The invention provides an energy-storage type vehicle charging system. The system comprises a charging controller, an energy accumulator and a power supply rail, wherein the first end of the charging controller is connected with the access end of a power grid, the second end of the charging controller is connected with the energy accumulator, and the third end of the charging controller is connected with the power supply rail for judging whether a vehicle to be charged is connected with the power supply rail or not, wherein the energy accumulator is controlled to charge the vehicle to be charged if so, and the power grid is controlled to charge the energy accumulator if not. The power grid is controlled to charge the energy accumulator when the vehicle does not reaches the station, and the energy accumulator is controlled to charge the vehicle when the vehicle reaches the station; and high-current power supply for the power grid is not required since the time that the vehicle does not reaches the station is certainly more than the charging time, so that cable aging is retarded, the impact on the power grid is relatively small, and the problem of exceeding short-term power of the power grid can be prevented.
