Information
Definition
Charging mode describes the method by which an electric vehicle is connected to an electrical supply for charging. It covers whether charging is AC or DC, whether dedicated EV supply equipment is used, whether control communication is present, and what level of protection or control exists between the supply and vehicle.
Why it matters
It helps users understand the fundamental charging arrangement, not just the power rating. For most UK charger comparisons, Mode 3 is the key AC mode and Mode 4 is the key DC mode.

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.
