Yes it's still true. To charge an EV the average person needs around 10kWh a day, distributed over 23h of parking time. That's not a lot of current. You just need to teach the car to talk to the grid so that not all cars charge at once.

The median driving distance in the EU is 30 km. The electric cars on sale use 15-20 kWh per 100 km. Thus daily routine per median will be 5-7.5 kWh. The current will be even less than the parent’s statement.

I recall a study that if 80% of cars were electric in the U.K., it will increase the load on the grid by 10-20%.

23h? That strikes me as ridiculously optimistic on a population-scale level.

When only charged at home it's just an overnight charging window.

Cars are parked about 23h a day. Eventually most parking spots will also have a charger, because that's pretty much the only way EVs will be adopted in cities where people don't have garages.

I'm not sure how this looks WRT grid limits/congestion, but there's an alternative mass-adoption scenario where battery tech matures to the point of charge rates becoming equal or better than "gassing up" today.

We don't have gas pumps at every parking spot and drivers are generally content with the current situation.

Ah yes, that's of course also possible, but I think it's a lot less likely, because the shift to EVs needs to happen quite quickly, imho before batteries had time to improve sufficiently.

Anyone having charger at home will never voluntarily connect the charger at work or in town unless they actually are desperate for charge.

Why?

Also, most people live in cities. Most people in cities don't have a charger at home.

Most people in cities don't have cars at all. They use public transportation or ride sharing. Parking a car in a city is expensive, especially since you need to park it both at home and at your destination.

Cities are full of cars during the day, but the parking lots empty out at night. They live in less-dense suburbs, where it's comparatively easy to park and comparatively easy to have a charger installed. In the city, many of those who are willing to afford a car at all will also find ways to charge it (including sharing a few charging stations at their garage).

1. It is a hassle with no benefit.

2. At least one but perhaps several orders of magnitudes more expensive than doing it at home. In part because you can charge overnight when pricing is the lowest.

I'd guess most people that have a EV-vehicle have a charger at home.

Both points are true today, but need not be true in the future. If everyone plugging in and charging at 20kW around 6pm becomes a problem (at it probably would be one), then the incentives will change.
