Zwei-Batteriensystem

摘要

The invention relates to a dual battery system (1) that comprises a starter battery (2) and a battery (3) of the vehicle electric system, a starter (4) and electric consumers that are divided up into start-relevant consumers (7) and consumers (8) of the vehicle electric system. At least one starter switch is interposed between the starter (4) and the starter battery (2). A first, electronically fully locking switch element is interposed between the starter battery (2) and the start-relevant consumers (7) and a second electrically fully locking switch element is interposed between the battery (3) of the vehicle electric system and the start-relevant consumers (7). An element is interposed between the starter battery (2) and the battery (3) of the vehicle electric system that prevents the flow of current from the starter battery (2) to the battery (3) of the vehicle electric system and the consumers (8) of the vehicle electric system.
