What does "EVSE‘ stands for ?
EVSE stands for "Electric Vehicles Supply Equipment", or "Electric Vehicle Service Equipment".
Electric vehicles (EVs), including plug-in hybrid electric vehicles (PHEVs), receive energy from the electrical grid through electric vehicle supply equipment (EVSE), more commonly known as EV chargers. To facilitate the power delivery to the vehicle, the EVSE sits between a stable grid connection and the vehicle.
Electric vehicle service equipment (EVSE) facilitates power delivery to electric vehicles safely from the grid. An EVSE control system consists of an auxiliary power stage, an off-board AC/DC high power stage (only in DC charging stations), energy metering unit, AC and DC residual current detector, an isolation monitor unit, relays and contactors with drive, two-way communication over single wire, and service and user interfaces. This reference design highlights an ultralow standby isolated AC/DC auxiliary power stage followed by converters and linear regulators, a comparator-based control pilot interface to meet the SAE J1772 standard, an efficient relay and contactor drive, and isolated line voltage sensing across the relay and contactor.
