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

Peak demand for power is late afternoon, that is when all the AC is on.

EVs typically charge at night, and are incentived to do so by lower rates. Nighttime consumption by EVs is still tiny compared to afternoon consumption by ACs.
