The Combined Charging System was developed to provide a universal solution for EV charging, combining the existing J1772 (Type 1) standard for AC charging with additional DC power pins to enable high-power DC fast charging. CCS connectors come in two variations: CCS1, used primarily in North America, and CCS2, used mainly in Europe and other regions.
CCS allows for both AC and DC charging using the same connector. AC charging is suitable for home and public charging stations, typically providing slower charging speeds that are ideal for overnight charging or extended parking periods. DC charging, on the other hand, offers rapid charging, significantly reducing the time required to recharge an EV’s battery.
The system supports power levels up to 350 kW, facilitating ultra-fast charging that meets the demands of long-range and high-usage vehicles, such as trucks and buses. The CCS infrastructure is designed to ensure interoperability across different manufacturers and regions, making it a key component in the global EV charging network.
CCS is widely adopted by numerous automakers, including Audi, BMW, Daimler, Ford, General Motors, Honda, Hyundai, Kia, Porsche, and Volkswagen, among others. This widespread adoption underscores the system’s importance in the development of a cohesive and efficient EV charging infrastructure.
The Combined Charging System enhances the convenience and accessibility of EV charging, promoting broader adoption of electric vehicles. By supporting both AC and DC charging, CCS addresses various charging scenarios and needs, from home charging to long-distance travel. The integration of high-level communication protocols, such as ISO 15118, further supports advanced features like “plug and charge,” which simplifies the user experience by automating the authentication and payment processes.
