In fact, there was a >50V difference in voltage at which the Phoenix range-test LEAFs turtled.
I originally said that, but it's not accurate. The two cars that had 350v-ish were just past the voltage "knee" at VLB, but had not made the plunge to 300v-ish at turtle. Therefore, those voltages should not be considered.
When I made the statement, I didn't qualify that important nuance. So, please just magically erase that from your memory!
In his most recent show, Jack Rickard of EVTV took your 50V difference and ran with it, concluding that there is no battery degradation but instead it is in fact a hall effect sensor error, and called it a BMS issue. Just remember, Jack loves to speak with authority on a subject, even if he's completely wrong.
Ya, I saw that. Of course, I did not share that info with him for it to be his news peice. I just read off some voltages when he asked, and that included the two cars that were not at turtle (which, again, I did not tell him, as I didn't here).
I think many of us confuse the instruments with stored energy, even after our range test. Sure, the BMS could be one issue, and I'd bet that the Hall effect device is probably not doing its job perfectly, but there's little doubt in my mind that heat accelerates battery degradation. Actually, the body of evidence is overwhelming.
So, Nissan claims no problem because they have data that shows most cars on a "glideslope". Obviously, losing 4 bars doesn't appear to we little people as any glideslope that makes sense, unless you understand the context of 7500 miles per year is what they base that on (in Nissan logic, that was NEVER disclosed). Four Bar Loser Scott Yarish has 29,000 miles divided by 7500, to equal almost 4 "NISSAN-YEARS(TM)" of driving. Naturally, Nissan-Years(TM) don't apply to the lease, where the standard is 12,000 miles, and for just a few dollars more, 15,000 miles.
So, with a slight of hand, 80% in five years is re-indexed to 76% at five years, and now it all makes sense. Heck, Yanquetino would require Scott to apologize for complaining of a 30% loss in a little over one year; it's "normal" to Nissan, but NOBODY outside this little island of thought would likely agree. It is EXACTLY this (undisclosed) bullsh*t that they won't win in court, or the court of public perception of ALL electric cars. I'd be happy to sit outside a Nissan dealer for an afternoon taking a survey, "Sir/Madam, would you consider the purchase of any car you may buy from this Nissan store to be normal if it had a 30% loss of range in a bit over one year? That's what Nissan claims for their new electric car, the LEAF. Have a nice day."
So, how many Nissan-Years do you have on your LEAF? One more interesting bit of the puzzle; in another two or three brutal summers, with normal Nissan-Year driving of 7500 miles per year, Scott would be looking at a number far greater than 30% loss for 29,000 miles.
