It's not at all the same as everyone on planet earth in the same hemisphere trying to charge their cars during peak summer AC time, between 4 and 6ish pm.
Independent of this, plenty of counties use energy to heat (consumes a lot) or have ac which also pulls a lot.
Ev charging is estimated with 10% additional load on a power grid. That's doable.
Is it a challenge? Yes. In one place more than in another place
Why do you keep parroting this nonsense? Virtually nobody charges their car at this time
If you use anything more fancy on the PV side you can also control it on the other side.
And for more than one flat, load control is already available. We're I life we have 90 cars in the parking garage and there is a load controller
