CHAdeMO might not be U.S. standard?

Sat May 14, 2011 11:24 pm

Is anyone else alarmed by the above article?

Might early adopters get burned by this seemingly political issue (i.e. the big three seem to be trying to screw up the Japanese since they are first to market with quick charge technology) if CHAdeMO doesn't get adopted in the U.S.?

Can anyone within technical expertise comment on the feasibility of simply switching connectors at a later date if necessary? Also, who's going to pay for that retrofit?

When US carmakers get serious about making EVs, this might be an issue. Until then, it's an impediment to building out the quick charge infrastructure.

This is certainly not news. We've been discussing it here off-and-on for at least a year. See this thread, for example:
Level 3 Charging Updates - SAE Meetings

The existence of two competing proposed standards was one key reason I originally planned not to get the QC port. I ended up getting it, and having to pay for it anyway, due to a Nissan foul-up. I still think there is a very good chance I will never use it.

It is totally STUPID to NOT have a world-wide standard. If the US standards committee insists upon a NA-only standard, for NO good technical reason, JUST to make it so that I cannot easily take my car to Europe, I will try to ignore their suggested standard and never again buy one of their products.

With the proposed "US" standard, and a different World standard, then ALL manufacturers will be forced to design their cars for TWO interfaces ... a real WASTE of resources.

If I had a vote (instead of a closed GM-run committee), I would vote NO, by reason of sanity.

If the communication is the same a simple adapter would solve the problem. Perhaps this is why Ecotality and others are dragging their feet.

Curious, but just how often are you driving to Europe?

I'd be happy if I could just drive to Dallas from here.

I smell an opportunity for an adapter here.

This is one of those things where the first-mover has a huge advantage.

If EV Project can get off their acorn and install a few hundred DC stations, then you'd have to be insane to make a car with a different connector that has no infrastructure.

Same reason we still have these awful 120v plugs.

I agree that it is all about critical mass. When they get around to actually voting on this "standard" how many CHAdeMO equipped vehicles are already going to be on the road?

Yes and can you get the US to also switch to the metric system while you are at it?
