I got the cable Mennekes to Tesla 
Hello together,
I have a prototype now and I'm planning to Certify it and produce this adapter in China.
I'll post when it will be available. See also the news here: Hotels mit 32A Stromtankstellen

ni torn,
great news! count me in as well. out of curiosity how are you getting the tesla ends? are you having them reversed engineered in china?

This type of cable has taken on a renewed urgency now that we've had announcements of more than 4000 charging posts with Mennekes coming to the UK.
Also, I noticed in the Walther range there is a 63A plug now. Part # 726 00 00 00.

I'm curious how you can possibly solve the 3-phase to single-phase problem when making a Mennekes to Tesla connector? Or M to J1772? I'd like to help you find a solution but correct me if I'm wrong - I don't think your biggest problem is getting a supply of Tesla connectors. Even if you had a cheap source for those, how would you use the 3-ph power coming out of the Mennekes plug? It would be relatively easy to modify the PEM to accept 3-ph but Tesla pretty much has to do it. By contrast it would be quite difficult to convert 3-ph to single. Am I missing something?
No you've pretty much summarised it.
If we could get one phase from the plug it would be better than nothing. To use all three phases in balance would require a rectifier-inverter (or a rotary converter but let's not go there).

Why not go there? I'm generating the power to charge my Roadster by spinning a 3-phase motor. By experimenting with multiple capacitors I was able to convert it to single phase. It's only about 85% efficient but relatively cheap. OK, I confess it's not very portable!
To use only one phase from the plug, how many amps would that be? It sounds to me like it's a simple case of wiring a Mennekes plug to a Tesla connector. No? You don't even need to generate the pilot signal - you can just pass it through directly from the M connector. Have you already tried this? Is that what EV Box did?
Yeah I was thinking about the portability angle. How easily would a 16kW unit fit in the trunk?
If you were able to take 32A from one of these posts then it would be 7kW. Not great but not bad either. The spec allows for 70A on one phase but no one has implemented it yet that I am aware of.
We haven't tried it as getting the Tesla connector is a pain, but I think that is what EV Box have done (by butchering a cheap cable).

It's hard to know how big a rotary system of that capacity would be. The converter is theoretically not consuming much power.
Yes a pain - pay $600 for a spare mobile adapter; drill and tap the end piece for a larger strain relief; drill out the spacers in the crimp sleeves to accommodate heavier gauge wire. Do you have a reasonable source for the M plug? Yes a pain but at least then you can travel.
How many could you sell if these were priced at about $750 (using only one phase)?
Clipper Creek has a unit out UL certified to 70A

Widodh (up thread) has a source of Mennekes plugs. There was a supplier in the US too I seem to remember. Anyway they are getting more common.
We had a discussion about a group buy. I think $750 would be acceptable.

You didn't really answer my question. Would 100 people buy them at 600 EUR? or 10? They would be 70A capable.
I saw the group buy thread but it basically ended without a group buy. There was a lot of complaining (legitimate) about their price and functionality. And of course up-thread somebody claims they are having one made in China but he seems to have disappeared.
Yes, I certainly want to buy one, too. On the other hand, I'd actually rather prefer to change the proprietary socket in the car to a Mennekes socket. This way I could get rid of any proprietary cabling at all. Has anybody thought about this yet?
I guess aside from potential technical issues voiding the guarantee is probably the biggest issue.
