Protect your investments in this quickly growing market

Protecting the charging infrastructure and electric vehicles from lightning and surge damage

Electric vehicles - clean, fast and quiet - are becoming increasingly popular. Being involved right from the start is important in many sectors.

The quickly growing e-mobility market is sparking great interest among the industry, utilities, communities and citizens. To be in the black as soon as possible, it is vital to prevent downtime. Therefore, a comprehensive lightning and surge protection concept must be implemented already at the design phase.

Two key aspects to be considered

Talking of protection there are two main issues that have to be taken into account:
Facilities and human life.

  • Protective devices for the charging infrastructure
  • Protective equipment for your employees

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.

Safe working on electric vehicles

Maintenance and repair of charging infrastructure and electric vehicles

The topic of “safe working in the field of electromobility” creates completely new challenges for operators and garages. Employees have to be protected.

Risk of electric arcs

Maintenance and repair of electric vehicles is new territory for many garages. The charged battery in the d.c. on-board power supply, for example, has a considerably higher threat potential than a conventional 12 V system.

The risk of an arc fault when someone is approaching or in case of a short-circuit requires comprehensive protection measures.

Protective equipment for employees

To ensure occupational health and safety, vehicle manufacturers and garages must provide personal protective equipment to their employees.
