Abstract
A battery-powered vehicle has two batteries which are replaced, rather than recharged in the vehicle. The vehicle is powered by only one battery at a time and that battery is used until substantially all of the energy the battery is exhausted. A discharged battery is replaced while the vehicle operates with the other, nondischarged battery. Preferred batteries have high energy density and may be of a type that is not rechargeable. An example is an aluminum-air battery. The non-rechargeable discharged batteries can be remanufactured to produce new batteries for further use in the vehicle.
