We are now getting email requests for kits/parts, etc. Sorry people, we do not offer kits or parts. There is simply too much liability for this, and some A**hole will sue us and that will be the end of our assistance to the EV community. Please do not email us asking for assistance with this, we are far too busy as it is just trying to help people get an already-assembled low-cost charging solution.fotajoye said:You may want to contact evseupgrade.com and see if Phil can make you a real, build, deal.
Ingineer said:I applaud Chris for his efforts and am glad this project exists! If you are qualified to construct a DIY EVSE, then more power to you (or literally to your car!), but please, if you don't have extensive experience with electronics and high-voltage, please don't take on a project like this just to save a few bucks. It could cost you or someone else their lives, and if news got out, even that there was a little smoke involved, the negative publicity could really hurt our new burgeoning EV movement!

Keep in mind, by the time you spend $20,000+ on getting your UL listing, and all the NRE and one-time charges, such as injection molding tooling, you have to spread these costs out over your sales. That's why these units are so expensive, not because these companies are greedy.padamson1 said:While it is nuts that companies are charging so much for what is simply an extension cord with some safety smarts, it's not worth endangering your warranty, possibly frying your LEAF and/or yourself just to save a couple 100 bucks!!!

I have an excellent design for a simple, durable, and portable all-voltage EVSE with excellent features, but unfortunately it quickly falls victim to all this business reality when we realize that we could only sell a few thousand units at best over the next few years.

Interesting discussion, and nice looking EVSE design, Ingineer.fotajoye said:Thanks for the info; what can Carbon World do for the forum members, pricewise? What units would you recomend?

This is the basic idea...

I've been looking this for a bit and have a few random comments and questions.
Besides replacing SMD components with thru hole components, are there other differences between the board layout in Open EVSEv1 TH.brd and the boards in the photos?
Has anyone made boards from the .dru yet?
I haven't played with EAGLE much yet so I might just be confused, but it looks to me like most or all of the GND traces are missing from the layout.
Why not make the .sch file available, too? Or the whole project? That would make it easier to make changes
Why not put the EAGLE files in svn and just have latest official "releases" in the Downloads section?
Any plans to add GFCI to the board layout? If I had a .sch to work from, I'd do that
The surge suppressor (TVS) is missing from the parts list and the value (P6KE16A) is missing from the schematic w/GFCI. It is on the schematic w/o GFCI.
Nice.chris1howell said:This board has a +-12V DC\DC converter added so all thats required to power it is a 12V supply.
