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.
