摘　　要：在东方红四号卫星平台上应用锂离子电池替代传统氢镍电池,能显著减小供配电分系统的质量和体积,提高卫星平台能力。锂离子电池工作特性与氢镍电池差异较大,针对锂离子电池在东方红四号平台某卫星上首次应用,为降低应用风险,满足在轨使用要求,文章对电池热控设计、电源在轨充放电管理和均衡策略进行分析,利用SLIM(SAFT Li-ion Model)软件对锂离子电池在轨电压输出特性进行仿真,提出适应锂离子电池应用的热控措施、充放电管理方式和线性均衡管理策略,并利用某卫星在轨数据进行验证,满足了在轨使用要求,证明该锂离子电池应用方案可以在后续东方红四号卫星平台推广应用。The application of lithium-ion battery on DFH-4 platform will reduce the electrical power subsystem mass and volume, enhance platform capability and increase economy. Lithium- ion battery have different performances from Ni-H2 battery. In order to reduce the application risk, the article analyzes the temperature control method, charge and discharge management and balance strategy. The article introduces the application solution of lithium-ion batteries applied on DFH-4 platform. By using in-orbit telemetry, this article analyzes battery management results, battery flight performance,temperature characteristics, cell-voltage consistency and balance function. The results can be as reference for the follow-on DFH-4 platform.
