So regularly our honda accord PHEV has an after charge battery capacity of around 11-13 miles. We went on a long mountain trip where going down a mountain fully recharged my battery and now for the last two days the capacity after charging is 21 miles. It's a legit 21 miles because after driving 15 miles(with some hills), it still had 5 miles on it. Now, I'm not complaining about the new founded extra capacity, but anyone have any idea why I would now have this new capacity?
