Abstract
A vehicle electrical system includes at least one battery, at least one fan and a device for detecting a critical state in the vehicle electrical system. The fan is activated when a critical state of the vehicle electrical system is detected. In this context, use is made of the fan's ability to store mechanical energy in the form of inertias. The fan operates in a regenerative manner and electrically feeds the mechanically stored energy back into the on-board electrical system.
