I made one and it has a circuit inside that automatically disconnects if it senses my Roadster within 50 feet and needing a charge.:wink: Trying to disable this feature causes it to detonate.
:wink::wink:
Would it not be more practical to 'upgrade' the HPC's to J1772?I hope someone makes a 'reverse adapter' someday, so, for instance, RAV4EVs could charge at Roadster HPCs, and use a Roadster UMC.

Not so much a bad review of the ITT Cannon parts as much as a sad commentary on J1772. ITT Cannon makes the best parts I've found although quality dropped a little when they started making everything in China. The problem IMO is the SAE. You are correct there is not enough surface area on those pins /sleeves to get adequate contact. It's fine for 32A for which it was designed. Add a little dirt (this is an automotive application after all) which is inevitable and you can't expect to get 75A without getting hot. In fact it already gets warm at 70A even under ideal conditions.> J1772 is also a poor standard for high amperage like 63 or 70. It was designed for 32 amps and later they decided it would marginally work at higher current levels. [hcsharp]
Sounds like a bad review for the Itt/Canon 75 Amp rated J1772 plug. (Guess they make a matching 75 A socket, too.) What, did they get warm when you tested? Just not enough copper to copper in there(?).

I tried to charge at a SemaConnect charging station with the TM J converter and the new one I got from hcsharp (brilliant piece of technology by the way ...thanks) and after 30 sec both caused a ground fault and shut down. It was at a SemaConnect regional headquarters and a super nice Application Engineer named Mike Meall ran out and was fascinated by the new connector. He stared at it for a minute and said, "with this I can fix the problem" then he started talking in a strange language about filter and electrical stuff but was very intent on talking to the "designer"of the new" can " adapter. Sooooo if there is any interest we might be able to incorporate a fix for the CFGI ground fault problems roadster owners have with SemaConnect charging stations be incorporating a small filter into hcsharps new converter. ran the idea past near by Ranger and he said it could be possible. If interested in investigating possibilities of opening up a big charging network to roadsters 1.5 and above let me know so we can arrange a conference.
My Roadster shuts off 4 new Schneider EVSEs after 15 seconds. Yet works fine on AeroViron~~ chargers. We are looking into the possibility that the Schneiders were inadequately installed with, say, 30A breakers or somesuch. --
The Schneider has a 5mA GFCI trip; the Roadster goes a little over that briefly near the start of a charge (but stays well under the 20mA trip level that most EVSEs use). Schneider knows about this, and has a fix running through the UL certification process and will update the units in the field. No word on when, though.
You should NOT simply unplug the J1772 connector from the can because you will potentially interrupt at full power (the car will not detect you unplugging).With the Tesla cables they have the switch to pull back to stop but with the can, what action should be done first?
Turning off the socket from the wall, unplugging the J1772 from the can or unplugging the can from the car?
The switch on the Roadster cable and the 'stop' on the VDS do the same thing (tell the car to stop taking power from the wall)... it does not matter which of these two mechanisms you use.So far I have only used 13amps and so have always had the switch on the cable. I never used the touch screen inside the car to stop charging... Is this bad then?
Ok Great. Here's my Ecotrcity process;Ill be using the ecotricity point at Hopwood services later in the week and will try it out for the first time using the ZCW cable
Dedicated 60A/70A Tesla Charging Stations... no adapter or cable required.Those 70A charge points, are they dedicated Tesla chargers or would I need a 70A rated cable to use with the hcsharp adaptor?
David - Those 70A charge points, are they dedicated Tesla chargers or would I need a 70A rated cable to use with the hcsharp adaptor?
