Abstract
In one or more embodiments, electrical supply systems including Electric Vehicle Supply Equipment (EVSE) are provided. The EVSE includes a communication gateway that provides internet accessibility by a user through an EVSE server. In some embodiments, the EVSE allows communication with other smart devices, and/or communication of status of loads coupled to a load center. The user or the utility service provider can perform, through the EVSE server, energy management and home automation tasks using this communication gateway of the EVSE and may send control signals to smart devices through the EVSE. This EVSE may also provide a protection mechanism for smart devices coupled to the load center in case of emergencies like brown-outs or power surges on the electric grid. Methods of operating the system and EVSE are provided, as are other aspects.
