EVs have giant batteries - they can be connected via their DC ports and charged/discharged via solar inverters - technically. The current spec for CCS and NACS doesn't allow for this (Chademo did, but they lost the 'format war'). Giant effing oversight on manufacturers' part if you ask me.
Some people have managed to trick their cars into reverse charging via solar hybrid inverters and some custom hardware and it works as advertised - which is no surprise since its a lithium battery charge controller charging/discharing a solar battery.
If you could use your 60kWh EV battery on top of the 10-20 kWh you have at home, it would be a game changer, most people could power their homes for a week on that sort of capacity.
Replacing all the road vehicles in the US with 70 kWh BEVs would mean their battery capacity would equal about 40 hours of the average US grid power consumption.
BTW, this will mean that EV charging is going to have to have variable rates, or else people will just ride over Dunkleflauten by charging up their EV at a charger, driving back, then using it to power the home.
