Due to the coupling effect of multiple cells, the thermal safety of a Li-ion battery pack is different from that of a single cell. Previous studies usually assumed the same loads and model parameters to facilitate calculations [19, 22].
Lithium-ion battery packs (LIBPs) play a crucial role in electrified transportation systems. The cost of LIBPs has a substantial impact on the manufacturing expenses of electric vehicles (EVs), typically representing 25% of the total EV production cost 1, and 75% of the powertrain cost 2.
Model parameters To verify the feasibility of the proposed method, a typical 4 × 6 parallel–series battery pack composed of NCR 18,650-B is employed considering the trade-offs between the sufficient coverage of simulation samples and the accuracy and complexity of the multiphysics model.
Therefore, the thermal safety risk of a battery pack can be evaluated based on the SSI model . In this study, the critical ambient temperature Tam,cr and critical operating power Pb,cr are taken as the physical quantities of strength to characterize the TR of the electrochemical exothermic system.
The main challenge in charging a Li-Ion battery is to realize the battery's full capacity without overcharging it, which could result in catastrophic failure. There is little room for error, only ±1%. Overcharging by more than +1% could result in battery failure, but undercharging by more than 1% results in reduced capacity.
Safety risk evaluation of battery pack To evaluate the safety risk of the battery pack, the critical ambient temperature and operating power need to be coupled for thermal safety analysis. Based on the randomness and distribution types of parameters in , the Monte Carlo method is used for combined sampling.
