Electric vehicle charging station with a field upgradeable communications facility
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.
1. An electric vehicle supply equipment (EVSE) charging station comprising:
a sealable housing including a first compartment adapted to house high power electrical components and a second compartment adapted to house non-high power electrical components formed in part by a lid, the second compartment including an access to an upgrade port wherein a communication module is adapted to couple to the upgrade port within the second compartment accessible under the lid;
a partition within the housing that is adapted to insulate the first compartment from the second compartment; 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.
2. The EVSE charging station of claim 1 further including 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 charging station of claim 1 wherein the sealable housing is adapted to seal both the first and second compartments against weather.
4. The EVSE charging station of claim 1 wherein the second compartment is adapted to be field accessible.
5. The EVSE charging station of claim 1 wherein the communication module includes a Wi-Fi protocol communications capability.
6. The EVSE charging station of claim 1 further including a built-in communications circuit included within the EVSE charging station control circuit.
7. A method of providing a field upgradeable electric vehicle supply equipment (EVSE) charging station, the method comprising:
providing an EVSE charging station including a sealable housing including a lid, a high power compartment and a field accessible compartment accessible under the lid, the field accessible compartment including an access to an upgrade port;
providing a partition within the housing that is adapted to insulate the high power compartment from the field accessible compartment;
providing a communication module adapted to be coupled to the upgrade port, the communication module contained within the second compartment accessible under the lid and to provide communications functionality to the EVSE charging station when the communication module is coupled to the upgrade port; and
configuring a control circuit of the EVSE charging station to recognize a communication module coupled to the upgrade port and to use the communication module for communications if the communication module is connected.
8. The method of claim 7 wherein the field accessible compartment is adapted to house non-high power electrical components.
9. The method of claim 7 wherein the communication module includes a Wi-Fi protocol communications capability.
10. The method of claim 7 further including communicating with a built-in communications circuit included within the control circuit of the EVSE charging station.
