CCS2 to CHAdeMO adapter

September1

It seems that some Chineese company has managed to created adapter that could make older cars like Nissan LEAF be attractive for longer in Europe, where many new chargers are CCS2 only. Here is video with testing:

and link to device:

I see it requires keeping it charged as it has some computer on board, so for occasional users this could be a problem. I also wonder if they have any European safety certification as this device can handle up to 75kW.

Veru interesting piece of kit. Limited appeal at €1,000 but prices might fall if it starts to sell.

I have been following the developments there and it seems like a proper product. The guy in question, Dala, is a well known person in Nissan forums and as he works for Kempower now his endorsement for the product is great news. He posted some skeptical videos about the product last year but the latest units seem to work well. This really seems like the proper get out of jail card for CHAdeMO car owners that need to travel longer distances.

I would not go rushing to buy the adaptor now as the price will probably fall from the current in next few months as the production kicks off properly and all of the firmware issues have been fixed. Also somebody will need to test it on SuperChargers to see if it works with them too.

Another somewhat related news is that the cottage industry in China has been gearing up for very promising looking battery upgrades for leaf. These seem a far cry from earlier cell by cell conversions. From the 1st vendor below, for example, you can get 40 kWh, 50 kWh, and 62 kWh plug and play battery modules that are securely installed inside the Nissan battery case using custom brackets. The 50 kWh conversion weighs almost exactly the same as the Nissan's 24 kWh battery, the 40 kWh saving some weight in comparison.

Now we'll just need some European resellers and approvals seen as Nissan themselves are not willing to support the older cars.

I could see companies renting out these adapters or one shared between a few friends. I can imagine specialist dealers having them for delivering old leafs to customers.

Price should come down. There is fairly high tooling costs for plastic molding and heavy duty electrics inside and all the research that went into getting it to work. Note compatibility may not be 100. We already see issues where some cars have problems using some chargers so I expect this adapter is unlikely to work everywhere due to different software on different chargers and cars.

Good analysis. One of the smart design features of this adapter is that it's firmware upgradeable over the USB-C port, so should there be any issues with certain equipment that can be fixed.

In an ideal world Nissan would license this product and sell them to Leaf owners, I'm not going to hold my breath for that to happen.

Apparently Range Therapy ( might be going to offer a service converting cars from Chademo to CCS2 At the moment there is a company in the Netherlands who will do it for you.

It would be foolish to pay €3,500 to convert from CHAdeMO to CCS2 if this adapter works and is reliable. With the adapter, you can use either CCS or CHAdeMO rapid chargers for a fraction of the price.

martinosullivan

Yes if the adapter is reliable, it would give you more options. However the other two companies do have more of a reputation.

ELM327

The adapter would also add functionality. Especially for those of us with really old leafs (2011 in my case) that often don't work with the newest chargers due to software incompatibility. (watch Bjorn 500km run in a 2013 leaf, he had the same issue).

That means you could charge at chademo, or use the CCS adaptor. I like it, and if it were readily available in Ireland or with a reliable customer support I'd go for it. It is a luxury and not a need, for sure, as we have 2 longer range Evs for longer trips but I like the idea!

Red Silurian

If this works, and it's looking like it will, it's quite the game changer for Nissan Leaf owners and the resale value of their cars. Also could be very very useful for anybody who wants to import a Japanese car

I think this was coming down the line as chademo and the GB/T organisations are co-developing a standard that could be backwards compatible with both standards as well as CCS1/2 and NACS

ELM327

I'd love to try the adapter and see if the daisy chain could work, CCS2 to chademo, and then use the tesla chademo adapter!

https://www.boards.ie/discussion/comment/121660042#Comment_121660042

You know what to do. And I'll give you 250 quid for the spare CCS converter you have to order. Where do I sign?

Red Silurian

https://www.boards.ie/discussion/comment/121660042#Comment_121660042

There is no reason it wouldn't work, only things I can think of is the CCS to Tesla adapter would be cheaper, plug and charge would be unlikely to work and you'd be limited to chademo speeds

Being limited to chademo speeds isn't an issue for leaf etc drivers as much as availability of charger is

zg3409

Adapter in use in Northern Ireland using the adapter to charge a leaf using CCS only charger. I presume more testing will happen at other sites like Ionity etc.

ELM327

If the adapter was cheaper I'd buy it. Tesla adapters are 200-500 quid, for CCS or chademo. Even 750 would be acceptable IMO. I'd love to charge my leaf24 from 2011 at Ionity !

at 30kW!

ELM327

https://www.boards.ie/discussion/comment/121828085#Comment_121828085

She actually charges pretty well at 48kW, but drops off very badly above 50-60% SOC. I've seen below 10kW before 80%!

Like I say, if these ever become available beyond a seemingly beta release from some dodgy looking seller on Ali, I'll buy one and test it.

If Tesla can sell an adapter (and a ranger to upgrade behind the scenes) for less than €300 I'd imagine it's only a matter of time before this one falls similarly

review on adapter from NI

found to work successfully with rapid chargers from ESB, Ionity, Maxol and Weev.

The adaptor currently fails on EasyGo and BP Pulse units, although the BP chargers are known to be finicky and won’t, for example, charge the Telsa Model S or MG4 currently either.

ELM327

https://www.boards.ie/discussion/comment/121847316#Comment_121847316

Does it work for 2011 leafs? These are known to be finicky too

https://www.boards.ie/discussion/comment/121848367#Comment_121848367

The early leaf support worked very early so the adapter can talk to all of the cars without problems and as a matter of course this kind of product is great when the car has known problems with newer chargers as the adapter masks those. So potentially the old leafs will be able to charge on more CCS chargers than the early buggy CCS cars.

Currently the firmware updates are dealing with the charger to the adapter side communication problems. The SuCs don't work at the moment at all and that's bit of a bummer if it's something that can't easily be fixed.

Did we get one to @ELM327 for his CCS ⇒ CHAdeMO ⇒ Tesla test yet?

Maybe we need a gofundme

ELM327

All joking aside (I have the chademo adapter but no Tesla that can take it, the 3 is CCS only) it would be useful to have this for my leaf. Too expensive for a novelty item IMO but if/when either more people have it (so I know it is reliable) and/or it comes down in price I'll be getting one for the leaf. Not that many chademo stations around but even those that do, tend to have one chademo plug for multiple CCS plugs. And a l24 is a car that needs charging!

I'd like a situation where a group get together to share one. We are on long leaf journeys about 4 times a year between July and August. Zero point investing €1k for that usage especially without a warranty of any kind.

Now if we had 5 close neighbours or family willing to chip in and take the adaptor for 2 months each and we all pay 1/6th the price each (~€200) now you might be talking

Or, as a business idea. Buy them and rent them out. Would somebody be willing to pay €2, €5, €10 etc a day to rent the adaptor?

ELM327

On the sharing front then you get into timeshare issues where everyone wants it in July and no one in December etc.

I don't think it would ever pay for itself with renting it out either. At current prices it's a novelty or convenience item, rather than something that makes economic sense.

slave1

Surely an old 24 leaf wouldn't be able to take a massive rapid charge in any case, probably in the 20s kW, as ELM said, an overpriced novelty, there are still plenty of CHAdeMOs

10 to 80% in mine is like 10-12kWh, If I could get it fitted with 11/22kW AC it would be a better spend

Red Silurian

https://www.boards.ie/discussion/comment/122168327#Comment_122168327

Range Therapy advertised 3 phase charging at one point but not sure if it ever materialised.

Thinking outside the box for a minute. If you could get a 22kW AC/DC adapter. IE you rock up to an ecars pedestal, plug one end into the type 2 AC pedestal and the other into your Chademo port to charge at 22kW. Presume you'd need a box somewhere along the cable but potentially a cheaper option than a ccs/chademo adapter, and it would open many more fast charging locations

ELM327

https://www.boards.ie/discussion/comment/122168551#Comment_122168551

I wouldnt give those fools at range therapy the light of day but that's another story.

There is an adapter than does exactly what you want. It costs over 5k from Setec. (I investigated it years ago!!)

Red Silurian

https://www.boards.ie/discussion/comment/122168593#Comment_122168593

Range therapy seem to be more concerned with their range trailer lately anyway

5k? Ouch! Definitely not worth it

zg3409

https://www.boards.ie/discussion/comment/122168551#Comment_122168551

I believe range therapy guy has just that box. 22kW AC to DC, large box, it was for sale again at one point. I think they said it would not work on ESB ecars public chargers for some reason but would work on standard 3 phase factory supplies. Again a bit slow not really ideal for fast charge, too fast for overnight charge.

Red Silurian

https://www.boards.ie/discussion/comment/122173632#Comment_122173632

Curious that it wouldn't work on an ecars unit. Not much use for speed but for availability it's great as every AC point in the country would become (an admitedly slow) Chademo charger

Their customer support is on Telegram!

As always with sites like that, buy with card/PayPal/other buyer protection.

Red Silurian

https://www.boards.ie/discussion/comment/122253623#Comment_122253623

Sorry for the ignorance but I'm not familiar with telegram… Is that a good or a bad place for their customer support?

ELM327

https://www.boards.ie/discussion/comment/122253632#Comment_122253632

Telegram is like the who's who for dodgy people. Often used by far right or far left political loons that are banned from everywhere else. Think like Truth Social (Donald Trump's twitter alternative).

Red Silurian

Ok so my main concern at first was that the adapter would damage my car, buying with Paypal isn't much good in that instance.

Now with this included I'm sorely tempted to steer clear

ELM327

I doubt it would damage your car. The risk here is that it doesn't work as intended. I'm happy to see the prices becoming cheaper. If there was that price from a more reputable looking seller I'd buy it. I paid similar for my CCS adapter for the model S.

zg3409

https://www.boards.ie/discussion/comment/122251374#Comment_122251374

No mention on website which country it ships from. If you assume Hong Kong then duty and vat will apply. Website is rough and missing faq.

If it has similar software to the one tested in Northern Ireland then, as per this thread, it's likely it won't work on lots of Irish chargers and that issue may only be possible to fix on the charger side of things and not by updating software on the adapter.

At least the other crowd selling it had some Irish and European public tests. I would hold off for as long as you can.

Maybe I'm overly cautious but I'm always careful with electronic devices from questionable sources, moreso when that electronic device takes massive current and voltage and is plugged in to my car. The CE mark in one of the photos does get me thinking I'm being overly cautious

zg3409

From Facebook (not me) (note ESB ecars have lots of different brand chargers so may not work on all)

I started testing one yesterday down here in Cork.

So far it's worked on two out of three CCS2 chargers.

ESB (Delta) - yes

EasyGo (ABB) - yes

EasyGo (Tritium) - no

I haven't yet gone through the debug process of logging the handshake data between car and charger and sending it back to the manufacturer so they can create a firmware update for me to try. Conrad tells me the Tritium chargers can be tricky and take a few iterations.

Red Silurian

https://www.boards.ie/discussion/comment/122895117#Comment_122895117

I'd be very interested to hear if they work on Tesla SCs or Circle K chargers, purely from a reliability point of view.

Overall it seems like a decent well built product to be fair. We have a Leaf in the house and will probably hold on to it for a while so mulling this over. €1k+ is a lot to spend if it doesn't work though

zg3409

In terms of UK seller of adapter for 600 euro a guy called Conrad Wu from one of the UK Leaf groups.(Sells on eBay) He drives a Leaf himself, and he's filed a lot of incompatibility reports with the manufacturers and got firmware updates back from them to resolve. Some chargers, Tritium/Veefil in particular on different networks, seem to take a few attempts. For example his UK firmware (that works on UK Tritium chargers) doesn't work on Easygo Tritium chargers here. I'm on the third firmware iteration of testing atm. (From another group)

In fairness, some people have trouble with chargers and it's their own stupidity, not the equipment. Only last week, I was waiting to topup the Model 3 at the Blanchardstown SC fast charger. All spaces full. A woman in a Model 3 was had the CCS charger cable in hand and I don't know what she was doing, but she didn't plug in. I thought she was ending the charge, because by his stage, I had been stopped and waiting a good 5 minutes. Then she was plugging her type 2 cable into the car and tried connecting to the charger. She got into her car with the cable and drove off, shouting to me that the charger is offline.

I parked, tapped and plugged in. No problem. Charge started right away. No doubt she was complaining about broken chargers, but sometimes, its human error and nothing else.

I'd have offered help, but I was not parked up in a parking spot and an ID4 taxi was waiting to take the next free charger, so my finger was on the trigger. I also wasn't sure what was happening until she was leaving and shouted about the broken equipment.
