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.
