  • Publication number: 20080053716
    Abstract: The electrical vehicle energy storage system permits the electric refueling of the electric vehicle just like an automobile would be refueled with gasoline at a gas station. Circuitry on board the vehicle accessible by the electric refueling station enables the determination of the energy content of the battery module or modules returned to the electric refueling station and the owner of the vehicle is given credit for the energy remaining in the battery module or modules which have been exchanged. Selective refueling may take place for given battery modules by removing them from the battery system and charging them at home, office or factory. A process for operating an electric vehicle is also disclosed and claimed.

  • Publication number: 20070188137
    Abstract: A scalable intelligent power-supply system and method capable of powering a defined load for a specified period of time is disclosed and claimed. Multiple external AC and DC inputs supply power to the system if available and required. An internal DC input from a back-up energy source is on board. The back-up energy source is scalable by adding additional energy cartridges such as batteries in racks mounted within frames of the system. The AC and DC inputs (including the internal DC input) are controlled, measured, sensed, and converted by circuitry controlled by the microprocessor into multiple AC and/or DC outputs. A microprocessor manages power input to, within, and output from the system. The performance of a Lithium-ion batteries used to power an automobile can be determined on the basis individual battery packs or individual battery cells within the packs.

  • Patent number: 4167462
    Abstract: An improved apparatus for electrolytically removing material from a workpiece includes a plurality of electrodes which are movable relative to each other through working strokes. In order to coordinate the movement of the electrodes, they are stopped at one or more predetermined intermediate positions during their working strokes. When all of the electrodes have arrived at intermediate positions, the electrodes are simultaneously moved away from their intermediate positions toward their end of stroke positions. In order to accommodate variations in the rate at which material is electrolytically removed from a workpiece, the speed of movement of the electrodes and/or the electrical potential established between the electrodes and the workpiece can be varied. Relatively large diameter rams connected with the electrodes are supplied with fluid from relatively small diameter piston and cylinder type pumps.
