Industry jargon

Combined Charging System

Also called: CCS, Combo charging system The Combined Charging System, or CCS, combines AC and DC charging around a shared vehicle inlet and a common charging architecture. In Europe, CCS uses Type 2 for AC charging and Combo 2 for DC charging. In North America, the corresponding legacy CCS configuration uses Type 1 and Combo 1. CCS covers more than the connector shape. The system brings together charging control, power transfer and communication standards, including IEC 61851 and ISO 15118 or DIN SPEC 70121 for higher-level DC communication. IEC 62196-3:2026 is the current IEC standard for high-power DC and combined AC/DC vehicle couplers, including the connector configurations used by CCS.
