DEHN protects e-mobility

Ensuring mobility

Protect the charging infrastructure and electric vehicles from lightning and surge damage according to the requirements of IEC 60364-4-44 clause 443, IEC 60364-7-722 and VDE AR-N-4100.
 
 

Electric vehicles - clean, fast and quiet – are becoming increasingly popular

The quickly growing e-mobility market is sparking great interest in industry, utilities, communities and with citizens. Operators aim to make a profit as soon as possible, so it is vital to prevent downtime. This is done by including a comprehensive lightning and surge protection concept at the design stage.
 
Safety – a competitive advantage

Lightning effects and surges jeopardise the integrity of the sensitive electronics of charging systems. It is not only charging posts which is at risk, but the customer’s vehicle. Downtime or damage can soon get expensive. Beside the repair costs, you also risk losing the trust of your customers. Reliability is the top priority in this technologically young market.

Downtime – Don’t let it come to that

Protect your investment

Protect charging systems and electric vehicles from costly damage

  • To the charge controller and battery
  • To the control, counter and communication electronics of the charging system.

Protecting the charging infrastructure

Protecting the charging infrastructure

Lightning and surge protection for electromobility 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 AC and DC) are currently being installed in private, semi-public, and public areas – 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.

Lightning strikes – 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 just a single lightning strike.

Surges also cause damage

A nearby lightning strike often causes surges which damage the infrastructure. If such surges occur during the charging process, it is highly likely that the vehicle will also be damaged. Electric vehicles typically have an electric strength of up to 2,500 V – but the voltage produced by a lightning strike can be 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 DC on-board power supply, for example, has a considerably higher threat potential than a conventional 12 V system.

Protective equipment for employees

The risk of an arc fault when someone is approaching or in case of a short-circuit requires comprehensive protection measures. To ensure occupational health and safety, vehicle manufacturers and garages must provide personal protective equipment to their employees.
