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

摘要： The present disclosure discloses an integrated controller, an electric drive assembly, and a vehicle. The integrated controller includes: a box; a control unit and a charging/discharging conversion unit that are arranged in the box; and a high-voltage interface assembly, including a high-voltage interface arranged on the box and a high-voltage connection member arranged in the box, the high-voltage connection member being connected with the high-voltage interface, the control unit, and the charging/discharging conversion unit to receive and distribute a high-voltage battery signal. The integrated controller may cancel arrangement of a high-voltage distribution box, which reduces a demand for a high-voltage wiring harness, reduces costs, and saves vehicle space.
