Glad to see you posting again in your blog. My latest thought on the 90 day steps downs is that Nissan uses the first year to build a buffer on the battery to improve longevity and reduce the degradation. When I first got the car, Leaf spy read over 59kWh, which would only be a 4% buffer at the top. I looking at the other brands (Audi, Mercedes, even GM) it looks like 8-10% is a safer buffer. Supposedly even GM did a software update to hide about 2kWh on the Bolt battery (news Coulomb), but I don’t have anything beyond YouTube reports to back that up.
So Nissan gives you a tighter buffer in quarter 1, allowing for a higher epa range. It then slowly pulls a little away each quarter for a year (let’s hope just a year) to bring the buffer up. Now what we can’t see is in that first year, is how much the battery itself degrades, hence I believe some of the variations on the board. All hypothesis.
Let’s see what the next adjustment brings.
Wouldn't that be illegal? If the EPA rating is XYZ and then the carmaker steals that from you, that seems pretty shady. I know I signed a bunch of papers to the fact the battery would degrade, but I do not remember signing anything that Nissan could artificially degrade my battery. That sounds, if true, like a lawsuit waiting to happen.
WOE!!!! WTF!!! "artificially degrade??" Who said that?? What they are doing (maybe) is hiding part of the battery to protect it. Nothing more than what the Volt did among others.
