Any updates on CCS1?

[DavidBurbidge]

Does using the adapter affect charging speed?

Does using the adapter affect battery health differently than CHAdeMO charging?

I did a bunch of testing today at a supercharger (non-matic dock) with various software versions on my A2Z adapter.

None of them worked.
I'm at a V4 supercharger. These were just recently installed in the last few months.

I had my A2Z CCS1 to CHAdeMO adapter and a NACS to CCS1 adapter I borrowed from a friend.

In the app, I identified the car correctly as a Leaf.
My understanding is that the superchargers do exchange VIN information.

I tried the original version of software that was on my adapter.

I tried the other version that came via the email.

And lastly I tried the version that I downloaded from the A2Z update site.

I have the logs from all these sessions.

Each time the first blue charging light on the leaf would briefly come on. But then the session would air out.

I also tried some variations on what adapter I plugged in when, and when I turned on power to the A2Z adapter. No dice.

EDIT: I tried this at another CCS station today and it worked fine.

Next I'd like to go back to the magic dock supercharger and try different versions of the software. My understanding is that theoretically the magic dock superchargers should not have any manufacturer or vehicle model restrictions on them.

My adapter has the latest version of the A2Z software running on it. The one downloaded from the official site.

In the Tesla app, I had my car correctly identified as a 2015 Leaf. I chose the option stating that I did not have a NACS adapter. (That way it would use the magic dock's built in NACS to CCS adapter).

I tried it at the Magic Dock Supercharger today and... SUCCESS!

I also did a few variations that all worked.
- identify my car as a Chevy Bolt. It worked!
- identify my car as a Leaf with a NACS to CCS adapter. Then using my own NACS to CCS adapter plugged into the NACS hose of the magic dock dispenser. It worked!
- changed to the software version that @Shockazulu identified in his post. It worked!

I switched back to the software from the A2Z update site.

After this, I went over to a non-magic dock supercharger. It's very new cabinet; a V4. Tried all sorts of variations of software on the A2Z adapter, cars in the app, and even brought my own NACS to CCS adapter into the mix. No dice.

So at least for me, running the official software from the A2Z update site, I can charge my car at a Magic Dock Supercharger. But not at standard Superchargers.

They are not many superchargers that are Magic Dock superchargers.

To find ones near you, use the Tesla app. When you load in your car profile, click on NO in the profile where it asks about whether your car has a NACS adapter. That way the available chargers will be filtered to only show the magic dock locations.

Does using the adapter affect charging speed?

No differently than using CHAdeMO unless CCS is rated for more power than CHAdeMO and it could be faster. I wouldn't expect CCS to support less power than CHAdeMO.

Does using the adapter affect battery health differently than CHAdeMO charging?

No

CCS using an adapter has been faster in my experience. Charge can be as fast as 73kW, so there is faster heating of the battery.

And for those asking, how rare are magic dock superchargers? Where I am in the upper Midwest:
Wisconsin 1
Michigan 2
Illinois 1
Iowa 1

So while it is helpful for where I am, it isn't full access to Superchargers.

I sent my feedback/experiences to A2Z.
I included log files as well, so hopefully that helps them tweak and update the software if possible.

No

Thank you!!

Thank you Eric Powers for sharing your very helpful results with the A2Z adapter. I wish I lived in Wisconsin to rely on your expert services

Are there any range-anxious Leaf owners in Phoenix Arizona area that are interested in the A2Z CCS to CHAdeMO adapter? I have one too many. We could go to an area CCS charger, and possibly demonstrate my extra unit. It would probably work for the CHAdeMO Kia, too?

 

[EVPowers]

Just an FYI, I tried to see if I could charge on older superchargers, like some of the version 2 superchargers in my city.

I couldn't even test it out on these because there's no way to choose them in the app. Therefore you can't activate them for a charging session. That's what I assumed I would find, but thought I should mention it anyway.

The only superchargeres Tesla is allowing non-Tesla EVs to charge at are the Version 3 and Version 4 superchargers.

And as I noted above, today with the A2Z adapter I cannot get it to work on the supercharger network unless it is a magic dock supercharger. (Which are few and far between in most areas of the US.)

Additionally I contacted a consumer who had gotten there adapter working on a Tesla supercharger (different manufacturer, not A2Z). Although he got it to work a few months ago, he hasn't retested it since.

He does not have any plans to retest it anytime soon.

Speculation is that Tessa may have closed the loophole that previously allowed him to charge. So even though it worked previously it may not work now.

Unless you are in Europe, where most Tesla chargers allow any EV.

CCS using an adapter has been faster in my experience. Charge can be as fast as 73kW, so there is faster heating of the battery.

On my 2024 Nissan Leaf SV Plus at a CHAdeMO charging station I have seen a 76 kW charge rate. Using my ElectWay CCS1 to CHAdeMO 250 A adapter I have only seen the same maximum charge rate at various CCS1 charging stations ( Electrify America, Apple Green). Adding my A2Z NACS too CCS1 pro adapter to this I have been able to charge at the same 76 kW charge rate. I wonder, if only the Nissan Factory chargers in TN, are the only ones capable of charging at 100 kW and under what battery conditions. Nissan shows 480 V charging voltage on thier web site. Maybe that is the reason others have only seen 76 kW maximum charging rates with their Leaf’s.

 

[DougWantsALeaf]

That's interesting as Leaf pack voltage is lower than 480.

 

[Shockazulu]

I received another email from A2Z with a update file.
I'll post the file when I get home since I learned the last time I posted the update file, I need to zip the file in order to post it here.


Hi there,

Attached is the latest firmware. Follow page 7-8 in the manual for the steps.

Logs :
- This software update fixes compatibility issues with DC chargers.

Thank you and have a great day.

 

[BillAinCT]

This is the same firmware file sent in an email on December 23, 2024.

 

[Shockazulu]

I think it's different.
They are all named the same thing.
We have 3 different ones now I believe.
3 files with 3 different dates.
Nov 8th 2024
Feb 1st 2025
Feb 28th 3025

 

[EVPowers]

Sure would be nice to be able to track versions.

Looking forward to seeing if the Feb 28 version (re)gains access to standard Superchargers in the US.

All my emails to A2Z have gone unanswered. My last email was on February 5th. I included session log details in case it would be helpful to them.

@Shockazulu , If I get the file today I may be able try it. Otherwise I'll have to wait a few weeks before I'll have access to my Leaf again.

I am good with 76 kW, even though faster would help on trips. However, it is nice to take 45 minute breaks on long road trips. Safety, first!

Here is the newest file.
I had to figure out how to do using my phone.

Hoping you can test at a Tesla charger.
I attached the file to the post above.
Do you already have a NACS to CCS1 adapter?
