Tesla's supercharging stations charge at 135kW 400V DC, recharging >50% of a 85kWH battery in 30 minutes. The power is delivered from a large (>300kWH) battery pack installed in the charging station, which is continously trickle-charged from the grid. There will also be swap stations implemented, swapping out the entire 85kWH battery pack in 2 minutes.
This is largely a solved problem, both from the sides of technology and deployment. It's just that public perception hasn't caught up yet. Give it 5 years and just about everyone will want one of these cars. For everyday use you won't even need the quick-charge capability.

They sold a batch of MiEV / IOn for $15.000 here and so far everybody is very enthusiastic about them. I think 5 years is a tad optimistic but I give it less then 10 years.
And how do you cool the battery during such a fast charge? what % of the energy is lost in heat from the chemical reaction - even Tesla has to obey the laws of thermo dynamics.
Thinking about it from a thermofluids angle You could I suppose have a complex system of heat exchangers built in to the the battery pack and hook the car up to a water connection and flush chilled water (or better some non conductive fluid) through whilst charging but water and high voltage and amps are not the best of friends.
Now where did i put my steam tables :-)
