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.

Abstract: An on-site device configured to be used with networked Electric Vehicle Supply Equipments (EVSEs) is provided to diagnose or recover an EVSE for configuration. The on-site device comprises a first coupler interface configured to electrically connect the on-site device to one or more EVSEs, a first communication interface to connect the on-site device to a short-range communication network on a wired network or on a wireless network. It further comprises a second communication interface to connect the on-site device to a long-range wireless communication network, a processor and a memory storing instructions that, when executed by the processor, cause the on-site device to: establish a communication connection with the EVSE and interface to the EVSE via a programmable logic controller (PLC) on a control pilot, Modbus RTU or other near-field communication (NFC), perform diagnostics to locally recover charging operation or network connectivity of EVSEs and further aid in remote maintenance.

Abstract: A bi-directional electric vehicle supply equipment (EVSE) is provided where the EVSE allows power transfer to and from an electric vehicle (EV). 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.
