Abstract
The application discloses an intelligent electric appliance box, a low-voltage power supply system and a vehicle. The intelligent electric appliance box comprises a first battery and a second battery, which are used for low-voltage power supply of the vehicle; a first control circuit, which is used for controlling an electrical connection state of the first battery and the first control circuit and monitoring a state of the first battery; the first control circuit is further used for controlling a first DCDC to supply power to a first load of the vehicle; a second control circuit, which is used for controlling an electrical connection state of the second battery and the second control circuit and monitoring a state of the second battery; the second control circuit is further used for controlling a second DCDC to supply power to a second load of the vehicle; and a circuit switch, which is used for controlling an electrical connection state between the first control circuit and the second control circuit. By using the above intelligent electric appliance box, the first battery and the second battery can be integrated into the intelligent electric appliance box, the first control circuit and the second control circuit are multiplexed, and the cost is reduced.
