What are common battery failures?

In an acid stratified battery, shedding, corrosion, and sulphation happen much faster at the bottom of the plate, leading to earlier battery failure. Moreover, modern vehicle batteries that operate in a Partial State of Charge (PSOC) seldom receive a full charge and/or are constantly deeply cycled or micro-cycled combined with acid stratification to accelerate shedding and corrosion.

6 FAQs about [New energy battery failure and loss of warranty]

Can a faulty battery be covered under a warranty?

It is often only when capacity drops to below an overall percentage, typically 70%, that the battery warranty kicks in and that means that it is possible to have a faulty battery delivering 71% of what it should be delivering, from day 1, and it is not covered under the terms of the warranty.

Does EV battery warranty cover premature failure?

Totally agree but that is the issue I have with EV battery warranties. It doesn't warranty against premature failure - It warrants against degradation of capacity of the whole battery of more than 30% (capacity down to 70%) overall. There is no mention of individual cell degradation or failure.

Is 8 year battery warranty a good idea?

The car was sold with an 8 Year battery warranty specifically to reassure EV buyers that they aren't going to be landed with a huge bill within 8 years. I point out that a cell failure can only be a poorly manufactured cell as the expected wear and tear predicts a decline of no more than 35% (ish) over an 8 year period.

Why does my eV have an 8 year battery warranty?

At this point both me & the service team were shocked to hear this. The car was sold with an 8 Year battery warranty specifically to reassure EV buyers that they aren't going to be landed with a huge bill within 8 years.

Why do lithium-ion batteries fail?

These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.

What is physics-based battery failure model?

PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.
