What is the Japanese DC quick charging standard?

• A. JARI
• B. TEPCO
• C. SAE
• D. CHAdeMO

Answer: (D)

CHAdeMO is the Japanese DC quick charging standard. It’s a DC fast-charging protocol and connector developed in Japan to deliver direct current straight to the battery, allowing a vehicle to charge much faster than with an onboard AC charger. The name comes from “Charge de Move,” reflecting the goal of quick, mobile charging. It was driven by TEPCO and automotive partners like Nissan and Mitsubishi for early Japanese EVs such as the Leaf and i‑MiEV, and it became a widely recognized standard in Japan and many other markets. In contrast, other options represent organizations or utilities rather than the charging protocol itself, and SAE refers to American/industry standards (not the Japanese DC standard). Today CHAdeMO remains one of the major DC fast-charging options alongside others like CCS, though adoption has varied by region.
