I'm actually surprised how serious this adapter looks. The outer casing seams to be injection molded and someone has made a really good job packing everything in such a small form factor. As a designer I can say that someone has put a lot of hours and some money developing this thing. I hope we will soon see a video with someone charging a Leaf with it. This would be a real game changer for the Leaf. In Sweden where I live the ratio between CCS and CHAdeMO chargers is more then 10:1. I would definitely buy one.
Fortunately here in the UK there is provision for ChadeMo in most of the new charging hubs being built. Many networks recognise that early adopters still exist in quite large numbers.
I'd like to see the whole thing potted though once the design is more final... at 300V+ DC there is a substantial arcing potential to have that many parts that close together... especially since the contactor isn't breaking both positive and negative.
It will be a game changer for the LEAF and the Triplets if they can get a reliable CCS to ChaDeMo adapter, purely as they will now be able to access the entire network. In the UK, there are still ChaDeMo being installed, however give it 10 years and these cars will only be able to 7kW AC charge. When the Leaf 62 and UX 300e can get in excess of 200-250 miles, it may be less of a problem. However, for the Leaf 40 (and earlier), if the price is also right this will be a game changer. I believe Muxan will do a CCS conversion kit for around 3450 euro).
Agreed, I reckon they shortly close the charge port contactors in the car to sense the battery voltage. To avoid pack voltage on the CCS inlet they leave that one contactor open. With that sense phase done the car side contactors can do their thing fully separating pack and charger as appropriate.
Exactly. CCS and chademo have different protocols. On chademo you précharge the chargers' cap and it senses the voltage, whereas with CCS you communicate id
In CCS the EVSE sets the voltage and the EV measures it before closing its contactors. In Chademo it is the other way round, so you need to separate the two sides during the handshake phase.
Thank you for reporting on and researching of this topic, Dala. Everything I've observed so far indicates that any successful CCS-to-CHAdeMO adapter is probably going to be rather large. I'm concerned that attempting to fit all the necessary electronics into the confines of a handle-style block of plastic, like shown in the video, is not a good approach. It's going to weigh down on the car's receptacle and induce physical stress over time. I'd much rather see a design in the form of a briefcase or box that can rest on the ground and have a separate cable (~2m long) attached to it that's terminated on an ordinary CHAdeMO plug. In North America, it should have inlets for both CCS-1 and Tesla NACS. Europeans would probably be fine with just a CCS-2 inlet. I'd rather have an adapter that takes up some physical space, has some real world electronic flexibility and durability and actually works . . . unlike the "convenient" one built into a handle that doesn't!
"It's going to weigh down on the car's receptacle and induce physical stress over time. " - The question is, is that something the connector cannot handle? Because there are some really heavy CHADeMO connectors + cable out there. Most CCS are not as heavy.
In Amerika we don't need Chademo-> CCS1 adapter anymore, because NACS takes over everything. Is there a chance to get a Chademo-> NACS adapter instead?
Wow... I would want it tested at a Electric safety test organisation. Swedish elsäkerhetsverket. They took down the Easee charger. And if this isn't protected as you say with two contractors, is it even legal to distribute and sell it?
looking inside, it has all the necessary components! maybe there should be two contactors, but in fact there are already too many contactors in the circuit, the car has two+1s in the battery and one in the PCU, the internal charger has 2+1s with precharge This self contactor is therefore only for safty to interrupt its operation in case of adaptery failure. On the adapter, it is necessary to turn on the 12V relay circuits on the ato side and communicate all toghter and then send the combined can+ information to the ccs CP line.
Why to make an adapter? Is it so difficult to change the ChADeMo to a CCS. How much work does it require to the car itself? Obviously there are several electrical parts that need modifying, and software! But is it impossible?
Great they have made these, now they just need to make another variant where it is a box with the needed electronics and some generic plugs. Make a faceplate for different cars to be able to replace for example the Chademo / Type 2 connector in the Leaf, with a CCS2. The way they should do it is make the box with the electronics a generic box that can be fitted into anycar (Maybe via a car specific bracket) then the faceplate with the connector. Then you connect the faceplate CCS2 to one connector in the box, and another wiring harness that is also brand / model specific to connect into the existing car harness. This way you can fully integrate it, and they only need to make one model of box and then different models of CCS2 plate to fit each car model and a small wiring loom to put in between the box and the car. Oh yeah and then they need to cut the price in half :)
Surely the contactor will only operate when the charger energises the cable/CCS plug? If so, then the one-pole contactor is not relevant in terms of 'isolation'...?
Like Dala I wouldn't trust this when it hasn't been tested for real. I also don't trust that they advise adding a resistor to make it work. Why didn't they put it in to start with? Sounds like they're just trying to avoid giving a refund. I'd be surprised if the resistor solved all the issues. If it did then I'd expect the company to put the resistor in future units BEFORE they ship them out. But I think it's a case of buyer beware - caveat emptor.
Why would there be a requirement of a contactor at all? I guess both the charger and the car are having them. I think they added it to be able to sense the voltage of the car to tell to the CCS part what to supply. Then it need to disconnect the two until measurement is done.
Hi Dala! I have a Hyundai classic Ioniq from 2019. It came with Chademo plug but all around the world it uses CCS. Do you think it will be possible to change Chademo to CCS "easily"? What should I look at in this conversion?
The one contactor not a problem, because, you have 2 contaktors inside car battery, you have 2 contactors in charger - and the HD wires never powered with on end not connected. The 2 contactor reguirment is that, if you put cable on water, then catastrofe happens, put you allready have many conatctors in line, thats already dooing safety stuff both ends! I thinks even one contactor dosent needed, but some safeti 400V DC + is not bad at all! because one is 0V and other is live 400V DC + and you know witc is higger voltage.
Is this the same product you showed and demonstrated in your latest video? And have you been able to use it with multiple different chargers? Has the issue been fully resolved? I'd love to buy one off alibaba, but they're forcing me to buy two instead of just the one, so I'd need to put the second one up for sale on ebay or something like that to make my money's worth
I read on another article that some official Nissan group does not trust this adapter and that it has not been tested in North America. You take risks if the adapter and charger does not work together. Given NACS are the new standard in North America, I might as well wait until the new cars come out with the NACS plug. Hopefully Nissan will go with the flow and place NACS plugs in their EVs. I would love to get another Nissan EV, yet if they sell EVs with no NACS plug, i will have to look at other EV options.
Apparently the chademo company do not approve of these third party adapters. It seems when evs are charging there is communication between the car and charger. It's not as straightforward as using travel adaptors for something like a hairdryer. According to chademo the communication between evs and chargers is also different for the various models. These aftermarket chargers may well appear to work but more needs to be done to ensure they are safe to use. It seems that some of them may not necessarily be weatherproof.
I think it's actually quite awesome what was made here, certainly not easy... but is it legal to use this device? In case of some 'glitch' one could theoretically fry the charger or worse, the battery.... I wonder if both the protocols are secured on both ends to cover such unforeseen usage.
It seems like a better idea to have your CHAdeMo connection in your car converted to CCS. There are companies that do this. In Europe, CCS has become the standard. I don't think the adaptor with a heavy cable is a good idea.
The use of the battery and the need to charge it via USB-C is an interesting choice. I wonder why they don't just trickle charge it off the 12v coming from the pilot pin? Maybe it caused the voltage to sag too much, dropping down too low so that it wasn't in compliance with J1772 voltages? The spec requires "vehicle present" to be ~ 9v via pull-down resistors between Pilot and Signal Ground.
Probably only a very low current sensing circuit not feasible to charge a battery. I had always assumed that a (for long time theoretical) CCS to CHAdeMO adapter would require onboard power, for the communications translation electronics as well as the lock solenoid that is part of the CHAdeMO connector and required for handshake.
this is really interesting! We need affordable ways to get CCS charging for CHAdeMO-vehicles. CHAdeMO-vehicles will be around for several years. Unless they can charge from CCS, they eventually have to rely on AC only, and become short range commuters, without option for occasional long trips. I guess an adapter will probably be the less expensive option. While a CHAdeMo to CCS modification-kit will be more expensive. But a kit will be more user friendly.

Hi Dala,I changed the entire battery pack except the bms. The top part of the casing came damaged and also damaged the bms case so I use my bus instead. Will this caused this issue? Thank you.
That thing feels a bit like those dodgy adapters that gas car drivers use, with sometimes predictable results... 💥🙈 Interesting device however, but I rather see a retrofitted CCS port on the Leaf. That would take away any hassle with supplying 12 V or having double contactors, and CCS is everywhere. Chademo is totally unnecessary, unless doing V2G.

@@trevorberridge6079 I'm not sure if that's true.. Where it is there tends to be only one or two chademo, shared with CCS without dual charging.
I'd like to see the whole thing potted though once the design is more final... at 300V+ DC there is a substantial arcing potential to have that many parts that close together... especially since the contactor isn't breaking both positive and negative.
