The 40KWH Battery Topic

You only get a number of stars. It's a lame readout although AFAIK, no one knows what information Nissan actually receives. One would think they would get a lot of logs of usage, etc but they don't share anything with the customer. It's possible the dealer doesn't even see that data and that it just goes back to some data base in Nissan HQ or something.

So until someone loses bar #1 on a 2018 or 2019, we have no real idea if SOH in leafspy is working.

Anyone loose a bar yet? Someone who bought early in 2018?
When were the first 2018's delivered? That means 1.5 or almost 2 years in, no one has lost a bar.

Also like you, no matter what i do it still drops. But i do try keeping it around 40-70 SOC. I only have 3 QC and not by me.
I live in the midwest so its can get hot and humid but nothing compared to the southwest desert.

I was also playing around with cooling the battery somehow. I opened up the access cover on the back seat floor. I can feel the air when driving. When i put a bright light in the access hole and turn off all the lights in my garage and look under the car. I can see light coming out. You can see the airflow passages. But even if i try putting a fan in there or no matter what i do, i still loose about .01 a day or every other day no matter what. VERY DISAPPOINTING!!

What's your mileage though?

We are only around 1900 miles.
Almost looks like mileage doesnt matter.

Have any 40’s lost a bar yet.

Do the SOH changes seem to correspond to a loss in range of the same magnitude?

Maybe, but we haven't seen it documented yet. Cwerdna saw a Facebook post showing a 40kwh dash display with 3 bars gone, FWIW.

Maybe. I'm down close to 10% I'd guess, and my GOM shows 130 miles more often than 150 now. I don't take 150 mile drives.

Why is the FB report not "documentation" ?

My mileage is 2400. I don’t think mileage matters either.

Ok thanks. But our mileage is pretty close too. I'd be curious to see a 2018 with 20k miles.
