摘　　要：锂电池电极结构特殊,在过充电、过放电和短路条件下使用均会影响电池寿命甚至造成安全危害,锂电池保护电路是确保其安全可靠使用的关键。针对空间便携设备用锂电池特有的使用环境,从过充电、过放电和短路三个方面提出了保护电路功能需求与具体的解决方案。Lithium-ion battery has a special electrode structure, when it uses under the conditions of overcharge, overdischarge or short circuit, it will be influence the service life even cause a security risk. So the protection circuit of lithium-ion battery is the key to ensuring its safe and reliable to use. In this paper, focusing on the special environment of lithium-ion battery used in space portable equipment, the functional requirements of protection circuit is proposed and the specific solutions are given fromthree aspects of overcharge, overdischarge and short circuit.
