I'm making a 500 mile round trip drive over Memorial Day weekend, Dallas to Southwest of Austin and will need 3 or 4 DCFCs, in my 2019 SL Plus. My first chadmo fast charge to test the car wasn't great. I got 72 KW for less than a minute and within 5 minutes it was delivering mid-30 KW. Another member commented that I chose a bad fast charge network (EVgo).

I'll take the trip opportunity to document my charging experience. What data points would you like to see - ambient temperature, state of charge, charging network, battery temp, total kilowatt hours?
It looks like the trip has the following DC chargers on the way:

EA at the WMT Bellmead Center, One 50 kW Chademo
Round Rock Premium Outlets, One 50 kW Chademo
Cinemark at Round Rock Premium Outlets, One 50 kW Chademo, EVgo
Round Rock Nissan, One 50 kW Chademo
Round Rock Hyundai, One 62 kW Chademo
 
Where is the battery temperature graph? The pack could be hot.
Here is the battery temp.
The picture of the charger screen with 48% was taken at 2:34 PM. The battery temperature below was taken after the charging was started, this caused the battery to warm up and for the rate to drop. My average charging rate for this session was less than 50 kW.
This was a very standard use case where I needed to charge my car on a long distance trip after driving about 120 miles during a cool rainy fall day with ambient temperatures at 51 as you can see.
This is the main point. DC fast charging is intended to be used during long trips. This is the standard use case. So, if the Nissan Leaf battery is unable to charge optimally during such a standard use case, then 100 kW charging is mis-guiding at best and not achievable in a standard use case for certain.

So it took 14 minutes to raise it to 67%, how much longer did it take for the needed charge (13%) to get up to 80% SoC--Was it more than 31 minutes?

If the kW never got above 50 kW, the QC station is coded for 50 kW, even if it supports 100 kW. It's odd that many QC stations that are rated for 50 kW, struggle to make 50 kW when plugged into a Leaf with a low enough SOC, Temperature, etc. EA stations are a good example, rated for 50 kW but only top out at +44 kW for example. When I did my QC station comparison some years back, QC stations that were only miles apart would struggle to make +45 kW when under identical conditions, another QC jumps up to +70 kW right away, etc.

I got the same experience with EVgo Charging Stations that Nissan partners with, supports and touts.

Let's look at it from another direction. If the Nissan Leaf Plus with 62 kWh battery supports 100 kW charging, why doesn't the Nissan Leaf User Interface only go up to 50 kW charging rate? Do you all have the same info on your screens?

The same reason when less than 5 minutes remains on the 25,50,75 marks when charging that is just stops at 5 minutes, Nissan didn't want to code an interface for all the different types, just took one common one (for the 2018 I suspect) and just apply it across all models. :unsure:

In the time that I have recorded and documented, the battery received 11 kWh in 14 minutes. This translates to a charging rate of 47 kW. A rate that is achievable with 50 kW chargers. That is why I assert that the 100 kW mention and listing in the manual including the chart on page CH-8 of the owner's manual is at the least mid-guiding and certainly not achievable.
The Nissan Leaf owners are mis-guided with the semblance of being able to achieve faster charging rates with 100 kW chargers than 50 kW chargers and that turns out to be unachievable.
Here is what Car and Driver stated when they tested the Leaf:

The Nissan Leaf makes two appearances on this list but not for good reasons. The 2021 Leaf Plus, which Nissan says can charge at a higher 100-kW peak rate versus the non-Plus that's capped at 50 kilowatts, only managed to reach 52 kW during our test. With its 62.0-kWh battery, Nissan's EV hatch needed about an hour to charge from 10 to 90 percent.

I can hear the "support Nissan against the numbers" crowd claiming that Nissan never claimed that the Leaf can charge at 100 kW. While that may be true, it was suggested to mis-guide. A suggestion that Car and Driver interpreted as "Nissan says can charge at a higher 100-kW peak rate". This is how a reasonable person would interpret that mention. In addition, even when we accept the CH-8 chart which shows rates lower than 100 kW, those are not achievable either. In the end, the Nissan Leaf Plus driver gains no advantage from the 100 kW charging. It is equivalent to 50 kW charging.

Would you be able to drive down to less than 20%, then check that menu and scroll down to see if the 100kW option gets revealed?

And if it does, then try charging at a 100kW station?

If you have a 62kwh pack model (Plus), then it seems that you should be able to, and it should charge faster than at a 50kwh station.

It would be nice if Nissan could answer that question. They built the car, they verified the specs they published (that's an ISO requirement), just publish the test results so we all don't have to go drive around testing this and that.
 
Do you really want to charge at 100 KW with an aircooled battery pack?
You hit it right on the head Joe. Why did Nissan even bother to refer to the 100 kW charging for a battery that is air cooled? This is except to mis-guide. The 100 kW mention is a joke. Reputable car companies don't play such games.

Can you all go to the Charge Time Screen in Settings and let me and the others know whether you see 100 kW listed on that screen?
You can find this screen by going to:
- Settings
- Scroll Down to EV Settings
- Scroll Down to Charge Time Screen and select it

I am trying to determine whether that is an issue with my car or if it's that way on all Leaf's with 62 kWh batteries.
I appreciate all of your responses.

A new EA site here in CA also has apparently 0 CHAdeMO.
https://www.plugshare.com/location/552490 from the pics and listing has 0 CHAdeMO. It doesn't sound like the best place to be at night and I'm usually busy during the day. (I personally know Taycan driver StealthEV who commented.) I will swing by one of these days.
At another EA site (also in CA) where they originally left the old CCS1 + CHAdeMO DC FC in place after upgrading the rest to single cable CCS1 dispensers, they removed that dual handle unit. It is a single next gen CCS1 dispenser in its place now, leaving that site w/0 CHAdeMO.
https://www.plugshare.com/location/247356 is the site in question. You can see from the older pics, there was CCS + CHAdeMO unit next to the B of A building but it is no more. It's a next gen CCS1 only unit now. The rest of the units there are also single CCS1 dispensers + 1 J1772 EVSE.

has a guy who has hit 71 and 72 kW on his Leaf using a CCS1 to CHAdeMO adapter.

Re: my statement of Leaf being on life support in the US, look for Leaf on the last pages of these:
https://www.coxautoinc.com/wp-conte...y-Blue-Book-Electric-Vehicle-Sales-Report.pdf (from https://www.coxautoinc.com/market-insights/q1-2024-ev-sales/)
https://www.coxautoinc.com/wp-conte...y-Blue-Book-Electric-Vehicle-Sales-Report.pdf (from https://www.coxautoinc.com/market-insights/q4-2023-ev-sales/)
Other than Leaf and Teslas, every single BEV sold as new listed there has a CCS1 inlet. Even Nissan went with CCS w/Ariya for North America. The only other consumer BEVs in the US sold/leased as new that had CHAdeMO were the gen 1 Kia Soul EV and Mitsubishi i-MiEV, both discontinued years ago. US never got gen 2 Soul EV, which was CCS1 for Canada.

You can also check Nissan numbers against these:

https://usa.nissannews.com/en-US/releases/nissan-group-reports-2024-first-quarter-us-sales

Click on Automaker at https://evstation.com/tesla-nacs-charger-adoption-tracker/ to see that virtually every automaker selling or will sell (sometimes again) consumer BEVs in the US has jumped onboard NACS (https://www.tesla.com/NACS). Even Nissan jumped on the NACS bandwagon: https://usa.nissannews.com/en-US/re...-standard-nacs-for-ariya-and-future-ev-models. About the only one I can think of that isn't there is Vinfast.

ramisalah, from everything I and others have wrote, do you understand why we're puzzled in why you're wasting time and energy on this? It's pointless. I don't think you'll hit better than low to mid-70s kW, assuming you can even find many >50 or >62.5 kW CHAdeMO.

I think the Leaf and its aircooled battery is a fine car - for certain use profiles. It excels at anything that can get done with L1 and L2 charging. Even a single L3 charge of perhaps 50KW -occasionally- isn't the end of the world. So with a Plus - that's a potential 200 mile radius of homebase. Or ~400 miles with one fast charge today and another fast charge on the return trip. That's pretty good for most people.

For the ambitious EV roadtrippers - buy something else.

The purpose of this post is to review the Nissan Leaf's ability to reach the mentioned 100 kW rate or even the 0-80% in 45 minutes. In my experience, even with a 100 kW charger, my charging times are not any better than charging with a 50 kW charger. I posted the question regarding the lack of a 100 kW listing on the Charge Time Screen in settings. If other owners of the Plus have 100 kW listed and mine does not, that may indicate that my car has an issue. Can you check your settings?
 
Here's the charging screen from my 2019 SL plus. The vehicle control system was updated by Nissan a week ago, so it has the latest software for the US market. Top charging speed is 50 KW quick charge.

This is really starting to look like the smoking gun that Nissan included 100 kW to misguide the consumer and the Leaf charging time is the same as the 50 kW charging in real life use cases.

That's very vague. Who mentioned 100kW rate? If it's Nissan, please back it up. If it's not from Nissan then it's not an official statement and that source is whom you need to go after.

Have you considered the possibility that your Leaf is broken or malfunctioning? 4 or 5 of us have mentioned or shown you 70kW charging, so there's enough evidence that it can and is being done. These 4 or 5 people don't have special Leafs likely any different than yours.
