This 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.
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.
Lithium-ion (Li-ion) Battery Packs (LIBP) have become the main energy storage element for many applications like Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs), and smart grids. The battery packs are built to achieve specific voltage and current ratings by connecting multiple Li-ion cells in series–parallel combinations.
The proposed approach is validated using experimental external short circuit (ESC) data from a 22-cell module in a battery-electric locomotive (BEL). We also present and validate an online implementation of the proposed fault detection technique to detect and quantify the SCs in real time. Fig. 1. Schematic of the proposed SC detection framework.
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.
