SYSTEM AND METHOD FOR DYNAMIC ENERGY LOAD BALANCING FOR ELECTRIC VEHICLE SUPPLY EQUIPMENTS
A system and method is provided for managing energy load associated with a group of electric vehicle supply equipments (EVSEs). A server may determine a total load associated with the group of EVSEs. In response to a determination that the total load exceeds a predefined load limit, the server may generate an adjust load signal that is communicated to one or more EVSEs in the group of EVSEs.
1 . An electric vehicle supply equipment (EVSE) comprising:
a sensor configured to measure an amount of current drawn by the EVSE;
a processor configured to:
determine an amount of power used by the EVSE; and
communicate the amount of power to a server.
2 . The equipment of claim 1 , wherein the processor is configured to determine the amount of power used by the EVSE when the EVSE is used for charging an electric vehicle.
3 . A system for managing energy load, the system comprising:
a processor configured to:
receive, by each EVSE in a group of EVSEs, an amount of power used by the EVSE;
determine a total load on an electrical power grid based on the received amount of power used by each EVSE;
determine whether the total load exceeds a predefined load limit;
in response to a determination that the total load exceeds the predefined load limit, generate an adjust load signal; and
communicate the adjust load signal to each EVSE.
4 . The system of claim 3 , wherein processor is further configured to:
identify one or more EVSEs in the group of EVSEs that contribute to the total load; and
communicate the adjust load signal to the identified one or more EVSEs.
5 . The system of claim 3 , wherein the amount of power used by the EVSE is determined based on an amount of current drawn by the EVSE.
6 . The system of claim 3 , wherein the amount of power used by the EVSE is determined when the EVSE is used for charging an electric vehicle.
7 . The system of claim 5 , wherein the adjust load signal comprises an instruction to lower the amount of current drawn by the EVSE.
8 . A method for managing energy load, the method comprising:
receiving, by each EVSE in a group of EVSEs, an amount of power used by the EVSE;
determining a total load on an electrical power grid based on the received amount of power used by each EVSE;
determining whether the total load exceeds a predefined load limit;
in response to a determination that the total load exceeds the predefined load limit, generating an adjust load signal; and
communicating the adjust load signal to each EVSE.
9 . The method of claim 8 , further comprising:
identifying one or more EVSEs in the group of EVSEs that contribute to the total load; and
communicating the adjust load signal to the identified one or more EVSEs.
10 . The method of claim 8 , wherein the amount of power used by the EVSE is determined based on an amount of current drawn by the EVSE.
11 . The method of claim 8 , wherein the amount of power used by the EVSE is determined when the EVSE is used for charging an electric vehicle.
12 . The method of claim 10 , wherein the adjust load signal comprises an instruction to lower the amount of current drawn by the EVSE.
