I have done 800 km drives in a day once a year in our 2014 24kWh Leaf, it ups the SOH about 10% and it stays high for many months. It works fine, it still have 12 bars after 10 years and 120.000 km. Living in cold climate in the north of Sweden.
@ a 2014 Leaf has no Rapidgate problem. After 3-5 charging stops the battery is 50+ celsius, but it drops about 5-10 celsius in about 10 minutes when you start driveing so it won’t be too hot at the next charge. As long as it is below 54 celcius it just charge faster, you can acctually get 49-50 kW charge speed. But the once 24 kWh battery is now just about 20 kWh, you can only drive some 30-40 minutes at about 100 km/h until you must charge again. In the end your average speed will be 50 km/h. 12 charge stops and 16+ hours.
FYI: This is how I destroyed my battery to get a free one from nissan when I was approaching my warranty limit with my 2012 leaf. I needed to drop 1 more bar to hit the replacement so I started running it hard, discharging it far, and quick charging frequently. It did a real number on the battery and I got my replacement!! I wouldn't suggest this unless you are trying to kill the battery on purpose
The warmer a battery gets the more capacity you get out of it. So naturally when you quick charge your car, sometimes multiple times and warm up the battery, the car thinks SOH went up a bit when it didnt. L1/2 it for a week and it will drop back to where it was.
I had a leaf from 2017 to 2021. I used leafspy trip log to monitor soh and I got it to go from 90% to 96% over a few months by taking it down to turtle mode once per month and then L2 charging to 100%. I also rapid charged it once per week. I did notice that during covid when I hardly used it the soh rapidly dropped down to 87%. The range didn’t change much so I just presumed it was just the bms display that was being impacted. I always used the leafspy soc to judge range and that never failed me.
Thanks for the info. The experience you had with SOH was what I was anticipating with this experiment. Maybe I didn't let the SOC go low enough? I never got down to the turtle. Thanks again for the comment.
The lowend calibration is best done; leave the car overnight ie 8 hrs with less than 20% battery but a warm night ie above 15°C... Bringing the level to lower levels alone is not enough... And that need be done twice a year Bestest from Istanbul
You need to look at Hx that indicates the potential for increasing or decreasing of SoH in while you drive. The SoH changes when there is not changing or discharging for some time. Today I have made some “Big” trip with my 2013 24kWh AZE0 about 300 km. I started with 74.15% SoH and 56.47% Hx I drove about 55 km. Was on 50% SoC and charged on L3 to 88% then drive another 72km my SoH was 74.20% Hx increase to 56.98% my SoC was 28% and charged to 100% on L1 with about 3.3kW (custom charger). Then drive another 72 km, SoH was the same 74.20%, Hx increase to 57.88%. SoC was about 45% and I L3 charged it to about 87% SoC and drive another 68 km and SoH was the same 74.20%, Hx increase a lot to 60.74% and my SoC was about 28% and I ones again L3 charged it to about 57% and. Drive another 28 km the SoH was 74.20%, Hx was increase a little bit more to 60.87% and SoC was 30%. I bet tomorrow my SoH will become at least 76%. The temperature of the battery is key for this to happen. I haven’t hammered it only about 5 times for not more than 5 km total.
This morning it was charged to 100% SoC the SoH was 76.20%, Hx was the same as in the evening 60.87%. Till the end of the day I made my daily commute and Hx decrease slowly but steadily to 60.25% and SoH is now 75.94%. Yesterday on every stop I was charging immediately and then drive back. Today my commute was 29 km, pause 4 km pause, 7 km pause, 5 km pause and 22 km and it was 44% SoC….
I bought my 2019 LEAF after it sat new on the dealers lot for almost a year and a half, it had under 200 km at time of purchase. The state of health was 95.x %, maybe time just degrades the battery or my theory was it sat fully charged for most of that period. Anyway now the state of health is 89 % at 77,000 km and the largest drop occurred when we drove way past the 0 percentage on dash, maybe around 5% the dash just showed two dashes and we still had about 20 km to a quick charger, maybe not that quick it is 25 kw unit in Flesherton Ontario. The charger was much appreciated as outside of the town the charging ops are few and far between. We received enough of a charge during lunch that we were confident in making it to Collingwood where there are many charging ops.
That car has been 'frozen' and BMS did not update it's degradation over the time period... it's known Leaf degrade fast over time, if they drive or not...
One word, Temperature … In summer my SOH is higher than in winter L3 ups the temperature … so it can hold more charge and the BMW tries to follow that …
You should look at your Hx. It's more important than SoH. Your Hx is at 60.88% which is quite low. Also your battery m/volts will change while you driving. So 14mv can jump to 30 or more.
For me(a potential used Leaf buyer) i find it rather disturbing that the battery SOH can be at 82%(ish) and the display still shows 12/12 bars 😓 100/12 = 8.3% per bar, so IMO it should show 9/12 left, when does it actually lose a bar?
I notice that you have all 12 battery capacity. Bars on the -, but your state of health is less than 85% state of helped I thought the - capacity bars. The first bar would be lost when you drop below 85%. Which my car has done. 2 years ago, but my car still has 83%. But I have lost that first bar. I know have only 11 bars.
I agree, under 85% SOH I have heard it will go down to 11 bars. But, I have noticed that when Leafs drop SOH it sometimes takes a month or two for the bar to disappear from the dashboard. I think this is because Nissan knows the SOH can bounce up or down and they make sure it is below 85% for the long term before actually removing the bar from the display. I had another Leaf that went from 11 to 10 bars after it was below (78% I think?) but it took a month or two before the bar actually disappeared from the dash.
I think You’re going to lose your first bar very soon 😢. Maybe take into consideration that your car BMS was reset and/or the odometer was rewritten before You had bought the car. Our 2016 LEAF has 107k km in it and has 1700ish L1/L2 charges. Timed charging counts two L1/L2 charges and we had some… I think too much charges for 9000…
Im like half way into the video and getting frustrated as you keep skipping the quick charge.. thought this was the whole idea of the video and the experiment.. 😊?

Interesting. 800 km in one day means you have to do lots of DCFC. how about temperature of the battery?

Thanks that's a good idea I need to pay more attention to the Hx. I should go back and see how the Hx changed throughout this experiment.
This morning it was charged to 100% SoC the SoH was 76.20%, Hx was the same as in the evening 60.87%. Till the end of the day I made my daily commute and Hx decrease slowly but steadily to 60.25% and SoH is now 75.94%. Yesterday on every stop I was charging immediately and then drive back.

Not sure that would work on my 2015 Leaf that has 78,000 miles. Yours has just not been used much.
You should look at your Hx. It's more important than SoH. Your Hx is at 60.88% which is quite low. Also your battery m/volts will change while you driving. So 14mv can jump to 30 or more.
Laughs with an HX of 32
If one has time-say over a couple of days- maybe a weekend. Using a slow charge 110 volts at 12 amps,, one can get 315 mile range at 95 % charge.
For me(a potential used Leaf buyer) i find it rather disturbing that the battery SOH can be at 82%(ish) and the display still shows 12/12 bars 😓
100/12 = 8.3% per bar, so IMO it should show 9/12 left, when does it actually lose a bar?
Search on Google what % meaning each bar. Is not mathematic
The first bar is 15%, the others 6.25% each
I notice that you have all 12 battery capacity. Bars on the -, but your state of health is less than 85% state of helped I thought the - capacity bars. The first bar would be lost when you drop below 85%. Which my car has done. 2 years ago, but my car still has 83%. But I have lost that first bar. I know have only 11 bars.

I had another Leaf that went from 11 to 10 bars after it was below (78% I think?) but it took a month or two before the bar actually disappeared from the dash.

See how it goes.
I think You’re going to lose your first bar very soon 😢.
Maybe take into consideration that your car BMS was reset and/or the odometer was rewritten before You had bought the car.

I think too much charges for 9000…
Im like half way into the video and getting frustrated as you keep skipping the quick charge.. thought this was the whole idea of the video and the experiment.. 😊?
