hello experts,
i am in Canada we have 220v/20AMP (2 phase of 110v (110v--Neutral-110v ) available in the home
i have kia soul EV presently i am using (220v/16A -level 2 ) J1772 charger for daily needs
kia soul EV has battery 360-374V as well CHAdMO plug available, as a 3 phase is not available
i thought if i can use my existing available(input) 220v/20 AMP to moded Prius gen2 inverter and output
is CHAdMo DC-DC 370v to charge my kia via CHAdMO in case of any J1772 issue. please share thoughts , if it possible?
thanks in advance.

Yes, you could rectify house mains to dc. May need some additional filtering beyond just the Prius inverter.

tho the latest Gen2 charger software for the replacement boards has a chademo function. To run a Gen2 Tesla charger as a chademo charger.

The Prius Gen2 inverter as a whole is not the best option. It is normally used to rectify AC to DC via one of the inverter stages and than step down the resulting voltage to battery voltage.
But rectifying 220Vac resuls in 310Vdc, so below your target battery voltage.

You can however use a normal rectifier and the buck/boost stage of the Prius inverter to build your own STEP-UP charger, perhaps by using this software: https://github.com/jsphuebner/stm32-charger

Thank you both of you for the prompt reply and clear explanation, much appreciated
i am following this thread for while as well Demian M. videos, was thinking to buy gen 2 inverter online and order modded board and software from here once both bundles up then i simply input 220v/20 amp and the output will be 360v DC ready for CHAdMO but seems not that easy what i am thinking but gain really good knowledge,
