Classification: CPC B  H | IPC B  H

Claim 9:
10. A method of controlling adjusting current load of an electric vehicle supply equipment (EVSE) system:
measuring the current load at a panel current transformer, the panel current transformer connected between a controller module and an electric service panel;
measuring the current load at an EVSE current transformer, the EVSE current transformer connected between the controller module and an output;
comparing the current load at the panel current transformer with the current load at the EVSE current transformer against a predetermined maximum allowable current of the electric service panel; and
adjusting a pilot output signal transmitted by the controller module to the output to adjust the current at the output,
wherein if the current load at the panel current transformer is equal to or greater than 95% of the predetermined maximum allowable current of the electric service panel, then reducing the pilot output signal to the current at the output.
