Re: The 40KWH Battery Topic

To find out if I'm right we would need daily HX readings from a bunch of folks along with their SOC - and maybe not just average SOC, but also max and min. And I could be totally wrong and its all a coincidence. There could also be other factors, such as DC Fast charging, which I don't really do, and temperature could also play a role.

My car last night was sitting at a SOC around 67% and HX went down slightly.

I also should have my next 3 month adjustment any moment.

Current stats:

SOH = 90.04
AHr = 103.94
Hx = 103.58
364.94 V
65.4% SOC

ODO = 8070 miles

Here are my Leaf stats for my 2 Leafs. Both 62s, but I can't figure the Hx.

Except for SOH and mileage, basically a random number generator.
#1 Leaf SL MY 9/13: 76K miles, 47 Ahrs, 5.0 miles/kWh (average), Hx=70, SOH=73, L2 - 100% > 1000, temp < 95F, (DOD) > 20 Ahrs
#2 Leaf SL MY 12/18: 10.3K miles, SOH 109Ahrs/115Ahrs, 5.2 miles/kWh (average), DOD > 20%, temp < 105F

Were you asking me?

I have no idea. But HX appears to move slowly, and my temp various quite a bit over a 24 hr period, and i have not seen HX moving over the 24 hr period with temperature.

But in the long run, does temp impact HX? Sure, maybe, who knows.

Does fast charging impact HX? I don't know that either. The last three fast charges I have done were testing the new site near me, and I went from ~ 25% to 50%, and never noticed a jump in HX afterward. But those are pretty minor Fast charge sessions, I think.
Maybe Fast charging impacts HX when you start to charge above the 75% range?

I would be very curious to see the HX of someone who never charges above 75% and never lets it drop below 20% versus someone who charges to near 100% daily?

Could... This is why I always record measurements before the first drive of the day...most of the time. For days like today; I got up this morning and plugged in as always. Have a few errands to do and probably a large chunk of free time (which has become common lately) so not sure what I will do with that but a 3 hour charge brings me to about 55% which will more than cover my needs likely more than 2X. I will check stats in a few but not likely to leave the house until near noon. My "normal" day consists of plugging in in the morning and unplugging when I leave for work which gives me about 75 minutes of charge time.

Either way, I think setting a sort of schedule to check is best. I have a garage so its easy for me to buzz back and forth. If I was parked outside, I would likely elect to check it when parking for the night instead.

24,300 miles 2 years 9 months. Next month is my recalibration, will it go up :) or down :( ?

I'm hoping with the cold weather it goes positive.

No change. I would highlight your Jan 2020 as green as well since there was no change on that one either. FYI; my only positive reading came in July...

I was surprised to see how much his battery warmed in a cold day with the 40 pack. Do others see this too?

I can say the 62 pack doesn't warm nearly as much if at all when its below 50F/10c.

Well, as of this AM I did not get a 3 month update. It should have happened by now if it was going to happen.
My numbers this morning are essentially the same as those above.

So like clockwork I had gotten a 3 month update, then last update was the first time I gained SOH. Then this update did not occur.
