METHOD OF CONTROLLING AUTONOMOUS POWER SUPPLY SYSTEM OF SPACECRAFT Russian patent published in 2017 - IPC H02J7/34 

FIELD: electricity.

SUBSTANCE: in the autonomous power supply system (PSS) with the AB, made on the basis of nickel metal hydride (NMH) batteries, control the entered single control device permanently all NMHs AB without switching them off; determining the optimum recharge factor AB in relation to the response signals of the pressure sensors (PS) in the AB for a specified number of cycles on the commands of the on-board computer system (OCS) of the spacecraft (SC). Prohibit and allow the operation of charge controllers depending on the temperature difference between the temperature of one of the batteries and the temperature of the base of the battery. To eliminate the accumulating error in the indication of the actual capacity AB prohibit the operation of the charge regulators on the signals of the ampere-hour counter in the absence of signals of PS triggering in AB for a specified number of cycles by the commands of the airborne engine. Prohibit the operation of the charge regulators when receiving signals about exceeding the preset pressure from the PS.

EFFECT: increasing the reliability of the power supply system, ensuring the survivability and long-term operation of the spacecraft.
