Abstract

An electric vehicle charging station with a field upgradeable communications facility is provided. The invention includes a sealable housing including a first compartment and a second compartment, the second compartment including an access to an upgrade port; a partition within the housing that is adapted to insulate the first compartment from the second compartment, the partition including an opening providing access the upgrade port; and an EVSE charging station control circuit configured to recognize a communication module when coupled to the upgrade port and to use the communication module for communications if the communication module is connected. Numerous additional aspects are disclosed.

Claims

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

an EVSE charging station including a sealable housing including a first compartment and a second compartment, the second compartment including an access to an upgrade port, a partition within the sealable housing that is adapted to insulate the first compartment from the second compartment, the partition including an opening providing access the upgrade port, and an EVSE charging station control circuit configured to recognize a communication module when coupled to the upgrade port and to use the communication module for communications if the communication module is connected;

a smart meter device including a wireless communication capability adapted to communicate with the EVSE charging station via a home area network (HAN); and

a power supplier adapted to provide electricity to the EVSE charging station and to remotely control the EVSE charging station via commands issued through the HAN.

2. The EVSE system of claim 1 wherein the EVSE charging station further includes a communication module adapted to be coupled to the upgrade port and to provide communications functionality to the EVSE charging station when the communication module is coupled to the upgrade port.

3. The EVSE system of claim 1 wherein the sealable housing is adapted to seal both the first and second compartments against weather.

4. The EVSE system of claim 1 wherein the first compartment is adapted to house high power electrical components.

5. The EVSE system of claim 1 wherein the second compartment is adapted to house non-high power electrical components.

6. The EVSE system of claim 5 wherein the second compartment is adapted to be field accessible.

7. The EVSE system of claim 1 wherein the communication module includes a Wi-Fi protocol communications capability.

8. The EVSE system of claim 1 wherein the EVSE charging station further includes a built-in communications circuit included within the EVSE charging station control circuit.
