Hardware-in-the-Loop (HIL) Test of Lithium-Ion Battery Module For Small Satellite

In a space mission, a satellite must maintain a power supply until it reaches End-Of-Life (EOL). To ensure mission continuity, it is crucial to test battery modules and perform qualification and integration tests to ensure that the specified power budget is met. This process is applicable to all types of orbits, including Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Earth Orbit (GEO), Geosynchronous Transfer Orbit (GTO), and Sun-Synchronous Orbit (SSO). The development of an Electronic Power System (EPS) requires qualification and validation stages before selecting the modules to be integrated into the satellite system. In this study, we propose a solution to address the testing needs for energy storage modules in small satellites. We have developed a testing simulator system or Hardware-In-the-Loop (HIL) that approximates orbital operational conditions. This system comprises a hardware and software platform that allows pre-selected Lithium-ion (Li-ion) battery cells for space missions to experience conditions similar to those in orbit. This is achieved through a charging and discharging cycle that can be continuously repeated until the end of the satellite's lifespan. This research facilitates battery testing in a specific environment with controlled temperatures for satellite missions and performs endurance testing and characterization of Li-ion cells to ensure their suitability for use in satellite systems.
