The above diagnosis results are entirely consistent with the fault injections in Table 3, which indicates that the method proposed in this work can accomplish the detection, isolation, and localization of concurrent multiple faults in lithium-ion battery packs.
Pack 1 consists of 8 cylindrical 21700-type lithium-ion battery cells connected in series. The specifications of the cell are shown in Table 1. The capacity inconsistency among the cells is evaluated using the discharge capacity, which is measured under 1 C constant current discharge at an ambient temperature of 25 ∘ C.
In each charge–discharge cycle, the battery pack experiences at least two types of faults, accompanied by inconsistencies among cells. In other words, this study considers scenarios where different types of faults coincide, which is fundamentally different from existing researches where only one type of fault occurs at a given moment.
In response to the identified limitations of the existing methods, this study introduces a multi-fault diagnosis method for lithium-ion battery packs based on random convolutional kernel transformation (RCKT) and Gaussian process classifier (GPC).
Following that, the extracted features are fed into the GPC to classify the fault modes, thereby combining with the adopted interleaved voltage measurement circuit to achieve the detection, localization, and isolation of concurrent multiple faults in lithium-ion battery packs.
However, the need for protection circuits to maintain the voltage and current within safe limits is one of the primary limitations of the lithium-ion battery.

A battery pack is a set of any number of battery cells connected and bound together to form a single unit with a specific configuration and dimensions. They may be configured in series, parallel or a mixture of both to deliver the desired voltage, capacity, or power density. Packs are identified by cell size, number of cells, battery structure, chemistry, chargeability, capacity, and voltage ...
As indicated in Table 1, target energy metals – except for lithium – are present in the highest concentrations in thermal pre-treatment''s matte.The matte reports higher concentrations than the mechanical pre-treatment''s mixed active materials since it does not include the graphite anode materials, the oxygen from the CAM''s transition metal oxide, nor …

Battery abuse faults include, in the main, over-charging, over-discharging, external short circuits, and internal short circuits (ISCs). Among them, the ISC is one of the most common causes of thermal runaway in lithium-ion batteries, typically triggered by various abusive conditions during operation [8], [9].
Lithium-ion battery packs are typically built as a series network of Parallel Cell Modules (PCM). A fault can occur within a specific cell of a PCM, in the sensors, or the numerous connection joints and bus conductors. This paper presents a method of detecting a single occurrence of various common faults in a Lithium-ion battery pack and ...
