Information
Definition
DC charging supplies direct current to the vehicle battery from off-board charging equipment. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.
Why it matters
It enables rapid and ultra-rapid charging, but requires higher-power infrastructure and different connector, safety and communication considerations. For UK users, it affects charging speed, charger selection, vehicle compatibility and the way power is shared across outlets or vehicles.

EN 61851
EN 61851 is the UK-relevant BS EN IEC standard series for conductive EV charging systems, covering EVSE requirements, charging modes, control functions and safety principles for AC and DC charging. In UK terminology it is often referenced through BS EN IEC adoption and manufacturer compliance declarations.
EN 62196
EN 62196 is the UK-relevant BS EN IEC standard series for EV plugs, socket-outlets, vehicle connectors and vehicle inlets. It underpins terminology around Type 2, CCS and other conductive charging connector formats used in UK charger specifications.
