The invention provides a vehicle-mounted power supply device and a detection method for the vehicle-mounted power supply device. The vehicle-mounted power supply device comprises a primary circuit, a secondary circuit, a transformer, a switching circuit and a control circuit, the primary circuit is connected with two ends of a primary winding of the transformer, two ends of a secondary winding of the transformer are connected with two input ends of the secondary circuit, and the secondary circuit comprises an output port capacitor. The vehicle-mounted power supply device receives power supplied by the power battery to supply power to the first load or receives power supplied by the power battery to supply power to the second load through the switching circuit. And the control circuit is used for controlling the switching circuit to be switched on and controlling the secondary circuit to receive power supply of the primary circuit through the transformer or controlling the switching circuit to be switched off and controlling the secondary circuit to discharge through the transformer. According to the vehicle-mounted power supply device, the power supply safety and reliability of the electric vehicle can be improved.
