Battery storage system and vehicle electrical system for the fault-tolerant supply of safety-relevant consumers in a vehicle

摘要

The invention relates to a battery storage system (20), in particular for a vehicle (10), for the electrical supply of at least one electrical vehicle functions (14, 14a, 14b) to the battery storage system redundantly via a first and a second supply branch (16, 18). 20), having first and second terminals (22, 24) for connection to the first and second supply branches (16, 18), and at least one ground terminal (26, 28), a connection line (32) connecting the first one and the second terminal (22, 24) connects a cross-disconnect switching device (34) disposed in the connection line (32) to interrupt it, a first energy storage unit (40) connected between the first terminal (22) and the cross-disconnect switching device (34) is connected to the connection line (32), and a second energy storage unit (42) connected between the second connection (24) and the cross-disconnect switching device (34) with the Ve Connection line (32) is connected. The invention also relates to a vehicle electrical system (12) with such a battery storage system (20) and a vehicle having such a vehicle electrical system (12).
