Open charging station with charging cables

Charging electric vehicles safely and without interruptions Comprehensive protection concept

The charging infrastructure for electric vehicles is just as complex as the vehicle itself. From the power supply and components for visualizing the charging process to the cables for Ethernet communication, the charging station is equipped with a large number of important and sensitive components. They need to be protected to ensure that the charging infrastructure has a long service life and that the charging process is uninterrupted.

A comprehensive protection concept therefore consists of three areas:

The type 1 and type 2 combined lightning current and surge arresters and type 2 protective devices for the power supply protect feed-in against dangerous overvoltages caused by lightning strikes and switching operations from the grid.
Use type 3 surge protective devices to ensure the long-term function of numerous sensitive components within your charging station.
The communication components are usually connected over Ethernet and should also be protected.

Protecting the feed-in

If you can rule out the possibility of direct lightning strikes to the charging station or home charger, a type 2 protective device provides sufficient protection for your application. The VAL-EV-T2 surge protective device, designed specifically for this type of application, ensures reliable feed-in. The connected vehicle is also protected, and the charging process can be continued without interruption if any overvoltages occur.

Protecting the feed-in – even from lightning strikes

The VAL-EV-T1/T2 lightning current and surge protective device, designed specifically for charging stations, provides safe and reliable protection against overvoltages caused by lightning strikes and switching operations. The high voltage peaks on the supply lines caused by an overvoltage can result in damage to equipment and the connected vehicle. The surge protection limits these voltages via the varistor-based combined lightning current and surge arrester, which ensures permanent availability.

Feed-in protection – especially for home chargers

CHARX-PROTECT-11-22 KW is the optimal surge protection for home chargers in the carport: The type 2 arrester integrated into the IP65 housing protects home chargers with charging capacities of 11 to 22 kW as well as the connected vehicle against expensive damage due to voltage peaks that can be caused by lightning strikes or switching operations in the supply grid. The weatherproof and impact-resistant box can be installed in weather-protected outdoor areas, for example in the carport. To match the existing cable routing, the feeding AC cable can be fed into the housing either at the top or at the bottom. Internal wiring is particularly fast thanks to the push-in connection.

Directly to the product

Protecting sensitive components

Many components in charging stations with a 24 V power supply are sensitive and susceptible to voltages that are too high. Protect these components with a type 3 surge protective device. The PLT-SEC for 24 V DC can be installed quickly thanks to the proven Push-in connection technology.

Protecting the Ethernet communication

It is not just in public spaces that charging stations are often equipped with components for communication with billing or building management systems, such as cellular modems or Ethernet switches. Even these devices are sensitive to overvoltages. The DT-LAN surge protective devices for information technology provide the ideal solution here. The Ethernet cables are protected and operation is ensured.

Protective device for PCB mounting

The VAL-MS-BE PCB base element is designed for direct mounting on a printed circuit board. It is equipped for all protective plugs in the VALVETRAB MS product range. The protective plugs for the VAL-EV surge protective devices, designed specifically for charging stations, can also be used here. This range includes T1+T2 combined lightning current and surge arresters as well as type 2 surge protective devices.
