An in-vehicle power supply system (100) is provided with a battery (10) and a voltage conversion module (40), and when a charger (50) and the battery are connected via the voltage conversion module, the charging voltage from the charger is converted by the voltage conversion module and supplied to the battery for charging. The voltage conversion module is insulated from a vehicle-side ground (G1), the voltage conversion module has a ground line (G2) connected to a charger-side ground (G3), and the ground line is provided with an energization cut-off unit (42) that cuts off energization in the ground line when a current equal to or greater than a rated current flows therethrough and cuts off the energization in the charger-side ground (G3) when a current equal to or greater than a rated current flows therethrough. The ground wire is connected to the vehicle-side ground member via the energization cut-off unit.

    一种车载电源系统(100),包括蓄电池(10)和电压转换模块(40),在充电器(50)与上述蓄电池经由上述电压转换模块连接时,通过上述电压转换模块对来自上述充电器的充电电压进行转换并供给至上述蓄电池进行充电。上述电压转换模块与车辆侧接地件(G1)绝缘,上述电压转换模块具有与充电器侧接地件(G3)连接的接地线(G2),在该接地线上设置有通电切断部(42),上述通电切断部在流过额定电流以上的电流时切断上述接地线中的通电,上述接地线经由上述通电切断部与上述车辆侧接地件连接。
