METHOD OF OPERATING NICKEL-HYDROGEN STORAGE BATTERY INCORPORATED WITH UNTIGHT SPACECRAFT WITH RADIATION COOLING AND SPACECRAFT TO THIS EFFECT Russian patent published in 2009 - IPC B64G1/42 B64G1/50 H01M10/42 

FIELD: aerospace engineering.

SUBSTANCE: inventions relates to power supply of space vehicles, mainly geostationary satellites with three-axis orientation. Proposed method comprises charging/discharging storage batteries and storing them as charged. Analog pressure and temperature pickups local heaters are fitted on storage batteries. In operation, current heat emission is determined for it to be adjusted by local heaters proceeding from its thermal balance. In compliance with this invention, spacecraft comprises instrument unit representing rectangular parallelepiped. Inner surfaces of aforesaid unit accommodate devices and instruments, including thermal control system with local heaters. Thermal control system extracts heat to radiators. There is also onboard system of power supply with stabilised voltage converter. Analog pressure and temperatures pickups are connected, via storage battery control device, in data exchange channel between aforesaid voltage converter, thermal control system and onboard computer. The latter incorporates program designed to correct local heater operation depending upon charge degree, storage battery operating conditions and temperature.

EFFECT: higher efficiency, longer life.
