Document Type and Number:
WIPO Patent Application WO/2023/122937
Kind Code:
A1
Abstract:
Embodiments of the present application provide a battery charging circuit, applied to an electric vehicle. The battery charging circuit comprises: a bidirectional vehicle-mounted charging module; a first loop switch module, the first loop switch module being used for in an on state, electrically connecting a direct-current charging interface of a charging pile to a first end of the bidirectional charging module and electrically connecting a second end of the bidirectional charging module to a battery pack of an electric vehicle, during the charging of the electric vehicle by the charging pile; a second loop switch module, the second loop switch module being used for in an on state, electrically connecting the direct-current charging interface of the charging pile to the battery pack of the electric vehicle, during the charging of the electric vehicle by the charging pile; the bidirectional vehicle-mounted charging module being used for boosting a direct-current voltage output by the charging pile to a voltage higher than a preset voltage; and a control module, the control module being used for controlling, according to the direct-current voltage of the charging pile, the first loop switch module to be turned on or the second loop switch module to be turned on.
