The battle between the SAE Combo and CHAdeMO DC fast charger just tipped a little bit toward SAE's "J1772 EV and Plug In Hybrid EV Conductive Charge Coupler." The Car Charging Group is endorsing the new SAE Combo standard that couples a DC fast charger with the J1772 AC 240-volt charger, all in one charging point.
There's no question that the CHAdeMO quick-charging technology standard is a Japanese thing. But the Japanese government wants to take it global, and has thus disclosed more information about the CHAdeMO quick-charging technology standards as a way to encourage CHAdeMO adoption by more automakers. The Ministry of Economy, Trade and Industry would like to see the charging infrastructure grow and EV prices come down by encouraging more competition through a widespread charging infrastructure.

How bad do Europeans want plug-in cars? Nissan is using a campaign called the "Big Turn On" (wink, wink, nudge, nudge) to get people in various cities to compete for a prize of 30 Nissan quick chargers installed in that city. Of course, if Nissan installs a bunch of CHAdeMO quick chargers somewhere, it makes plug-in vehicles like, say, the Leaf, all the more appealing to buyers and a contest like this can only raise the EVs visibility. So, it's a win-win.
Electric vehicles typically come with a home charging cord, and additional stations for 120v or 240v connections are relatively inexpensive. However, when you start trying to cram electrons into a battery in a hurry, the cost can rise steeply. In particular, "Level 3" quick charging stations can be a significant investment, with costs starting around $20,000.
Craig Childers, a zero-emissions specialist at the California Air Resources Board (CARB), said it appears that the U.S. is leaning towards the adoption of a non-CHAdeMO quick-charge standard for plug-in vehicles, according to All Cars Electric. Though Childers admits that this is not a "done deal," he claims that "automotive companies are lobbying for only one opening for powering the car to allow for cleaner design."
The CHAdeMO fast charging protocol was developed by the Tokyo Electric Power Company (TEPCO) along with Toyota, Nissan, Mitsubishi and Fuji Heavy Industries (Subaru), CHAdeMO, a DC fast-charging protocol for electric vehicles, is used for all Level 3 chargers in Japan, but the U.S. has been reluctant to apply this single open standard to govern the quick-charge stations that either already are, or will soon be, installed here. However, according to the Japanese news outlet the Yomiuri Shimbun, t
The CHAdeMO fast charging protocol is an interesting beast. Developed by the Tokyo Electric Power Company (TEPCO) along with Toyota, Nissan, Mitsubishi and Fuji Heavy Industries (Subaru), CHAdeMO is a DC fast-charging protocol for electric vehicles. What's unusual is that any company can use CHAdeMO without paying royalties or any other fees to the developers. Hiroaki Takatsu, TEPCO's executive director, spoke about the technology at the 2010 Driving Sustainability conference in Reykjavík
