摘　　要：在以往航天器研制过程中,电源系统能量平衡分析是基于表格化计算的方法,其运算效率低、显示不直观。文章提出了一种可视性强、易编程、更通用的能量平衡分析方法,即采用嵌入式MATLAB函数对电源系统能量平衡分析的功能模块进行编程实现,以火星车电源系统为应用背景,在MATLAB/SIMULINK平台上搭建了一套用于能量平衡分析的仿真系统,并在特定实例下进行仿真分析,仿真结果采用图表曲线形式显示,能清晰、直观地反映能源利用的动态变化趋势,可为电源系统方案优化设计提供参考依据。The energy system balance analysis is generally performed by table-calculation, which is not efficient and intuitive. This paper proposes a universal energy balance analysis method, which is visualized and easy to program, to replace the table-calculation method. The embedded MATLAB functions are used to program and implement the main function modules of the energy balance analysis. Based on the background of Mars rover EPS（electrical power system）, the simulation system is built in MATLAB/SIMULINK and specific simulations are performed. The output figures and curves clearly show the dynamic trends of the energy utilization, which can help to decide and optimize the EPS design.
