Combined Charging System

A CCS1 (Combined Charging Standard 1) DC charging connector, which is used in North America. It is an extension of the J1772 standard AC charging connector.

The Combined Charging System (CCS) is a standard for charging electric vehicles. It can use Combo 1 (CCS1) or Combo 2 (CCS2) connectors to provide power at up to 500 kilowatts (kW) (max. 1000 V and 500 A).[1] These two connectors are extensions of the IEC 62196 Type 1 and Type 2 connectors, with two additional direct current (DC) contacts to allow high-power DC fast charging. In response to demand for faster charging, 400 kW CCS chargers have been deployed by charging networks and 700 kW CCS chargers have been demonstrated.

The Combined Charging System allows AC charging using the Type 1 and Type 2 connector depending on the geographical region. This charging environment encompasses charging couplers, charging communication, charging stations, the electric vehicle and various functions for the charging process such as load balancing and charge authorization.

Electric vehicles or electric vehicle supply equipment (EVSE) are CCS-capable if they support either AC or DC charging according to the standards listed by the CCS. Automobile manufacturers that support CCS include BMW, Daimler, FCA, Jaguar, Groupe PSA, Honda, Hyundai, Kia, Mazda, MG, Nissan, Polestar, Renault, Rivian, Tesla, Mahindra, Tata Motors and Volkswagen Group,[2][3] as well as Ford and General Motors through the 2024 model year for their North American EVs.[4]

Competing charging systems for high-power DC charging include CHAdeMO (widely used in Japan, previously used in North America and Europe)[5] GB/T (China),[6] and the North American Charging System developed by Tesla.[7]
