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.
Claims12
An electric vehicle (EV) charging station for charging an electric vehicle (EV), the EV charging station comprising:
- an AC to DC power converter configure to receive AC power from a power source and convert the AC power to DC power;
- an electric reservoir configured to receive DC power from the AC to DC power converter when the EV charging station is not charging the EV and to store the DC power;
- a DC to DC converter configured to receive DC power simultaneously from both the electric reservoir and the AC to DC power convertor when the EV charging station is charging the EV, the DC to DC converter further configured to convert the DC power to a DC voltage suitable for charging the electrical vehicle;
- a relay switching system configured to select a charging target by (i) connecting or disconnecting the electric reservoir to/from the AC to DC power converter, and (ii) connecting or disconnecting the DC to DC converter to/from the electric reservoir and the AC to DC power converter,
- wherein the relay switching system is controlled to charge the electric vehicle at a maximum available power level utilizing both power from the AC to DC power converter and stored power from the electric reservoir by selectively (i) connecting the AC to DC power converter to the electric reservoir when the EV charging station is not charging the EV and (ii) connecting both the electric reservoir and the AC to DC power convert to the DC to DC converter when the EV charging station is charging the EV.
