Abstract

An electric vehicle supply equipment (EVSE) charging system includes an EVSE charging station that is configured to be coupled to an electric vehicle (EV). The charging system further includes an EVSE cloud server coupled to the EVSE charging station optionally via a charge management network. The EVSE cloud server may automatically determine a charging routine for the EV based on historic rate and charge data of the EV and enable a user to interactively modify the charging routine in real-time. The charging routine may provide one or more charging options to the user based on a desired trade-off between different charging cost structures and the required time to charge the EV.

Claims

1. An electric vehicle supply equipment (EVSE) charging system comprising:

an EVSE charging station configured to be coupled to an electric vehicle (EV); and

an EVSE cloud server coupled to the EVSE charging station optionally via a charge management network,

wherein the charging routine to provide one or more charging options to the user based on a desired trade-off between different charging cost structures,

wherein the one or more charging options includes an option to charge that targets arbitraging charging activity and managing demand charge costs, and

wherein the option to charge includes a first routine that both limits power of charging and delays charging, a second routine that prioritizes between limiting power of charging and delaying charging and a third routine that does not limit power of charging and does not delay charging.

2. The system of claim 1, wherein the historic rate and charge data is based on historical timestamps, a user profile, an EV profile and utility rate profiles.

3. The system of claim 1, further comprising:

a smart meter coupled to the EVSE charging station and a power grid, the smart meter to provide the historic rate and charge data of the EV.

4. The system of claim 1, wherein the different charging cost structures are provided by a utility to enable tailoring of a charging process.

5. The system of claim 1, wherein the different charging cost structures are based on a rate of charge, a cost of the rate of charge and a variable energy pricing.

6. The system of claim 5, wherein the variable energy pricing is a tiered energy pricing.

7. The system of claim 1, wherein the one or more charging options includes a first option to charge with all most no regard to the cost of charging the EV.

8. The system of claim 1, wherein the one or more charging options includes a second option to charge that targets managing demand charge costs.

9. A method of charging an electric vehicle (EV) with an electric vehicle supply equipment (EVSE) charging station, the method comprising:
