Design and Implementation of GEO Battery Autonomous Management System for Lithium Battery with Balanced Control Function

Abstract

To solve the problem of autonomous management of lithium batteries with balanced control energy in GEO satellite, this paper analyzes the requirements of the main management of lithium batteries, and presents the design scheme of the software system for the autonomous management of lithium batteries, which includes charge and discharge management of lithium batteries, mode conversion, Autonomous balanced management; self-overvoltage, over-temperature and over-current charging protection of the software, and bus overvoltage protection. The design and implementation of the system is verified on a GEO satellite. The design and implementation of the autonomous management software system proposed in this paper can provide reference for the autonomous management of lithium batteries with balanced control function for the follow-up GEO satellites.
