You leave your car parked outside at a slow 22kW charger. But with a full BEV, you don't need to charge every night, just like you don't need to fill up your gasoline car every evening in your own garage.
Not just like. I can fill up my car in 5 minutes and it lasts 1-4 weeks. That's why I don't need to fill it up every night.
That's not the case with PHEVs, or even, I believe, BEVs.
