This seems like a good idea. There are not enough EV's on the road yet to justify the cost of such a charging truck, so perhaps it needs to be subsidized by the government, similar to chargers, in order to be able to deal with powerless EV's stuck on a highway. I'd also like to see compact gasoline generators or spare battery packs that could be used to get 10-15 miles of range and stored in a trunk or on a rear deck.
