Residential J1772 Stations

[jomo25]

Not that this thread was seeing lots of action, but I don't think it should have been moved. The point was to get a list of J1772 residential EVSEs that have been confirmed to work or not work with the MS.

E.g. I would NEVER have known that the Leaf EVSE wouldn't work for the MS. And consequently could have been screwed for a while since I was going to rely on that for a few months to charge. Knowing that,I'm accelerating my purchase of another EVSE.

So, I think it does belong specifically in the Model S charging sub forum.

Twin chargers can take 80 A max. If you want more, such as 96 A, then it is time to start a "open DC charger" project using the J1772-DC protocol.

Not to mention J1772 AC spec is max 80A anyway (96% duty cycle on the pilot signal, with anything greater regarded as an error).

@ Lloyd - Thanx for the eBay tip!! (cs-60 refurbs). :smile:

Has anyone installed a Siemens Versicharge and will it work with Model S.

 

[wycolo]

Regarding the Model S it would seem somehow inappropriate to call it an UPGRADE if it is simply modifying a 15 amp charger from 120 volts to 240 volts, still at 15 amps! The MINIMUM EVSE for the S would be around 7 KW which gives a full recharge in ~9 hours. Anything less becomes *painfully slow* and likely to impinge on the usefulness of owning a Model S.

Sorry if this has been asked and answered, but I just picked up my car over the weekend and am plugged into our 30 amp EVSE (for our Chev Volt) at work.

Everything is working, light is green etc., but I'm only charging at 15 amps. Any ideas why this might be?

Is this a Volt specific charger? If so since the Volt charges at 15 amps they may have limited the pilot signal. I believe the first generation Volts and Leafs only had a 3.3 kw charger.

I was going to take a picture, but it's pouring rain right now. The Volt is a 2012 model year, and the EVSE is whatever the dealer and/or Chev recommended. I do know it's connected to a 30 amp breaker.

You may be right about it having a fixed limit, but 15 amps continuous (16 amps, actually) could be supplied from a 20 amp breaker. I'll have to take a closer look when the weather clears up a bit.

I bought the Tesla HPWC. Is anyone developing a Tesla source to J1772 adapter? Would be a nice thing to have for guest...

Did you check to make sure your charge current wasn't limited in the charging screen?

I've seen 16A pop up on EVSE's that were limited, but never 15A (it would make for a weird circuit size considering continuous loads).

Volt uses a Level 2 charger. 240V. Volt SPX units do charging at 240 volts – 16 amps. SPX unit also supports charging up to 240volt at 30 amps, but no use for a Volt which is limited to 16 amps. Hope this helps.

I'll check next time I try it at work. All I did earlier today was plug it in, verified the green flashing light and then ran in from the rain. I noticed the 15 of 15 amps thing on my iPhone in my office.

Just to contribute to my original question. The GE Wattstation (residential version) works fine with the Model S.

I built a 75A OpenEVSE, and bought an "extra" J-1772 to Tesla adapter, I use it everyday to charge my dual charger Model S
Unfortunately Leviton no longer sells the 75A J-1772 cables, so the cost to build one has gone up now, about $730 or so.
The advantage is, you can charge a Toyota RAV4EV at full capacity (9.6KW), a Model S at 18KW, or any other lower current EV such as a Leaf, Volt, PiP etc

Seems like we have confirmation that the existing SPX J1772 EVSEs do NOT work with the MS.

Model S with SPX Power Express

Have any of you guys tried the Schneider EVLink (the home wall mount Schneider - EV Link (Wall) | Plug n Drive) on a model S with J1772 adapter?

Thanks

I would be concerned about continuous use that you might need with the Model S. They only built it for several hours of use per day! From their brochure:

Schneider - EV Link (Wall)

Schneider Electric’s indoor electric vehicle (EV) charging solution should be mounted indoors by a licensed electrical contractor. Our EV charging stations are specifically designed to withstand several hours of use on a daily basis. Advanced versions feature intelligent communication and smart-grid integration options.

Sorry, no specific experience with this station. BT I don't see any reason why it wouldn't based on spec.

Lloyd, I'm confused by your comment. The quoted part of the description is a feature, not a limit. And honestly, 'several' can mean say 10 hours. And that's more than it would take for anything other than a full range charge for an 85 with 7.2kW.

 

[Lloyd]

I guess my point is that if they have to tout that it is able to run for more than two hours, I would not be very confident that it is able to run with continuous operation, which it should be able to do.

They should definitely rewrite the marketing message..... Anybody tried the Schneider EVlink with Tesla S? Going to buy one real soon before my local deal for that is gone....​
