On the day of a blackout, a trial of vehicle-to-grid technology proved both the capacity of electric vehicles to support grid stability and the importance of exactly when vehicles are charged.
I wouldn’t want my vehicle to be drained of energy as an event like those started
In the long run there would be ideally thousands of EVs and home batteries working together, such that no particular battery would be drained but contributes a little to the whole. But individuals could make their own tradeoffs on this, if they prefer making more money over the risk of draining their batteries (as prices are likely to be extremely high during shortages, assuming the individual is exposed to the wholesale market). Ideally, these tradeoffs could easily be controlled by a non-technical user and fully automated, but it’s still early days.

This type of analysis and process needs to be carried out before I, an I assume others, will be comfortable participating.
