Electric Vehicle Fast Charging Stations and Outlets: CCS or CHAdeMO

article photo
DC fast charging is important for reducing the charging times of electric vehicles (EV) and is critical to making long-distance EV travel practical. Although Tesla has a well-developed, proprietary supercharging network, two types of non-proprietary DC fast charging connectors are also used in the United States: SAE Combined Charging System (CCS) and CHArge de MOve (CHAdeMO), the trademark name for a DC charging standard. All other EV manufacturers equip their vehicles with either a CCS or a CHAdeMO charging port, based on manufacturer preference. CCS allows AC/DC charging through the same port, while vehicles equipped with CHAdeMO have a separate port for AC charging. The United States has over 2,600 charging stations with the CHAdeMO and nearly 2,400 stations with the CCS connector. However, when it comes to the number of individual outlets, there are more CCS outlets (over 5,000) than CHAdeMO outlets (close to 4,000).
