Information
Definition
Combined Charging System (CCS) is an EV charging system and connector family designed to support both AC and DC charging through a common vehicle inlet concept. Its two main connector variants are CCS1 (Combo 1), used mainly in North America, and CCS2 (Combo 2), which is the relevant CCS format for most UK and European EV charging.
Why it matters
CCS is a widely used umbrella term, but UK specifications normally need to distinguish the general system from the CCS2 connector actually used by most UK rapid and ultra-rapid chargers. Understanding the distinction helps avoid ambiguity when checking vehicle compatibility, charger connectors and international product documentation.
