I think you are on to something here. But it would mean that sentiment could change on a whim: a serious blackout somewhere in Europe that makes continent-wide headlines, and EV demand might crash.
Given the lack of blackouts around here, I've not bothered to investigate if home PV systems can still charge batteries, or if the inverter dependence on the grid for phase-locking the AC prevents that.
There's already been news stories about people powering their homes from their EV during blackouts, the oldest example I know of this from 2012 albeit with a hybrid and it was burning petrol: https://cleantechnica.com/2012/11/10/man-lights-house-with-t...

The technology is called "islanding mode". It adds a little extra cost to the inverters, and you have to specifically request it, but the tech exists.
