“…In addition, 1 Ω to 100 Ω and ∆t ISC ∈ [1; T − t ISC ] were chosen as boundaries for the fault resistance R ISC and fault duration, respectively. The selected range is in accordance with various recent studies [40,49,61,88]…”

“…This illustrates that usually the presented detection methods are not tested against fault-free data and therefore T n = 0. If TPR (sensitivity) and FNR (specificity) have been calculated for different detection method parameters and test boundaries, they can be plotted as conducted by Meng et al [40]. The resulting curves are called the receiver operating characteristic (ROC) curve and provide the opportunity to identify the parameters for an optimized classification result.…”

“…This lack of the ability for comparison is, inter alia, caused by the large variance in validation data and the known or unknown boundary conditions and due to the sensitivity of gathered results to the experimental design [40]. In addition, the results are often based on assumptions [41], which further hampers comparability.…”

Various methods published in recent years for reliable detection of battery faults (mainly internal short circuit (ISC)) raise the question of comparability and cross-method evaluation, which cannot yet be answered due to significant differences in training data and boundary conditions. This paper provides a Monte Carlo-like simulation approach to generate a reproducible, comprehensible and large dataset based on an extensive literature search on common assumptions and simulation parameters. In some cases, these assumptions are quite different from field data, as shown by comparison with experimentally determined values. Two relatively simple ISC detection methods are tested on the generated dataset and their performance is evaluated to illustrate the proposed approach. The evaluation of the detection performance by quantitative measures such as the Youden-index shows a high divergence with respect to internal and external parameters such as threshold level and cell-to-cell variations (CtCV), respectively. These results underline the importance of quantitative evaluations based on identical test data. The proposed approach is able to support this task by providing cost-effective test data generation with incorporation of known factors affecting detection quality.

“…In order to study the triggering conditions and thermal runaway characteristics of batteries, Zhu et al conducted a battery thermal runaway experiment induced by overcharge conditions on large-sized lithium-ion batteries [10,11]. The results show that the main causes of thermal runaway can be divided into electrical abuse, thermal abuse and mechanical abuse [12][13][14][15][16][17][18][19][20].…”

This study aimed to achieve a clear understanding of the response characteristics of soft pack battery extrusion conditions under various situations. In this study, we chose a LiCoO2 battery as the research object of the extrusion experiment. First, the repeatability of the extrusion test on the battery was verified. A quasi-static extrusion test was conducted on three groups of batteries in the same state, and the load-displacement curves of the three groups of experimental batteries were almost the same. Then, the influence of the extrusion speed on the battery thermal runaway was studied. The results show that a different extrusion speed has a certain impact on the thermal runaway performance of the battery. The peak load of the battery is lower at a lower speed. Finally, the study found that every 20% change in SOC has a greater impact on the battery response under a squeeze. The larger the SOC, the more severe the battery thermal runaway. Through an analysis of multiple experimental cases, it is possible to have a deeper understanding of the temperature and voltage characteristics of lithium batteries when a thermal runaway occurs, which provides ideas for monitoring the trend of the thermal runaway of electric vehicles.

“…To settle the above-mentioned difficulties it is proposed to use the Takagi-Sugeno model of the battery system [24][25][26]. Such models have proved to be very useful both for modeling and control of possibly time-varying and/or nonlinear systems [24].…”

Among the existing estimation schemes of a battery state of charge, most deal with an assumption that the faults will never occur in the system. Nevertheless, faults may have a crucial impact on the state of charge estimation accuracy. The paper proposes a novel observer design to estimate the state of charge and the remaining useful life of a Li-ion battery system under voltage and current measurement faults. The approach starts with converting the battery system into the descriptor Takagi–Sugeno form, where the state includes the original states along with the voltage and current measurement faults. Moreover, external disturbances are bounded by an ellipsoid based on the so-called Quadratic Boundedness approach, which ensures the system stability. The second-order Resistor-Capacitor equivalent circuit model is considered to verify the performance and correctness of the proposed observer. Subsequently, a real battery model is designed with experimental data of the Li-ion 18650 battery delivered from the NASA benchmark. Another experiment deals with an automated guided vehicle fed with a battery of which the remaining useful life is estimated. Finally, the results are compared with another estimation scheme based on the same benchmark.
