3.3
Charging terminal
When an electric vehicle is charged, a part of the off-board conductive
charger which needs to be faced and operated by the charging operators,
which generally consists a charging cable, a vehicle plug, a human-machine
interface, which may also include the components of metering,
communication, control, and the like.
