Initially, these accessed the abundant AC mains electricity using a variety of plugs around the world. The revival of interest in electric cars spurred deployment of charging stations. Ĭompeting charging systems for high-power DC charging include CHAdeMO (widely used in Japan, previously used in North America and Europe) GB/T (China), and the North American Charging Standard developed by Tesla. 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, Īs well as Ford and General Motors through the 2024 model year for their North American EVs. 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.Įlectric 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. The Combined Charging System allows AC charging using the Type 1 and Type 2 connector depending on the geographical region. 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. 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. It can use Combo 1 ( CCS1) or Combo 2 ( CCS2) connectors to provide power at up to 350 kilowatts (kW) (max 500 amps).
The Combined Charging System ( CCS) is a standard for charging electric vehicles. Typical Combined Charging System (Combo 2) vehicle inlet Two large direct current (DC) pins are added below, and the four alternating current (AC) pins for neutral and three-phase are removed.
