Electric vehicle charging stations

DEKRA expert tip

The charging of electric vehicles at charging stations, from pedelecs and right up to commercial vehicles, is an inseparable part of the overall concept of e-mobility.

It entails a great deal of hurdles and pitfalls for manufacturers, installers, operators and users alike. For example, it requires working with high currents, which poses issues and makes certain requirements of the charging points and wall boxes regarding safety, ease of use and the service life. All participants can find the help they need at DEKRA.

The German Charging Points Ordinance stipulates the requirements that charging points need to fulfill in order to be installed in public areas. DEKRA’s contributions to safety in regard to the charging infrastructure include, for example, the DEKRA seal introduced in 2012, the first independent testing and certification standard especially created for charging stations for the e-mobility sector. The DEKRA seal for charging points is affixed to the products of those manufacturers who passed the test – much in the same way as a GS mark. This gives potential buyers the security of knowing they are buying a high-quality charging point. DEKRA of course also offers routine on-site inspections in its portfolio.

When a large number of electric vehicles need to be charged simultaneously, the stability of the power supply system becomes an important issue that must be checked.

When a large number of electric vehicles need to be charged simultaneously, the stability of the power supply system becomes an important issue that must be checked. Such testing includes, for example, the circuit feedback. It is vital here to ensure that no power outages can occur as a result of overloading the system.

Owners of electric cars who want to charge their vehicle at home are advised to use a so-called wall box. These allow a quicker and safer charging of the batteries than a standard socket. When choosing and before installing such a system, it is recommended to consult a specialist company or an independent expert, like DEKRA. It is also worth noting that the biggest, most powerful device is not necessarily the best. Most electric cars do not need anything more than 11 kW, for some even 3.7 kW is enough. In most cases, the approval of the property owners is required for an installation in an apartment complex or underground parking. If a charging output over 11 kW is desired, the approval of the power grid operator is also required.
