Yes of course that would be cool but I don't have that much power at home@Paul G. Don't bother... Brusa 22kW single phase charge rate is 3kW so unless you're always using three phase it's useless...
Better approach is some of the open source chargers that will have 3 phase support at ~43kW soon
Wooww now that is a lot!! Thought it would be around 3000 Euros!!! Thats explains that the lack of interest!!The OEM price for the NLG664 is 6,640 Euros (excluding cables and VAT). Brusa will also require you to purchase a support package for 9,500 Euros (+ VAT). Hopefully that explains the lack of interest in the Leaf upgrade market.
If you want serious AC charging capability in an off the shelf EV then buy a ZOE, Smart, or Tesla Model S/X.
