Summary The safety of lithium‐ion battery provokes public concern with its wide application. Considering the electrical and thermal interplay between different parts or layers, a multilayer electro‐thermal model is developed to investigate the performance in internal short‐circuit (ISC) case before the trigger of thermal runaway. The battery internal short circuit is assumed to occur under natural convection condition and the initial temperature is 25°C. In comparison, the simulation result agrees with the experimental data. It is found that the short‐circuit performance is quite sensitive to the number of layer and short‐circuit location. The current almost triples when the number of layer increases from 2 to 32. Moreover, weakening the electrical and thermal interplay between different layers can make the battery more secure in Al‐anode ISC case. It is proposed that adding extra resistance on two adjacent metal tabs or changing tabs’ position can improve the safety. Novelty Statement Electrical and thermal interplay between different layers is considered. Adding extra resistance between different unit layers protects battery from ISC. Weakening the electrical and thermal interplay between layers is recommended.

“…The temperature is observed during both experiments and its distribution on the core is compared. Over the lifetime of the battery cells, the non-uniformed distribution of the heat can create increased resistance and decreased capacity, and non-uniformed localized aging distribution [29]. In a battery pack topology, they might bring errors to the Battery Management System (BMS) estimations and aging evaluations.…”

Lithium-ion batteries (LiBs) performance can be significantly declined when operated at cold climates in terms of capacity loss, resistance increase and accelerated aging rates. To prevent this downgrade and to maintain the optimal operation of battery cells, a preheat process is taking place, which can be implemented either by internal or external techniques. The former is performed actively, by circulating a constant amplitude and frequency alternative pulse current (APC) at the battery cell’s terminal and preheating it internally by harvesting its generated Joule losses. The latter is achieved passively, by enclosing the cell into thermal blankets. In this work, a comparison of these two preheating strategies is presented, by proposing electro-thermal and lifetime models of a lithium nickel manganese cobalt oxide (NMC/G) 20 Ah pouch battery cell. Heat transfer, energy efficiencies and degradation costs are estimated during operation of the preheat techniques. Validation of the model showed a good agreement between the model and experimental data, and a study case is proposed to estimate and compare the cost efficiency of the methods as based for an economic study.

“…Various battery thermal management systems (BTMS) have been widely installed on HEVs and EVs [16][17][18][19][20][21]. During the repeated charging and discharging process, the battery module would generate a large amount of heat, especially at a relatively high rate [22,23]. The BTMS can avoid the rapid increase in temperature when the battery module is maintained at high temperature during a long time in some remote regions.…”

Electric vehicles (EVs) powered by lithium batteries, which are a promising type of green transportation, have attracted much attention in recent years. In this study, a thermoelectric generator (TEG) coupled with forced convection (F-C) was designed as an effective and feasible cooling system for a battery thermal management system. A comparison of natural convection cooling, F-C cooling, and TEG cooling reveals that the TEG is the best cooling system. Specifically, this system can decrease the temperature by 16.44% at the discharge rate of 3C. The coupled TEG and F-C cooling system can significantly control temperature at a relatively high discharge rate. This system not only can decrease the temperature of the battery module promptly but also can reduce the energy consumption compared with the two other TEG-based cooling systems. These results are expected to supply an effective basis of the design and optimization of battery thermal management systems to improve the reliability and safety performance of EVs.
