OPERATING PROCESS OF NICKEL-HYDROGEN STORAGE BATTERY INCORPORATED IN GEOSTATIONARY ARTIFICIAL EARTH SATELLITE Russian patent published in 2007 - IPC H01M10/42 H02J7/02 

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

SUBSTANCE: proposed nickel-hydrogen storage battery operating process involves checkup of steady-state self-discharge current and degree of battery charge against analog pressure transducers, battery storage in charged state with periodic additional charges to compensate for battery self-discharge in solar orbits, and conduction of charge-discharge cycles in shadow orbits; steady-state self-discharge current is maintained in battery between 0.003 and 0.006 of its rated capacity; additional charge is ceased according to arithmetic mean of analog pressure transducer readings whose value affords desired steady-state self-discharge current during additional charge ranging between 0.01 and 0.012 of battery rated capacity under charge-discharge cycle conditions. In addition battery location temperature is checked, and battery self-discharge steady-state current is maintained between 0.003 and 0.006 of rated capacity at battery location temperature below 10-12 °C both in additional-charge mode and during charge-discharge cycles; additional impulse charge is conducted, its parameters (period and relative pulse duration) being chosen to provide for mean charge current higher in magnitude by two or three times than battery steady-state self-discharge current.

EFFECT: enhanced use factor and operating reliability of battery.
