I'd like to be able to charge my 2012 DS off a J1772 socket using the onboard charger and a separate QuiQ quick charger. I tried searching the internet for such a device but I came empty. So I am thinking of making one.

Electrical connections seem simple enough but signaling part is where it gets a bit complex. Wikipedia article on J1772 says I need to generate a pilot signal to tell the charging station to connect power to the connector -- are there any off the shelf components to generate that pilot?

Are there any simpler solutions to what I am trying to accomplish? I am aware of the Zero provided J1772 connector but that one just connects to the internal charger.

From what Wikipedia says, it looks like you could.  The signaling circuitry looks relatively simple; eBay at least has sockets and cables, and a controller board like this one (http://www.ebay.com/itm/J1772-Active-Vehicle-Control-Board-AVC1-/251068357421?pt=LH_DefaultDomain_0&hash=item3a74d71b2d#ht_500wt_1180). It looks DIY-able with a small microcontroller or even a 555, CMOS logic and a few analog components.

One think I'd probably do, though, is use Level 2 (240V) charging, and run both the chargers off the 240V in parallel (the QuiQs will run at 240V also I believe). The Level 1 (120V) only guarantees 16A, which is right at what two QuiQs will draw, based on what my Kill-a-Watt says. Wikipedia says the 240V is split-phase, but there's no neutral, so I'd be hesitant to run the chargers as "stacked" 120V units like you might in your house.

One other thing Wikipedia is not totally clear on is how you tell the charging station what level to use. There is some signaling to let the EV know how much current the charging station can provide, but I didn't see anything about voltage, unless that's implicit in the current values (i.e., anything <=16A is 120V).

I'm sure some more EV-savvy people on here know more. I only learned how to spell "J1772" about 2 weeks ago . And there aren't any J1772 stations within 50 miles of me, so the standard US wall outlet is all I have used.

QuiQ will definitely accept 240v. I think you could run both off the same power bus. Also Google openevse.

AC input 85 - 265 VAC

I run it daily with 230V and it should  have better efficiency (lower AC Current)
