  • Patent number: 5760569
    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.

  • Patent number: 5711648
    Abstract: A battery transfer and charging system for electric vehicles includes a conveyor loop for conveying batteries from a battery receiving station to a battery delivery station. A displacement assembly removes spent batteries of electric vehicles by forcing charged batteries into position within the vehicles so as to laterally displace spent batteries. Spent batteries displaced from vehicles are received by the receiving station, where the batteries are tested both electrically and by comparing battery status data against predetermined criteria. Batteries which fail the battery test are automatically removed from the conveyor loop by a elevator assembly. Batteries are automatically charged as they pass through the conveyor loop in an assembly-line fashion. Following recharge, batteries are conveyed to the displacement station for installation within later vehicles.

  • Patent number: 5668460
    Abstract: A turntable is provided for use in recharging batteries of the type used in battery powered forklift trucks and the like. The turntable includes a peripheral array of charging stations each including a support platform and a battery charger for connection to and recharging of a battery on the platform. The turntable is rotatably driven in a stepwise manner to index the charging stations in succession to a transfer position. A push-pull ram at the transfer position draws a depleted battery from a forklift truck onto the platform of an empty charging station. The turntable is then indexed to move a recharged battery to the transfer position, and the push-pull ram installs the recharged battery on the forklift truck.

  • Patent number: 5612606
    Abstract: An integrated electric vehicle service station system for managing the exchange of heavy and bulky battery assemblies in electric vehicles. The battery exchange system includes a battery platform for supporting an assembly of batteries for the vehicle, a vehicle platform support structure within an electric vehicle for receiving and supporting the battery platform, and a mechanized vehicle service station facility for exchanging recharged battery platforms with spent platforms mounted on-board electric vehicles. The battery platform is of a simple modular shape that may be used with the large variety of sizes and shapes of electric vehicles that may be expected in the future. The battery platform support structure is a correspondingly simple structure that may readily be included in electric vehicles of widely differing designs.

  • Patent number: 5598083
    Abstract: A battery changing system is provided for an electrically powered vehicle. The battery changing system includes a housing for the battery. The housing includes first and second spaced crossbars. A battery manipulating mechanism is mounted to the vehicle. This battery manipulating mechanism includes at least one outwardly projecting arm that is pivotally connected to the vehicle and driven by an actuator so as to raise and lower the battery. More specifically, the arm includes an upwardly directed recess for engaging the first crossbar on the battery housing and a downwardly directed saddle for receiving the second crossbar of the battery housing. A locking plate may be selectively extended to secure the second crossbar in the saddle.

  • Patent number: 5549443
    Abstract: A battery transfer and charging system for electric vehicles. A displacement station removes spent batteries of electric vehicles by forcing charged batteries into position within the vehicles so as to laterally displace spent batteries. Spent batteries displaced from vehicles are received by a receiving station of the system. The receiving system includes an engagement device for engaging with engagement structures of the batteries, in order to assist the removal of spent batteries. Spent batteries removed from vehicles are tested and charged as they progress through the system in an assembly-line fashion. Following recharge, batteries are conveyed to the displacement station for installation within later vehicles. Batteries which cannot adequately be recharged are automatically removed from the system. In one embodiment of the system, vehicles drive through the system in sequential order, stopping at a specified location for battery installation/removal.

  • Patent number: 5542488
    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 in the battery is exhausted. A discharged battery is replaced while the vehicle operates with the other, non-discharged 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.

  • Patent number: 5508597
    Abstract: An apparatus for storing and changing battery packs from a battery powered vehicle. The battery powered vehicle drives toward a light source which aligns the battery powered vehicle with the apparatus. The apparatus is moved in a horizontal plane to a position underneath a battery holding location on the battery powered vehicle. An operator moves pneumatic carrier to a position directly underneath a battery pack located in the battery holding location. The apparatus is then moved in a vertical plane so that the pneumatic carrier engages a bottom section of the battery pack. The pneumatic carrier is then activated thereby lifting the battery pack on a cushion of air. This allows the operator to move the battery pack out of the battery holding location, across a platform deck of the apparatus, and to a storage location. The operator can then use the pneumatic carrier to move a fresh battery pack located in a different storage location to the battery powered vehicle.
