A .04 adjustment is a win for sure.
Win? That is only on plus adjustments. This I call a closely fought but lost battle that could have been a coin toss especially when considering Nissan instrumentation.

Here is a 2 year report on a battery in the outback down under. Its still above 94%. I am beginning to think the 62 actually prefers warmer weather.

So about a 10 year lifetime at current loss rate until 'EOL' at 70% capacity of new. We tend to poo-poo Nissan engineering but they really do know how to match pack warranty with average real-world degradation.

Not great by any means, but solid if slow progress since Gen 1

An aside, I've never seen such a symmetric shunting across modules. Is that something new with 62 kWh packs ?

Like other evs, I don't think degradation is going to be linear. That said, the oldest Pluses are just over 2 years old, so we still have a few years to observe.

If the 2018+ has 3 temp sensors, what is the 4th sensor?

Then why do they read 4 different temperatures? Is one a motor/inverter temp?

It does make you wonder what the 3rds reading is for? Up until recently, it was simply blank. So the 3rd phantom number is what?? Average reading? Who knows. FYI; motor inverter temp is completely different data point and MUCH higher

One curious note on my last long drive was that even though SoH was lower than the last time I charged to 100% due to bms change, my gids were higher (by about 10). 725 vs. 715 last time. I thought that kind of odd. Car started garaged both time while charging and battery temp was similar at start of drive.
