Summary: An efficient battery thermal management system is developed to control the battery temperature and prevent thermal runaway. The specific heat capacity and heat generation rate of a large-capacity battery are determined using the calibration calorimetry method. Three different thermal management systems are proposed, and Case 3, which combines composite phase change material (CPCM) with liquid cooling, exhibits the lowest maximum temperature of the battery module. Various parameters, including CPCM thickness, coolant velocity, ambient temperature, and discharge rate, are studied to optimize the thermal performance of Case 3. The results demonstrate that Case 3 effectively controls the maximum temperature and temperature difference of the battery module, enhancing the thermal safety of batteries.

Summary: An innovative hybrid data-driven estimation method is proposed to accurately and reliably estimate the state-of-health (SOH) using failure feature extraction. Influencing factors on lithium-ion power battery failure are studied, and three failure features are extracted using fuzzy grey relational analysis (FGRA) as inputs for the estimation model. The improved Least Squares Support Vector Machine (LSSVM) model is then applied to estimate the SOH under different ambient temperature conditions. Results show that the proposed method has higher accuracy compared to SVM, with estimation errors less than 0.02 and a mean square error accuracy of 0.00001.
