Standalone or networked electric vehicle supply equipment (EVSE) to detect and stop arcing before it becomes dangerous

A method for supplying electricity to an electric vehicle (EV) being a load, the method comprising:

• providing an electric vehicle supply equipment (EVSE) comprising:
• a short-range wireless radio coupled to a processor and the short-range wireless radio coupled to an antenna to provide short-range wireless communications between the EVSE and one or more external devices;
• a coupler;
• and
• an arc fault detection circuit interruption (AFCI) device including:
• a controller including the 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 electric vehicle (EV),
• compare the arcing level to a threshold level to determine a hazardous nature of arching, and
• accumulate information about a level of arcing, a duration of arcing, a number of times arching happened to predict the health of the coupler based on arc energy.
