Additionally, for the study of lithium-ion batteries with internal short circuits, we need to pay more attention to the maximum temperature and temperature rise rate of the battery. In this section, experiments and analysis were conducted on cells A and B at 40 % SOC without thermal runaway.
Therefore, the severity of the internal short circuit of the lithium-ion battery can be analyzed and diagnosed by the CNN model. Table IV. Performance comparison of battery internal short circuit diagnosis model.
In order to establish the internal short-circuit model of lithium-ion batteries, this paper refers to the research of Feng et al. 18, 19 introduces the internal short-circuit resistance (Rshort ) of the battery, and then couples it with the electrochemical model.
The circuit model for battery can be expressed as Eq. (1), where Up represents the polarization voltage, Ut denotes the terminal voltage, and I signifies the current . 2). Thermal Model: This part of the model utilizes a first-order thermal network to simulate the dynamic temperature response of the lithium-ion battery.
Internal short circuit (ISCr) is regarded as one of the major safety risks for the lithium-ion batteries. While most of the ISCr incidents only result in poor battery performance, some of them do lead to the thermal runaway and may further results in fatal accidents, 1, 2 which are unaffordable for consumers.
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
