But that doesn't mean that some implementations of the old specification didn't fudge a bit or that some of the implementations were fully compliant but were done in such a way that was never conceived of by the standards committee.
I should add that is is also very possible that Nissan has a problem with their implementation of the CHAdeMO specification in the 2018 LEAF.

From LEAFer in Quebec

"I got the same issue on the 2018 LEAF SL Demo unit we got from the dealer at Quebec city yesterday,
I tried many times on both blue DCFC charging stations (Flo and ElectricCircuit) but nothing happen.
400V DCFC charging station can't start charging the 2018 LEAF Demo unit."

My 2018 does not charge on AV DCFC. It fails during voltage test. Works on other DCFCs so wondering if anyone else has seen this?

*scraping plans to test car on Greenlots*

Greenlots was the company that managed the charger, the guy at Greenlots said that Signet was the manufacturer of the charger.
 
DaveinOlyWA said:
Greenlots apparently uses all kinds of hardware as they are primarily a "charge management" company so it would be essential at this point to determine what brand of charger was used.

I can confirm we now have several reports that Aeroenvironment DCFCs will NOT work.

In not so unrelated news. Aeroenvironment received a 2018 LEAF to test yesterday (soooo, "now" is a good time??)

Greenlots said the charger was made by Signet.

Sorry 6kW not 6kV. Would 6kV at 1 amp kill the Leaf?
Probably. J1772 inlet is supposed to have 240 volt input max. CHAdeMO input is about 400 volts.

Leaf battery pack operates around the mid to high 300 volt range.

Was the car still On when you tried to start charging?
sh

I believe it was not on. Certainly not intentionally. But it shouldn't matter. These things need to be idiot proof if they are going to be a mainstream mode of transportation. Anyone could forget to push the stop button.
I agree. It shouldn't matter whether the car was on or not.

Prior to model year '18, if you tried CHAdeMO charging with the car turned on first, it simply wouldn't work. It was easy to do that on the '11 and '12 due to the mechanical charging door release w/no interlock. On the '13 to '17, since you have to push a button, the opener button does nothing when the car's in READY mode. It must be turned off to release.

OP, willing to post a Plugshare link to the CHAdeMO charger you used? It'd be interesting to know the model and whether anyone else had trouble w/that unit.

Thanks! Yours is by far the worst case. Yes, I've heard of Signet and seen them on Plugshare before. Per, https://www.chademo.com/portfolios/signet-charger-09/, they're apparently a Korean company.

Will be interesting to know if charger or car is to blame or some of both.

Prior to this, about the only time I'd heard of the "magic smoke" (http://www.catb.org/jargon/html/M/magic-smoke.html) being let out of CHAdeMO chargers was from not very reliable tall slim Nissan/Sumitomo DC FCs after extended sustained output connected to a Model S (https://teslamotorsclub.com/tmc/threads/japan.15586/page-11#post-772913 connected to https://web.archive.org/web/20150214040724/http://www.nissanqc.com).

It will be interesting to find out what caused this.

But right now I really feel like I'm more interested in how I am going to get a replacement car. I did really like my Leaf for the brief week and a half and maybe 600 miles or so that I got to drive it.

thanks for the info. It will be invaluable for resolving the issues. We already have SEVERAL confirmed issues with Aeroenvironment chargers here in the Pacific Northwest so starting to look like its on Nissan right now.


Now I just got a charger error message so my LEAF is fine and yeah, its a HUGE improvement over my 30 kwh LEAF. LOVING that E Pedal!

Yep, really loved that e-pedal.

Thanks! I noticed on Feb 21, 2018 (two days before your post) a report on Plugshare of
Scott
Nissan LEAF
CHAdeMO not working. Error message is faulty ground.
Yes, that was the day of my mishap. That was apparently posted after the mishap. I tried to report the machine malfunction at the time, but plugshare was not allowing me to for some reason. So I left unreported. But I did not see that report at the time.

Friday the 23rd was when I heard back from the dealer that my car was, as the tech said it, generating literally pages of error codes for every system in the car. Up to that point I was hoping, expecting really, that it needed a simple reset, or maybe had fried a fusable link, and would be back good as new.

Then I went looking here to see if other people were having similar issues and to let people know this is a possible issue.

I managed to smoke a Nissan DBT/CEV rapid charger with a 2014 LEAF. This is the same design but built in France by DBT/CEV. I was the third car in line and the rapid overheated. My car was fine. The charger wasn't.

DBT/CEV and the operator went through and retrofitted all the chargers to improve cooling, reduce water ingress and set a 106A current limit. Since then they've been more reliable.

We had several chargers that had overheating problems as well and iirc were fixed by simply maintaining filters better and repositioning the existing fans with additional venting to better direct air flow.

Any update?
No update yet. Nissan sent someone "from the factory" to look at the car earlier this week. And I have been interviewed twice by Nissan customer service asking what happened. They have lots of questions for me but nothing about how or why they think this might have happened or what they plan to do.

I will update if/when I get more info. Meanwhile I have a loaner 2016 Leaf from the dealer.

That really sucks that they have you driving an older loaner. Please keep us updated on your situation. I have to use ChaDemo (trying to stick to lower rated machines like 20kW to 40kW) almost exclusively for the next month, so I'd be interested to see if there's something I need to watch out for.

The dealer sevice manager says the people at the factory are really interested in my car because no one has ever seen this before. The folks at Greenlots said the same, that this is the first they have seen. Service guy says there was no change to the CHAdeMO port, it is the same hardware and software as earlier models. So hopefully this was a one in a million fluke, the stars and moon alligned just right, and not an issue with the new Leaf.

30 day lemon law deadline is approaching. Be sure to read the guidelines

As I understand, it is not a 30 day deadline, it is that I have to give them 30 days to make it right before I can invoke the lemon law and demand replacement or refund. Maybe I misunderstood.

I talked to AV tech who was doing general maintenance on Tumwater Station yesterday and they know what the issue is concerning the 2018 LEAFs but would not elaborate. It would appear that AV is in wait mode in its collaboration with Nissan on how to proceed.
