ADAC conducts vehicle safety checks and EV charging efficiency studies

ADAC is conducting various initiatives focused on vehicle safety and electric vehicle (EV) efficiency. The organization’s mobile service in Northern Bavaria is offering free vehicle inspections, including checks for brakes and shock absorbers, to help drivers ensure road safety.

In a separate study regarding electromobility, ADAC analyzed charging losses across five different electric vehicle models. The research compared charging via standard household sockets versus wallboxes. The findings indicate that charging from a household socket (2.3 kW) results in the highest energy losses for all tested vehicles.

Specifically, the Mercedes-Benz CLA EQ was identified as the least efficient, with nearly a quarter of the consumed electricity failing to reach the battery. Other vehicles experienced losses of approximately 15 percent. The study also noted that charging with surplus power from photovoltaic systems via a wallbox is more efficient, even when charging power is reduced.
