Abstract: A charging circuit includes at least two direct current-direct current (DC-DC) conversion circuits coupled between a power supply end and a charging end of the charging circuit. A voltage input end of the DC-DC conversion circuit is coupled to the power supply end, and a voltage output end of the DC-DC conversion circuit is coupled to the charging end. The at least two DC-DC conversion circuits include a first DC-DC conversion circuit and a second DC-DC conversion circuit. The first DC-DC conversion circuit is configured to perform voltage conversion on a voltage at the power supply end, to output a first charging signal to the battery. The second DC-DC conversion circuit is configured to perform voltage conversion on the voltage at the power supply end to output a second charging signal to the battery.
