Dear colleagues,
i am trying to carry out a model for the aging of li-ion battery to predict the battery's lifetime. However, as i don't have any experience with it, i would super grateful to get help with it. i have all the required data like SOC, DOD, T, t and C-rate and all other data regarding cycling and calendar tests. would be really grateful to get help over this.
thank you in advance.
Dear Rehab,
usually the influences for calendar and cyclic aging models are considered seperately and then modelled. The temperature influence on the capacity is often modelled after the Arrhenius-effect: f(T) = e(-b/T)
The following two documents give a good overview and models you could use:Article Impedance change and capacity fade of lithium nickel mangane...
Article Combined cycling and calendar capacity fade modeling of a Ni...
As a starting point, you could use these models and try to fit the missing parameters with your dataset.
Kind regards,
Christian
Dear Christian,
Thank you so much for sharing these information. The documents are quite useful and have an intro about what to be done. Thank you again and wish you a good day.
