The invention relates to a charging system and a control method thereof, vehicle-mounted charging equipment and a vehicle. The charging system comprises a power circuit, a first switching circuit, a second switching circuit, a conversion circuit, a power factor correction circuit and a plurality of charging ports. Under the condition that the first switching circuit is switched on and the second switching circuit is switched off, the power battery drives the motor to work through the power circuit; under the condition that the first switch circuit is switched off and the second switch circuit is switched on, the power circuit and the conversion circuit form a DCDC converter, and an external power supply charges the power battery through the charging port, the power factor correction circuit and the DCDC converter in sequence. According to the charging system, the first switching circuit and the second switching circuit are controlled to be switched off and switched on, so that the power circuit can serve as a part of a driving circuit of a motor and can also serve as a part of a charging circuit of a power battery, multiplexing of the power circuit is achieved, the complexity of the charging system is reduced, and the charging efficiency is improved. And the lightweight requirement of the electric automobile is met.
