摘　　要：介绍了目前我国航天器上电源系统中充电控制的几种主要方式,较为详细地描述了其控制原理及工作方式。在对当代空间电源系统中蓄电池充电控制技术总结和分析的基础上,结合航天器电源系统未来的发展趋势,研究并提出了一种利用晶体管pn结的温度特性作为温度传感器取代传统热敏电阻的V-T曲线充电控制的新方法,并对其相关的原理和设计进行了详细的阐述,从而为满足现代以及今后航天器的长寿命和高可靠性的要求而进行的空间电源系统设计和研制提供了一种行之有效的方法和途径。This paper mainly researches about several charging control technologies of space power in China spacecraft, and giving a more detailed description of its controlling principle. On the basis of the summarization and analysis of battery charging control technology in contemporary space power system,combining the development of future aerocraft power system, a new way of charging control is researched and presented by using temperature characteristics of transistor pn junction＇s as the temperature sensor instead of using traditional thermistors＇ V-T curve characteristics. Also the designing and working principle of the new charging control is detailedly explained, as well as it provides an effective method and means for the research and designs of long-life and high-reliability space power system.
