METHOD OF NICKEL-HYDROGEN ACCUMULATOR BATTERIES OPERATION IN POWER SUPPLY SYSTEM OF SPACECRAFT WITH LARGE SERVICE LIFE Russian patent published in 2017 - IPC H01M10/44 B64G1/00 

FIELD: electrical engineering.

SUBSTANCE: use: electrical engineering during nickel-hydrogen storage batteries (SB) operation in spacecrafts (SC) autonomous power supply systems (PSS), operating at low earth orbit. According to method in case of standard onboard telemetric information system (OTIS) transmitter failure due to any of technical reasons for PSS state monitoring, including and formed SB, using information of control and operating sub-arrays of operative control information (OCI) array, generated and displayed in it by initial data, issued by OTIS to on-board control system. At that, during performance of formed SB discharge mode establishing, at least, three communication sessions with SC with removal of OCI during each communication session. Said sub-arrays, composed of analogue and signal SB parameters, are divided into separate data groups, differing from each other by combination of SB parameters, wherein one of sub-arrays groups of SB parameters, representing control and telemetric information, are generated and displayed in OCI array upon activation of either any of n SB signal pressure sensors, or by fact of any SB minimum voltage threshold sensors triggering or any storage battery minimum voltage. Other sub-array groups of SB parameters, which are operating telemetric information, are generated and displayed in OCI array in defined time sequence, wherein number of groups of SB parameters and time intervals between them are set within operating program (OP). Rate of formed SB discharge is calculated, using OCI array data, at least, from two communication sessions with SC, and according to known SB rate of discharge determining design number of orbit turn N for forced cancellation of formed SB deep discharge mode. Single commands (SCS), required for actual completion of formed SB discharge mode, are issued in communication session on turn (N+1) or (N+2), wherein in communication sessions, in which are SCS are issued by formed SB operation control modes or change in PSS configuration using emergency busbar switching equipment, performing second OCI removal. At that, parameters of SB, displayed within OCI correspond to SCS issuing moment of time for second OCI removal.

EFFECT: technical result is increase in SB charging/discharging control efficiency.
