METHOD TO OPERATE NICKEL-HYDROGEN ACCUMULATOR BATTERIES OF SPACECRAFT POWER SUPPLY SYSTEM (VERSIONS) Russian patent published in 2013 - IPC H01M10/44 H01J7/02 

FIELD: electricity.

SUBSTANCE: invention may be used in operation of nickel-hydrogen accumulator batteries (AB) in autonomous power supply systems (PSS) of spacecrafts (SC), functioning on a low circumferrestrial orbit. In case of abnormal operation of a charging-discharging device related to a failure of only a charging device, or only a discharging device or a charging-discharging device in general. For performance of a forming cycle of AB, an emergency bus is used with switching equipment controlled by one-off commands from a surface complex of control, at the same time in the first version of the failure the charge of the formed AB is carried out by means of its connection to any charging device of the operable charging-discharging device, which forms a subsystem with the "internal" AB, in the second version of the failure the formed AB is discharged by the discharging device of any operable charging-discharging device, which creates the subsystem with the "internal" AB, in the third version of the failure the formed AB is discharged and charged, using the charging and discharging devices of any operable charging and discharging device, creating the subsystem with the "internal" AB.

EFFECT: increased reliability of operation of a nickel-hydrogen accumulator battery and vitality of an SC as a whole.
