Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present application discloses a kind of energy-storage type vehicle charging system, including：
Charge controller 100, accumulator 200 and power rail 300, wherein the accumulator 200 can be by large power energy storage
Element constitutes (such as super capacitor), and high current charge-discharge may be implemented；
The first end of the charge controller 100 is connected with power grid incoming end, the second end of the charge controller 100 with
Accumulator 200 is connected, and third end is connected with the power rail 300, and the power grid incoming end is connected with industrial electrical network power supply；
The charge controller 100 is specifically used for, and judges whether that charging vehicle in need is connected (i.e. institute with power rail 300
Power rail 300 is stated whether to being connected to current collector), if so, needing the electric energy stored using the accumulator 200 to required at this time
The vehicle of charging charges, and the charge controller 100 controls the accumulator 200 and filled to the vehicle of required charging
Electricity, if not, control power grid charges to the accumulator 200 with current constant mode, until the accumulator 200 is filled.
Referring to technical solution disclosed in the above embodiments of the present application, by when vehicle does not enter the station, (power rail 200 is not
Connect vehicle), control power grid charges to the accumulator 200, and when vehicle pull-in, control accumulator fills vehicle
