Research Progress on Thermal Runaway Protection of Lithium-Ion Power Battery

Abstract

The attention of electric vehicle (EV) development is still hot at present. As an important part of EV - power battery, its safety issue still maintains great attention. In recent years, the research on thermal runaway (TR) of lithium-ion batteries (LIBs) has taken a big step forward. The latest research on TR mechanism, inducement and propagation are firstly introduced, and the latest research status of TR protection is partially extended in combination with these principles. Then the influence of the material and design of the battery cell components on TR is introduced, and lastly the safety measures before and after TR are comprehensively reviewed. This paper has a summary effect on past TR research and a referential effect for future TR protection.

Design of real-time monitoring system for battery voltage characteristics based on LabVIEW

“…Among all the external environmental factors that affect the battery characteristics, the change of temperature directly affects the charging and discharging efficiency, charging and discharging time, internal resistance and other characteristics of the battery. Therefore, temperature is one of the most important factors that affect the battery characteristics [1]. The battery characteristics at different temperatures have also become the most important reference index for battery selection.…”
