EV Charging Terminology

Simultaneous charging means more than one vehicle can charge at the same time from a multi-outlet charger or grouped charger system. It is normally assessed against site capacity, maximum demand, charger grouping and the behaviour expected when electrical demand changes.

Single-phase charging uses a single-phase AC supply, commonly found in many UK domestic and small commercial installations. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.

Standard or slow charging describes lower-power charging, typically associated with domestic or long-dwell AC charging. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.

Standard Plus or fast charging describes higher-power AC charging, often around 7 kW to 22 kW depending on supply and charger capability. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.
