Sustainable Garage Wiring: Electric Car, Conductor Cross-Section

What conductor cross-section would you use for future-proof wiring in the garage? So far, a 16A CEE socket and several 230V sockets are planned in the garage.

If an electric car demands higher requirements, I wouldn't buy it. Maybe a second (independent) 16A CEE socket is a good idea (double garage? second car in the driveway?).

If an electric car demands higher requirements, I wouldn't buy it.

But that is a contradiction.

The problem with electric cars is the range. A "good" electric car is good when it has a long range.
Range is essentially influenced by the battery capacity. Bigger battery = longer range. A battery can be as big as you want - if it is empty, it is empty. So you have to charge a battery. The charging time in turn depends on the battery capacity as well as the charging current.

What good is an electric car with a theoretical range of 1000 km if the night is not enough to fully charge the car?

This problem already exists with the current generation of vehicles. You can plug the car into a normal power socket, no problem, the only question then is when the battery will finally be full.

That's how it is. If you want to be mobile again in 2-3 hours, a fast charging station is needed. Before the provider gives their OK, a few criteria are checked. Since the 15 meters will probably not be laid as an overhead line, a cable protection conduit is required; it can possibly get warm at 32A and 4 square millimeters. It's borderline. Either the system's maximum power has reserves upwards and it works well, or the provider says less than 6 square millimeters is not allowed. You can't know that now. Normally, 16 square millimeters should be laid to the meter cabinet.

The connection between range, battery capacity, and charging time is already clear to me. Nevertheless, I maintain that an electric car will not come into my house (and in my opinion also will not prevail in the market) if it requires super-special charging technology at home.

In the vast majority of practically relevant cases, you also have the entire night at home to charge. Even those who drive 1000 km a day will rest overnight first ... (And if that is not enough to charge the car, then the car is unsuitable.)

Who cares much about charging technology in new buildings? You just plan it in and that's it. According to your logic, neither the car itself - which even requires special buildings - nor home automation or Ethernet should have become established. But all of that is a no-brainer nowadays. You just plan it in and that's it. And especially laying a cable with as large a cross-section as possible into the garage is no big deal.
