You would "only" need a regular power outlet in the parking space, since it can load all night. Same for the workplace, though one would probably be enough. Additionally the local grid would need to be strong enough, but this could partially be mitigated with some sort of locally installed flywheel accumulators. A important aspect is, that people in cities are probably going to have fewer cars in the future and will travel more per bike, roller or public transportation, if they don't work from home in the first place. Also keep in mind, that this is only about new cars. So it is not necessary to have power outlets for every car in 13 years, for that it's rather around 25-30 then.

I’m an electrician and usually wire is ran in parking lots for the lighting so why not just lay an extra pipe for charging. Literally just that simple.

A slow charging car uses roughly the same as a running fridge I believe. Do you'd need to make some minor changes to your wiring, but nothing that can't be done.

More like a hair dryer, but it's still easy to pick up 5-10 miles of charge per hour. 50-100 miles of added range overnight is doable for many drivers.

Don’t regular power outlets barely charge the vehicles, like -a few percentages over night, this wouldn’t be enough for people that need to drive daily

The definition of a "regular" power outlet can vary (how many amps are on the circuit, is it dedicated to car charging or is there other hot stuff on it as well, etc).

Also, a lot depends on the size of the car and the amount of travel you expect to do on a given day. If charging overnight on a 20 amp circuit gives you 50 miles of driving (and your commute is less than 25 miles each way), then the "regular" charger may be all that you need.

Technology Connections made a wonderful, long-form video about this exact thing:

I love Technology Connections. He deep dives into such strange stuff and gives it a good honest go to be precise and informative.

Seems like a great resource I’ll have to watch today after work. Appreciate the explanation since I’ve just started looking at an EV as my next vehicle so trying to understand practicality.

The short version is: charging speed matters less and less if your car is plugged in long enough and when it isn't driven far. If you come home with 100km missing even a slow charger is going to fill up your car in the hours you're at home.

Generally it’s 4-5 miles per hour plugged into a 110 outlet. It takes a while if you’re in a hurry but plugged in overnight for 8-12 hours is plenty good for most driving.

don't forget the 220-240 outlets in EU

Great point! It’s nice to have a level 2 charger but it’s not completely necessary. There’s usually a charger near most places we visit and it works out just fine not having a faster charger at home.

Depends on the size of the vehicle, and it's not just a small percentage.

Fun fact: Most of Europe uses 220v for "regular" it shouldn't be that big of an issue.
