METHOD FOR SERVICING NICKEL-HYDROGEN STORAGE BATTERY INCORPORATED IN ARTIFICIAL EARTH SATELLITE Russian patent published in 2008 - IPC H01M10/44 H01M12/06 

FIELD: electrical engineering; off-line power systems.

SUBSTANCE: proposed method for servicing nickel-hydrogen storage battery incorporated in artificial Earth satellite includes battery charge and discharge, its storage in charged condition, periodic charge with pulse current, and its periodic check-up for condition. Charging battery with pulse current involves alternation of charge and discharge pulses, magnitude of charge pulse being set to equal that of rated charge current; mean value of charge pulses is set according to following expression: (I_ch.RNS + 3I_s-d)/η_ch > I_ch._RMS > (I_d.RNS + I_s-d)/η_ch, where I_ch.RNS is RMS value of charge pulses; I_d.RNS is RMS value of discharge pulses; I_s-d is maximal self-discharge current of battery; η_ch is efficiency with respect to charge current corresponding to I_s-d.

EFFECT: enhanced effectiveness of eliminating unbalance in battery capacity which enhances its backup capacity and operating reliability.
