Well, what do we know so far?
Well, the Tesla pack being 3X the cost "should" last 3X longer and it has but it would appear we are being swayed by a handful of overly publicized packs that have piled a lot of miles on. In those cases, QC use was extreme and the time to pile on the mileage was short.
BUT, we also have LEAFers who have done the same thing. We have a Uberite exceeding 120,000 miles on his LEAF and still has 11 bars. Granted, 11 bars is not 12 bars but he is running on a 24 kwh pack. So he has beat the clock by all measures. What is his secret?
Well, not much of a secret because like some of the well known 250,000 mile Teslas, he QCs several times a day and has piled on his mileage in a very short period of time.
Now we have my 2016. I didn't QC nearly to the degree these people did but did do so more than the average. I racked up nearly 30,000 miles in 14 months suffering little degradation (VERY little) that included a 116.2 mile trip on a single charge in January 7 days before her untimely demise. (Yeah, that Winter range degradation hit me hard!!
I really think I could have had a monumental vehicle stat to brag about a few years from now but the accident made me realize that I was working towards a direction that was not in my best interest so within 2 months of getting my 2018, I changed jobs. So, no chance to see how well the 2018 would have stood up to the challenges my previous job presented although I will say for the 2 months, it was a pretty awesome improvement!
So as I reach 9,000 miles on my LEAF with 4X the degradation my 30,000 mile 2016 had, the initial results are interesting. I cannot jump to any conclusions right now simply because the degradation LEAF Spy has reported has not translated into reduced range. Now with so much range that I rarely need to access, I might simply be unaware of small loses so I have to say...
