Claim 10:
11. A load adaptive electric vehicle supply equipment (EVSE) system, comprising:
an EVSE unit comprising a controller module, an EVSE current transformer, and an output, wherein the EVSE current transformer is connected between the controller module and the output and wherein the controller module transmits an pilot output signal to the output;
an electric service panel including a panel current transformer, wherein the panel current transformer is connected between the electric service panel and the controller module; and
wherein the controller module is configured to compare current load measurements at the panel current transformer with current load measurements at the EVSE current transformers against a predetermined maximum allowable current of the electric service panel and adjust the pilot output signal to adjust the current at the output, and
wherein the controller module is configured to increase the pilot output signal to a predetermined maximum allowable current at the output if the current at the panel current transformer is less than 95% of the predetermined maximum allowable current of the electric service panel and the current load at the EVSE current transformer is below the predetermined maximum allowable current at the output.
