Abstract

As fossil fuel prices steadily rise and concerns associated with burning the fuels increase, electric vehicle sales continue to grow. According to the U.S. Department of Energy, EV sales “tripled from about 17,000 in 2011 to about 52,000 in 2012” [1]. In order to meet consumer transportation expectations—molded by fuel-powered vehicles—electric cars must have the ability to “refuel” quickly. Rapidly charging an EV’s traction battery poses one solution but doing so requires large power levels “five times as much as the average office consumes,” [2] making rapid charging less than ideal for the masses. Alternatively, swapping an EV’s depleted battery with a charged one eliminates the vehicle’s charging downtime and allows the battery pack to charge at an optimal rate while out of the vehicle.
