Question about the wiring of the CHAdeMO adapter

[johnr]

Could someone who has a CHAdeMO adapter help me out? I'm designing an adapter for the European superchargers for drivers of US vehicles, and of course I need to make sure I get the connections just right. I know the superchargers use the four power pins of their modified mennekes connector for DC, but I'm not entirely sure which ones are which. I believe this should be easy to figure out by testing a CHAdeMO adapter using a multimeter or continuity tester. Could someone test the continuity from the two large pins on the CHAdeMO end to check which ones they're connected to on the Tesla end? Thanks!

Could you maybe add some pictures and circle which connections you mean?

I can see tonight if I can make some sense of it. I have a CHAdeMO adapter. If I don't forget this thread I'll get back to you tonight.

I believe he wants to know which CHAdeMO pin connects to which of the Mennekes pins.

I can imagine it's something like

CHAdeMO DC+ connects to Mennekes L1, L2
CHAdeMO DC- connects to Mennekes, L3, N

Alright, turned out it was correct. As you can see, I am a true artist.

Thanks, Tozz! That confirms Tesla does appear to be following the little-known specification for Type 2 that allows for DC quick charging through a standard mennekes connector, the only difference being that Tesla can push more amps through their beefed-up plug.

I think this US-EU adapter has been made before, by -what was his name ? Weiwei ? The guy who came with mis Model3 to Europe early 2018.
Did not work, probably due to vin-verification.
Keep us posted...

it can be done, so it seems:

For reference, here's a chart I found showing the three compatible modes of the type 2 connection, and the ccs combo variant - I've circled the one that Tesla appears to be using at the Superchargers (the only difference being that Tesla's connector is designed to handle higher current):

No success yet. I believe I made all the right connections, but there's no communication between car and charger. I wonder whether anyone else has had success with this. I've seen that short video clip, but it's strange there's no further info from the person who supposedly made it.
