SPACECRAFT Russian patent published in 2014 - IPC B64G1/42 B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to electric power supply and thermal control systems of spacecraft. Spacecraft thermal control system comprises instruments for heat bleed, feed and discharge. Spacecraft power supply system comprises solar battery, voltage automatic control and stabilisation complex, storage batteries and their control devices. Spacecraft incorporates also onboard control complex with onboard computer. Note here that storage battery control devices are incorporated with data exchange channel between said voltage automatic control and stabilisation complex and onboard computer. The latter is equipped with the program for spacecraft load current control and storage battery discharge current redistribution. Discharge current of every storage battery is set by spacecraft load current, storage battery current capacity and total capacity of storage batteries with due allowance for difference in load voltage and mean discharge voltage of storage batteries. Additionally, onboard computer can be equipped with program for control over excess power of solar battery and over charge current of every storage battery. Note here that said currents are computed from excess power, mean charge current and current and total capacities of said storage batteries.

EFFECT: higher efficiency, perfected operating condition of power supply system.
