Summary: Internal short circuit (ISC) is a major cause of battery thermal runaway in EVs, posing serious safety hazards. However, accurately diagnosing ISC in the early stage is challenging due to limited electrothermal characteristics. Existing diagnostic methods often ignore battery consistency. Therefore, a novel quantitative ISC diagnosis method is proposed, which analyzes the variation of charging electric quantity in a fixed voltage window before and after ISC occurrence. This method successfully applies to both laboratory constant-current and real vehicle step-current charging conditions, ensuring accuracy within 6%.

Summary: With the rapid growth of the electric vehicle industry, the use of lithium-ion batteries has greatly increased. However, these batteries are susceptible to thermal runaway, resulting in fires and explosions that pose serious risks to electric vehicles. Therefore, finding an effective method to prevent and suppress thermal runaway in batteries is crucial. This study proposes the use of a lithium-ion battery module with cylindrical cells and paraffin phase change material, which can effectively reduce the maximum temperature of the trigger cell and prevent thermal runaway propagation. The influences of thermal conductivity, latent heat, melting temperature, and thickness of the phase change material on heat generation and temperature during thermal runaway are analyzed, and design recommendations for phase change materials to protect lithium-ion batteries are provided.

Summary: The label-less characteristics of real vehicle data pose great challenges for engineering modeling and capacity identification of lithium-ion batteries. The randomness and unpredictability of vehicle driving conditions, sampling frequency, and other factors in the raw data collected from driving cycles have adverse effects on effective modeling and capacity identification. Therefore, data cleaning and optimization are necessary, and the capacity of a battery pack is identified using the improved two-point method. By utilizing the charging and discharging data segments and a Fuzzy Kalman filter optimization capacity estimation curve, the current available capacity is obtained. This algorithm is integrated into a new energy big data cloud platform. The results demonstrate the successful application of the capacity identification algorithm in academic and engineering fields through charge and discharge mutual verification, meeting the engineering requirements for life expectancy.

Summary: In this study, an in situ observation method for thermal runaway (TR) and its propagation (TRP) in lithium-ion battery electrodes was proposed using high-frequency induction heating as the TR triggering mechanism. The non-contact, rapid heating technique enabled direct observation of TRP. It was found that venting occurred in all samples and dendritic burn patterns appeared on separators during TRP. The heat-induced shrinkage of separators was more pronounced on the anode side. Phenomena observed during tests included gas flow paths, drifting sparks, short-circuit propagation, and electrolyte boiling. This method contributes to a better understanding of LIB TRP behavior and facilitates strategies to enhance safety and TR characteristics.
