Abstract
An electric vehicle supply equipment (EVSE) is provided with an integrated arc fault detection circuit interruption (AFCI) device to supply electricity to an electric vehicle (EV) being a load. The EVSE comprises a coupler and an AFCI device including: a controller including a processor and a memory, circuitry and computer-readable firmware code stored in the memory which, when executed by the processor, causes the controller to: detect an arcing level of arcing between the coupler and a charge port of the EV or any other series or parallel arcing within the EVSE, compare the arcing level to a threshold level to determine a hazardous nature of arching, and analyze the arcing level to determine not only if it is currently hazardous but if it is likely to become hazardous in a near term and recommend repair or replacement of the coupler and the charge port before damage occurs.
