METHOD FOR EQUALIZING CAPACITY OF NICKEL-HYDROGEN STORAGE BATTERY INCORPORATED IN SPACE VEHICLE

摘要

FIELD: electrical engineering; power supplies for off-line power consumers such as spacecraft. ^ SUBSTANCE: proposed method for equalizing battery capacity makes use of tight dependence between rate of self-discharge of nickel-hydrogen cells and temperature and is implemented by disconnecting battery and load, its heating and storage at temperature not over 50 °C for time sufficient for complete discharge of all cells, that is, for voltage drop below 0.5 V. Proposed method is characterized in that it wants no special measures for its implementing as it uses heaters incorporated in storage battery. ^ EFFECT: ability of equalizing capacity of all battery cells dispensing with extra charges for implementing this method. ^ 1 cl
