Oh yeah, it surely doesn't have a mains transformer or it'd be enormous! It's a switch mode supply with PFC. You could even supply it with DC voltage. I would test it out in a heartbeat, but I'm sadly too dumb to figure out how to fire up EVSE on DC. It's current detection circuit have to be modifi...

I'm charging my cars (Kia soul EV and verity of Nissan leafs, from 2011 up to 2020) without any issues on modified sine wave. Biggest problem is a start up, but after it started up it works without much issues. Even my inverter is "5000w" unit, sometimes starting a regular 1250w EVSE can b...

Where is a way to get a Gerber files for this PCB?

Now in the diagram you will see the lim (charge controller) A250*4B pin 5 is called U_HV_DC which seems to be the measured hv on the charge port via that little extra board on the back cover. Yes that's right. I thought of a small circuit that takes over this voltage measurement. Maybe you can see ...
