Industry groups from Japan and China are teaming up to standardize next-generation quick chargers for electric vehicles (EVs), which are expected to become the global norm.

Japan's CHAdeMO Association said Aug. 22 that it will develop the standards with the China Electricity Council and aims to put them into practical use by 2020. The two groups will sign an agreement in Beijing on Aug. 28.

Japan and China together control more than 95 percent of the global market for ultra-fast chargers.

If China, the world's largest EV market, adopts the same standards as Japan, Japanese automakers will be able to cut costs on developing quick chargers.

It will also become easier for Japanese makers of charging equipment to break into the Chinese market.

The CHAdeMO Association and the China Electricity Council plan to develop the unified standards for an electricity output of more than 500 kilowatts, 10 times more than the current output under the Japanese standards, called CHAdeMO.

Once the next-generation standards are commercialized, a single device will be able to simultaneously quick-charge several electric vehicles.

In addition, the time required for charging will be slashed from the current 30 minutes or so if the performance of onboard batteries improves.

A three-way competition has been developing over the fast charging standards among China's GB/T, CHAdeMO, and the Combined Charging System (Combo), promoted by the United States and Europe.

As of April 2018, GB/T led the market with 220,000 chargers installed, followed by 18,000 units for CHAdeMO and 7,000 units for Combo.

Japan has provided basic technologies for GB/T, which has much in common with CHAdeMO.
