METHOD FOR OPERATION OF LITHIUM-ION ACCUMULATOR BATTERY IN AUTONOMOUS SYSTEM OF POWER SUPPLY OF ARTIFICIAL EARTH SATELLITE Russian patent published in 2011 - IPC H01M10/44 H01M10/525 

FIELD: electricity.

SUBSTANCE: invention may be used to develop and operate lithium-ion accumulator batteries in autonomous power supply systems of artificial Earth satellite (AES). According to invention, method to operate lithium-ion accumulator battery in autonomous system of AES power supply consists in conducting charges, storage in charged condition, recharging, if necessary, discharging, control of voltage of accumulators and periodical balancing of accumulators by voltage by selection of accumulator with least voltage, connection to remaining accumulators of individual discharge resistors, with subsequent disconnection of appropriate resistors as voltage at appropriate accumulators achieves level of voltage of initially selected accumulator, balancing of accumulators by voltage is carried out in process of charging (recharging) of accumulator battery, at the same time voltage of each balanced accumulator is compared to voltage of initially selected accumulator by current value of the latter.

EFFECT: increased specific power characteristics and reliability of operation of lithium-ion accumulator battery in autonomous system of AES power supply.
