Thermal Runaway Warning Technology Based on Lithium-Ion Battery Temperature Lithium-ion batteries can experience thermal runaway, which is characterized directly by a significant rise in internal temperature and indirectly by a rise in surface temperature.
Lithium-ion battery 0.5 C overcharge test curve . In conclusion, voltage can be used as a warning parameter for thermal runaway, but because it is related to the nature of the battery body and changes there are caused by other conditions as well as thermal runaway, it is less frequently used as a separate warning parameter.
However, the concern about battery thermal runaway (TR) spreads due to multi-scale applications of both nickel‑cobalt‑manganese (NCM) ternary lithium-ion batteries and lithium‑iron-phosphate (LFP) batteries, which raises the necessity of identifying battery internal short circuit (ISC) and warning TR.
Enhancing the safety of lithium-ion batteries at the cell level (internal protection) and using cooling or barrier technologies throughout the battery (external protection) are the two most typical ways to slow down the thermal runaway propagation process. 4.1. Lithium-Ion Battery Thermal Runaway Internal Protection Technology
This method can issue a warning about 25 min before thermal runaway occurs, and achieved 100% accuracy during the experimental process. In summary, the proposed algorithm has successfully achieved early diagnosis and early warning of battery thermal runaway behavior.
Related Works There have been several studies on battery thermal runaway algorithms based on either model-driven or data-driven approaches. From a model-driven perspective, Ouyang et al. established an electrochemical–thermal coupling model to predict the voltage and temperature of lithium batteries during thermal runaway.
