But in most cases it is very easy to arrange charging when you are not running your electrical dryer or air conditioning, mainly in the late evening or night. It would be trivial to control your charger such that the total electricity drawn by your house connection never exceeds a set value.

A typical hairdryer is about 1KW, it runs for a few minutes at most, similar to an electric kettle. AC units for domestic (normal sized houses) are from 2 to 5 KW, actual use depends on the temperature differential, humidity, the size of the house and any leakage.
Recharging a drained car battery would use as much power as running a large AC unit for 15 hours, but if the car has driven only a small distance it will use much less power. It all depends on the distance the car needs to drive (logically...).
