The challenge with using EVs or even residential batteries for grid backup is that grid storage would wear out those EV batteries. When I'm looking at the likely life of an EV battery based on miles traveled, ok, it should last a decent number of total miles. If part of grid storage, that could wear out a typical EV battery in 3 years. LFP batteries might get you 8 years under that load. Not great.

Also, the range of the car after being plugged in as grid storage. Either you guarantee a decent range, limiting their usefulness as grid offset, or you are screwed.

EVs could make for awesome home backup power to cover complete grid outages, but only if those are fairly rare. Daily cycling of NMC and LFP will noticeably degrade the lifespan of the battery. Maybe the power company could compensate for the excess wear or something, but it's not a trivial matter.
