I suspect Tesla won't be pleased with this sort of development, since they have promised to make superchargers free for ever [ edit: that policy has changed, and superchargers are DC, this is a destination charger ], so they don't have a mechanism for charging (as in money!) customers. Other EVs who haven't paid anything to Telsa may be taking up spots that Telsa owners need.

Maybe if this becomes popular they can work out a way to make it all legitimate.

These Tesla chargers are just glorified EVSE"s with J1772 pilot signal and all...

I suspect if Tesla want to stop non Tesla vehicles from charging they'll simply add some extra proprietary negotiation between charger and vehicle, or alternatively add some proximity detection device using NFC, RFID or even possibly GPS.

Doesn't the RAV4 ev have tesla running gear ?
So in a way it is a tesla anyway

There is also another video from the same person of a BMW i3 charging of a HPWC

Very interesting.

These videos were made in the U.S. where Tesla has a proprietary connector - which Tesla supplies with a simple adapter to charge at j1772 stations, the signalling is the same.

In the rest of the world (everything except USA/Canada/Japan) Tesla uses a "Mennekes" style socket. Once again our Teslas can charge at J1772 stations with a J1772 to Mennekes adapter, although we have to source these seperately because Tesla does not supply them.

A Mennekes to J1772 adapter would most likely allow you to charge your non-Tesla EV on a Tesla HPWC.

That would only work on the HPWC ("high power wall connectors") because at the end of the day they're just a glorified power point with signalling, like any EVSE.

A simple adapter won't work with Tesla Superchargers, because the supercharger talks to the car's BMS via CAN (so the car can reduce the charge current when required) so you would need a device that simulates a Tesla, and provides a fake (but valid) VIN - and of course would need to translate that to something your car can understand (ie CHAdeMO or CCS, depending on the car)

You might as well charge on a CHAdeMO or CCS charging station, which will hopefully continue to outnumber Tesla supercharger locations.

Also, apparently plugging a Renault directly into a Tesla single phase HPWC is a bad idea because of the way Tesla wires the single phase input into all 3 output phases, and there's disagreement if signalling 32A available means 32A total or 32A per phase.

Can I charge my Renault with Tesla UMC

That was using the Tesla mobile charger with 32A single phase socket, but the single phase HPWC is wired the same.

Further to this, the supercharger plug won't fit in a non tesla mennekes socket anyway. The socket on the tesla has an indentation that a normal mennekes (type 2) plug does not. The supercharger plug has a matching notch, which fits in to the indentation on the car socket.

There is also longer pins that increase the contact area for the high current transfer.

If you put aside the issue of Superchargers which I understand can't be used on non Tesla vehicles, would it be possible to source a compatible Tesla Type 2 Mennekes inlet ? What other challenges would be faced to make a J1772 adaptor?

Yes, you can get the bits from aliexpress. I have bought from JPSON and the quality is good (j1772 inlet, lead and plug).

You would need a type 2 (mennekes) inlet, and a J1772 lead and plug. You simply connect the L1 pin to the active of the J1772 lead. L2 and L3 do not get connected on the mennekes inlet (for single phase they are only connected in parallel anyway).

Obviously, pilot, proximity, neutral and earth would be connected as normal.

Don't be tempted to common L1, L2 and L3 at the inlet. While that would work fine for a single phase HPWC, if it were plugged in to a 3 phase mennekes supply, it would cause fireworks.

I suspect we haven't seen it because the plugs and inlets aren't that cheap. Minimum $300 I'd guess.

I'm needing some advice for wiring up an adaptor cable as the thread describes. A Mennekes inlet to J1772 vehicle charger for charging a Outlander PHEV with a Telsa HPWC.

I have wired up the J1772 with CP, L, N and E through to the Mennekes. The PP is wired in the J1772 with the microswitch and resistors to earth (it does not connect to the PP of the Mennekes).

I plugged the adaptor cable in my PHEV and it doesn't quite work. The charge symbol on the dash flashes but doesn't go constant. I don't hear the Tesla HPWC or PHEV relays click so something is failing in the negotiation perhaps (maybe the PP wiring?).

Any advice appreciated.

i have the same issues, from my understanding, there are some resistors that need to be added into the signalling lines, but im unsure of whats exactly needed, i am not sure if its the same added to the ones that work on the Nissan Leaf. but im looking into it.

I know a straight Type 2 to J1772 adaptor works with the single phase Tesla HPWC's with the Outlander, yet to test my Imiev. but will shortly, i know the Outlander and Imiev wont work with the adpator from 3 phase tesla chargers

Tried bob gell’s Adaptor.
Works on rac electric highway circontrol fast ac type 2 3 phase, but not on Tesla hpwc type 2 3 phase.

http://gelcoservices.com.au/gelco_electric_vehicle.htm
His team is working on a cable that works on 3 phase hpwcs. Still waiting. Now his hpwc adaptor listings are clearer. “Single phase” added.

Bob’s new model with switches works on 3 phase Tesla HPWCs. Not ip66 though.

What is the latest state of play regarding Tesla adaptors ? I've noticed a few units which end in a standard 3 pin socket averaging a bit over $AU300.
This seems exxy given that the only bit that would cost anything of consequence is the Tesla piece.
Is the wiring and whatver a closely guarded secret and is there more to it than just connecting a few wires ?
How many different Tesla configurations are used in Australia ?
From what I've read, there are single phase 240v, three phase 415v and supercharger (which is reportedly only usable by a Tesla vehicle)

Originally Tesla supplied single phase HPWC's in Oz. Easily spotted with a metal front and the wand does not stow on the side of the charger. A while later Tesla started supplying 3 phase versions. They both run standard J1772 signalling but there are caveats.

Tesla uses both PWM and LIN comms to the 3 phase variants, to update firmware and possible future features. This can affect some non Tesla vehicles. But Delta Power Systems (who make them for Tesla) have added a mode switch to run in Tesla mode or Legacy mode. I suspect the legacy mode removes LIN communications from the HPWC.

These adaptors with multiple switches added try to overcome the Tesla mode set.

I tend to not like these adaptors much. They "overcome" the safety functions of the J1772 protocol. I would rather people not kill themselves charging EV's....

I just discovered another issue (mentioned in a different thread) affecting privately imported vehicles. Seems there are two pins in the onboard J1772 plug that are not used in Japan, and this means that Type 2 to J1772 and Tesla to J1772 cables won't connect.Reportedly the Tesla to 16 amp 3 pin adaptors will work with a regular EVSE. In view of the expense involved in re-wiring the J1772 plug to take advantage of the two Type 2 charging stations I'm aware of in my area (both of which have Tesla points adjacent), I'm inclined to go with a portable chademo instead.

I ended up doing my adaptor but had to change to 240v outlet to the plug the ev charger into. Pics attached and circuit diagram in case someone is interested.

Does someone have a circuit diagram for the Tesla connector to J1772 with the two switches pictured above?

The 220 ohm resistor tells the charging station that you are using a 32 amp cable. Since your GPO is only rated at 15 amps you may want to change the PP resistor value to 1500 ohms. Just to be on the safe side. Assuming you will be using a level 1 EVSE cable to plug into the 15A GPO.
5.000V (no external resistor detected)
3.000V (1500 Ω resistor - 13A cable)
2.024V (680 Ω resistor - 20A cable)
0.902V (220 Ω resistor - 32A cable)
0.455V (100 Ω resistor - 63A cable)

That is good to clarify - I wasn't sure what its purpose was but now I know. Given that it's to be used with a L1 evse it's not really possible to draw more than 15a anyway. Im also not sure if changing this out would effect the ability to work with a 3ph Tesla destination charger (non legacy mode)

The circuit was copied from one of the commercially sold adaptors with the addition of a 15a resettable circuit breaker to be on the safe side.

Hey guys.

Wondering if anyone can help me on this one.

-I bought a 32a mennekes to j1772 adapter off Alibaba.
-Running a 2012 Aussie leaf
-mennekes end is already shortened
-my gen1 leaf j1772 port accepts max 15a
-works fine with scheider mennekes charger to this adapter to my leaf.
-doesn't work with a 3phase Tesla hpwc. My leaf beeps once on j1772 plug in but no leds blink or light up at all to indicate changing .

Cracked open the mennekes end to find a 220ohm resistor, would it be worth replacing with a 1500ohm?
