BRAVO! You would find a large market in the US if you provided this for all the CHAdeMO vehicles left abandoned by the standardization to CCS.
Incredible! Against all odds and the overcomplicated protocol.
Yes, CHAdeMO: some 100 lines of code. CCS: many 10000 lines of code
Chademo state machine is a "mess", but the CCS multi layer protocol is even horribler 😂
One small step for man, one giant leap for mankind.
Seriously, I think this is an achievement as great as the moon landing.
Good work!!!
Amazing to finally see it can be done. Hopefully some day there will be a commercial adapter solution available for us Leaf drivers. Good job!
Thanks 🙂 next up is a single board controller which will further facilitate this
Best of luck with it. I'd buy one. I have a leaf.
Amazing to see people trying to solve real-world issues. I'll keep a look out for updates, well done!
thanks🙂
I would probably buy one of these for my LEAF in the US, if it's in the sub-$1000 range. This would make roadtripping so much easier and more comfortable!
I bought a new LEAF in 2022. I would buy one in the sub $2K range. Just sayin’
Please manufacture this asap! In the US we have lots of CHAdMO only cars but many more CSS chargers :(
I think the leaf is the only car left using CHAdeMO and those arn't great on fast chargers do to the air cooled batteries. Wish they would sunset CHAdeMO and just have CCS as the standard world wide.
@@winningfreak1 To be honest I wish they would sunset CCS and just have CHAdeMO with greater current capability. But of course that's not in sight.
This project demonstrates the ridiculous complexity of CCS (many 10,000s lines of code) over CHAdeMO (about 100 lines)
@@EngineersFear Interesting to know about the code! I thought Chademo was more complicated since it has more connecting wires.
@@winningfreak1 My Mitsubishi Outlander PHEV also uses CHAdeMO. Fortunately I can also use gas to charge, but it's nice to have the option to DC fast charge when gas is pricey.
If this can be reliably done, would be the best for all the older leafs and env200. Muxsan has a ccs conversion for 3500 eur, the bmw i3 LIM conversion is doable for less then 1000 euro but with way too much time, but this seems a lot cheaper. Will have to check out the forums once i've found the time. I'd be very happy if i can charge with chademo speeds on a ccs charger.
Oh, very _VERY_ nice job!
This is awesome. Looking forward to seeing this made into a robust kit. Keen to buy
Check the openinverter shop :)
Looks amazing, well done to you and the others for this big step forward. If I ever get Chademo working I'll be looking into this. 😁
I needed a device like this so badly last year when I used my 2013 Nissan LEAF for a 150 mile trip every month. It worked fine with Chademo, but the chargers were broken most of the time. CCS was available. but not for me. Of course, Tesla has their own Chademo adapter, but in the reverse direction, so should be possible to do NACS to Chademo, now that the spec is open.
Your battery gonna die fast
@@user-ce5wo3tb5o I fast charge the LEAF maybe one trip a year. Last year it was one 150m trip per month, but that is done. The battery is still at 85% SOH since I keep it between 30-80% on slow charging as a daily driver. Not bad for a 2013 LEAF with 70K. I had to stop using it recently because a ball joint failed.
Well done. That's awesome!👍
Fantastic video. Looks to be a comms bridge, I wish you all the luck in development in the future.
Thanks 🙂
Yes essentially it translates CCS to CAN
I really hope that you can make a success of this commercially. This misbecoming even more important as the new charging stations are not including CHADEMO. Give us an update soon please
Das ist die Rettung für meinen alten Nissan leaf.
Ich hoffe ich bekomme das Ding auch selber gebaut.
That's awesome! Nice work
Amazing! And they said it couldn't be done! Make and adapter that's reliable and I'll buy one.
Super spektakulärer start im Video. Tolle Arbeit weiter so.
Danke 🙂
more info please.. glad to be a BETA tester for US market.
Awsome 🎉👍👍👍🤩 project. Well Done
You are the GOAT
Very very good.
Another vote to sell this ccs to chademo adapter in your webstore
got no trouble selling a board you just need to find a CCS socket and CHAdeMO plug somewhere. Maybe 3D print it
Hello Johannes, Nice work! 👍
You mention that this does not work with an ordinary CHAdeMO vehicle. Can you explain in detail? Thanks!
Yes, as opposed to CHAdeMO CCS first precharges the charger output then closes the cars port relays. Therefor CCS communicates the momentary battery voltage to the charger which CHAdeMO does not.
Since my CHAdeMO is implemented in my VCU I just changed it to include the battery voltage. An ordinary Nissan won't do that.
now to have CHAdeMO work with the TESLA Supercharger network
The Tesla network is electrically CCS so it should be feasible
This will only work if Tesla allows non-Tesla vehicles to charge. Despite using Type2/CCS2 on their destination/super chargers they implement an additional check to make sure the vehicle is a Tesla.
They are slowly opening up their network to non-Teslas in Australia at least
"" This will only work if Tesla allows non-Tesla vehicles to charge" They already do, so I am missing your point.
@@markyormark7747 so far it's very limited. They rolled out magic dock to two states in the US as the US (still) has no federally mandated plug type, but seemingly instead of expanding that Tesla has instead started to work out deals with other automakers to let them use the Tesla connector, however none of these models are out yet. As of rn Tesla's network being open is a mostly "on paper only" sort of thing, not in practical terms yet.
I know.@@cpufreak101
There is an ukrainian group, who also got working CCS charging to Chademo. But it is different. They converted a chinese BYD Yuan from GB/T to Chademo. With an adapter they can charge CCS over the Chademo port. -> th-cam.com/video/9zTyD0ttzQo/w-d-xo.html
Pretty slick device!
Do you reckon it would work on an unmodified Leaf? They must get the 12V from somewhere
@@EngineersFear We do it for Chinese cars, Nissan Leaf is slowly dying.
But it will work on cars that have 12V on pin 3.
If not, then you need to add it from a 12V battery!)))
P.S. I am the developer of this device.
@@EngineersFear You have a cool project, good luck!
I've seen your video. Is your adapter something that will be on the market in the future? @@FastChargeIsFuture
Is it commercially launched. Can you pls share the manufacturer's details
Hello, I also need this controller, socket, cables and plugs. I can buy it in Poland. Is this board already on sale?
Not yet, the new board is still being tested and software must be completely ported to STM32
This would sell like butter to all leaf owners in EU lol
and in Canada
Hallo Johannes, verkaufst du schon fertigen Adapter ccs/chademo? Zweite Frage:" kann man die Leistung von 80kw motor von azeo erhöhen?"
Danke.
nee, werde ich auch nicht. Schau mal ein paar Videos weiter oben. 2. man kann, such mal nach Dalas EV repair
Danke für die Anwort.
I just need to know how much $ £€ Gold, Blank Check IDC I just want and need that adapter, even in its current state to work over here on CC1 in the US for my CHAdeMO LEAF ASAP! This would open up so many additional charge points critical to getting me and my hot degrading battery home! I'd buy one today if I could! Please let me know if you intend to sell these. I couldn't care less how janky it looks or if wires are hanging out or if the CHAdeMO handle is 3D printed even if it's held together with chewing gum, as long as I can CCS charge my LEAF I'll take it, today!
Money won't help ;) you'll have to visit above links and cobble one together yourself - it's not so hard (I think 😀)
I SWEAR TO GOD I WOULD PAY EVERYTHING FOR THAT ADAPTER 😭😭😭😭
well done
what car is that
The Touran
Do You or Damian plan to make video how to build this adapter in DIY ?
Not now. The implementation is at a very early stage with the linux computer. Once we've designed a bespoke board a tutorial would be relevant. If you want to chime in now, you've got to collect the infos from the links below
Tolle Arbeit 👍🏻 So eine Lösung für einen Nissan Leaf wäre Gold wert 🙏🏻 aber scheint nicht absehbar zu sein, dass sowas marktfähig wird, oder?
Schwierig. Mit so einem 3D-Druck Stecker würde ich nicht dauerhaft hohe Leistung fahren. Original Stecker sind kaum zu bekommen und wenn sehr teuer.
Für mich war das nur eine Art, die CCS Implementierung zu testen. Den Touran werde ich einfach umrüsten.
Is there any way we can get a walk through of the board and wiring so that those like me can try and work on something that would work for us I know there are lots of parts list and vague directions but love a walk through on the board build. And also would this application work for Fast chargers or just level 2?? It anyone could please reach out to me with the program he is using cause I love to download it and start trying to make this for my 2022 leaf as I don’t want to lose my fast charger when the CCS becomes standard
This is still work in progress and it would make little sense to explain some preliminary setup. I will follow up on this with the new single board solution that is currently being tested. Search the OI forum for QCA7000 to find out more.
You could sell thousands of these in the US, our CHAdeMO network is falling apart and not being replaced, we are desperate.
Hallo, ich hatte schon länger die Idee irgendwie einen "Adapter" zu bauen, welcher es mir ermöglicht, meinen Kia Soul EV mit CCS zu laden, da ich nur einen CHAdeMO Anschluss habe.
Könntest du mir vielleicht irgendwie weiterhelfen?
Schau mal hier: openinverter.org/forum/viewtopic.php?t=2262
Can we start a gofundme to commercialize this set up?
Thanks for the positive feedback :)
The adapter will be pricey unless you resort to 3D-printed parts because CHAdeMO plugs are super expensive. I think it would be easier to develop a retrofit CCS kit for CHAdeMO cars. That said I'm not really the right guy for product development.
@@EngineersFear well worth 1000€+ if you could replace the j1772/meinikes with a ccs 1/2 ...in addition to the chademo.
Sehr gute Arbeit! Wenn ich unterstützen kann würde ich mich sehr freuen. Viele Grüße aus dem Süden von Deutschland
Danke :)
Die beste Unterstützung wäre einen zu bauen und zu testen openinverter.org/forum/viewtopic.php?t=2262
Hallo Johannes, würde ich sehr gerne sofort machen. Komme aber im Forum nicht zurecht, welche Bauteile ich genau kaufen muss und bezüglich der Software.
Test kann ich an Alpis sowie Siemens und ABB machen. Mit etwas Glück kann ich Logfiles der HPCs bekommen und Stationsseitig zu schauen.
This looks complicated 😕
It will become simpler :)
I wish I was smart 😅
You don't need to be smart if you are charming or beautiful.
