Little Progress on Global EV Charging System Standard

Support for least three regional regulations for electric vehicle recharging systems will thwart efforts to adopt a single global standard, says The Nikkei.

Support for least three regional regulations for electric vehicle recharging systems will thwart efforts to adopt a single global standard, says The Nikkei.

The Tokyo-based newspaper notes that Japan began developing its CHAdeMo (short for "charge de move") in 2002 and attracted such industry partners as Nissan and Toyota several years later. But efforts to gain broader support faltered.

In the meantime, U.S. and European carmakers have developed their own Combo (short for combined charging system) standard for EV recharging systems. China appears likely to pursue its own regulation for vehicles sold in Asia. Each option requires its own connector and control system.

The Nikkei says Japanese carmakers are heavily committed to the CHAdeMo standard and are not expected to abandon it for EVs they sell in Japan. Like manufacturers elsewhere, they plan to equip their vehicles with the appropriate system for regions in which they are sold until a global standard emerges.
