We need a place to post battery info, temperature observations, and other things relating to the new 40kwh pack. There are a few stats scattered in other topics, but having this one should make it easier to keep track of them. Links to the other posts would be a good idea.
When I went to pick up my 2018 SL the other evening, I took advantage of my salesman's need to finish up with other customers to take a quick LeafSpy reading. Here are the main stats (I'll try to post a snap of the screen later):
The pack looked extremely well balanced - no shunts at all, IIRC, and all the voltages close. SOC was 95% or so.https://photos.app.goo.gl/RnFL3g7tvMELhFhC8
Moving on to pack temp observations, I have a suggestion: since the temp gauge is a little...subjective to read, it might be best, when LeafSpy isn't available, to estimate the readings as a percentage, with the far left side of the virtual bar gauge being "0%" and the far right, at the end of the red zone, as 100%. Using that metric, I started the car this evening with the ambient temp at 86 or 87F, a huge rise after a morning low of 46F. The pack was still fairly cool, and I would estimate the gauge was reading "40%" along the scale - somewhat to the left of the middle. I also used an infrared touch-less thermometer to read the exterior (Scarlet) body temp (112F) and a digital thermometer I'd left in the backseat to measure the interior (black/grey seat covers and white trim) temp, which was 104.5F. All of this means little of course, because the pack, with its large thermal mass, hadn't warmed to anywhere near ambient.
It might also be interesting to get other readings of steel body panels (with color noted) in full sun, and interior temps with windows both closed and partially open, along with gauge and LeafSpy readings. One comparison I was able to make today was of my Scarlet Ember Leaf's body in full sun (112F), vs my housemate's "Sea Mist Pearl" (very light green/blue) Prius PHEV (99.5F) also in full sun, behind my car. I'm kind of wishing I'd gone with another Brilliant Silver Leaf after all...
