摘　　要：卫星电源系统多采用锂离子蓄电池作为储能装置,结合锂电池的特性研究了锂电池充电控制方式,对传统GEO卫星用锂离子电池的充电控制方式和基于下一代电源控制器的新型充电控制方式进行了对比分析。通过波形表明,传统锂电池充电控制方式,在继承氢镍电池充电控制器的基础上,依照锂离子蓄电池的特性对充电控制方法进行了改进,可满足锂离子蓄电池组的充电要求;新型的锂电池充电控制方式可有效对锂离子电池进行自主恒流恒压充电,有助于延长电池使用寿命,且易于实现对电池的保护,更适合GEO卫星锂离子蓄电池组的充电需求。Lithium ion battery is often used as energy storage device in satellite power system. According to the characteristics of the lithium ion battery, the charging control mode of traditional GEO lithium ion was introduced, and the new charging control mode based on the next generation power conditioning unit was studied and compared with the traditional one. The waveforms show that traditional charging control method, inheriting nickel-hydrogen battery charging controller, has improved the control method and can meet the requirement in satellite. The new charging control mode can effectively charge the lithium ion battery at constant current and constant voltage, which is helpful to extend battery life, and easy to realize the battery protection, which is more suitable for the charge demand of GEO satellite lithium ion battery.
