CCS (Combined Charging System)

The Combined Charging System (CCS) is a standardized charging solution for electric vehicles (EVs) (North America CCS1 and Europe CCS2) that supports both alternating current (AC) and direct current (DC) charging capabilities into a single connector design. CCS is recognized for its versatility, allowing EVs to charge at a wide range of power levels, from slow AC home chargers to rapid DC fast chargers. CCS was proposed in 2011 by SAE International (Society of Automotive Engineers) and the ACEA (European Automobile Manufacturers Association) CCS aims to simplify and harmonize EV charging infrastructure across regions. The connector design incorporates two additional DC pins for fast charging, while retaining compatibility with standard AC charging pins. This ensures that EVs equipped with a CCS inlet can access a broad spectrum of charging stations, promoting convenience and interoperability. As a result, CCS has become a prominent charging standard in many parts of the world, facilitating the global adoption of electric mobility.
