The invention discloses a vehicle charging system and a control method of the vehicle charging system, and relates to the technical field of vehicles. The vehicle charging system comprises a first distribution circuit, a second distribution circuit, a load circuit, an electric drive system and a direct current charging base, the first distribution circuit comprises a first power battery pack, a second power battery pack and a switching circuit, and the switching circuit comprises a parallel cathode switch, a parallel anode switch and a series switch. The lowest parallel voltage after the first power battery pack and the second power battery pack are connected in parallel is larger than a preset voltage threshold value, the switching circuit is used for controlling the electric connection relation of the first power battery pack and the second power battery pack, and the second power distribution circuit comprises a fast charging positive electrode switch and a fast charging negative electrode switch. The second distribution circuit is used for controlling the charging state of the vehicle charging system. The electric drive system is used for driving a vehicle where the vehicle charging system is located to run. The technical problem of high cost caused by the fact that a motor and a motor controller are used for high-power boost charging of a vehicle in the prior art is solved.
