Abstract

This paper intends to report and describe a variety of activities such as modeling, simulation, design, implementation, test and analysis in order to design and develop EMUBAT, a battery emulator for space applications. The first step of EMUBAT development is battery modeling which is performed by using a typical equivalent circuit. The required parameters for battery modeling are extracted by means of electrical characteristics curves which are presented in battery datasheets or obtained from battery testing. Then, the orbit parameter modeling is investigated for LEO and GEO satellites. Battery thermal conditions due to its in-orbit operations are modeled in the next step. Finally, the hardware configuration and the software structure of EMUBAT are described. Besides, a battery test setup is presented, which is established to facilitate the process of obtaining the required data and parameters, for EMUBAT modeling and simulation. This test setup also makes it possible to have an easier and more precise verification of the emulator outputs.

通过设计开发空间电池仿真器，提高了电源子系统的EGSE

本文旨在报告和描述为设计和开发用于空间应用的电池模拟器EMUBAT而进行的建模、仿真、设计、实现、测试和分析等各种活动。EMUBAT开发的第一步是电池建模，这是通过一个典型的等效电路来完成的。电池建模所需的参数是通过电池数据手册或电池测试获得的电特性曲线来提取的。然后，对LEO和GEO卫星的轨道参数建模进行了研究。下一步将对电池在轨运行时的热条件进行建模。最后，介绍了EMUBAT的硬件配置和软件结构。此外，为了便于EMUBAT建模和仿真所需数据和参数的获取，还建立了电池测试装置。该测试设置还可以更容易和更精确地验证仿真器输出。
