High-voltage battery.

The safety concept for the high-voltage battery has been developed to ensure that the occupants do not come into contact with high voltage. A separate, conventional on-board electrical system with a 12 V car battery, shock-proof plugs and continuous monitoring by a dedicated 12 V interlock circuit are employed to this end. In the event of an accident, the high-voltage elements will be deactivated, depending on the severity of impact. In addition, the battery is accommodated in a robust frame in the underbody.
