Autonomous diagnosis method for discharge final voltage of hydrogen-nickel storage battery for satellites

The invention discloses an autonomous diagnosis method for the discharge final voltage of a hydrogen-nickel storage battery for satellites, and belongs to the technical field of satellite batteries. The invention aims to solve the contradiction between the long-life on-orbit use requirement of a storage battery and the determination of the on-orbit charging management strategy adjustment time of the storage battery, and proposes a simplified prediction model for the discharge final voltage of the hydrogen-nickel storage battery on the basis that the influence factors such as discharge depth, temperature, overcharge quantity, overcharge rate, service life and battery storage loss are fully analyzed, so the on-orbit maintenance of the storage battery can be carried out by more accurately andreasonably selecting the opportunity, the on-orbit service life of the hydrogen-nickel storage battery is prolonged, and meanwhile, the risk of under-voltage use of the on-orbit storage battery is greatly reduced.
