车载电源供给系统向大电力负载和小电力负载供应电力。车载电源供给系统包括:第一供电单元,用于输出具有高于大电力负载和小电力负载所需的总电源电压的第一电压的电力;区域管理单元,用于管理车辆上的预定区域;电源干线单元,其将第一电源单元与区域管理单元相连接;以及降压转换单元,其设置在区域管理单元中的一个区域管理单元的区域中,并将具有第一电压的电力转换为具有低于第一电压的第二电压的电力。电源干线单元包括高压电源线,以分配具有第一电压的电力。

    An in-vehicle power supply system supplies electric power to a large electric power load and a small electric power load. The in-vehicle power supply system includes a first power supply unit to output electric power having a first voltage higher than a total power supply voltage required by the large and small electric power loads, zone management units to manage predetermined zones on the vehicle, a power supply trunk line unit connecting the first power supply unit and the zone management units and a step-down conversion unit disposed in a zone of one zone management unit of the zone management units and to convert the electric power having the first voltage into electric power having a second voltage lower than the first voltage. The power supply trunk line unit includes a high-voltage power supply line to distribute the electric power having the first voltage.
