GM and Nissan trade punches over electric car fast charging
A big battle is being fought over the charging socket of electric cars, one in which billions of dollars in coming infrastructure expenditures and market share are at stake, as well as the success of mainstream electric vehicle adoption. Today a very instructive pair of salvos were fired during a public California State Senate Committee meeting, chaired by State Senate Majority Leader Ellen Corbett, on the topic of Electric Vehicle Deployment. In the exchange a GM representative called to limit adoption of DC Fast Chargers to only those which conform to the upcoming SAE DC Fast Charge standard, while a Nissan representative described the CHADEMO connector, available on the Mitsubishi i-MiEV and Nissan Leaf, as the only existing fast charging standard, and one that meets the needs of todays market.
The broad ranging committee meeting took testimony on the state of California's electric vehicle deployment, on the manufacturers perspective regarding California's electric vehicle deployment, and on electric vehicle infrastructure issues. The shots between GM and Nissan took only 10 minutes out of the 2+ hours of the meeting, and offered a glimpse into the battle being fought between the automakers for dominance in electric cars.
CHADEMO was developed in Japan, and was first deployed for electric vehicle charging by TEPCO beginning in 2008. Data from that time shows that when the CHADEMO network was installed, electric car utilization shot way up. The assumption is that the existence of fast charging infrastructure goes a long ways to erasing range anxiety, giving electric car owners the freedom of mind to drive their cars. There is every expectation that as fast charging networks are built in the U.S. the same will occur. But there is a battle brewing between two competing standards for DC Fast Charging, the CHADEMO standard being used now by Nissan and Mitsubishi, and the SAE DC Fast Charging standard being pushed by GM and an alliance of 8 total car manufacturers.
