Abstract

The invention discloses an automatic management system for a lithium ion storage battery pack power supply sub system for a satellite. The automatic management system comprises an in-orbit management module, an emergency protection module and a lithium ion storage battery pack in-orbit different stage management mode method; the in-orbit management module is used for preventing the lithium ion storage battery pack from being over-charged; the emergency protection module is used for preventing the lithium ion storage battery pack from being over-discharged; and the use and management mode method for the lithium ion storage battery pack in-orbit different stages is used for prolonging the in-orbit running service life of the lithium ion storage battery pack. The in-orbit management and control for the satellite lithium ion storage battery pack power supply sub system is realized, so that the reliability of the system is greatly improved fundamentally.

Description

technical field [0001] The invention relates to the technical field of spacecraft power supply subsystem design, in particular to an autonomous management system of the satellite lithium-ion battery pack power supply subsystem. Background technique [0002] The satellite power subsystem usually adopts a solar array-battery system and an adjustable DC bus system power supply scheme. During the service life, the power subsystem completes uninterrupted power supply to the loads of each subsystem on the satellite, including long-term power and short-term power. During the light period, the energy collection of the solar cell array is completed, and the solar energy is converted into electric energy, which supplies power to the load and charges the battery pack. During the shadow period, the battery supplies power to the bus through the discharge regulator or when the load power exceeds the power supply capacity of the solar cell array during the light period. , powered by batter...
