AI Customer ServiceThe heat generation model of the battery was established using experimental data and verified by assessing the heat generation of the battery at 1C charge and discharge, as shown in Fig. 2 (a) and Fig. 2 (b). The errors of predicted heat generation were within 10 % compared to the Liu et al. .
Based on the experimental data, the new correlations were proposed for the battery maximum temperature, heat generation, entropic heat coefficients, and internal resistance for charge/discharge state. The proposed correlation estimates heat generation with high accuracy lower than 10% compared to the measurements.
Resistance to Charge Transfer: this resistance can also generate heat during charge and discharge processes, Occurring at the interface between the electrolyte solution and the electrode materials. Electric Resistance within Battery Components: This resistance is intrinsic to various battery parts and contributes to heat generation.
The results show that for the state of charge, the dissipated heat energy to the ambient by natural convection, via the battery surface, is about 90% of the heat energy generation. 10% of the energy heat generation is accumulated by the battery during the charging/discharging processes.
As a result, a lumped thermal model with a “cell average temperature” can be used to calculate battery heat generation, which could provide accurate temperature estimation results in battery management system applications [24, 25]. And the simplicity of the lumped model makes it very suitable for online applications .
Furthermore, the research extends its reach into developing a sophisticated battery thermal management system. This system ingeniously incorporates heat pipes alongside a nonlinear model predictive controller (MPC). The synergy of these components yields precise temperature regulation and notable reductions in power consumption.
