In view of the issue I have with my onboard J1772 socket, I'm looking at ways to maximize use of a portable chademo. There must be a way to adapt mennekes and Tesla outlets to 3 phase sockets. As far as I'm aware, there are no commercial adaptors in existence so it will be a matter of creating them. I recall seeing a photo someplace of a Leaf recharging at some MacDonalds via a Setec portable chademo but I can't recall what the chademo was connected to. Presumably there will be some jiggery-pokery with Tesla which may mean that adaptor has to be left to the likes of Gelco to create, but isn't mennekes more straightforward ? |

Yes, this has been done before and there are a few on this forum with portable Chademos and Tesla/Mennekes to 3Ph 32A socket adaptors.
Is a Mennekes adaptor like this straight forward to make, well yes, as it follows the standard signalling.
No doubt Gelco could make the adaptor you're after as presumably he's already sorted the signalling for Tesla stations. He just needs to wire the Mennekes plug to a 5 wire 6mm2 cable and 3ph 32A socket rather than the 3 wire 15A/32A sockets that he offers now for $360/$425.

I've been on the phone to Bob this morning regarding the various adaptors. Seems he's never been asked for 3 phase / Setec adaptors previously but I've sent a list of what I'd like and now its up to him to see what he can do. As you say, a Tesla to three phase adaptor should be fine but a normal mennekes to three phase might be a different event. Not a biggie right now as there are only the two Griffith University locations (Parkwood and Nathan) and I believe Toombul shops with mennekes at present, and they all have three phase Tesla. I'd like to have both single phase and three phase Setec capability but I need to understand a lot more about that then I do at present. There are a few places where I could make use of single phase input, like J1772 and single phase Tesla sites of which there are a lot more in my area than regular three phase outlets.

 There are a few of these around that have mennekes outlets with a tethered adaptor j1772 cable. I charge my leaf at this one at kawana shopping centre on the Sunshine Coast. Not sure if they are three phase, but I assume they would be. |

Not sure if they are three phase, but I assume they would be. Given that the Tesla chargers on both sides appear to be three phase, its hard to imagine the mennekes outlets aren't also three phase.
I'm having difficulty understanding how a mennekes connection with seven pins can have three active phases, a neutral, and earth plus proximity, control and protective earth (8 in total)
According to Wikipedia
The connectors contain seven contact places: two small and five larger. The top row consists of two small contacts for signalling, the middle row contains three pins, the centre pin is used for Earthing, while the outer two pins used for the power supply, optionally in conjunction with the two pins on the bottom row which are also for power supply. Three pins are always used for the same purposes:
Proximity pilot (PP): pre-insertion signalling
Control pilot (CP): post-insertion signalling
Protective earth (PE): full-current protective earthing system—6-millimetre (0.24 in) diameter[1]
The allocation of the four normal power supply pins vary depending on the mode of operation. They are allocated as one of:
Neutral (N) and line (L1): single-phase AC
Neutral (N) and line phases (L1, L2, and L3): three-phase AC
Neutral (N) and line (L1); negative (−), and positive (+): combined single-phase AC and low-current DC
Negative (−) and positive (+): low-current DC
Negative (−, −) and positive (+, +): mid-current DC
Communication takes place over the signalling pins between the charger, cable, and vehicle to ensure that the lowest common denominator of voltage and current is selected.
From what I can understand of the Wikipedia explanation, the three phases share a single pin ...... didn't think that was possible but live and learn.

This link shows a picture of the Mennekes or Type 2 plug www.google.com.au/search?q=wiki+mennekes+type+2&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwi9oqTRpuTbAhVCk5QKHYuKAWsQsAQIqwE#imgrc=Cp-ZgTrtStriKM:Three active phases, a neutral, and earth plus proximity, and control adds up to 7 pins total, not 8. "Protective earth" is the same as "earth". The single phase version is the same except L2, and L3 may not be there. So 5 pins, and the pins are one-for-one with the equivalent pins on a J1772 or Type-1 plug. I would not worry about the DC versions as only Superchargers use them in Australia. |

Yes, like any 5 pin three phase in Australia all three phases share the same neutral (and ground) wire. Even if you are running 32A down all three phases simultaneously because they are out of phase they never have more than 32A in total on the neutral line. |
