Abstract
Abstract A battery charging system for battery-powered vehicles has a battery transfer station, at which a vehicle is positioned for removal and replacement of the spent and charged battery. The spent battery is removed from the vehicle and transferred to a charging system, and a charged battery is transferred from the charging system to the vehicle. In one form, the batteries are conveyed through a continuous charging system, upon removal from the vehicle, and a fully charged battery is deposited in the vehicle. In another form, batteries are transferred from and to the vehicle by a battery transfer system which transfers the batteries to and from storage and charging bays. In all cases, the discharged battery is removed from the vehicle, and a charged battery is installed in the vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A battery charging system for electric vehicles comprising: a battery transfer station for receiving a vehicle; means operable at said transfer station to remove a spent battery from the vehicle and for installing a charged battery in said vehicle, means providing a plurality of charging stations; in a continuous path from and to said transfer station and means for moving spent batteries from said battery transfer station through said charging stations and returning charged batteries to said transfer stations; including an endless conveyor connectable to said batteries, and extending along said path, said charging stations being spaced along the path of said endless conveyor, said conveyor having means to engage and transport the batteries through said path.
