CHARX manage – charging and load management for charging stations and charging parks

Charging and load management for charging stations and charging parks

Manage your charging infrastructure with CHARX manage. The scalable software optimizes the operation of your charging stations, increasing their availability and enabling precise billing of charging via the Open Charge Point Protocol (OCPP). The rule-based load management system distributes the available connected load to all charge points so that electric cars are charged with electricity based on need and the building connection operates at optimum capacity and is protected against overload.

With the growing number of electric vehicles, the demand for charging options is increasing. Parking lots and parking garages are therefore increasingly being equipped with charging stations. The planners, constructors, and operators of such charging parks are faced with the challenge of ensuring the optimum charging power for each charging point with the limited on-site grid connection. At the same time, a high degree of availability and safety must be ensured, taking other loads and generators into consideration. CHARX manage allows you to overcome this challenge. Manage up to 50 charging points and optimize their operation.

The highly efficient load management ensures the equal distribution of the available connected load to up to 50 AC and DC charging points. This protects your grid connection against overload and the distribution grid against unbalanced loads.

Instead of equal distribution of the charging power to all charging points, you can prioritize individual users based on four levels ranging from high to low. This can be useful for short-stay or VIP guests, for example.

Connect to cloud-based services via the integrated Open Charge Point Protocol (OCPP). These services include user authorization as well as the transfer of charging data for billing purposes, for example.

Charging stations in front of a building are connected to the building management system

If the charging stations are part of the building infrastructure, it makes sense to connect them to a building management system. The system dynamically allocates the available charging current through the charging park based on the needs of the other loads.

Convenient control Intuitive operation is just a few clicks away

Your charging park can be commissioned, configured, controlled, and monitored using a web browser. With just a few clicks, you can manage users and charging points, authorize charging processes, and perform many other tasks – whether from a conventional desktop PC setup or while using a tablet on the go over a secure VPN connection. The intuitive web interface combines all the functions required for system operators, service technicians, and operating personnel.

Charging made easy User guidance via touch screen

If desired, users of your charging stations can be led through the process at a central terminal via touch screen, from authorization to completion of the charging process. CHARX manage records all relevant energy and transaction data during the charging process and stores it in a local SQL database before transferring it to the backend provider via OCPP. The touch interface can also be customized with your logo and preferred colors on request, making it an integral part of the uniform branding concept and image for your charging park.

Clever connection Network the charging park and the building

As an option, you can connect CHARX manage to a building and energy management system, for example Emalytics from Phoenix Contact. By dynamically specifying the maximum charging current and exchanging additional real-time data, you can optimize the interaction between the building and the charging park, thereby avoiding peak loads. You can therefore charge electric cars in a CO₂-neutral manner with self-generated photovoltaic electricity. At the same time, you can make sure that sufficient energy is reserved for loads in the building.

Implement your charging park with us How it works

1. Choose the software license
You can purchase graded software licenses for 5 to 50 charging points to suit the size of your charging park. Affordable upgrade licenses are available for any future expansion. This enables you to invest for the future effectively and develop your charging options flexibly.

2. Choose the industrial PC
Depending on the architecture of your charging park, you can choose between two industrial PCs that deliver the appropriate hardware performance. Choose a panel PC for central authorization with touch operation at the terminal. A box PC is the right choice for charging parks without authorization or with decentral authorization directly at the charging point. It will take you just a few minutes to install the software on the PC.

3. Choose the charging controller
We provide charging controllers compatible with the type of charging and the range of functions required, plus numerous other components for setting up your charging points. You connect them to the industrial PC via Ethernet.
