High Power Charger vs. J1772

So, the EV Project will be installing a ridiculous amount of public J1772 charging stations everywhere -- many where I live, SoCal.

It seems like J1772 will be the standard, including Teslas (any word on the Model S?)


I just got my Tesla :smile:

Should I wait for the J1772 tesla conversions or install the high power connector in my garage? At the moment, I only have the NEMA 5 connector.

Many people with HPC's find they rarely use the high power charging at home. At home most of the time I charge at 24A (240V) overnight.

I would suggest waiting For J1772 because I think the Tesla connector will only be found on the Roadster.
 
Elon told in Milan
with respect, I do not believe we will ever see 3-phase support on the Roadster provided by Tesla. I'm also willing to bet you $100 that you won't see 3-phase support on the Model S from Tesla before the end of 2013 (if ever).

I'm not opposed to 3-phase and would love to have it when traveling in Europe. However, with connector standards still trying to get established and with Tesla's US focus I just don't think this will happen any time soon. That said, I'm sure that after market 3-phase solutions will be provided as cars start coming out of warranty.
 
JB Straubel promised to me to provide 3-phase charging for Europe. I think Tesla will support the Mennekes socket. a vienna-rectifier is cheaper, compact and more powerful, creating less noise compared to 1-phase high current rectifier, which needs more coils and caps.
 
Eberhard, though I agree with your sentiment (and I'm sure many others do), please stop hijacking every thread that mentions charging into another 3 phase discussion. It's unfair to the original poster and annoying to other readers since it is clearly not relevant here.
 
Back to the OP:

I put two Nema 14-50s in my garage ( 240V 50amp, max continuous current 40 amps ) and I charge my car exclusively with a mobile connector.
When I get my Model S, I plan to charge it via a mobile connector plugged in to the other Nema 14-50 outlet.
That is what I would recommend.

I have never in the year and a half of owning the car needed to charge my car at home faster than 240v 40amps can do.

I wouldnt invest in an HPC right now until we know how Tesla is going to solve the J1772 connectivity problem with the Roadster.
 
Even a 10-30 outlet in the garage will do (full charge overnight, not that I've ever really needed it). I was lucky - the laundry room is on the other side of the wall, so I tapped into that circuit and use the mobile charger. About $40 in parts (over the mobile charger) and about an hour of time (it's hard wrangling 10 gauge wire in a single-gang box - if I had to do it over again I'd go for the double-gang just for the room).
