Electricity to charge the car is cheap enough. At 10 cents per kwh, an electric vehicle 5-passenger sedan would cost only 2 cents per mile in electricity.
The problem is the 'consumables cost' as long as batteries have relatively short numbers of recharge cycles. An electric vehicle using 50kwh of A123 cells would need its battery pack replaced at 200K miles, at a current cost of $30K. So that 'consumables cost' is 15 cents per mile (even if electricity were free). Total cost equivalent to $5.00 gallon gasoline if the comparable ICE vehicle got 30mpg. If that 50kwh battery pack was only $10K, the total cost would be equivalent to $2.00 gasoline.
