Abstract

Disclosed herein is a service center and method designed to promote the use of a battery-powered, electric vehicle which allows a discharged battery to be easily and quickly replaced in the electric vehicle and then recharged for use in another electric vehicle. The service center and method uses a plurality of universally-adaptable batteries capable of being used in most, if not all, battery-powered, electric vehicles. The batteries are designed to be lifted into or lowered from a battery receiving space formed on the bottom of an electric vehicle. During use, the electric vehicles are driven into a service center. The batteries are unlocked from the vehicle and then conveniently removed and transported to a recharging unit located in the nearby recharging center. A second, recharged battery is then removed from the recharging unit and transported to the electric vehicle. The second battery is then installed and locked in position in the electric vehicle. By using the service center and method, the heavy electric battery is easily handled and the lengthy waiting time for recharging the battery is eliminated, thus making it possible to travel unlimited distances in the electric vehicle.

Claims

1. A service center for replacing and recharging an electric batteries from electric vehicles, comprising:

a. at least one recharging unit capable of recharging a battery removed from an electric vehicle;

b. a removal-installation means capable of removing and installing the battery from an electric vehicle, said removal-installation means being a pivoting lifting platform; and

,

c. a transporting means capable of transporting a discharged battery from said removal-installation means to said recharging unit, said transporting means also capable of transporting a recharged battery from said recharging unit to said removal-installation means for installation into an electric vehicle.

2. A service center, as recited in claim 1, further including at least one bay upon which an electric vehicle may be driven, said bay including a lower pit in which said removal-installation means and said transporting means are located.

3. A service center, as recited in claim 2, further including said recharging unit being located inside a recharging center and providing access to said recharging unit.

4. A service center, as recited in claim 2, further including a second lifting means disposed between said transporting means and said recharging unit capable of moving a battery between said transporting means and said recharging unit.

5. A service center, as recited in claim 4, wherein said second lifting means is a rack with a plurality of vertically adjustable shelves attached thereto, capable of receiving a battery to be recharged by said recharging unit.

6. A service center, as recited in claim 2, wherein said second lifting means is an end lifting platform.

7. A service center, as recited in claim 6, wherein said end lifting platform rotates around a vertical aligned center member.

8. A service center, as recited in claim 6, further including a vertically aligned rack with a plurality of tilting shelves attached thereto, each said tilting shelf having means for receiving and holding a battery from said end lifting platform.

9. A service center, as recited in claim 1, wherein said removal-installation means is a conveyor lifting platform.

10. A service center, as recited in claim 9, wherein said transporting means is an elongated conveyor.

11. A service center, as recited in claim 1, wherein said transporting means is an elongated rolling platform.

12. A service center, as recited in claim 11, wherein said elongated rolling platform pivots around an off-set axis, said axis being located so that the end closest to said pivoting lifting platform is slanted.

13. A service center, as recited in claim 11, further including said elongated rolling platform having an opening upon which said pivoting lifting platform may engage.
