The invention relates to the technical field of battery charging and discharging, and discloses a charging circuit and a charging method of a vehicle-mounted power supply and a vehicle. The charging circuit comprises a single-stage PFC circuit, a conversion circuit and a clamp voltage circuit, and the single-stage PFC circuit is used for receiving alternating current of an external network, performing half-wave rectification processing on the alternating current and then outputting sine waves; the conversion circuit comprises a first H-type bridge circuit, a second H-type bridge circuit and a resonance circuit, and is used for performing voltage boosting or voltage reduction adjustment on sine waves output by the single-stage PFC circuit and transmitting the adjusted voltage to the clamp voltage circuit; the clamp voltage circuit comprises a capacitor C and a battery management system, and the battery management system comprises a battery pack; and the clamping circuit is used for filtering the adjusted voltage and carrying out clamping control on the output voltage of the battery pack. According to the design of the charging circuit, a single-stage PFC structure is adopted, an inductor L1 and a capacitor C1 are not included, the space occupied by the L1 and the C1 is avoided, and the cost is saved.
