Abstract: A low-voltage power supply system includes: a storage battery; an electric control circuit board, the electric control circuit board being connected with the storage battery, a battery management controller (BMC) and a motor controller being integrated on the electric control circuit board, and the motor controller being configured to control a power module; a control circuit being connected with the BMC and being configured to receive a control command of the BMC; a metal-oxide-semiconductor field-effect transistor (MOSFET) connected with the control circuit; and a battery management system. A contactor is arranged in the battery management system. The MOSFET is connected with the contactor and mounted to the electric control circuit board or the battery management system. The BMC is configured to control on/off of the MOSFET through the control circuit, to implement connection/disconnection between the storage battery and the contactor.
