Time required to charge might
Time required to charge might not be the right metric to worry about here. Last time I left the state as a hurricane approached, the last Supercharger on my way out of Florida had a backup. I had to wait maybe five minutes before a stall cleared up. The first one in Georgia had a backup, as well.
Less-often talked about is the infrastructure required after the storm passes before folks can get back up and running again. An ICE needs a tanker truck to delivery fuel to a gas station (and enough of it to satisfy the needs of the local community. at that), plus power to run the pumps, EVs need only the latter. For that matter, an ICE needs fuel delivered specifically to a gas station. An EV can plug in anywhere, even a tiny 110V outlet outside a donut shop in a pinch.
And those overcrowded Superchargers I encountered when I left the state? Nobody had to drive a truck out to keep them supplied. They run 24/7, unstaffed, so long as there's juice.
