METHOD OF NICKEL-HYDROGEN ACCUMULATOR BATTERY OPERATION IN INDEPENDENT POWER SUPPLY SYSTEM OF SPACECRAFT AND INDEPENDENT POWER SUPPLY SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC H01M10/00 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering and may be used at making nickel-hydrogen accumulator batteries and independent power supply systems of space vehicles (SV). The assigned task is solved by the suggestion of the operational method of the nickel-hydrogen accumulator battery in an independent power supply system of space vehicles, which lies in the performance of its charges and storage in the charged state with periodical additional charges, performance of discharges and thermal conditioning for cylindrical surfaces of the batteries by means of a cold plate coupled thermally with them, thermal conditioning for cylindrical surfaces of the batteries by means of a cold plate not coupled thermally with them in order to increase their current temperature and by the suggestion of the independent power supply system of a space vehicle to implement the method; at that the above system comprises a solar battery connected to the load through a voltage converter, accumulator batteries, charge and discharge converters, an accumulator battery control unit and load of the battery hemispheres by electric heaters based on their current charge and discharge voltage values; at that thermal conditioning for cylindrical surfaces of the batteries by means of a cold plate not coupled thermally with them is made for the batteries having high charge voltage or low discharge voltage, and in the independent power supply system of the space vehicle there is an additional current stabiliser connected by its input to input or output busbars of the independent power supply system and by its output to the electric heaters coupled into a series circuit, in what connection each eclectic heater in the initial state is shunted by controlled switches related to control devices of the accumulator batteries.

EFFECT: improvement of operational reliability of nickel-hydrogen accumulator battery for the space vehicle.
