Hi reader,
I am working on a model that will predict the % of battery degradation as a part of my academic project. I am finding individual factors, but could not form an equation with different factors and weights. (refer example below)
d (a,b,c) = x . a + y . b + z . c
Thanks in advance and happy researching ✌
BR,

It is not clear what kind of research you are doing: whether it concerns storage or operation.
For storage, everything is relatively simple: the variable is time, the main parameter is the initial state of charge, the response is the residual charge or voltage (easier to control). But for operation, there are many techniques, ranging from artificial cycles (constant C and D-rates and intervals between cycles), ending with a certain combination of charges, discharges and "rest", more or less simulating the actual functioning of the battery in a particular application.
Have a look on the empirical aging model from our group, where the weights for different stress factors are fitted with the aging dataset. Article Calendar and cycle life study of Li(NiMnCo)O2-based 18650 li...
