ACCUMULATOR STORAGE BATTERY OF SPACE VEHICLE Russian patent published in 2015 - IPC H01M10/00 

FIELD: electricity.

SUBSTANCE: invention is related to the electric engineering industry and may be used for the development and further operation of accumulators and accumulator batteries of different types in independent power supply systems of space vehicles, in particular of artificial Earth satellites (AES). The technical result consists in the reduced mismatch of capacity for separate accumulators. The set task is solved by the design of the AES accumulator battery consisting of n in-series accumulators and heat-transfer devices of a heat pipe type and incorporation of an evaporating section of heat-transfer devices into central areas of accumulator electrode units and heat contact of capacitors of the heat-transfer devices with cases of the accumulators. The claimed design of the accumulator battery for AES allows the reduction of temperature difference inside the accumulator (so called temperature gradient) thus leading to the reduced mismatch in capacity of individual accumulators.

EFFECT: increased permitted safe cycling depth, which is equal to the decreased degradation of the battery specific energy.
