On the slower Chademo's I agree. I charged from 29% to 80% on an EVGO last night (NC2C thank you) and it only raised the battery 1 temperature bar (from 4 to 5 bars).

The temperature does go up quicker on the 75+ KW EA chargers.
WOW! How long did that take? Sounds like you have a LOT more patience than I do.

It was on the charger for about 45 min. I was at Walgreens waiting for my son, so it wasn’t really difficult. I am just struggling in whether the Chademo sessions are going to accelerate the battery decline or not vs. never needing to put for power.

I have about 10 different NC2C or free Chademo sites within 10 miles of my house, so really anywhere I go close it’s not a big deal (grocery shopping, drug stores, chademo is really quite prevalent). I had done (and paid for) the EA sessions just to see how fast the car could charge with the faster Chademos. That answer was 20 minutes from 11 to 50% on dash SoC. 50% dash is like 55-56 on LS and will get you over 100 miles at moderate highway speeds. Or 9 to 71 in 35 minutes (36+ KW delivered).

I am looking to see if I can exceed 80 kW/h in optimal conditions and a SOC < 10%. My record so far is 76 KW

There is minimal evidence that DC charging quickens degradation. Its all about SOC and heat. Keep those under control and you are fine. Interestingly enough, I just went thru a week where I drove 600 miles and then a week when I drove 161 miles. Both weeks saw the same amount of capacity loss. Have you ever had a large decrease in battery numbers happen overnight or within a few days. Like ¾ to 1% SOH?

I did do a 329 mile trip with 3 DCs and lost .05% which is very large compared to what I normally see but a few days later, I went 280 miles with 4 DCs and lost .01% which is the norm. Temp ranges on the battery were about the same.

I haven’t seen any big jumps yet,
But I am only checking once a month at this point. I am trying to keep SOC to 90 or less and bottom around 15-20%, minus high speed Chademo tests.

I have one of the first delivered 2018 SL in Chicagoland with 40kw battery
here are some of the problems I have encountered

1) Andoid auto was crashing then stopped working.
replaced head unit and usb port.
I gave up on it.

2) Clicking from front when accelerating from stop and initiating braking.
Took three service returns to get fixed, Finally drove with service guy, told them to keep the car if the cant fix. They used microphone and found an "axle click" apparently boot of axle loose. Perhaps because i drive car pretty hard!!!

3) bad tire sensor. And a tire that disintegrated

4) battery degradation greater than 2015 leaf.
HERE ARE MY STATS.

Can anyone comment how battery is doing?

It does look like your battery degradation has flattened significantly.

The 40kwh packs do seem to degrade faster than the Lizard packs in the 2015-2016 (24kwh) Leafs, at least so far.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Some of those 2015 Lizard packs have been mighty impressive, with SoH in 90s now 5 years later. That’s on par with Tesla packs.

Your battery is doing about the same as everyone elses. You would have had a much clearer picture if you had recorded stats at regular intervals but I will predict your rate of loss will drop to 1-2% per 10,000 miles.

The peculiar thing I see about all this is the lack of regional differences previous packs saw. Discounting Hellish extremes of Phoenix, previous packs degraded fairly close to the climate they lived in. Which is why a degradation chart was created. "Most" fell into a rather predictable pattern.

Well, that pattern has disappeared for "most" of us with the 40 kwh pack. Now nearly everyone falls into the same degradation pattern and rate.

The newer chemistries seem to favor warmer operation. You see this with Tesla’s as well with packs going above 50C by choice.

If even cold weather packs are moving to the low 90s SOH does that suggest that cold batteries no longer extend life? I would like to know if 2019 40 packs degrade on the same curve or not. The oldest ones are just at a year, so might be able to get some insight.

If you look at geotab 2016 Tesla S models, they also moved to about 90% SOH after 3 years, which is what we are seeing here with the 40 Leaf after 2 years.

Any 2018 40 Leafs our there with 95+% still?
