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.
