For the last couple of years I have been building OpenEVSE's for others.
I thought I would post the units I use.
This is my main car EVSE. It consists of a Barbouri ver 4.2 main board, A 40A range cable, 20 ft 40A Quick Charge Power J1772 cable, A RGB display with RTC, A neat Chinese multi meter that Craig Kirkpatrick suggested from Ebay, a 90A Cuttler Hammer contactor, 12V PS, MOVs for transient protection, and the GFCI and current coil. This is mounted in a 8X8X4 inch junction box. it is running ver 3.51. I have an upgraded board with 6N139s and firmware 3.9.4 for a someday project. The current version works fine.
You can see it charging my Mercedes B Class Electric Drive
I also replaced the Lear L1 charger with an OpenEVSE unit. I can now charge at 15A on a 20A circuit or the default 12A on a 15A circuit. I store it in an old laptop case.
