Chademo has a 2 way capability and Soul 2016-2019 can do this. the problem is the V2G units are ridiculously expensive. I want to use my car as a backup generator but the whole system is prohibitively expensive. You can AliExpress a V2L unit off Chademo but not rated for high wattage. Kind of like that connector for 120V on modern Kia EVs. expensive once again and with no support due to China direct etc...
