A spreadsheet I created to optimize the charge of electrical car.

Spreadsheet to calculate lifetime miles before battery degrades to 70% of capacity.

I simply used the data I saw at a published link. Based on this, for most users 80% to 20% is probably the sweet spot compared to 100% to 20 or 30% most users may now be doing.

I would like comments on your own experience with your car to help others.
