EVSE

Also called: Electric Vehicle Supply Equipment EVSE means Electric Vehicle Supply Equipment, the independently controlled part of a charge point that can supply energy to one electric vehicle at a time. A physical charge point can contain one EVSE or several EVSEs if it can charge more than one vehicle simultaneously. An EVSE can have more than one connector, although those connectors are alternatives for the same charging position and cannot all be used simultaneously. This distinction matters in public charging data, roaming and back-office systems because the physical cabinet, the EVSE and the connector are different objects. For AC charging, the EVSE controls the safe supply of AC power while the vehicle's onboard charger converts that power to DC for the battery. DC charging equipment performs the main AC-to-DC power conversion outside the vehicle.
