What Technology Could Improve Electric Automobiles?

With the wide push towards clean fuel and a lower dependence on gasoline in American automobiles, we thought it would be interesting to open a forum for technology that can help improve the quality of our EV automobiles.

Can you think of anything that would improve battery life, make charging easier, or get better efficiency out of an electric vehicle?

Take, for example, the following accessory for an electric vehicle, which is designed to improve battery life provide small charges while on the go. It is a simple, yet wildly functional idea. By attaching small wind turbines to the roof of the car, one can create electricity with the movement of the vehicle.
