Abstract

An electric vehicle (EV) charging station for fast charging (e.g. 5 to 15 minutes) an electric vehicle (EV). The EV charging station can be configured to charge multiple EVs and multiple conventional vehicles at the same time. The EV charging station can include a power source, an electric reservoir receiving power from the power source, an AC to DC power converter for receiving AC power from the power source and converting the AC power to DC power for supplying DC power to the electric reservoir, an EV charger receiving DC power from the electric reservoir; and a first DC to DC converter receiving DC power from the electrical reservoir and converting the DC power to DC power suitable for charging the electrical vehicle.

Claims

1. An electric vehicle (EV) charging station for charging an electric vehicle (EV), the EV charging station comprising:

a power source;

an electric reservoir receiving power from the power source;

an AC to DC power converter for receiving AC power from the power source and converting the AC power to DC power for supplying DC power to the electric reservoir;

an EV charger receiving DC power from the electric reservoir; and

a first DC to DC converter receiving DC power from the electrical reservoir and converting the DC power to DC power suitable for charging the electrical vehicle.

2. The station according to claim 1, wherein the AC to DC converter comprises a rectifier for converting the AC power from the power source to DC power, a second DC to DC power converter for converting the DC power from the rectifier to DC power suitable for charging the electric reservoir.

3. The station according to claim 1, wherein the AC to DC converter comprises an electric filter receiving DC power from the second DC to DC converter prior to supplying power to the electric reservoir.

4. The station according to claim 3, wherein the electric filter is an LC filter.

5. The station according to claim 1, wherein the electric reservoir comprises a flow battery.

6. The station according to claim 1, wherein the electric reservoir comprises a Li-ion battery.

7. The station according to claim 1, wherein the EV charger receives power from the electrical reservoir and/or Li-ion battery.

8. The station according to claim 5, wherein the electrical power reservoir comprises a Li-ion battery.

9. The station according to claim 1, wherein the EV charger comprises a Li-ion battery.

10. The station according to claim 9, wherein the EV charger is configured to selectively provide power for charging the EV from the electric reservoir or the Li-ion battery of the EV charger.

11. The station according to claim 9, where the EV charger is configured to simultaneously provide power for charging the EV from both the electric reservoir and the Li-ion battery of the EV charger.

12. The station according to claim 1, wherein the station is configured to selectively provide power to the first DC-DC converter from the electric reservoir or from the AC to DC power converter.

13. The station according to claim 1, wherein the station is configured to simultaneously provide power to the first DC-DC converter from the electric reservoir and the AC to DC power converter.

14. The station according to claim 1, further comprising an electronic controller located between the power source and electric reservoir for controlling charging of the electric reservoir.

15. The station according to claim 1, wherein the AC charger comprises a gas pump.

16. The station according to claim 1, wherein the station comprises multiple EV chargers spaced apart and arranged in rows, and the multiple EV charges each comprise a gas pump.
