Dont think this feature has been requested yet. However I am looking to purchase a new EV in the next few years one with Vehicle to Home support.
It would be nice if there was a second product one that supported Vehicle to Home. Preferably J1772 like the Ford Charge Station Pro, Personally I wouldn't want to plug in a CCS charger at home every day (like the Wallbox Quasar 2).
Also I do understand that it would require more in-depth install. Because in order to be safe for the grid operators, when the grid power goes off, the connection to the grid must be disconnected.
My assumption is this isn't a product yet because I don't think any EV's on the market support Vehicle to Home yet.
