There’s this company. I don’t have any experience with their products but the concept is promising.

So far, we've just done PV to battery inverter to AC charger to car. less efficient, but less trouble. We've also setup dedicated charging outlets/ circuits on relays to prioritize the house battery.

I'll be curious to hear if anyone has a solution, but my bet is that you need to give the EV a deep well to pull from (probably deeper than a battery bank or PV array can directly and consistently satisfy).
