Motor vehicle electrical system for current peak load has local short-term energy storage device in form of capacitor associated with current peak load in decoupled sub-circuit

摘要

The system has a generator, at least one battery and at least one current peak load (6,7) with an associated local short-term energy storage device in the form of a capacitor (8,9) . The current peak load can be arranged in a safety-relevant sub-circuit (10) connected to the remainder of the vehicle electrical system via a decoupling circuit (11).
