The application provides a battery charging circuit. The battery charging circuit includes a bidirectional vehicle-mounted charging module; a first loop switch module, configured to, once turned on, connect a direct current charging interface of a charging pile to the bidirectional vehicle-mounted charging module's first end, and the bidirectional vehicle-mounted charging module's second end to a battery pack, when the charging pile is charging an electric vehicle; a second loop switch module, configured to, once turned on, connect the direct current charging interface to the battery pack, when the charging pile is charging the electric vehicle; the bidirectional vehicle-mounted charging module, configured to boost a direct current voltage output by the charging pile to be higher than a preset voltage; and a control module, configured to control the first loop switch module or the second loop switch module to be turned on, according to the direct current voltage.
