Can a lithium-ion battery pack detect a single occurrence of a fault?
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.
What is a fault mechanism in a lithium ion battery?
Fault mechanisms LIBs suffer from potential safety issues in practice inherent to their energy-dense chemistry and flammable materials. From the perspective of electrical faults, fault modes can be divided into battery faults and sensor faults. 4.1. Battery faults
What is a diagnostic algorithm for lithium ion battery packs?
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.
Can structural analysis be used to identify faults in a battery pack?
Liu et al. applied the structural analysis theory for a battery pack to detect and isolate the various sensor faults and cooling system faults. A comparison is performed between the hardware redundancy and analytical redundancy-based fault identification methods in terms of practicability and functionality, which is listed in Table 9.
How do you determine fault occurrence in a battery pack?
Lin et al. used the variation in the voltage difference between different cells (d Δ U) as a fault index and calculated the correlation coefficients between different cell voltages and d Δ U s for battery pack consistency analysis to determine fault occurrence.
What is a lithium ion battery pack?
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.
