Abstract:

A system for "refueling" an electric vehicle includes a traction battery on a tray that is slidably disposed in a battery compartment of the vehicle and that is electrically connected to the traction motor of the vehicle. When the battery is depleted, the vehicle stops at an energy replenishment center which stores charged replacement traction batteries. The traction battery is electrically disengaged from the motor and the tray in the vehicle is slid out of the vehicle onto a dolly or into a receptacle of a carousel. Then, the replacement battery tray, which is disposed on another dolly or in another receptacle of the carousel, is juxtaposed with the battery compartment and slid into the compartment. Next, the fresh battery is electrically engaged with the motor, and the vehicle quickly resumes its journey. The depleted battery is recharged at the energy replenishment center and reused on a subsequent vehicle.
