Fault diagnosis and abnormality detection of lithium-ion battery packs

Battery abuse faults mainly refer to external short circuit (ESC), internal short circuit (ISC), overcharge and over-discharge. Sensor faults usually indicate abnormal operation of current transducers as well as voltage and temperature sensors, and connection faults are usually caused by loose contact between neighboring cells.

6 FAQs about [Battery pack failure three-level alarm reason]

What causes low accuracy of battery energy storage system fault warning?

The current research of battery energy storage system (BESS) fault is fragmentary, which is one of the reasons for low accuracy of fault warning and diagnosis in monitoring and controlling system of BESS. The paper has summarized the possible faults occurred in BESS, sorted out in the aspects of inducement, mechanism and consequence.

How do I know if a battery pack is faulty?

For levels above the battery pack, only possible fault information can be obtained from the product description of system devices. The extraction of the mapping relationship from symptoms to mechanisms and causes of failure is incomplete. There are many failure causes and failure modes of BESS.

What causes a battery pack to fail?

For modules and battery packs, the failure in pack level mainly depends on thermal runaway propagation, which has been described in Section 4.5. External short circuit of module or battery pack should be paid special attention. External short circuit of large capacity energy storage battery would directly perform thermal runaway.

How can faults detection and abnormality of battery pack be detected?

As discussed above, the faults diagnosis and abnormality of battery pack can be detected in real time. In addition, timely detection and positioning of faults and defects of cells can improve the health and safety of the whole battery pack.

What causes a battery to fail over a short time horizon?

Fault over a short time horizon based on voltage difference and monomer voltage are diagnosed. Cell voltage inconsistency of a battery pack is the main problem of the Electric Vehicle (EV) battery system, which will affect the performance of the battery and the safe operation of electric vehicles.

What are the causes and influencing factors of battery failure?

In the published accident investigation reports of BESS, failure causes and influencing factors would be summarized as follows: defects in battery cell, defects in components, external excitations, application environment, system layout, state of battery and management system defects.
