Homologation of electric vehicles

DEKRA expert tip

At the DEKRA Electromobility Competence Center in Stuttgart we work intensively on issues and questions pertaining to electromobility.

Electromobility DEKRA

The approval of motor vehicles there is carried out in close cooperation with our colleagues from the DEKRA Automobile Test Center in Klettwitz, who, with their vast knowledge and the required testing technology, create perfect synergy.

The type approval and homologation experts of the DEKRA Automobile Test Center carry out tests on behalf of electric and hybrid vehicle manufacturers (from e-bikes to heavy-duty commercial vehicles) according to the national and international standards, as these must also meet special requirements.

For example, UNECE Regulation 100 has already stipulated requirements on electrical safety for all type-approved vehicles of the categories M or N with a maximum design speed of more than 25 km/h as early as 2016. But individually approved vehicles of these categories with an electric or hybrid drive must also meet these requirements. The tests must show that the electric components (batteries, motor, cables) intended for powering the vehicle do not constitute a hazard.

The tests must show that the electric components intended for powering the vehicle do not constitute a hazard.

For example, it must be proven that the vehicle offers adequate protection against electric shock to all passengers and the driver. By now there are also stringent requirements regarding energy storage: Are the batteries sufficiently protected against vibrations/shocks, short circuits, fire, and thermal influences?

This is why vehicles with both conventional drive systems as well as electric and hybrid drives are subjected to extensive testing in the DEKRA Crash Test Center in Neumünster in order to provide proof that the energy storage system of the vehicle will remain mechanically intact in the case of an accident.

One of the by-products of this type testing is the creation of a rescue sheet for the respective vehicle types, which should be kept in the vehicle. This rescue sheet also shows the high-voltage components in the vehicle, which can be used as an orientation aid for firefighters in the case of an accident or by the workshop for the repair work. These sheets can be downloaded from the DEKRA website at There is also the possibility of ordering a windshield sticker which indicates the presence of a rescue sheet.
