Had an interesting experience yesterday. I drove a little over 200 miles yesterday and hit the QC 3 times and L2 once at lunch. My Leaf Spy stats have jumped! Just FYI my car is a 8/13 SV with 28k miles been living in Colorado its whole life and from what I can tell it had pretty decent stats to start with. Also temperatures were between 20F and 40F and back down to 20F on the way home yesterday, and even some snow.
When I bought the car it had 61.8AH and Hx and SOH were both around 92-93%, no screenshots of that unfortunately.
These are the stats leaving the house, notice they got better since I bought the car. 62.5Ah, SOH = 95%, Hx = 96.25%
After my 2nd QC of the day the stats jump to 62.8Ah, SOH 95%, Hx = 96.6%
I QCed one more time on the way home but didn't check the stats after that.
Then I turn on my car this morning after 100% L2 charge and here's the numbers, 64.68 AH, SOH = 98%, Hx = 99%
Not only are my stats better, but it appears my cell balance is also better. I guess I'm just going to keep an eye on the stats and try and figure out how much of this is because I'm driving it regularly and taking care of the battery, how much is artificial because of a string of quick charges (not sure why that makes it better), or something else.
Also quick charging works pretty well at this time of year, but I couldn't imagine doing more than 1 QC in spring or especially summer. The battery heats up quick and as far as I can tell takes forever to cool off, even in 20F air while driving gently. I can't imagine the temperatures it could potentially reach in summer.
