  • Lithium polymer battery charger methods and apparatus
    Patent number: 5773959
    Abstract: Lithium polymer battery charger methods for charging a plurality of equal charge point lithium polymer battery cells prevent overcharging of any cell, whether the cells are arranged in a series stack or are arranged in parallel. When the cells are connected in a series stack, a power supply is connected to the series stack to apply a charge current to the series stack. The state of charge of each cell in the stack is monitored. Information that the state of charge of any cell is approaching full charge is used to control the charge current and to prevent overcharging of any cell.
    Type: Grant
    Filed: January 11, 1996
    Date of Patent: June 30, 1998
    Assignee: Lockheed Martin Corporation
    Inventors: Lauren V. Merritt, Vincent L. Teofilo, Roger Paul Hollandsworth, Zaid B. Rodriguez, Jack G. Lovgren
