Having said that, the only people no supercharging would affect are those with only the use of BS1363 plugs...funny that.
After tapering down a project, I am looking into an 80Amp EVSE with IEC 62196 for my sister's garage in Hong Kong. Reading the wiki page gets me more confuse on the number of types that are available for IEC 62196. A friend of mine refers me to Dostar supplying SAE J1772 Type 1 to IEC 62196 Type 2 EV charge plug, View J1772 to IEC 62196, Dostar Product Details from Zhangjiagang Uchen Technology Engine Co., Ltd. on Alibaba.com
My plan is to either
According to the above webpage, it's cable of 16A/32A/70A @240V charging. Anyone here know of a 80A 62196 assembly for purchase?
- DIY 80Amp OpenEVSE (need to source an 80Amp contactor) and wire an IEC 62196 cable and plug assembly; or
- Purchase of a 80Amp EVSE without the J-assembly and do my own wiring using an IEC 62196 cable and plug assembly
- Nevertheless, they are testing 3rd party mobile connectors and might comment on their use at a later stage
Here you go. A commercial portable charging system that plugs into the Tesla and provides a British BS1343 plug interface:

Yes, I posted the wrong URL. I do need a 62196 male to plug into MS's inlet. Thanks for pointing this out.That's a type1 to type2(male) cable - neither end of which is useful to you when interfacing to the Tesla. You want either a type2(female) plug on a captive cable, or you want a type2(female) panel-mount receptacle on your EVSE and use a type2 male-female cable (which you probably want to carry in the car for use at public charge points anyhow).
I see. I now know to get a 3-phase EVSE (GFI on all legs/phase) so to charge the MS in 3-phase. Thanks for the info.There's no such thing as an 80A 62196 connector/cable. They typically come in 16A, 32A or (rarely) 63A, single or 3-phase. For a Tesla with twin chargers, you normally want 32A 3-phase (ie. 4 current-carrying cores in the cable and 4 current-carrying pins on the connector).
32A@380V 3-phase would be 21kW. This will make me happy. Yes, OpenEVSE 3-phase is now my plan. Thanks for the clarification. Much appreciated.It is not at all clear how (or if) Tesla achieves the 80A single-phase capability claimed on the spec sheet for European cars. According to IEC62196 (I'm reading the BS EN 62196-2:2012 version), the 63A 3-phase connector is rated for 70A single phase, and the single phase configuration uses only 2 of the 4 contacts (presumably the rating is based partly on temperature rise and so you can afford to drive two of the pins harder if you are not using the other two). However, this doesn't appear to be how Tesla is using the connector: it is believed that the car has in effect 3 separate chargers, one per phase, and that the UMC when used with the blue adapter achieves 32A single-phase on single-charger cars by simply wiring the phase pins in parallel - the car doesn't care whether it gets 3 separate phase inputs or 3 inputs all the same phase. As the cars as they are built at the moment, it is reported that you only get 32A (temporarily reduced to 26A) on a single-phase EVSE wired according to the standards if you have 'dual chargers', and 16A (temporarily 13A) if you have 'single chargers'.
Since the 80A capability is outside the standards (ie. Tesla-specific), one possibility is that it relies on the fact that the car-side connectors are not in fact IEC62196 - they are Tesla's proprietary connector with longer pins to allow supercharging, while remaining interoperable with standard connectors. So Tesla could build an EVSE using the Supercharger connectors and achieve a higher AC rating (though you would have thought that they would rate this at 32*3 = 96A to match the charger rating when used on 3-phase). Or possibly the 80A is just a carry-over from the USA spec sheet and Tesla haven't yet determined how they are going to deliver high-current single phase.
Anyhow, either of your plans look like leading you into uncharted waters....
The only straightforward options (whether OpenEVSE or off-the-shelf) are single phase up to 32A (7kW) or 3-phase for any power higher than that.
The US version of Model S (at least the one I have), with the latest SW upgrade, redeuces the current (amperage) if it detects overheat while charging.It's interesting how this unit monitors the wall socket plug temperature and protects the system. Why on earth can't Tesla do this? It irks me that they are not going to provide one of these.
