I know that the car dictates the current, but if I spend the money and put the effort into building an EVSE I want to have the full 40A continuous capability. I am not sure how I will make it work at 120V, I am still brainstorming about that.
If you go with the Chinese relay it has a 12V coil so it will work on either 120V or 240V.
By the way, the 40A cable from Quick Charge power that Chris sells has a cable that is about the size of an ITT L1 cable. Using paired #12 wires makes it very small.
I have ordered half a dozen relays from AliExpress. Just do not give them your main email address since they spam it to death. They cost about $15 shipped. You can also get it from the JuiceBox people but it is $15 plus shipping and sales tax in California. I have got relays from 3 separate companies all with the same part number. It truly seems like a generic part.
If you are local and replace the relay you can have my spare. I try to keep spares so I can support the units I have constructed. So far none have been needed.
