The only solution I've heard to the on-the-road charging problem is to "rent" the battery packs instead of owning them, and change out the whole pack at the "recharge station." It's cumbersome, since these things are heavy! You'd either need a crane to replace them from the top, or some kind of lift device to replace them from the bottom. The recharge station then could have a bank of batteries charging and already charged.

Of course, there are problems with this, too. At the recharging station, if you're recharging, for example, 10 batteries at 2C, you'd need 20C charging current, quite respectible. For a 200 Amp-hour pack at 120 Volts (not too far out of range, I believe), that's 4,000 amps, or 480 kW. Better have a substation next door!

That's just part of the question of where the electricity to power all these electric vehicles is going to come from. The energy has to be generated somewhere, either in the car itself through petroleum products, or at the power station and then distributed over the grid.
