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

The major difference is that air conditioning demand all hits pretty much at once during the hottest hours of the day, but electric vehicle charging tends to be a slower trickle spread across many more hours. We would need to upgrade electrical infrastructure to handle the extra demand if everyone switched to electric cars, but we need to do that anyway.
