CHAdeMO (an abbreviation of "CHArge de MOve," a play on the Japanese phrase for "How about some tea?" — referencing the time it takes to charge) is a DC fast charging standard developed by a consortium of Japanese automakers including Nissan, Mitsubishi, Toyota, and TEPCO.
Launched in 2010, CHAdeMO was the first widely deployed DC fast charging standard. It uses a distinctive round connector separate from the vehicle's AC charging port. Early CHAdeMO stations delivered 50 kW, while the latest specification (CHAdeMO 2.0) supports up to 400 kW, though most deployed stations operate at 50-100 kW.
In North America, CHAdeMO adoption has declined significantly. The Nissan LEAF was the primary vehicle using CHAdeMO, but Nissan has transitioned to CCS and NACS for newer models. As of 2025, most new DCFC installations no longer include CHAdeMO ports, and the NEVI program does not require them. However, thousands of CHAdeMO-equipped stations remain operational, serving the existing fleet of CHAdeMO-compatible vehicles. The standard remains more prevalent in Japan, where it originated.
