that Level 2 charging at home is adequate for most owners
In UK our basic wall socket is 13A 240V, which is about 6 MPH charging speed, so even that basic facility will get me 70 miles in 12 hours. My more specialist wall-charger is 22 MPH, so I can charge from 0% to 100% in 10 hours. In practice few are the days where I need to leave with 100%, and its a bit of a squeaky-bum moment to get home with 0%
so arriving home less than 10% is rare.
Someone on the go however that needs access more than anything else
I had those sort of thought before owning a BEV. I can do 220 real world miles on 100% charge. I, now, charge to 100% if my journey is more than 160 miles - risk of foul weather (torrential rain is worse than cold / snow), or detour, or "Can you just pick up ..."
I drive more than 220 miles in a day one or two days a month. I very rarely drive more than 300 miles (in a day). An 80 mile top-up at supercharger is less than 15 minutes, so by the time I've had a pee and got a coffee the car is ready. Or I can sit and do emails, which I would otherwise have to do on arrival, so just time-shifting that job. Family / young kids (apart from the pee-stop) and a long multi-recharge road trip is a different thing though.
Important to me is that I have range to get TO Client / Destination AND back to Supercharger. I don't mind a delay on the way home, but outbound (Supercharger busy, or pair-charging at reduced rate) means its harder to predict arrival time.
In ICE days I spent over 8 hours a year refuelling ... now I spend less than that at Superchargers (and 12% of my annual consumption is from Supercharger - so its a "reasonable amount") , and the time is more usable (I don't have to stand-and-pump-gas). Of course each individual stop is longer - but if I only need 25 miles of extra range, to get home, that 5 minute stop is the same as an ICE refuelling stop.
And unlike ICE I leave home with a full tank, every morning. No Weekly Fill-up
So a high mileage driver who does less than 250-ish miles a day (assuming a 100kWh battery) , most days, won't need any road charging on those days, and should be able to charge overnight relatively easily.
A difference is that I have to plan my longer trips; but once charging points are more widespread that won't be necessary as, as is the case with ICE, I will be able to go to the "one nearby" when I need to charge.
