A charging circuit includes at least two groups of DC/DC converters, at least one group of relay switches, and at least one diode that are mutually coupled. The relay switch is configured to connect the at least two groups of DC/DC converters in series when a first voltage is in a first threshold range. The first voltage is a charging voltage of an electric vehicle. The relay switch is further configured to connect the at least two groups of DC/DC converters in parallel when the first voltage is in a second threshold range. The diode is configured to prevent a current of a storage battery in the electric vehicle from flowing back. In embodiments of this application, a volume of a charging apparatus can be reduced.
