摘　　要：锂离子蓄电池组作为GEO卫星的储能电源,已经得到广泛应用。为了防止锂离子蓄电池组在长期充放电过程中离散性的扩大,运行在GEO轨道的长寿命卫星用锂离子蓄电池组一般设计有均衡管理功能,目前在轨广泛应用的一般均为耗散型均衡。根据均衡启控方式不同,可分为定时均衡、定电压均衡和控制电压差均衡三种均衡方式。通过对GEO卫星锂离子蓄电池组典型的三种在轨耗散型均衡方式的遥测数据进行分析,论述了目前在轨应用的这三种均衡方式的均衡特点和在轨均衡效果。Lithium ion batteries have been widely used as the energy storage power source of the satellite.In order to prevent the battery from expanding in the long term charging and discharging process,the long life satellite in orbit is designed with a balanced management function.At present,the dissipative equilibrium is widely used in orbit,which can be divided into three types:timing equilibrium,constant voltage equilibrium,and voltage difference equilibrium.Based on the analysis of typical three balancing types telemetry data of lithium ion batteries,this paper discusses equilibriumcharacteristics and the effect of three kinds of equilibriummodes in the current in orbit application.
