Following the quake in Japan, Nissan announced that its goal is not "becoming a [zero-emissions] car provider, but a creator of ZE society by taking a comprehensive ZE approach." To that end, Nissan unveiled its Leaf-to-home electricity system. And it's not stopping there.

Teaming up with Mitsubishi, Nissan aims to standardize a device that enables electric vehicles to supply power to households. This could be an auspicious partnership, as the unification of standards by two of Japan's leading electric vehicle manufacturers will likely lead to a nationwide standard, reports Yomiuri Online.

Currently, Nissan's Leaf-to-home setup is incompatible with the system that Mitsubishi's electric i-MiEV uses. The same holds true for Mitsubishi's recently unveiled vehicle-to-home system. However, with both automakers teaming up to develop a unified standard, one of the two systems will likely be modified in the near future. Both Nissan's and Mitsubishi's vehicle-to-home systems are slated to launch in Japan by the end of 2011.

      There is a way to get rid of the paint shop all together by using carbon fiber reinforced composites. I think it was Amory Lovins who was explaining it. Supposed to be much cheaper.

      This is how you create standards, by doing stuff - from the same guys that brought you a real Level 3 charging standard.

      ECgrid is working to make the standards and show the value of V2G also read V2G-101.com for the best info.

      This is a good idea. They should try to future proof it to be compatible with a larger V2G (vehicle to grid) capability and even V2V (vehicle to vehicle). I don't see using true V2G any time soon since the cycle life of the batteries is too valuable. But V2H (vehicle to home) for backup power, and V2V to help out a fellow EV, are occasional emergency situations where the value of the use case outweighs the cost of battery degradation.

      ACP has also been working on V2G for years, with many University research partners. But no corporation will set a national standard much less a global one, any more than Chademo will ever be a global standard. Not even SAE will be able to set the V2G standard on their own, because SAE doesn't know the power generation or grid distribution industries. And the grid stability issues vary between countries. The IEEE collaboration with SAE will set the standard in the US, and perhaps ISO will adopt a variation for Europe. Usually the rest of the world follows either SAE or ISO. Sometimes SAE and ISO have mirror image standards. One might get a little ahead of the other, then by the next version, they are synchronized again. It depends on where the next breakthrough occurs. If it happens in the US, then the SAE standard might get ahead of ISO for six months or so. But all this work is good, and everything that the Asian corporations come up with will likely be considered for one aspect or another of the IEEE / SAE or ISO standards eventually. Everyone has something to contribute. And everyone has something to gain from the other guys. Does anyone know of an international standards body for Asia? I see national regulations in Asia of course, but I have not heard of an international automotive (like SAE) or electrical (like IEEE) standards body in Asia yet. Maybe that is why there are videos of exploding natural gas powered buses in South Korea, and EV fires in China.
