Nobody is constantly charging their completely empty EV.

A typical commute of 50km/day at 20kWh/100km means you have to put 10kWh into you car (per day). A 230V outlet can deliver 3,7kW at 16A, so your car would be topped up again after about 3h.

Tesla Supercharger prizes at 20kWh/100km are in the same ball park as Diesel at 5l/100km. Charging at home should approach half that, and charging with PV will amount to <2€/100km.
