Japan has partnered with India to develop an electric-vehicle (EV) charging standard for emerging markets, eyeing easy-to-build stations based on Japanese protocols that would slash installation costs by two-thirds.
The CHAdeMO Association, the organization responsible for Japan EV charging standard, will work with India’s standards drafting committee, which includes such automakers as Mahindra Electric and Maruti Suzuki.
The committee plans to submit a draft proposal to the Bureau of Indian Standards this year, aiming for official adoption as early as 2023.
CHAdeMO — whose roster of roughly 500 member companies includes Nissan Motor, Toyota Motor and Tokyo Electric Power Co. Holdings — hopes to encourage broader use of electric vehicles not only in India but also in emerging Southeast Asian countries now short on the necessary charging infrastructure.
The proposed specifications would allow for a maximum output of 22 kilowatts — half the typical figure for charging stations in Japan.
Simplified construction would facilitate charging from commercial power sources for factories, for example. The cost of installing a charging point, now in the $15,000 to $23,000 range, could be cut to the equivalent of under $10,000.
The lower output means longer charging times — twice as long as standard Japanese chargers for the same battery.
But since electric-vehicle demand in emerging markets is expected to initially center on compact vehicles with relatively low battery capacity, this is seen as likely to be an acceptable trade-off.
Basing the protocol on Japanese standards will let Japanese automakers export models developed for their home market without needing to change the charging connector.
While India plans to have local companies build charging equipment there, other emerging markets that use this standard could order it from Japanese manufacturers, opening up new business opportunities.
India aims to have electric vehicles account for 30% of all new cars sold by 2030, and many Southeast Asian countries also look to pivot to electrics to reduce carbon emissions.
