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.
Internal short circuit is a very critical issue that is often ascribed to be a cause of many accidents involving Li-ion batteries. A novel method that can detect the Internal short circuit in real time based on an advanced machine leaning approach, is proposed.
After training with large amounts of labeled battery fault data, Naha et al. detect short circuits up to C / 429 leakage current in lithium-ion battery cells using a random forest classifier, with 97% accuracy. Model-based approaches can detect and isolate SCs by leveraging the battery physics.
Statistical testing results show fast and accurate fault detection capabilities. 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.
Many effective methods have been reported in the literature for ISC detection using a range of statistical measures, estimation techniques, observer designs, etc. The correlations between the different voltage curves of various cells present in a battery pack have been used to detect the short circuits 34.
