A vehicle-mounted power supply system is provided with: first to sixth power supply hubs (11-16) connected to a main power supply line wired from a mounted power supply (2); electronic devices (D11-D14, D21-D25, and D31-D33) connected to the plurality of first to sixth power supply hubs (11 to 16), respectively; and a relay that turns on and off energization to each electronic device. A mechanical relay is used as a relay for an electronic device having a current consumption of 10 A or more, and a semiconductor relay is used as a relay for an electronic device having a current consumption of less than 10 A. The mechanical relay is disposed on the outside of a cabin space surrounded by a waterproof material (S) that cuts off the penetration of water into the cabin from the outside of the vehicle and inside the vehicle body of the vehicle (1).

    车载电源系统,具备:与从搭载的电源(2)配线的主供电线连接的第一电源集线器~第六电源集线器(11~16);分别与多个第一电源集线器~第六电源集线器(11~16)连接的电子设备(D11~D14、D21~D25、D31~D33);以及接通和断开向各电子设备的通电的继电器。对于消耗电流为10A以上的电子设备使用机械继电器作为继电器,对于消耗电流小于10A的电子设备使用半导体继电器作为继电器。机械继电器配置于由防水件(S)包围的车室空间的外侧且车辆(1)的车身内,该防水件切断从车外向车室内的水的浸入。
