Hello, Everyone!
I need a Python or Matlab code that calculates the cyclic and calendric aging of LFP batteries. There are numerous semi-empirical aging models for lithium-ion batteries, but I need a code that works properly for LFP batteries, for instance, Sony Murata US26650FTC1A. I used the "Blast" model, but it doesn't give sensible results for low temperatures. This model should work well for temperatures in the range of -35 to 35 degrees centigrade. It would be great if anyone could help me in this matter.
I'm interested in finding a model that represents the physical and chemical processes involved in battery ageing, taking into account the effect of temperature and hysteretic energy consumption. Each component can be described by an equation of state that gives the parameters of a reliability law. Several techniques can be used to measure these parameters. This approach is based on the laws of physical chemistry and involves no approximations or assumptions. IF you are interested in this idea please contact me.
Hello @Claude Le Gressus
Thanks for your answer, But I need a model to calculate end of life , to do some calculations in the field of Battery Electric Vehicles. Studying the physical and chemical properties of the batteries, is out of the scope of my project. I just need a model to calculate end of life, by means of SOC, Temperature, Crate, time,...
