Hi. Software updates for grey import Leafs. Does anyone know of any Nissan dealers who update imports with the latest software? It would help with rapidgate on the 40kwh ZE1 Leafs, and I believe some of the 62kwh ZE1's have a fault where they will not charge from 350kw Tritium Chargers (But work fine with the 50kw ones). Apparently this can be fixed with a software update? At the very least, it would be great to have the cars running the latest software available.

... any Nissan dealers who update imports with the latest software? My understanding is that Nissan won't touch a grey imported vehicle under any circumstances. It's a strange business practice. I would think that business is business, why not support them and take the money? I think that's one of the downsides to grey imports; you get no support at all from the manufacturer.

Maybe aftermarket companies like EVs Enhanced can assist. They mention various Firmware update services on their website. They're based in NZ, but iirc they started offering some services in Australia a few years ago. I had asked them about their software update for my 30kWh Leaf. evsenhanced.com/services/

I met the owner of a 4 month old Aussie 62 kWh ZE1 at a charger on Sunday and it would only charge on the 50 kW chargers.

It'd be good to know if his would charge on the 350kw Evie chargers which would indicate a Chargefox problem perhaps

It makes no sense to me either. It's a largish number of vehicles out there that they could be of benefit to (Help build goodwill) and make a profit out of.

The techs at Evie seem to be genuinely interested in fixing charger issues. They're hampered by the charger manufacturers, of course, but they have way better connections to them than we do. Evie have offices in Brisbane as well as Sydney, I believe.
I volunteered my 2012 Leaf for dual cable firmware testing recently. It was a fun night, and I learned a lot. I've told them I'm available for more testing. There may be chargers at Browns Plains and Lakewood soon, from poor memory.
Chargefox don't seem to be as proactive.

Yarrabilba was ok, but a bit of the way. I've always had good luck with Evie. Their Coochin Creek charger on the Sunshine Coast is perfectly placed. They're not cheap, but when you need them...

CHAdeMO is 50kW max. So unless the ZE1 use CCS, which I'm pretty sure they don't, it's not a software issue. I don't think that's right. The Tritium 350 kW chargers are limited to 200 A for CHAdeMO (and 500 A for CCS). So if a Leaf battery is at 400 V, and it's in good condition, it could in theory accept up to 400 V x 200 A = 80 kW. From memory, a Leaf battery is 96S, so 400 V would be 4.17 VPC, very nearly full, so they would not be able to take 200 A. But while a Leaf might be limited to very roughly 50 kW in practical terms, that's not a CHAdeMO limitation. If there was such a thing as a nominally 800 V vehicle with CHAdeMO, it might be able to pull well over 100 kW. For example, 700 V x 200 A = 140 kW. tritiumcharging.com/wp-content/uploads/2020/11/TRI105.DTA_.002_Veefil-PK350-Specifications.pdfEdit: At the very least, a Leaf should be able to charge at a 350 kW Tritium charger if it has a CHAdeMO connector. Most if not all Australian public chargers will have a CHAdeMO option, at least for some years to come. According to ev-database, it can charge at up to 100 kW.

Just to add another data point, I borrowed a Japanese imported Leaf e+ (62 kWh) a few months back, have charged it successfully at both Chargefox and Evie 350 kW sites (Tritium PK350 units). Peak speed was 72 kW from memory.

I don't think that's right. The Tritium 350 kW chargers are limited to 200 A for CHAdeMO (and 500 A for CCS). Good to know. A general Google search comes back with CHAdeMO being 50kW, but it looks like it's not technically correct. I wonder what Nissan specs say.

Only E+ Nissan LEAF models (62kWh) have the newer spec CHAdeMO that can go past 125A. The limitations are not from the charger manufacturer, they are CHAdeMO protocol specifications.
Units with 200A connectors will have the Sumitomo 200A connector (blue). When the CAN comms start, the car will advertise its version, and the station will apply a mask to the comms that suits that version. This is how it can communicate with iMiEV (oldest) and LEAF E+ (newest).
It is super rare for Nissan to update the charge controller firmware. I would suspect the manufacturer of the station will be implementing a workaround for some weird race condition depending on the version they are masking.
