Japanese to standardize EV rechargers

CHAdeMO fast-charging standard aligns automakers and utilities on a common EV charging protocol, enabling interoperability, rapid DC charging, and scalable infrastructure, reducing costs and supporting zero-emissions mobility across Toyota, Nissan, Mitsubishi, and global partners.

Top Japanese carmakers Toyota and Nissan helped set up a group to standardize fast-charge stations for electric cars in a bid to promote the spread of the zero-emission vehicles.

The group, led by Japan's biggest utility, Tokyo Electric Power Co (TEPCO), Toyota Motor Corp, Nissan Motor Co, Mitsubishi Motors Corp and Fuji Heavy Industries Ltd, will set a standard for Japan and later aim for an international standard.

Some 158 companies and government bodies are expected to join, including 20 non-Japanese firms such as PG&E Corp, Enel SpA, Endesa, and PSA Peugeot Citroen.

Electric vehicles (EVs) are seen as one solution to meeting stricter environmental regulations because they have no tailpipe emissions, and automakers are rolling out electric and hybrid models to meet demand today. But they face hurdles such as costly batteries and a limited driving distance compared with conventional cars, as well as the lack of infrastructure to recharge when away from home.

Forming a common "language" for fast-charging electric cars across various brands would save development costs for carmakers and ancillary industries, and aligns with calls for a common EU plug standard for EVs as well, said the group, called CHAdeMO.

"We will compete when it comes to vehicle performance, but we should cooperate on areas such as infrastructure," said Nissan Chief Operating Officer Toshiyuki Shiga, as Nissan plans to test electric car infrastructure in Tennessee soon. Japan's No.3 automaker will begin selling its first electric car, after a Nissan EV rollout at its new headquarters event, later this year.

Mitsubishi Motors and Fuji Heavy, the maker of Subaru-brand cars, are the world's only mass-volume automakers now producing battery-run electric cars, with sales so far limited to corporate and government fleets in Japan.

"There are 1,000 electric cars and 150 fast-charge stations in Japan already," TEPCO Executive Vice President Hiroyuki Ino told a news conference in Tokyo, where car recharging sites are planned next year. "Our aim is to form a standard in Japan and make use of that in the world."

He said the group would lobby international bodies such as the Society of Automotive Engineers and the International Transport Forum to promote its technology.
