As most of my current projects rap up, I might suggest this as a project for the Dallas Makerspace. Especially since one member already has a Nissan Leaf.
I'd also like to see a DIY EV interface for CHAdeMO. I was thinking something more along the lines of, for example, a Mbed for CAN bus integration and battery management.
I may also suggest that we forward our results to Tesla's Engineers so that we can have official support and develop an interface for the Roadster, Model S, and future Vehicles.
The number of CHAdeMO chargers is still quite small. Even if Nissan does end up rolling out 1000 chargers by the end of 2012, that's still not an insurmountable lead. The number of CHAdeMO capable vehicles out right now in the US is historically large (in the 10k/year range), but it can be easily eclipsed in the future as BEV volumes grow to the 100k/year range. I expect the US government will put their full support on J1772-DC once it is ready (supposedly it will be by the end of this year) and all other DC standards will fall to the side (just like what happended with J1772). The fact that the Tesla connector likely supports J1772-DC via adapter also helps.It will be interesting to see how the CHAdeMO verses J1772-DC "war" plays out in North America. We already have a few CHAdeMO chargers, and lots (by historical EV standards) of CHAdeMO vehicles. Plans to install a lot more CHAdeMO chargers in the near future have been announced. Nissan and Mitsubishi are rolling out their CHAdeMO vehicles nationwide. Expect CHAdeMO vehicles to really ramp up.
CHAdeMO Specification to be open as a Technical Specification (TS) of JIS
August 28, 2012
On August 23, Japanese Industrial Standards Committee (JISC) held its Automobile Technology Committee to decide that the CHAdeMO standard specification for DC fast chargers shall be issued as its Technical Specification (TS).
This is a part of CHAdeMO activities voted on at the 2012 General Assembly: to propose CHAdeMO Specification to JIS, while keep working on IEC to be admitted in its international standard. The official JIS Technical specification (TS) is scheduled to be published shortly, if all goes as planned.
Being approved as JIS TS allows the specification to be disclosed faster than the normal JIS standard process, and ahead of the anticipated IEC publication next year. CHAdeMO shall be recognized, and made open as an official standard of Japan. Moving ahead from its current status as a private standard, this is expected to contribute to garnering more active international supports for CHAdeMO.
