  • Battery system electrical connection apparatus and method
    Patent number: 6023146
    Abstract: Disclosed is a battery system in which a battery is provided with a pair of quick connect electrical contact mechanisms. A battery tray, for receiving the battery, is also provided with a pair of quick connect electrical contact mechanisms which are adapted to connect and establish electrical continuity with the battery quick connect mechanisms. The battery pin assemblies may be molded into the battery cover and may be welded to the existing positives and negative battery posts. In this manner, the provision of the pins requires no additional penetrations of the battery container, thus reducing the potential for leakage of electrolyte from the container. The pins may be nested within indentations provided in the container. In this manner, the provision of the pins adds only minimally to the overall dimensions of the battery, thus resulting in a compact design.

  • Mechanical and thermal improvements in metal hydride batteries, battery modules and battery packs
    Patent number: 5879831
    Abstract: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power.

  • Battery cover for prevention of electrolyte leakage
    Patent number: 9269931
    Abstract: In a battery cover, a sealed assembly structure of upper and lower covers of a battery case is configured in such a way that it forms a labyrinth structure that can allow an electrolyte to move upward and downward, thereby increasing an electrolyte leakage resistance of the battery case. Gas discharge holes and micro-holes are formed in the battery cover, and so the battery cover can easily discharge gas from the battery case. In the battery cover, electrolyte recovery ports are arrayed in such a way that the electrolyte can be prevented from leaking from the battery case even when the battery case is turned over or tilts to one side.
