摘要
由于锂离子蓄电池具有比能量高的突出优势,地球同步轨道(GEO)卫星的空间储能设备已由氢镍蓄电池替代为锂离子蓄电池。上一代卫星采用60~100 Ah锂电池组作为储能设备,实现了锂电池组首次在我国GEO轨道通信卫星上的应用。最新一代卫星采用150~250 Ah大容量、高比能量锂电池组首飞成功,象征着我国大容量、高比能量锂电池组的成熟应用。随着大容量、高比能量锂离子蓄电池的广泛应用,充电控制方式和均衡方式相应进步,针对锂电池组的在轨管理策略也有相应的变化,阐述了两代卫星锂电池组在轨管理策略。
Due to the outstanding advantage of lithium-ion battery with high energy density,the space energy storage devices of GEO satellites have been replaced by lithium-ion batteries from nickelhydrogen batteries.The last generation of satellites used 60-100 Ah lithium-ion battery as energy storage devices,which realized the first application of lithium-ion battery in Chinese GEO communication satellites in orbit.The latest generation of satellites uses 150-250 Ah lithium-ion battery in orbit,symbolizing the mature application of lithium-ion battery with high capacity and energy density.With the wide application of large capacity and high energy density lithium-ion battery,the charging control and balance techniques have been improved accordingly,so the on-orbit management strategy of lithium-ion battery has also changed correspondingly.The on-orbit management strategies of lithium battery packs for two generations of satellites were described.
