A power supply system (20, 50) for an electric or hybrid vehicle comprises: a first storage unit (24) coupled to a first electric motor (22) via a first power supply bus (32); a second storage unit (27) coupled to the second electric motor (25) via a second power supply bus (34); a third storage unit (28) coupled to at least one auxiliary electrical load (30) via a third power supply bus (36). The first power supply bus (32) is connected to the third power supply bus (36) via a first diode (40), which is designed to allow only current flow from the first power supply bus (32) to the third power supply bus (36), and the second power supply bus (34) is connected to the third power supply bus (36) via a second diode (42), which is designed to allow only current flow from the first power supply bus (32) to the third power supply bus (36). The second diode is designed to allow only current flow from the second power supply bus (34) to the third power supply bus (36).
一种用于电动车辆或混合动力车辆的供电系统(20,50),包括:第一存储单元(24),其经由第一供电总线(32)耦接至第一电动机(22);第二存储单元(27),其经由第二供电总线(34)耦接至第二电动机(25);第三存储单元(28),其经由第三供电总线(36)耦接至至少一个辅助电负载(30)。第一供电总线(32)通过第一二极管(40)连接至第三供电总线(36),该第一二极管被设计成允许从第一供电总线(32)到第三供电总线(36)的仅有电流流动,并且第二供电总线(34)通过第二二极管(42)连接至第三供电总线(36),该第二二极管被设计成允许从第二供电总线(34)到第三供电总线(36)的仅有电流流动。
