Charging circuit, method and device of low-voltage battery, vehicle and storage medium
The invention relates to a charging circuit, method and device of a low-voltage battery, a vehicle and a storage medium, and belongs to the technical field of batteries. The charging circuit of the low-voltage battery comprises a first winding of a motor, a second winding of the motor, a rectification module and a vehicle control unit, the first winding and the second winding are mutually coupled, energy transmission can be conducted between the first winding and the second winding, the input end of the rectification module is connected with the first winding, and the output end of the rectification module is connected with the low-voltage battery. The actual output torque of the rectifier module is negative torque. Therefore, energy transmission between the motor windings can be realized by utilizing mutual coupling between the motor windings, so that charging of the low-voltage battery is realized, the integration level of the charging circuit of the low-voltage battery is improved, and the charging cost of the low-voltage battery is reduced.
