Weekend(s) Project - DIY EVSE

Chris,
When will the kit be available?

DIY EVSE goes Open Source... http://code.google.com/p/open-evse/

Great job.

Chris:
Good decision; Tnx for going open source.

Wonderful to hear. Thanks, Chris.

It would be great if someone packaged a parts kit with a circuit board. This is kind of like how Arduino started.

I think there are multiple companies out there now that do low volume circuit boards for cheap.

Then a parts list is as simple as providing a list part numbers (and compatible alternates) and links to digikey or similar.

Yep... I use DorkbotPDX, but have also used Batch PCB.

I will be adding Wiki pages for both a parts list and PCB production to the Open EVSE page very soon.

Parts list is up, comes out to $12.02 plus the cost of the board...

I'd love to know where you got a J1772 connector and cable for that!

:lol: You got me... I wish that included the J1772 cable.

FWIW... I found this connector and cable. I thought it might be helpful information.

The activity has been moved to a new thread titled "OPEN EVSE" You will find connector info there.

 

[jimcmorr]

Yes. Thanks I found it. And realized my info was redundant.

CAUTION: The J1772 linked to 3 posts above MIGHT be
just fine, BUT:

It LOOKS LIKE one that got stuck ON a friend's LEAF and
was VERY difficult to get off - one that had a full hood
over the locking lever (LOOKS LIKE this one), and which
APPEARS to have a very small locking "hook" (not requiring
or allowing very much vertical motion of the "hook" to release).

NICE PROJECT Mucho THANKS, Chris !

I've been following the posts here, but just now started looking at the project page. First file I downloaded was "EVSE 75A.pdf". Immediate comment ( maybe I should hold my comments for other suggestions ... but here goes ): In the "NOTES" section it says

Circuit Breaker must be rated at least 20% higher than the max EVSE current.

That should read

Circuit Breaker must be rated at least 25% higher than the max EVSE current.

since we always say draw 80% of breaker rating, and 100%/80% = 125%.

Also, the grammar in the first Note ( "Fuses rated 300V current ..." ) is awkward ...

HTH,
