I need help interpreting some data.
I bought a used 2012 Leaf in June 2017 with 40k miles, but the battery had been replaced in December 2016 by the dealer at 35k. It now has 44k miles and still 12 bars. My normal driving consists of take a series of short trips, like 5 miles to work, but also includes a steep hill to get home. Tires are at 40 psi and I drive very conservatively. I was charging overnight at home with 110 current, but recently am able to charge at work with 220. It is warm here in Honolulu, but relatively cool where I live, and where I park during the day is covered parking, so temperatures in the 70s and 80s.
According to my LeafSpy, the SOH is 91.43% and Hx is 79.31%. Are these numbers unusual with a relatively new battery? I knew I would lose some % each year, but that is almost 9% over a year and a quarter, and with the newer, upgraded battery type (I think/hope). Does battery degradation accelerate, or what can I expect?
My other question is that according to the dash instruments, I get 4.5 Miles/KWh. But when I do this calculation myself I get a lower number, like 14 KWh having driven 56 miles or 3.9 miles/KWh. Should those 2 numbers be closer?
I really like the car, but it feels like I am charging more often that I should. After a full charge it says around 100 miles, but 56 miles later I am at 3 bars.
Thanks for any feedback.
