Apparatus and method for redundant power supply in a vehicle

The invention relates to a power supplying apparatus and method for a vehicle, in which a plurality of loads (107, 108) and a plurality of power supplies (100, 115) are connected to each other in such a manner that one of the loads is connected to a plurality of the power supplies, and one of the plurality of the power supplies is connected to a plurality of the loads. Further, the power supplies and the loads are connected through a breaker unit (104, 101, 111, 114) for electrically disconnecting the circuit under predetermined conditions and a unidirectional conductive unit for allowing the current to flow in one direction and blocking the current in the opposite direction.
