METHOD TO CONTROL AUTONOMOUS SYSTEM OF SPACECRAFT POWER SUPPLY Russian patent published in 2016 - IPC H02J7/36 

FIELD: electricity.

SUBSTANCE: method consists in control of charge condition of accumulator batteries, control of charging and discharging devices depending on input and output voltage of the power supply system and charge level of accumulator batteries. Operation of the respective charging device is prohibited when limit charge level is reached for the certain accumulator battery; when charge level is decreased up to the certain value the prohibition is lifted. Operation of the respective discharging device is prohibited when minimum charge level is reached for the certain accumulator battery; when charge level is reached up to the certain value for this accumulator battery the prohibition is lifted. Control of charge condition for accumulator batteries and operation of charging devices is carried out using two independent circuits: hardware and software; at that software monitoring and control circuit is coupled to on-board PC and is the master circuit, while hardware monitoring and control circuit is used as a reserve one.

EFFECT: improved operational reliability at effective use of accumulator batteries.
