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:

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.

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!

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!

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?

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!

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.

It's showing as €745.38 if you buy 100+ units, got 99 friends?

We should start a list 😁

I'd buy 1

Red Silurian

Same, so that's 97 more interested buyers to go

ELM327

https://www.boards.ie/discussion/comment/121830624#Comment_121830624

I don't have 9, let alone 99!

Nah, I'll just wait till the price comes down I think.

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.

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?
