Free QuoteThis paper presents a method of detecting a single occurrence of various common faults in a Lithium-ion battery pack and isolating the fault to the faulty PCM, its connecting conductors, and joints, or to the sensor in the pack using a Diagnostic Automata of configurable Equivalent Cell Diagnosers.
To monitor the pack, parallel execution of fault diagnoser for every single PCM is needed, which is computationally intensive. A single faulty cell of a PCM, a faulty sensor, or a faulty connection can substantially reduce the whole battery pack's performance or cause a hazard.
Data-driven techniques such as PCA, , Shannon-entropy and correlation coefficients, detect faults in battery packs by exploiting the cell-to-cell relationship, however, these methods cannot specifically identify and classify SCs.
Diagnostic algorithm is executed on a microcontroller and tested in real-time. 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.
Micro short detection framework in lithium-ion battery pack is presented. Offline least square-based and real-time gradient-based SoH estimators are proposed. SoH estimators accurately estimate cell capacity, resistances, and current mismatch. Micro short circuits are identified by cell-to-cell comparison of current mismatch.
Abusive lithium-ion battery operations can induce micro-short circuits, which can develop into severe short circuits and eventually thermal runaway events, a significant safety concern in lithium-ion battery packs. This paper aims to detect and quantify micro-short circuits before they become a safety issue.
