Standard or regulation
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.
H
High Power Charging (HPC)
High Power Charging refers to very high-output DC charging intended to add energy quickly during short stops. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.
M
Megawatt Charging System (MCS)
Megawatt Charging System (MCS) is a high-power DC charging system developed for heavy-duty electric vehicles, particularly electric trucks and other applications that need very large amounts of energy transferred during short charging stops. It uses a dedicated high-current connector and is being standardised internationally, including within the IEC 61851 series.
R
Rapid Charging
Rapid charging generally refers to higher-power charging intended to add significant range in a shorter period, commonly using DC infrastructure. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.
U
Ultra-rapid Charging
Ultra-rapid charging describes very high-power DC charging designed for short dwell times and high energy transfer. It is normally assessed alongside charging mode, AC/DC architecture, power rating, connector type and how the charger shares or delivers power.
