  • Apparatus and method for predicting battery capacity and fitness for service from a battery dynamic parameter and a recovery voltage differential
    Patent number: 7545146
    Abstract: A method and apparatus for testing a storage battery is provided in which a battery is measured to obtain a battery dynamic parameter value such as conductance. The battery is measured to obtain an open circuit voltage, a resistance and a recovery voltage differential. A condition of the battery is determined as a function of the measured battery dynamic parameter, the open circuit voltage and the recovery voltage differential.
    Type: Grant
    Filed: December 9, 2004
    Date of Patent: June 9, 2009
    Assignee: Midtronics, Inc.
    Inventors: James K. Klang, Krzysztof Jeziorczak
