applications. At the Institute for Process Engineering, Environmental Engineering, and Technical Biosciences at the Vienna University of Technology, the principle is being implemented with other substances. Here, boric acid is mixed with oil. In a reactor, waste heat is used to generate a temperature of 70 to 200 degrees. In this process, the boric acid separates off water and boron trioxide is formed. The water escapes; the boron trioxide remains in the oil. This solution is stable and long-lasting. If water is then added again, boric acid is reformed. And this reaction generates heat, which can be used for heating applications. Further research is being carried out to study how often this process can be repeated and how high the effi ciency is. tuwien.at Building automation Utility vehicles A robot for bricks and mortar Size does matter The Swabian Liebherr Group and the Australian company FBR Ltd are planning to take Europe’s construction sites by storm with a brickwork robot. “Hadrian”, as the digital construction worker has been named, has already constructed its fi rst buildings in Australia. The mobile robot can handle all the masonry work for an entire building outdoors. Quickly and precisely. And of course, without taking a breakfast break or working at overtime rates. Liebherr Mischtechnik and FBR have agreed to further develop the successful prototype for the European market to bring it up to series- production readiness. liebherr.com It is big. And heavy. And green. However, the battery-powered electric monster is not called Godzilla, but Lynx. And instead of wreaking havoc in major Japanese cities, the world’s most powerful e-vehicle has recently been working in the Swiss town of Péry in the Bernese Jura. A few key fi gures for the giant: Empty weight – 58 metric tons. Loaded weight – 123 metric tons. Battery block weight – 4.5 metric tons. Capacity – 600 KW/h. Torque – 9,500 Nm. When the gigantic dumper truck, fully loaded with lime and marlstone from the quarry, drives downhill, the synchronous motor produces enough electricity to power the subsequent uphill journey. The e-Dumper is expected to transport 300,000 metric tons of material per year. If the project – a collaboration between numerous companies and, among others, the Bern University of Applied Sciences BFH – is successful, it will save around 500,000 liters of diesel and 1,300 tons of carbons dioxide. emining.ch The green giant of mining The Phoenix Contact innovation magazine UPDATE 1/22 7

S M A RT C I T Y The smart little town What makes cities smart and communities clever? We went in search of clues throughout the neighborhood. And not only found a model city with charm and character, but also extremely accomplished interlocutors. A walk through Lemgo … 9

Bluetooth and Wi-Fi scanners for detecting smart devices WLAN access points Noise level sensor Network distributor box – network and power supply Stalwart university lecturer Lemgo, with a total of 40,000 inhabitants, is far from being a metropolis. Even though the small town in East Westphalia-Lippe has plenty of picturesque half-timbered buildings, a castle, and plenty of countryside around it to offer. Professor Dr. Jürgen Jasperneite explains to us why it is nevertheless ideally suited as a blueprint for the development of Smart City applications. We have an appointment with the director of the Fraunhofer IOSB- INA , the institute branch for industrial automation in Lemgo, and professor at the OWL University of Applied Sciences, for a walk through the old Hanseatic city: “We have a microcosm here that has all the same things that characterize big cities. Therefore, we can easily scale the applications we develop here. And we benefi t from a lean and open administration.” We are accompanied by Jörg Nolte, Vice President VMM Infrastructure and thus the person responsible for smart cities at Phoenix Contact: “This subject has been developing rapidly in recent years. We are now active in projects and ventures throughout the world.” City with sensors No sooner have we walked the fi rst few meters than we come to a halt again. Professor Jasperneite points upwards. “Here, we have installed a sensor box with traffi c counting and noise level measurement capabilities. We have installed around 30 of these systems in the Lemgo area.” The digitalization of the infrastructure in Lemgo began in a completely different place. More than 100 sensors were installed in the district heating network of the municipal utility. They now ensure transparency and effi ciency for this type of heating supply. Jasperneite explains. “You have to measure, control, and regulate something. Then you have to transfer the measured values. This is increasingly being performed wirelessly, either via cellular communication or with special networks such as LoRaWAN. And then we have the data platform, in which the data is recorded and evaluated. And overarching all of this is the actual application. This pattern is practically the same for all applications.”  The Smart City Box evaluates movement, balances parking spaces, and can be used for demand-driven circuits Solar panel for the power supply KNX wireless motion detector 11

High-resolution cameras enable classifi cation by type Vehicle types are detected and evaluated automatically These cameras only detect motion Data is transferred wirelessly, thus ensuring easy installation “The Smart City Box is the link between digitalization and the real world.” Jörg Nolte Emergency services have priority Another project is a priority circuit for emergency vehicles. New vehicles have an onboard unit that knows where the vehicle is at all times based on GPS measurement points. The professor points to the traffi c light mast. “The small black spheres are cameras that can detect whether traffi c is fl owing or not, similar to a motion detector. However, to recognize an ambulance, for example, we need a high-resolution video scene on which we can detect movement, long lines, and vehicle types. We therefore installed additional cameras.” Jörg Nolte continues. “With the Smart City Box and connected video sensors, we can perform this object detection in road traffi c. The detected images are surrounded by different digital frames. Thus, the computer can distinguish with very high probability between cars and trucks and can identify pedestrians and cyclists as such.” Jürgen Jasperneite explains further. “Now, if an ambulance with blue lights comes within 500 meters of the traffi c lights and passes the reporting point, the onboard unit sends signals. These are recorded and processed here and transmitted to the traffi c lights so that the controller is switched to red. Ideally, any backlog that may have formed at the traffi c lights will also be relieved before the ambulance arrives so that the emergency vehicle can pass through without any problems. The trigger is therefore positioned in the vehicle and actively initiates the process of local priority switching.” Sighing a little, he adds, “As is often the case with Smart City topics, what initially appears to be a simple process becomes  The Phoenix Contact innovation magazine UPDATE 1/22 13

S M A RT C I T Y this information made it possible to take measures to regulate the number of visitors and to record and publish the waiting times in front of the test centers set up in the Lippe district. This fl owed (and still fl ows) directly into the data platform and is available to citizens in real time. With sure steps, Professor Jasperneite guides us after a few hundred meters of walking to the heavy oak doors of St. Mary’s church. The parish church is one of fi ve inner-city churches in Lemgo. But what does a house of worship built around 1260 have to do with Smart Cities? We are welcomed by the cool atmosphere of the imposing nave. Again, our professor points upward. This time, however, to a special exhibit. “This here is a very rare Swallow’s-Nest organ from the Renaissance, so a good 400 years old.” “We use humidity sensors to monitor the air situation around this wooden treasure,” explains the knowledgeable Jasperneite. “This data is also fed into our data structure via the cloud. The request actually came from the sexton himself,” says Jasperneite, pleased with the unexpected and unusual application. “You do not fi nd this level of creativity very often. Digitalization is supposed to simplify everyday life. But often, decisionmakers lack imagination about what is possible.” Any weather The probability of turbulent climate events is increasing. In Lemgo, the Bega River fl ows through the city area. Normally a small river, this watercourse developed into a raging torrent during the recent record rainfalls. And stone bridges and weirs dammed up the water masses – the city center was in danger of being fl ooded several times. The administration has already reacted and re-naturalized the course of the river, dismantled weirs, and established fl ood plains. But the potential Smart City connection is still missing. This would be easy to implement, as Jürgen Jasperneite explains. “We have applications for this in a neighboring community. Again, it would be possible to link a fl ood warning system with parking and traffi c control systems intelligently.”  Flood scenarios can also be detected The Phoenix Contact innovation magazine UPDATE 1/22 15

S M A RT C I T Y The link to reality The Smart City Box is much more than just a control box with inner workings. The Bad Pyrmont location is home to the masterminds, experts, and engineers who are working on solutions surrounding the Smart City. Christoph Hülsmann is one of them. He explains what is special about the box. “First and foremost, it is the universality. In fact, all other providers have their own solutions ready for their specifi c applications – whether for water treatment plants, traffi c planners, weather, or warning systems. The problem, as is so often the case, is the ability to link the data silos together. It would be possible to create truly smart applications if these silos were evaluated and then merged into an overall data structure. And that is exactly what our box is able to do.” The 46-year-old Solution Engineer points to a test system on his own desk. A video camera is connected to a Smart City Box. On the monitor that reads out the data from the box, you can see vehicles that are detected in different grids. “We have recently been working intensively on intelligent lighting control for cities and are now installing these solutions throughout the world. Another major topic is traffi c monitoring – Traffi c Detection. Here, we do not just determine where something is. But we also need to reliably detect exactly what it is. To do that, we use artifi cial intelligence, which we program into our controller.” The expert emphasizes that this type of recording and recognition is not about creating personal profi les, as critics often complain. “We are not interested in license plates or faces. The entire technology is aimed at contextual data. Naturally, we need information so “Our Smart City Box can analyze data from a wide range of applications. That makes it unique.” Christoph Hülsmann readies the Smart City Box fi t for numerous application areas that the connected systems can react. But individualizing the data does not play a role at all. It is important that information is available at the right time so that automated processes can be triggered.” Hülsmann strokes ‘his’ Smart City Box. “At the heart of it, of course, is our PLCnext Technology, which is superbly modular and we can adapt it to almost anything. And due to our further developments, we have enormous communication capabilities, whether via WLAN, wireless, or fi berglass. The box is truly a gateway for Smart Cities.” Christoph Hülsmann has just one criticism. “We will make it much smaller. Then it will be even better.” (lo)  Always hungry – the Smart City Box guzzles everything that sensors can deliver in terms of data The Phoenix Contact innovation magazine UPDATE 1/22 17

And in terms of the stadium, we can be champions.” The stadium boss believes he is well positioned to meet this challenge. He is assisted by two long- standing experts, Maik Lohmeyer for IT and Daniel Müller for facility management and technical management. You could say a triumvirate in terms of stadium renovation. The trio is supported through cooperation with Phoenix Contact. “We thrive on the emotions of the stadium. Around 20,000 spectators, fl oodlights, a great atmosphere – that is our lifeblood. We can manage these things, we have them under control. But not the technological side of things. In this respect, we need strong partners. And that includes Phoenix Contact in particular.” The heart of Bielefeld But what signifi cance does an inner-city stadium have beyond the popular sport of soccer, especially since its turf is reserved just for the small band of professional soccer players and the rest of the facility is only occupied every 14 days for home games? Venghaus disagrees. “We are the emotional engine of the city and the region. Of course, we are struggling with the logistical disadvantages, especially with regard to the arrival and departure situation and the shortage of parking spaces. But people love the proximity to the city and they can come by bike, public transport, or even on foot and have a post-match drink in one of the bars in the area right after the game. There are only a few comparable stadiums left in the professional leagues, including Bochum, St. Pauli, Kaiserslautern, and Munich 1860 – these are unique selling points that these clubs benefi t from.” IT manager Maik Lohmeyer adds, “We are not a multi-functional arena with major events beyond matchday operations. The offi ce has 60 employees who are active on site every day. In addition, there is space that is rented out as normal. We also have projects such as the Stadium School, where students come to us for classes three days a week. Workshops and conferences are also held here. So there is a lot going on in the SchücoArena during the week as well. However, there are no evening events such as parties or weddings.” Old treasure Daniel Müller has been with Arminia for 22 years and knows the Bielefeld venue like the back of his hand. “Our stadium dates to 1996, in parts to 1999,  The Phoenix Contact innovation magazine UPDATE 1/22 21

(lo)  arminia.de Tablet instead of a control center – how the staff keep an overview Greinert explains. “We are connecting the state- of-the-art controllers in the new control cabinets to the building management system. Not only the ventilation systems but also the consumption meters are already managed via this system. This means that Arminia staff such as Daniel Müller can access this data from anywhere via tablet or laptop and make interventions wherever necessary. We receive messages on our cellphones and then take action; it operates via an alert management system.” So the term ‘home offi ce’, which makes Lohmeyer and Müller smile, it not quite right. “On weekends, we are almost always all in action, especially at home games. And then there is the occasional seven-day week. Four or fi ve people have access to the technology and can then also take action as needed. When the experts at Arminia Bielefeld talk about controllers, however, they are not just referring to meter readings or visitor fl ows, as Maik Lohmeyer explains in the locker room tunnel. “In this tunnel, which leads from the locker rooms to the pitch, light and sound are adapted to the respective team.

D ortmund Gartenstatt, in the middle of the Ruhrpott region. A region that used to be associated with steel and coal and now is associated with structural change and the dawn of modernity. It is precisely this fi eld of transition that we are on the trail of, even though today’s topic is technology and not mining romance. A few steps and a steel door; then we are standing in the boiler room of a multi-occupancy house. The bulky oil burner burbles away happily. The system, which was installed in 2016, produces a maximum of 320 kW for the heating and hot water supply of 48 residential units that cover a total area of 5,307 square meters. “In addition, there are the same number of two-and-a-half to three-and-a-half-room apartments in the neighboring building,” Wilhelm Risse adds. Willi, as he is known here, is a trained electrician and has been with Vivawest for 21 years. He knows this and several other systems like the back of his hand, because he is one of the service technicians of the Gelsenkirchen housing company. Installation and maintenance in particular are key issues in Risse’s everyday life. And this is because “the heating system has to work, there cannot be any malfunctions.” However, due to the still high proportion of oil and gas heating systems in our neighborhoods, this is a task for the coming decades. It is therefore worthwhile to make these heating systems more effi cient as well,” says Manuel Romberg. He is a site manager at Vivawest and responsible for digitalization. “We have been looking for ways to make the inherently analog older-style oil and gas heating systems more energy effi cient. That is to say, making a brainless heater smarter. And we came up with the idea of using the signal generator of the outdoor temperature sensor for this purpose.” This sensor usually measures the outside temperature to control the heating system and turn it down in summer conditions and turn it up accordingly in winter. “We developed our own controller that acts on the heating system through this channel. We combine the data from multiple outdoor sensors to obtain a centralized reference. This allows us to adapt the systems to the actual temperatures.” Not without pride, Manuel Romberg points to the control box in which the controller with the Vivawest logo has been installed on the DIN rail. “We have also already patented this heating system controller.” Cold feet versus climate change But Vivawest is not just a housing company; it also has its own engineering departments in various trades. “In addition to equipping our new construction projects with renewable power supplies, we are beginning to replace fossil fuels such as oil and gas in our portfolios with a combination of air-source heat pumps and photovoltaic systems over the long term. Making brainless heaters smart Although the electrical engineering graduate was already aware of Phoenix Contact, contact was intensifi ed during a project in which the level monitoring of the tank systems was digitalized. “Back then, Phoenix Contact not only supplied us with components and advised us, but also worked together with our technicians to fi nd solutions to problems in the  A heat output of 320 kW is produced here.

U R B A N D E V E LO P M E N T system. This means that old systems can be supplemented with modern control techniques, such as weather forecasts, and thus save energy immediately after the technology is installed. In the fi rst fi eld test with 400 heating systems, the central controller of the heating systems achieved energy savings of around 12 percent. To put things into perspective, Vivawest is one of the leading housing companies in North Rhine-Westphalia and manages almost 120,000 apartments in around 100 communities in the Rhine and Ruhr region, providing homes for around 300,000 people. And so the 12-percent carbon dioxide reduction quickly reaches industrial dimensions. Climate-neutral home Manuel Romberg places the developments in a broader context. “By 2045, the building stock in Germany should be climate- neutral – that is to say, no more carbon emissions. To meet this federal government goal, our new buildings already have to be energy effi cient. And in existing buildings, further steps are needed in terms of energy modernization to contribute to an increase in effi ciency and a reduction of the overall energy demand. This will involve digital building management (DBM) taking on a key role in reducing energy consumption and also operating costs for our tenants along with it. Due to the positive experience from the fi rst fi eld test, 300 additional heating systems have now been equipped with the IoT controller from Phoenix Contact. This was preceded by a joint advancement of the management platform for the control and automated optimization of the plants, so that the Vivawest employees in charge can use it much more conveniently and on their own for whatever purposes they require. The aim is also to advance the automation of operations management and develop further applications. Heat is the key As the Director of Global Industry Management, Bernhard Tillmanns manages the Building Technology unit at Phoenix Contact. The experienced automation expert outlines the prospects for the housing industry. “Supplying heat accounts for 70 to 80 percent of energy requirements in buildings. When we talk about the energy revolution in buildings, the heat is thus at the forefront. Therefore, the automation concept in neighborhood development must be heat-focused, not electricity-focused.” However, further steps are needed to achieve the ambitious goals of climate neutrality. “Without sector coupling, it will not be possible to achieve the climate targets in the building sector,” Tillmanns says with certainty. “Therefore, automation processes must also extend to power generation and consumption. Photovoltaics and heat pumps will be integral parts of buildings in the future. Energy storage is needed to put the electricity generated to good use. The systems for heat generation require electricity, and we also have to integrate the infrastructure for e-mobility into the buildings, for example in the underground parking lots of apartment buildings. So the grid connection technology also is part of the overall concept. That is why we at Phoenix Contact think beyond the individual building. Because a building can also be automated to serve the grid by integrating negative control energy. For example, if there is too much renewable electricity in the grid, storage facilities can be charged or some heating and cooling processes can be regulated to cushion the excess supply. Such an approach is of course also an option in the context of the energy optimization of a neighborhood. That is why, for us, a neighborhood solution always includes networking the buildings.” Tillmanns is certain that precisely the right tools are available for this. “The Emalytics management platform used here can do more than just connect, automate, and optimize existing conventional central heating systems. The IoT-based management system also integrates regenerative energy generators such as photovoltaics and heat pumps as well as e-mobility charging infrastructures into holistic operating systems, regardless of the manufacturer. In this way, Vivawest is prepared to actively shape the energy revolution through its properties.” “And this will ensure that our tenants do not get cold feet in the future,“ says Wilhelm ‘Willi’ Risse happily.

Harmonizing social and environmental responsibility with economic goals – we want to master this triad. This is due to our entrepreneurial DNA, which we were born with as a company based in the Ruhr region on the site of the old Nordstern colliery and with shareholders such as the Industrial Mining, Chemical, and Energy (IG Bergbau, Chemie, Energie – IG BCE) trade union. When we redevelop entire residential neighborhoods, we take a holistic approach that focuses on social balance as well as housing aspects.  Data collection and networking are central to automation. How high is the acceptance level among your tenants? Very high. Because each individual tenant benefi ts from it. Our goal is to ensure that a problem with a heating system, for example, is detected before it goes cold and tenants call in. The fi tter should already be on their way with the right replacement part. Predictive maintenance is still uncharted territory in the residential industry. However, to ensure data security, we have already developed our own security standards and host our data on our own servers. And our tenants justifi ably rely on this. (lo)  vivawest.de

Scheidt specializes in precast concrete elements I f there is one company that knows a thing or two about secondary substations, it is the Scheidt family business in Rinteln on the Weser River. The Lower Saxons not only have a practiced and skillful hand when it comes to the shell of the concrete building, which is the basis of safe architecture within the power grids. They are also experts when it comes to equipping the electric bungalows, which weigh tons, with their electrical and electronic inner workings. the company premises On-site meeting in Rinteln Anyone visiting in Galgenfeld on the outskirts of the small town in Lower Saxony will involuntarily duck their head in light of the heavy loads that fl oat through the space. Helmets are mandatory when walking around the expansive outdoor area. At Scheidt, concrete is not only formed, but also learns to fl y. At least over short distances. We meet Carsten Hohmann in front of the four-and-a-half-meter-long, one- and-a-half-story building, which is Scheidt’s latest fl agship, wearing an appropriately discreet helmet. The Rinteln-based company has developed an ingenious grid system that allows it to adapt its tiny houses precisely to site requirements, even in the shell stage. Turnkey transformer stations are the domain of the company, which was founded way back in 1889. While at the beginning of the company’s history the focus was on quite normal construction projects, the production of precast concrete elements became more and more important, particularly from the 1950s onwards. Even prefabricated garages were in the portfolio for a while. Scheidt’s fi rst transformer stations were actually identical in construction to the proven motor vehicle housing. It depends on what you make out of it. Scheidt has an innovative relationship with concrete as a building material: For years, special spun concrete was used to produce electricity pylons in Rinteln. Charged In the meantime, however, the three locations of the medium-sized company (Rinteln in Lower Saxony, Hoyerswerda in Saxony, and Arnstadt in Thuringia) have concentrated on transformer stations in general and secondary distribution stations in particular. Carsten Hohmann points to a whole row of concrete shells that are largely bare, because they have not yet been equipped. “Today, we are one of the most important manufacturers of transformer stations in Germany.” inside the mostly So the shell has been explained, but what is actually inconspicuous buildings? The Plant Design Engineer explains. “Such a transformer station initially houses one or more transformers. These transformers regulate the current from its transport voltage of the medium-voltage grid down to a consumer- friendly 380 volts in the low-voltage grid. This is necessary because for electricity to fl ow at all over long distances, the voltage must be at least 10,000 volts.” And against the backdrop of the energy revolution with its decentral solar and wind generators, the electricity generated also has be transformed back up, ‘ready for travel’. This calls for a new grid architecture with numerous points where electricity must be adapted to the grids. It is no wonder that Scheidt sees itself as future- oriented. In the meantime, and far beyond the country’s borders, both in England and in the EU environment. The Phoenix Contact innovation magazine UPDATE 1/22  31

The medium voltage is regulated down to low voltage here “We offer turnkey stations, including electrical engineering equipment for all grid levels.” Carsten Hohmann, Plant Design Engineer use quite a few standard parts, but still be extremely fl exible in meeting the customer’s requirements. Not only with the outer shell, but also the inner workings. This is what sets Scheidt apart.” After we have left the walk-in transformer station, the chains of the lifting crane tighten. And in no time at all one of the pioneers of the energy revolution is gently fl oating onto the fl atbed of a low-loader to make its way to its new location. Inconspicuous, angular, yet full of inner workings that make its use future-proof and indispensable for decades to come.

This visually appealing home charger from Evtec is called sospeso&charge These fl uctuations have to be kept in check by energy storage systems. They store yields when the sun shines and the wind blows. And they feed into the grid when there is a lull or darkness. The problem is, these systems are large, very expensive, and far from available in suffi cient numbers. Storage during downtimes Against this background, it becomes understandable why an armada of mostly stationary but mobile energy storage devices such as the batteries of e-vehicles, gets attention. But how do you tap into this untapped treasure trove of energy? One company that has been dedicated to this topic for a long time is based in Kriens, Switzerland. Evtec has been developing and manufacturing charging technology for more than 12 years. Evtec was founded by Marco Piffaretti and others in 2010. The bearer of this illustrious name is one of Switzerland’s electric vehicle pioneers and a trained car designer. The small startup has long since become a recognized player, with manufacturing sites in Poland and subsidiaries in various European countries. Dominik Mock opens the doors to the Swiss headquarters. In Kriens, about 40 employees think, assemble, and monitor Evtec technology. Dominik Mock is head of sales and, as a trained electrician, also a man of the trade. Together with Swiss Phoenix Contact colleague Stefan Staiber, we are on the trail of a very special home charger. Whereas DC charging was previously thought of as the lightning-fast charging of large batteries, for example on freeways, today it is intended to be somewhat more leisurely. This special home charger was developed with applications at work or at home in mind. Charging is still with direct current, so comparatively quickly. But with a charging power of 10 kW, the charging times cannot be compared with those at classic fast-charging stations. The home charger is installed by means of a three-phase supply line with 16-amp fuse protection. In other words, the installation is comparable to a normal stove connection and does not require extensive work on the household electrical system. For communication, an energy meter is required, which  The Phoenix Contact innovation magazine UPDATE 1/22 35 power stations providing the power, do not actually like fl uctuations. For decades, the giant power generators have been constantly humming along, always feeding electricity into the grids at a steady rate. And without fl uctuations. But since renewable energies have begun their triumphant advance, the steady world of electricity suppliers has been severely stressed. Solar power stations only supply when the sun shines. And wind power is only fed in when the wind blows. In addition, there are now loads that no one had on their radar 20 years ago. The rapidly increasing electrifi cation of mobility is calling for large amounts of energy for which the distribution grids are not designed.

C H A R G I N G I N F R A S T R U C T U R E Another obstacle is the price, as the 36-year- old Head of Sales at Evtec openly admits. “With a purchase price of well over €10,000, only a few private individuals will be willing to invest in this technology right now.” But the expert is sure that economies of scale will quickly come into play here, making the technology more attractive. “And this is precisely why Phoenix Contact is the ideal partner,” Mock elaborates in a conversation with his Swiss contact Stefan Staiber. “You guys have developed just the right technology to make DC charging attractive in this area. Slim and thus lightweight cables that are extremely resilient and durable and do not require complex and thus expensive cooling in this load range. And a connector that is anything but clunky, despite the CCS mating face.” “Bidirectional charging is one of the most exciting fi elds in charging technology.” Stefan Staiber, himself a veteran of the Wave Trophy and thus also familiar in all aspects of electric vehicles, adds, “The CCS-C-Line charging cables and connectors used by Evtec have been specially developed for home chargers. Although the large HPC charging connectors including cable are ideal when it comes to heavy use at public charging points, in the private sphere, we would be shooting at sparrows with cannons. CCS C-Line fi lls exactly this gap with the right choice of materials, the right robustness, and a design that does not resemble a service station. Silver-plated contacts, an internal sealing concept, and highly sensitive temperature sensors are safety features that make handling safe and easy for both the European CCS type 2 standard and the primarily American CCS type 1 standard.” During a tour of the production facility in Kriens, Dominik Mock explains. “Behind each of our developments is a specifi c order. We can respond very individually to customer requirements, such as DC-DC charging stations or the integration of payment terminals, and we have even developed the integration of coffee vending machines. For us, the topic of charging is a huge playing fi eld. And bidirectional charging is one of the most exciting topics out there.” (lo)  Dominik Mock, Evtec evtec.ch/en Evtec relies in-house on discarded battery units from the Nissan Leaf 37

T R A N S P O RT R O U T E S Completion on site After a great deal of preparatory work and various electronic meetings, the fi nal tasks on site were fi nally on the agenda. “I already knew the on-site technology in detail, but the actual visuals are something totally different. When we drove out of the fi rst tunnel and there was this beautiful landscape stretching before us, it was breathtaking. It was warm and the haze hung on the mountains and over the trees.” The Phoenix Contact and Schréder team was made up of six people and very international: one Chilean, two Brazilians, two Belgians, and Michael Rolf as the representative German. “The face-to-face contact on site just does not compare to emails and meetings via Teams. It is crucial to get a picture of the situation directly with colleagues, to exchange ideas, and then to know exactly which framework conditions may still have an infl uence on installation, commissioning, and later the regular operation. I also need that moment when I go out and see my code controlling entire tunnel systems. That is always fascinating,” says Michael Rolf. “You have to remember that the people who use the tunnels later on have complete trust in our technology. Therefore, it must function fl awlessly.” (lo)  For further impressions, go to: update.phoenixcontact.com effect. This means that we dim the lighting in accordance with the current lighting conditions so that the eyes can get used to the darker environment in the tunnel. If the contrast were too great, you would only see black, and then accidents can quickly occur,” explains Michael Rolf. In the best-case scenario, motorists will not even consciously notice how we adjust the brightness in different areas of the tunnel.” The main goal was to be able to operate the LED lights from the Belgian manufacturer and specialist for LED lights, Schréder, as effi ciently as possible, to save energy and to still have a high availability as well the ability to monitor the individual LED lights. If the lighting is to be strongly dimmed – at night, for example – the control system switches off some of the lights while dimming those that remain. This extends the service life of the LED lights, optimizes the power factor, and reduces reactive power. In addition, even factors such as cleaning, maintenance, and age-related losses are taken into account. For this purpose, Schréder has integrated the Lumgate activation electronics from Phoenix Contact directly into the lights or the associated driver boxes. This allows the current in each individual light to be measured and monitored. The parameters for the individual LED lights can be defi ned individually for each light point. 50 predefi ned scenarios provide optimal control, and can even respond to spontaneous events through higher priority events, such as an accident in the tunnel. The system is designed in such a way that even without connection to the tunnel control system, the lighting functions faultlessly. Even if the entire network fails, the various systems continue to operate independently. If additional ventilation or drainage is also to be integrated into the automation, this can be done without great effort or complex adjustments. The Rodovia dos Tamoios was known to be very accident-prone; hence the complete reconstruction Jungle all around, and a sober high-tech atmosphere in the tunnel 41

C O M P E T I T I V E S P O RT S On approach Oberstdorf is actually a small town like so many throughout the Alps: picturesquely situated, perfectly developed for tourism, and, particularly in winter, overrun by skiing enthusiasts. The fact that the name nevertheless has a unique ring is due to two monumental structures and its daredevil users. 143.5 meters – the record set by Sidurd Pettersen on the large hill in 2003, which still stands today 5 ski jumps make up the Audi Arena Oberstdorf. The ski-fl ying hill is a separate facility 43

C O M P E T I T I V E S P O RT S holds a doctorate, and his team from the Institute for Applied Training Science (IAT) supervise the German ski jumpers and Nordic combined athletes. We are at the Audi Arena. Instead of snow mountains, fi ne Sahara dust covers the area. Even on the large and normal ramps, where we meet Dr. Müller, just a few remnants of white splendor are still fi ghting against the spring sun. There is still an almost dead silence here, while a few kilometers away hectic activity has broken out. The elite ski fl yers are meeting at the Heini Klopfer ski-fl ying hill. But here, on the eastern outskirts of Oberstdorf, only the IAT team is busy checking their permanently installed analysis system. “We will go to the ski-fl ying hill later and set up the mobile system,” says Dr. Müller, setting the time frame. Panoramic view Fixed technology has been installed on the large hill, so the mobile unit remains in its case. Right next to it is the normal hill, which is complemented by three children’s and youth hills. When the jumpers on the ski jump thread their skis into the icy jump tracks, they have an impressive view of Oberstdorf. Or a scary one, depending on your disposition. “The jumpers only see the hill down to the jump-off platform. They cannot see anything that comes after that,” says Dr. Müller, describing the perspective typical of ski jumpers. You have to be a little crazy to dare to do that, right? Müller grins, “Well, not when you grow up with it.” Ski jumping is a strange sport. There are only about 1,000 people in Germany who are involved in it, whether as active players, trainers, or supervisors. And it is a purely serious and competitive sport. The fun usually comes to an end when a jumper reaches the age of 20, because that is when they reach peak performance. And ski jumping is not suitable as an amateur sport. “Nobody does that. Once you stop, you never jump again.” Jump into the blue The length of a jump is measured from the edge of the jump- off platform to the point of landing. In Oberstdorf, the take-off speed is around 90 km/h on the large hill, and the jumpers remain in the air for around fi ve seconds. Apart from the structure of the hill, the athlete’s body and skiing posture play a crucial role. If the mixture of wind, lift, and air resistance is right, then impressive distances are possible. This is where the technical challenge begins, supporting coaches and athletes with video recordings and objective data in such a way that it is possible to optimize the jumping performance. This support is necessary because the ski jumper themself does not see their body position, and the trainer is only standing at one point next to the hill and thus does not get a comprehensive picture of the entire fl ight duration. For optimization, video recordings of all phases of the jump are desirable in the best case. Therefore, eight and eleven cameras respectively were installed on the jumps in Oberstdorf at fl ight path height at close distances to each other. The cameras must be mounted parallel to the jumper. Dr. Sören Müller has been at the IAT for years and is head of the ski jumping/Nordic combination section in the Power Technology department. Founded in 1992, the scientifi c institute, with its headquarters in Leipzig, functions as the central research unit for German top-level and junior  Speed is crucial for the signaling. Otherwise, the camera will miss the jumper The jump is evaluated with AI and transmitted to the trainer after a few moments The Phoenix Contact innovation magazine UPDATE 1/22 45

Ski jumping is a purely competitive sport that pushes the limits of physics A sequence is generated from the individual images, which allows conclusions to be drawn about the jumper’s technique “Neither the athlete nor the coach have these perspectives during training.” Dr. Sören Müller on the importance of jump shots for a very short time. The camera must therefore be triggered immediately so that it is possible to edit the video sequences together in a meaningful way afterwards. And beyond that, weather resistance is of signifi cant importance. The control system must therefore comply with protection class IP68 and be resistant to cold. The control system and all other components should function reliably even at a temperature of -20 degrees Celsius. Ski sports with control Based on the framework conditions described, those responsible decided upon a PLCnext Control system. In addition to the fast cycle time, it was the extended temperature range of -25 degrees Celsius to 60 degrees Celsius that convinced the decision makers. To the right of the controller in the control box, you can see an Axioline F module with 16 digital inputs that are used to record the data forwarded by the cameras and in turn to forward it to the controller. The individual components are wired using the tool-free Push-in connection technology. The sports scientists have also developed an AI system together with the University of Augsburg. This makes it possible to automate the fl ight analysis so that the decisive angles of body and ski to the fl ight path can be determined and displayed very quickly. These analyses allow coaches and athletes to take a close look at their technique and fi ne- tune the details that make the difference between victory and defeat. Enough of words and explanations – things are getting serious. For the scientist. After all, the ski-fl ying competition is about to start on the Heini Klopfer ski-fl ying hill. And there, Dr. Müller, his staff, and his mobile measurement and analysis solution, which is indeed housed in a heated suitcase, are already eagerly awaited. Dr. Sören Müller grabs the case, smiles at our enthusiasm for the backdrop and contact, and signals: From now on, the athletes’ schedule sets the pace again.

B E H I N D T H E S C E N E S Sunny showcase Solar park in a park Where Lower Saxony and North Rhine-Westphalia meet, it is not just the middle of nowhere. Soon, a solar showcase project between Himmighausen and Oeynhausen will also provide further energy independence. Land is a rare commodity. Even in the countryside, farmers compete with commercial estates, construction sites with landscape conservation areas, and solar installations with nature conservation areas. And so it was not at all easy to succeed in gaining approval for a planned 16-hectare solar park. But the owner of the land, Georg von Puttkamer, was not discouraged by the initial headwind and changed the original plans several times. In the meantime, based on the improved proposals, the responsible authorities have given the green light for the ‘Nieheim Solar Park’. The term ‘park’ is to be taken literally, because meadow orchards, hedges´, and copses are intended to take away the industrial character of energy production. Sheep are to keep superfl uous greenery short; bee meadows and nature trails will invite visitors to linger. A total of 30,000 modules will stretch across the site and are expected to generate up to 11.2 megawatts of power. Enough energy to supply about 3,200 households with electricity all year round. The park is being built by the project company BLG from Kassel in northern Hesse. And BLG is one of Phoenix Contact’s system partners. The East Westphalians do Georg von Puttkamer, Christian Hess from BLG, and Jörg Nolte (from left to right) not just supply connection technology and sensor technology, but also the central feed-in controllers that regulate and monitor the power transmission into the power grid. Jörg Nolte, Vice President VMM Infrastructure, is not only convinced by the project because it can be a role model for other solar parks due to its citizen participation. “The park is scheduled to open in 2023. And thus exactly fi tting for our 100th anniversary of Phoenix Contact. With this, we will have a real innovation, both technologically and in terms of landscaping and sustainability, right on our doorstep,” the top manager is pleased to say. blg.eu The marathon award 15 years of cooperation with Siemens The company history of Phoenix Contact is closely intertwined with the Siemens Group. Now, a new chapter in this special relationship of trust has been recognized with an award. More than 100 colleagues from different areas of Phoenix Contact work together on the development, production, and delivery of electromechanical components for Siemens. The beginnings of this cooperation date back to 2005. “We supply the connection technology and essential housing components of the base unit for Siemens’ main automation line,” explains Andreas von der Kall, head of Global Key Account Management for Siemens. “In cooperation with Siemens, we set up parallel production in Germany and China for this purpose.” The cross-divisional team received the ‘Siemens Supplier Award’ for this achievement. The optics are also electrifying Excellent grip for fast energy Following the multiple award-winning AC charging cables, the product fami- ly for DC charging cables for the lower power range – the ‘CCS C-Line’ – has been awarded the Good Design Award 2021. And this is no small achieve- ment: The award from the Chicago Athenaeum Museum of Architecture and Design has been presented for outstanding industrial and product design annually since 1950. The jury of experts emphasized the convenient handling and modern appearance of the charging connector for private as well as public and commercial use. Together with designer Stephan Gahlow from Hamburg, Phoenix Contact focused on an ergonomic and stylish design with simple operation during development. And, naturally, the respective functions: The DC charging cables enable fast charging with direct current in the lower power range for the fi rst time. They are designed for modern DC home charging stations in garages and carports and for small DC charging stations in the commercial sector. good-designawards.com The Phoenix Contact innovation magazine UPDATE 1/22 49
