Hi TEG,
Hope you're well.
Not sure if you realize that I have 2 Teslas. I am certain that you're aware they have two very different batteries TEG.
Two vehicles with 2 separate questions in 2 different forums.
I bought the CHAdeMO ADAPTER for the Model X, but that has NOTHING to do with the CHAdeMO CHARGER I purchased from California for my Roadster.
I agree fully with gregd. I am using the JdeMo for 2,5 years and it works great.
This set is keeping me on the road as Tesla does not. My CAC went down to 110 at 350.000km, purchased the JdeMo and now my CAC is 93 at 414.000 km. I can not tell if degradation is stronger with this set since the battery is so old (>1250 cycles) that nobody ever anticipated it would be possible to keep on driving like this and it is said degradation speeds up anyway after end of life of 1000 cycles.
I ordered a new pack 2,5 years ago. Never get any response from Tesla anymore so they have little to say I was "forced" to put in this set to keep my roadster on the road.
Most likely if ever a new pack with an acceptable range will be available I only need the JdeMo for long road trips (>500km).
By the way, due to higher internal resistance in this very old pack the JdeMo charging already start throttling down at 80 km (45%) range. So in general I have to charge 40 minutes to get the pack from 30 to 150km range.
I have a JdeMO installed. I have only used it twice, so I cannot speak to degredation. I have it as an option so that if I ever want to take a longer drive, I have some sort of faster regen available. I won't be using it routinely. Having said that, the team that installed it a Electrified Garage told me that the firmware update for the JdeMO from QC Power that will allow even faster charging actually pushes current at a higher rate than the install (and some part of the Roadster's hardware, if I understood correctly) is rated for. So the Electrified Garage team recommended that I not have the firmware updated. QC Power doesn't believe it is a problem.
OK, so now I know what these are for and their purposes for fast charging for our Roadsters... but what charging stations are these compatible with? My Roadster is more or less a toy, so I don't see myself going far from home with it, but would still like to be knowledgeable about it.To answer your question (ok, to guess at an answer to your question), I don't think the JDEmo adapter will cause damage to the battery. From what I've read, the way it works is to trick the car into thinking it's in Regen mode, taking energy from the CHAdeMO input and feeding it into the battery as if it came from the motor. Quite clever, actually. The motor is capable of about 40kw of Regen charging (so the battery and such are designed to handle that level of current), and the car has a good active cooling system for the battery. There's a management processor in the JDEmo box that regulates the charging process, keeping it within safe limits. As with any EV, frequent high-current charging probably isn't the best for the battery, but if you're just using it for occasional charging during a trip, I wouldn't be at all concerned about battery health.
Oh, and "might damage your car" is a standard answer when any manufacturer is faced with 3rd party equipment. They even blamed my OVMSv3 for causing some fan-related alerts. Sheesh...
In theory, any "CHAdeMO" high speed charging station. In practice, I don't know what brands or such. Others can chime in...OK, so now I know what these are for and their purposes for fast charging for our Roadsters... but what charging stations are these compatible with?

Thanks.

EA is usually limited to a single CHAdeMO at a location. They're not motivated to push a standard that their owners at VW/etc does not support. They have the one to comply with terms of their settlement.EVgo & Electrify America stations usually have both CCS & CHAdeMO
Not sure they are back in stock.... I was told I got the last one. Sorry
Tony Williams [QC Power] posted on the Roadster Owners’s FB group that the last Jademo unit was shipped and they are no longer making the Jademo for Roadster due to lack of demand.
There were only approximately 50 total units shipped : most going to Europe, several in Japan, a few in Australia, and only about a dozen in the US.
Interestingly, the assembly was designed to handle CCS-Combo protocol.
I have Jademo installed on my 1.5, but like others, have only used it two or three times. It worked well, I just haven’t taken enough long trips.

I just spoke to the staff there at QC, and the CHAdeMO is NOT designed to handle CCS-Combo protocol.
They are considering making an add-on that will attach to the CHAdeMO device, but they explained to me that CHAdeMO and CCS use different communication protocols that are not compatible..
