Thermal runaway in lithium-ion batteries poses a major safety risk to electric vehicles and energy storage systems. Current early-warning methods depend mainly on temperature and may therefore miss mechanical precursors that emerge before rapid heating.
The paper presents a two‑stage early‑warning system for detecting lithium‑ion battery thermal runaway under mechanical abuse. Stage I estimates localized thermal instability from infrared hotspot dynamics, achieving an ROC‑AUC of 0.945. Stage II fuses this instability score with mechanical, electrical, thermal, and image‑intensity features, reaching an ROC‑AUC of 0.908 and providing a 14.8‑frame mean lead time before voltage‑based detection.
arXiv:2607. 16864v1 Announce Type: new Abstract: Supercharging of lithium-ion batteries (LiBs) requires robust health monitoring to ensure durability, safety, and user confidence, particularly for emerging vehicle-to-grid applications with bidirectional energy flows.
The paper introduces Relative Discharge Stage (RDS), a battery‑management indicator that classifies remaining discharge condition into five interpretable classes—Normal, Good, Moderate, Low, and Recharge Required—without needing future load information. It combines physics‑based SOC estimation with a lightweight temporal convolutional network that processes measured current, voltage, temperature, and SOC over a sliding window. Experiments on two public lithium‑ion datasets show RDS classification accuracy above 80% across varied load and thermal conditions.
