Japan, China mull unified EV standard

Jiji Press TOKYO (Jiji Press) — Japan and China are working to unify standards for electric vehicle charging systems.

Currently, there are multiple standards in the world, with charging plugs with different shapes used in Europe, the United States and Asia.

If Japan unifies the charging system’s standard with China, which is the largest automobile market in the world, it could virtually gain control over the global standard and help Japanese electric vehicle makers have a competitive edge over their European and U.S. rivals, pundits said.

For standards adopted in fast chargers, Japan uses the CHAdeMO system, while Europe and the United States use the Combined Charging System and China the GB/T system. U.S. electric vehicle maker Tesla Inc. has its own standard.

There were over 18,000 CHAdeMO charging posts in 71 countries as of March this year.
