Protecting the charging infrastructure

Lightning and surge protection for electromobilty charging stations

Charging stations are required where electric vehicles are parked for an extended period of time: at work, at home, at park + ride sites, in multi-storey car parks, in underground car parks, at bus stops (electric busses) etc.

Therefore, more and more charging stations (both a.c. and d.c.) are currently being installed in private, semi-public, and public areas – and consequently there is an increasing interest in comprehensive protection concepts. These vehicles are too expensive and the investments too high to run the risk of lightning and surge damage.

Thunderstorms – Risk for the electronic circuitry

In case of a thunderstorm, the sensitive electronic circuitry for the controller, counter and communication system is particularly at risk. Satellite systems whose charging points are interconnected can be immediately destroyed by a single lightning strike.

Surge damage - What causes it?

A nearby lightning strike often also damages the infrastructure. Therefore, it is highly probable that such surges will damage the vehicle during a charging process. Electric vehicles typically have an electric strength of up to 2,500 V – however, a lightning strike can produce a voltage 20 times higher than that.

Protect your investments – Prevent damage

Depending on the location and type of threat, an individually adapted lightning and surge protection concept is required.

DEHNshield ZP

Type 1 + 2 combined lightning current and surge arresters based on spark gap technology. Quick and easy to mount by snapping onto 40 mm busbar systems. Particularly suitable for use in charging poles and in all operating locations and lightning protection zones according to EN 62305-4.

DEHNshield

Prewired type 1 + type 2 spark-gap-based combined arrester – ideally suited for charging stations/wall boxes. It can be used at all locations and for all lightning protection zones according to IEC 62305-4.

DEHNguard modular

Modular multipole type 2 surge arrester with a functional design for protecting charging stations/wall boxes from indirect lightning effects (inductive, capacitive coupling etc.)

DEHNguard SE DC ...

Modular single-pole type 2 surge arrester for protecting d.c. charging stations from indirect lightning effects (inductive, capacitive coupling, etc.) up to 900 V d.c.

DEHNrail modular

The type 3 surge arrester is typically used for protecting terminal equipment. Different types of housings ensure easy installation close to the terminal equipment.

BLITZDUCTOR XT

Pluggable combined arrester (type 1 + 2) with integrated LifeCheck function for monitoring the arresters for two-pole, three-pole or four-pole interfaces of electromobility equipment.
