For sale a L1 12A and L2 40A OpenEVSE with real time clock.

This unit consists of a DIY ver 2 main board, Power supply, 80A rated relay, multi function meter with KWH, blue display board, and a RGB led display board. It has a 40A range power cable with a molded 14-50 plug. The J1772 cable that is from Quick Charge Power and it is twenty feet long. It is shown charging my eGolf.

Version 3 firmware is loaded

This can be a 32A or 40A EVSE. It can also be used on any J1772 car. Tony Williams recommends wiring the 14-50 receptacle as a 50A one although 40A is allowed since there is no 40A parts. For 50A the lines should be #6 and the ground and neutral can be #8. The neutral is not used and if you mark the receptacle EVSE only it can be left out. It really only adds a small amount and then you have a standard receptacle. The breaker should be 50A for a 50A circuit and 40A for a 40A circuit.

I have a female 14-50 wired for 50A that I used for my 40AS Mercedes B EV. The same EVSE charges my eGolf just fine at 30A. The Quick Charge cable is very small since it uses paired L lines, much smaller than a normal 30A cable. In fact Quick Charge no longer sells 30A cables.

This is for sale for $350 plus $25 for shipping. Local pickup near Disneyland is available.

This is sold ASIS but it is working. Payment is cash for local pickup or Paypal if I ship the unit.

I forgot to change the default current. As you can see the eGolf complies with the J1772 specification.

I just build them in my retirement to keep busy. I sell them at near cost since I am not looking to support a family like vegasbrad.

How long is the charging cord that comes with This?
Also would not need a plug since I am already set up for hard wiring since I already have a 60 amp 240 circuit in my garage for my motor home

The cord is the default 20 foot length. I have used 25 foot cords in the past for my Leaf. A twenty foot cable just reaches my eGolf. My Mercedes B EV had the outlet on the other side so a 6 foot cord would work. It really depends on where you mount the EVSE. In my case the panel was outside (common in Southern California) and I mounted it on the rear of the panel. This made for very short wires.

It has a 40A four foot long electric range cable with a molded 14-50 plug(like Tesla uses). The neutral is not used so if you label the socket EVSE only you can ignore it but the wire cost vs the labor cost is minimal.
