For years, the CHAdeMO Association has maintained a list of fast-charging units compatible with CHAdeMO and vehicles which can use the standard.

To date, all the EVs recognized as compatible on that list had CHAdeMO charging inlet, but now the list includes the Tesla Model S, which can use CHAdeMO via a separate adapter.

We already know that on some markets, where the CHAdeMO network is too big to fail to big to build up a competing system (like in Japan) manufacturers will be using CHAdeMO.  Tesla prepared this adapter for such regions.

For the CHAdeMO Association, it’s another way to show that the standard is alive and growing in all aspects – number of points, number of modes etc.

Who knows, maybe next the BMW i3 will get added to the CHAdeMO-compatible EV list?

Great news… So far Chademo’s only compliant car that sells in any volume has been the Leaf. I’m hoping Mitsubishi, Kia, and Tesla will be changing that.

That adapter looks huge, though. I’m curious to see a demonstration. Hard to believe the charge port on the Tesla can support that thing. I have used Chademo on my Leaf and that connector and cable are big and heavy.

Will it fit in the frunk?

i-Miev sold 30000 times and counting.

Wow! A Nissan leaf with 228km driving range.

Oh, wait – JC08 mode?
That must include a segment where we all get out and push.

Yeah, people like the bash the EPA but at least their MPG numbers and range ratings are close to real world numbers unlike so many other testing regimes that seem to be based in lands of all downhill & tail winds.

Chademo rules Japan. If you want to sell there, you need to do Chademo. Both Tesla and BMW have accepted that.

Have we seen how BMW will incorporate a Chademo port into the i3? It’s definitely not going to fit alongside an AC charging port under the existing flap…

AC port is in the frunk.

I assume you meant DC port in frunk?

Has Japan slowed down on EVs due to Fukushima? With the Nissan Leaf and i-MiEV, they seemed to start off early . . . but they’ve pretty much released nothing new (except small volume demos) since then.

Outlander PHEV was a big new release in Japan. There may be some other kei cars that I don’t pay attention too also…

Weird, the Infiniti sedan is on the list despite being canceled before even getting out of the concept car phase.

CHAdeWoah… That’s a HUGE adapter!

Not to mention it costs a grand. However, it’s still just vapor as it hasn’t shipped yet.

Lets put it this way… Tesla owners in Japan stand a much better chance of obtaining one, than anyone being able to buy the Mazda Demo EV, also listed on the same page. 😉

It’s only 400$ if ordered with the car, or the supercharger option on the 60 kW*h version…

where do you see that? The Tesla web site makes no mention of it.

Hmm, I can’t find the pricing for the S 85 anymore either, but here it is for the 60:

Supercharger option: 2000$
Supercharger + CHAdeMO adapter: 2400$

Yeah, I see that now. Interesting that Tesla charges 400 when bundled with supercharging but 1000 for those who bought SC with the car. Hmmm, something else to complain about…

by the way, that page doesn’t say it turns on supercharging, just activates the hardware. Not clear if that means you get supercharging.

That’s one dollars of plastic and metal and 399 dollars in the pocket. Easy money…

Do you really believe that? If I were to guess, the adapter converts between the CHAdeMO charging protocol and the Tesla charging protocol, so it’s kinda like a mini EVSE in and of itself.

It doesn’t look like. So to see, it is just wires cut on one end and a larger plug fixed on it.

After you’ve built your own working version, throughly tested it, got it certified, and can undercut the retail price overseas– I’ll believe you.

You sir have no clue what you’re talking about.

CHAdeMO uses CAN for communication, plus a couple misc failsafe/interlock signals.

The Model S has its own variant of PLC. Not at all the same protocol, not even the same media, so a non-trivial, active adapter is required between the two.

Great, so we can’t use the superchargers, and Teslas can suck up our CHAdeMO time? As usual, we’ll see how that plays out first on the west coast. It would be nice if CHAdeMO could put out the full 100 kW the standard allows.

So, you think it’s unfair that Tesla has put more engineering effort into support charging their cars than other EV makers? Seems like envy to me. Just remember, Tesla owners don’t get use of superchargers for free – they have to pay up front. Bundled cost is $2000, $2500 to add it on after the sale.

Yes, envy. I have to recharge a lot more often. But you’d have to travel a lot to recoup that upfront cost. I’d rather there be one standard that we all can use, and pay by the kWh.

If there were enough 100 kW units at each site, waiting to charge wouldn’t be an issue.

LOL. Yeah.

By the way, using average cost of electricity, $2K as the burdened cost, 330 wh/mi and 85% charging efficiency, that works out to about 45K miles of driving for a Tesla owner to break even. So, I’ve got to majorly hog the SCs to to even come close. Not gonna happen. I like charging at home.

But, I don’t feel my $2K was wasted as it’s helping to build a rational, well thought out national (international!) fast charging network that supports long distance EV travel.

“Great, so we can’t use the superchargers, and Teslas can suck up our CHAdeMO time?”


CHAdeMO is an open standard for charging evs that can be adopted by anyone and was developed by many entities with massive support.

The superchargers were developed by one company because all the open standards were taking too long and/or were too slow.

Or maybe you should not be allowed access to a rental car if you have one of your own.

Tesla could add CHAdeMO and sell access by volume, and it would be in their interest to help grow the overall market.

On the plus side, Tesla drivers will help support the growing CHAdeMO infrastructure. But already, there are reports of EVs waiting to QC, and now they’ll be more of that. If that spurs more QC installs, great.

Part of the problem with your statement is “with massive support”. Charging networks as profit making entities is not going to happen. The math just doesn’t work since charging at home is always going to be significantly cheaper. Apartment dwellers might be the exception but to date that really hasn’t been much of the EV buying public. Free EVSEs will go away – they are early incentives and those funds (mostly governmental) will dry up. Free QCs will go away even faster. So we are left with only companies that see CQ EVSEs as a side part of their business plans (like Tesla). To date, no one else has done so.

And, for what it’s worth, Tesla will never, ever add chademo to their SCs. The adapter came about because of the Japanese market and US owners (like me) screamed bloody murder when they said “won’t sell it the US”. They held their collective noses and supported it.

Is this company publicly traded yet??

Which company? Tesla?


The CHAdeMO Group is run as an association, not a company:


It would be neat if Toyota took that eQ and made it the fastest car ever built. Just to show everyone up.

To bad that the bulk of CHAdeMO chargers in the US are at Nissan dealerships.

NRG eVgo is building dual standard QC out all over California.

I doubt you’ll see many Model S drivers using CHAdeMO unless they really need to, and then likely only enough to get to their overnight charge stop or SuperCharger.

Maybe NRG should focus on making the existing charging points around Dallas functional first.

“I doubt you’ll see many Model S drivers using CHAdeMO unless they really need to”

I doubt you’ll see [any EV] drivers using [any charging more expensive than at home] unless they really need to…


While there are some exceptions, that is very much how it is turning out.

Three exceptions:
– free charging. this is going away in general as the need for EV incentives declines.
– apartment dwellers. currently, the number of EV owners in apartments rounds to zero. There are exceptions but they either have charging at work or are gluttons for punishment…
– long distance travel. ala superchargers. this is where I see chademos being of use.

The problem for long distance travel is that all the current CHAdeMO installations would have to be replaced. At 50 kW nominal, they just aren’t fast enough to support a reasonable cadence for long distance travel. Even Tesla’s 120 kW is barely fast enough.

The other problem is that current CHAdeMO install costs are almost an order of magnitude higher than 80A J1772. Which means it is nearly impossible for them to be reasonably profitable and certainly cost prohibitive to install many of them. Each charge point for CHAdeMO is $20,000-60,000. 80A J1772 would be somewhere around $4,000-7,000. At 20 kW and using 208/204v single phase power, 80A J1772 would be far easier to install and provide a cost effective means to charge most EVs. 50 kW EV charging doesn’t make any sense at all.
