I’m trying to find out the shape of the curve that reflects electro vehicles battery degradation data (depending on cumulative travelling distance). The red line on the plot doesn’t seem a perfect fit. Is it stretched exponential of some sort?

So, as I do not fully understand the nature of the process, I cannot figure out what would be appropriate distributions for such continuous variable as remaining capacity.
Any tips will be much appreciated.
