AI Technical Summary
Existing technologies make it difficult to effectively simulate the thermal state of space lithium-ion battery packs in a wide temperature range environment, resulting in performance degradation and safety risks in spacecraft and satellites.
A ground simulation device for the thermal state of a lithium-ion battery pack is used, including a wide-temperature-range space environment simulation component, a thermal insulation mechanism, a cold plate, and a constant-temperature circulator. The heat exchange is isolated by the thermal insulation mechanism, and the cold plate and thermal conductive sleeve are used to exchange heat with the lithium-ion battery simulator. The temperature is adjusted step by step to gradually simulate the temperature changes in the space environment and the temperature changes of the simulator material.
It has achieved accurate simulation of the wide temperature range of space lithium-ion battery packs on the ground, improved the safety, reliability and accuracy of the simulation, and saved time and economic costs.
