METHOD FOR SERVICING NICKEL-HYDROGEN STORAGE BATTERY IN OFF-LINE POWER SUPPLY SYSTEM Russian patent published in 2006 - IPC H01M10/44 H01M10/34 

FIELD: electrical engineering; off-line power supply systems for geostationary artificial earth satellites.

SUBSTANCE: proposed method for servicing nickel-hydrogen storage battery in off-line power supply system includes battery charge-discharge cycles, bypassing of lower-capacity cells by means of bypass discharge diodes, voltage check across each cell, and trickle charge with low currents precluding explosion-hazard concentration of oxygen-hydrogen mixture. In the course of service polarity of separate cells of battery is reversed. In addition, polarity reversal capacity of cell first brought to minimal potential is checked from moment this voltage is attained till end of discharge; polarity-reversal capacity is calculated disregarding current through bypass discharge diodes and battery charge is started upon trickle charge with low currents at capacity being not lower than polarity-reversal value.

EFFECT: facilitated servicing of battery polarity of whose cells is periodically reversed.
