What is the Combined Charging System (CCS)?

Here’s an overview of its principal characteristics.

The Combined Charging System (CCS) is based on open and universal standards for electric vehicles. The CCS combines single-phase with rapid three-phase charging using alternating current at a maximum of 43 kilowatts (kW), as well as direct-current charging at a maximum of 200 kW and the future perspective of up to 350 kW – all in a single system.

The CCS includes the connector and inlet combination as well as all the control functions. It also manages communications between the electric vehicle and the infrastructure. As a result, it provides a solution to all charging requirements.


The key features of the Combined Charging System include the following: 

  • AC charging:

    • With the electrical interface specification for power transmission, which includes safety-related signalling for AC charging that complies with the international IEC 61851-1 standard
    • With a connector Type 2 in Europe that is compliant with the international IEC 62196-2 standard

  • DC charging:

    • With the electrical interface specification for power transmission, which includes safety-related signalling for DC charging that complies with the international IEC 61851-23 standard.
    • With the connector Combo 2 in Europe, compliant with the international IEC 62196-3 standard

  • The communication interface between the electric vehicle and the charging point, based on the international standard ISO/IEC 15118 and the German DIN SPEC 70121.
