What charge port connector?

[slcasner]

An update on the Model S charge connector based on a short conversation with Elon at the end of the first annual shareholders' meeting yesterday morning.

I asked Elon if the Model S would have a J1772 connector. He said it would not because J1772 can't handle high enough power. I agreed that it would not handle the high-power DC charging, but it would handle 70A level 2+, and that I assumed the DC charging would be a separate connector. Elon replied that the Model S would have one connector for both modes. I guess this means yet another proprietary connector. Sigh...

Help me Jeebus...

I don't suppose you thought to ask about support for 3 phase. This was imagined to be promised to a certain someone by a certain Tesla CTO during a dream, European Tesla store opening, and/or spirit walk.

Well if not J1772, one can only hope it would be this.

Without taking this off down the line of another thread...

J1772's proposed DC Level 3 / AC Level 2 connector surely fits the bill. What words did Elon use exactly, because using this wouldn't contradict the last sentence.

The only connector who can handle both is the Mennekes?

I don't understand why they can't just say at this point what the connector will be. It has to be finalized by this point. Not having a J1772 charger on there is a mistake I think. Especially in the eyes of the general public.

Mennekes can handle both.

The Mennekes Combo plug isnt provided for HighLevel DC Charge, 63A AC, 70A DC. The S is 45 Minutes QuickCharge. If i asume the S has 75kWh Accus, that means 100kW power for 45minutes chargetime. At 3x400V thats 144Amps AC.

70A DC x 375V = 26kW > 3h Charge time.

The only connecter now, can handle 45 min. charge is CHADEMO Standard (supported by about 300 companys worldwide, based on TEPCO Tokyo) on DC 50kW, 100kW, 200kW.

BYD has a propietary solution.

Teslamotors may be has not dicided or communicated there solution.

The good info for quick charge: The primary connection to the grid will be fix installation, can be different according the local grid archtecture, for instance 3ph in EU, 1ph in US, J, Italy ec.
The Output is alwas the same, according the car interface.

Mennekes can handle 3x63A = 44kW output or 1x70A AC or 2x 70A 500V DC = 70kW output means 80% of 80kW = 64kWH in 55min. Both is fine for me, but i don't need/want DC

Aw crap. Apparently Tesla sees plugs as their main profit center.

Possibilities for not announcing:
1) They have not finalized their decision/design.
2) They think they have something better than everyone else and they don't want to be copied.
3) They think they have something better than everyone else but believe it will face criticism until they can demonstrate it and prove that.

Technical possiblities:
1) Much higher power than anyone is currently thinking about. What if they are thinking about 100kW? or 150kW? Maybe they believe they can convince the world that 60-70kW isn't sufficient and the Model S will be ready to handle much more power whenever those are available?
If you buy a fleet of Model S cars, a couple of 100kW-150kW chargers may be a small piece of the pie.

Lets hope you are right that the reason is that they have something better. But keeping it proprietary would be a shame as a shared charging infrastructure can help more broad acceptance of EVs. One thing going for gas stations is you know the nozzle will fit your gas car no matter which station you happen to use. As it is now with EV charging, we have small paddle, Avcon, J1772, Tesla connectors, CHAdeMO, and such spread around. I have already seen some Leaf's pull up to the local Fry's electronics having found a charge spot on their map only to realize there are small paddle and Avcon there and no J1772. I have seen Teslas parked in small paddle spots that are marked "EV only" thus denying a Rav4EV a chance to charge. I really think we need to get standardized on one plug for everyone. If Tesla were to offer charging stations with > 20kW what socket would they use? CHAdeMO? New SAE? IEC 3phase? And to add to the above we have different vendors trying to introduce RFID card controls on their EVSEs, so there doesn't appear to be a standard there either. I will need to have a Chargpoint account and RFID card, as well as a Blink account/card, and who knows what else in future to be able to use the different charging locations.

...Regarding charging stations, Musk said that Tesla vehicles' extended range means that the company could cover cross-country drives with 13 charging stations. He said eight to 10 stations on each seaboard could cover the U.S. coasts. At an expected investment of about $25,000 per station, "for a couple million dollars you have covered the country," Musk said...

Is that a suggestion that they plan to have company operated charging locations? Would they allow non Tesla cars to charge there too? Hopefully charging infrastructure is viewed as an industry wide effort, not something proprietary to each company.
