OpenEVSE - Open Source Charging Station

[davewill]

The answers are Yes and Yes. You could definitely do this. There is a large installation in the LA area that does this with OpenEVSE based units. I tried to find a link for it, but couldn't.

Free Destination Charging: 50x L2 80A Stations @ Caltech, Pasadena, CA
There's a mix of technology used there now, not sure how much is OpenEVSE units.

Thanks for that link. It's a awesome thread that I somehow missed altogether.

I know the Open EVSE supports changing charging current via the serial interface (and by the UI), but can this be done in the middle of charging? Or does it have to stop and re-start?

And will the leaf respond on the fly and lower/raise current? I've been thinking about whether Open EVSE could be used to make a dual charger for a single 40A line and negotiate current between the two of them. Or possibly sharing a single 40A line with a garage heater (so when the heater is on, lower current to 14A or something).

An arduino can be programmed to send RAPI commands to the OpenEVSE (OE) based on measured currents with a Hall effect or clamp ammeter on the system that you want to control. The Leaf's system will definitely allow on the fly changes of the amp settings of the OE. I measure both voltages and amps of my solar system, then set the OE's amperes based on the calculated solar production (by the arduino).

Hi. Does anyone know if this project is shutdown?
I'm trying to get in contact with someone...anyone over a placed, but I've been unable to reach someone. I gather OpenEVSE is run by a single person?

OpenEVSE is basically one hardware person and lincomatic and several others for the firmware.

Chris Howell's store is still open. The list has been slow though.

Thanks. Ordered a kit on late Wednesday, but still hadn't heard anything. After no replies and no one answering the phone, I was starting to conclude I sent money to a dead company/web site. He's now replied; not shipping until Monday...

It is likely that Chris is on vacation. I understand it is really a one man shop. He has converted his house into a shop. He provides good support but he is only one person.

Hi Glen
i sent you a PM about an issue im having with an EVSe Unit.
cheers

Below are the quotes I received from Dostar earlier this year. In my experience, these quotes are usually net of shipping. Unless you are ordering a larger batch, which could be anything between 10 to 30 pieces, they will want to send it via air. Dostar quoted me 4.5 kg worth of air freight via UPS at $113. Any customs charges would be on top of that.

I believe that the only economical way to get this done is to place a group order and use ground shipping. I provided Kevin Sharpe with several vendor leads, but based on his earlier comment, I imagine that it turned out to be even more expensive, if not plain impossible to get these plugs from a major vendor like Yazaki, REMA or ITT Cannon.

The BMW ActiveE is the very first EV I ever drove. It was pretty impressive! The guy who let me drive it works for Boeing.

I searched but couldn't find an answer....

Can someone tell me the current rating of the J1772 cord/plug for the Nissan-supplied, portable EVSE that came with a 2017 Leaf S ?
PN is 29690 3NF2E.

I'm building an OpenEVSE and want to know if I can cannibalize the cord and handle from the portable EVSE that came with the car. TIA.

The cable has gone from #12 conductors to #14 on the 2017 units. #14 is good f0r 16A

Ebay frequently has used 30A cables for under $100. I just purchased a 40A cable for $119 Shipped. I will make up a 40A unit.

You can always get a 30A cable new from Ross at TusonEV f0r $125 plus shipping. For a bit more you can get a very small cable from Quick Charge Power. I think a used cable is your best bet.
