Electric vehicle charger energy management equipment for use with generator back-up

A method of managing Electric Vehicle (EV) Supply Equipment (EVSE) power supply from a generator system, the method comprising:

• receiving electrical power to operate at full power;
• monitoring a frequency of electrical power;
• determining that the generator system is supplying power based on the frequency;
• in response to determining the generator system is supplying power, shedding a portion of an electrical load of the EVSE to operate at a percentage of full power;
• delaying increasing the percentage of full power for a period;
• and
• after the period, increasing the percentage of full power.

A system for managing an Electric Vehicle (EV) Supply Equipment (EVSE) for use with a generator system, the system comprising:

• the generator system, wherein the generator system is operable to generate and supply power;
• and
• the EVSE, comprising:
• a controller operable to:
• cause the EVSE to receive electrical power to operate at full power;
• receive an instruction to shed an electrical load of the EVSE and reduce the electrical power received based on a frequency of electrical power powering the EVSE;
• determine a portion of the electrical load to shed based on the instruction;
• cause the EVSE to operate at a percentage of full power;
• delay increasing the percentage of full power for a period;
• and
• after the period, increase the percentage of full power.
