Power System Testing and Verification for a Space Camera System With 18650 Batteries
Abstract
CubeSat functionality is often limited by not only volume but also power. As such, there have been multiple advances in devices to store energy with higher energy density. 18650 Lithium-Ion Cells are a common battery used for low current draw use cases, making them an economical and approachable candidate as primary batteries for powering this type of small spacecraft. However, it is known that the performance and efficiency will vary according to different environmental conditions, in particular, temperature–requiring thorough testing of the batteries at extreme conditions. This paper will explore environmental tests to verify a power system based on 18650 batteries for a mission duration and to rate them for human spaceflight. The main tests that were conducted included discharge tests at various temperatures and cyclic testing corresponding to the environment in which the batteries will be used. From this performance, data is collected on the battery’s performance at a range of temperatures, discharge rates, and environmental conditions, validating the battery for space applications.
