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 can be charged night time to balance the load. This reduces the need to have to use less efficient methods of channeling excess overnight electricity such as steam storage or resevoir pumping.
