The standard 110V 15A power available in every home and apartment in America can supply 1.5kW of power. If you leave your car plugged in for 10 hours, that’s 15kWh. A Tesla Model 3 gets about 4 miles per kWh, so that’s almost 60 miles of range. If your commute is less than 30 miles there and 30 miles back, then you never need to visit a charging station, and you probably don’t have to call an electrician to install anything either.
There is a problem with many older apartment buildings which don’t have a power outlet near every single parking space, but that is a relatively simple problem to solve; electricians add and move power outlets every day of the year.
If your commute is longer than that, then maybe you should talk your boss into installing power outlets for the parking spaces at your work, or you can use the 220V 30A outlets that your washing machine and dryer are plugged in to. Those can give you double the range in the same amount of time. Of course, not all apartments have 220V outlets; many apartment buildings get 3–phase power from the power company and then give each apartment just a single phase. That’s annoying, but not insurmountable.
I would wager that the number of people that need more than 120 miles per day is very small. Not zero, of course. I know a guy who drives 200+ miles per day as a selling imported Italian foodstuffs to restaurants, for example.
Edit: oops, 220V 30A circuits can give you quadruple the range, not double. I forgot to multiply. Even my friend the Italian food salesman can make his daily rounds on an overnight charge from that.
- beardyw 4y agoI wonder how these folks will charge their Tesla? https://www.medpagetoday.com/publichealthpolicy/healthpolicy/93695 https://www.medpagetoday.com/publichealthpolicy/healthpolicy...
- db48x 4y agoBy running a power cord out to their car. But if we really do end up going 100% electric, I can see cities setting up on–street charging as a service to their residents. We’ll start seeing parking meters that have EV–charging cables for plugging in your car.
- jleyank 4y agoHope you’re right, as I can see cities making sole-source contracts with companies to providing charging stations where residents can pay for charging their vehicles. Then, the fight will be this vs in home service (think cable vs over the air).
- BenjiWiebe 4y agoI'd be more interested in how they managed to afford their Tesla. I sure wouldn't mind a Tesla but I can't get a working used one for $1,200 like I did with an ICE car.
- db48x 4y agoFWIW, I only used Tesla as an example because I happened to remember their approximate efficiency in miles/kWh. There are less expensive options, and over time the used prices should fall as well so hopefully that is only a short–term problem.
