Assignee: POWERTREE SERVICES, INC.
Field: Transport (Mechanical engineering)
Classification: CPC B  H | IPC B  H

Claim 0:
1. 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 a 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 reduce the pilot output signal to the output 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.
