METHOD OF OPERATION OF LITHIUM-ION ACCUMULATOR BATTERY IN AUTONOMOUS POWER SUPPLY SYSTEM OF EARTH SATELLITE VEHICLE Russian patent published in 2019 - IPC H01M10/44 H01M10/525 H02J7/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely, to a method for operating a lithium-ion battery in an autonomous power supply system, and can be used in autonomous power supply systems of an Earth satellite vehicle (ESV). Method includes carrying out charges, in a charged state of recharges, if necessary, discharges, control of battery voltage, disconnection of faulty batteries from a series of accumulator batteries, periodic battery voltage balancing, at the same time, the levels of the maximum and minimum voltage of the batteries are monitored, and if the battery's measured voltage is significantly exceeded, the maximum charge value, either when the measured battery voltage drops to zero or reverses the polarity, the faulty battery from the series circuit of the battery packs is disconnected immediately.

EFFECT: increasing the reliability of the operation of the lithium-ion battery in the autonomous system of power supply of the satellite with the sudden failure of any battery of the battery is a technical result of the invention.
