How can the US power grid struggle with ACs in the summer, but be (allegedly) capable of charging millions of EVs once we all make the switch?

Question

Currently we are told the power grid struggles to handle the power load demand during the summer due to air conditioners. Yet scientists claim this same power grid could handle an entire nation of EVs. How? What am I missing?

Answer 1

EVs typically charge overnight. Air conditioning and high power appliances like stoves and dryers do not run during this time period.
