    Conversion Tesla Adapter to Mennekes socket

    I visit my nearest public charging station with 32A current at the ADAC Fahrsicherheitszentrum in Nohra Thuringia close to Erfurt/Weimar.
    Only to find out, that this was a new 7-pole Mennekes plus Schuko-socket with 16A.

    I was disappointed not being able to charge at all, because i had only my UMC with me.
    32A cut the time to charge in half dispite the fact, that i could not charge there with 3-phase too. I send a message to my Tesla customer officer to ask for an adapter for those Mennekes socket. He was very sorry for not being able to support me with this kind of socket, because not being an approved standard.
    I also talked to some employee from RWE eMobility. He confirmed, that they have some handmade adapters for their Tesla Roadster.

    With growing numbers of RWE charging stations in Germany it makes more and more sense to get a working adapters.

    Who is able to make conversion or has more information about the used protocol?

    It is an approved standard by VDE.

    Wiring the connector shouldn't be the hardest problem, but it's the communication with the charging station isn't it?

    But Tesla seems to support the DC charging and the J1772 standard, so it's a bit of a lame excuse to say "It's not a standard"

    I got a call today from Tesla NL and they told me that a Mennekes adapter is available here in the Netherlands.

    The Roadster of my colleague will be there in 2 weeks. I'll make a picture of it and upload. If the connector works, you might be able to order one at them or I could ship it for you.

    Pictures of the connector tear down here: http://wegmuller.org/v-web/gallery/MC120TearDown (the gallery has two pages).
    his homepage looks as if he could build a Tesla connector from scratch

    Mennekes is developing an adaptor, but I'm not sure if I want to use the RWE charging stations, you have to have a contract with RWE, pay a monthly bill about 19 EUR and no roaming yet. Their charging stations are at places, where I wouldn't need them, towns, parking garages, ADAC. ADAC, what should I do there with my Roadster ?
    Do they at least offer a coffee ?
    Better places (for me) would be motorway stations at the autobahn.
    Last year I asked a motorway station group about charging, answer was : ask next year.

    Best solution of course would be the 3 phase mobile charger. From now on I will include that in my morning prayers.
    There are so many nice private charging stations in lemnet.org. I took some pictures and will promote them as soon as I have more time in a different thread.

    Yes, i got a free cup of coffee. The charging-station is from E.ON Thuringia not RWE. Another player in the market is vattenfall.
    I was the first who wanted a charge after being opened three month ago.

    I want to install another 32A CEE in my underground garage, would prefer to do it with the new Mennekes.

    JB Straubel promised me 3-phase charging for Model S, hope the will have Mennekes.

    Up to 16A there is no communication needed. The roadster will default to 16A if there is no control pilot signal present.
    If you want to charge at a higher Amperage, then you just connect the pilot pin of the Tesla connector to the CP pin of the Mennekes connector.

    There is no conversion needed for the control pilot signal, The signal is the same in Europe.

    I'm planning on making a 16A Mennekes -> Tesla charge cable. I have the cables, now find some time to buildt it.

    Martin Eberhard's thorough documentation of his "Roadster Foundry" mobile EVSE may be helpful for building a Mennekes adaptor. Here is a link:

    I was thinking about a plug for the Mennekes with the signal for 32A and a short cord to a red CEE 400V/32A socket for my UMC cabel with CEE 400V/32A plug.

    Isn't the communications protocol identical ? A simple Mennekes-Tesla cable with NO electronics at all should suffice ? Just like the simple J1772 adapter someone made ?

    I guess the problem is getting a 70A rated Tesla connector. A Mennekes-cable/connector should be easy enough to aquire.
