"V2X technology, which lets vehicles feed power back into the grid"
Never heard this before. V2X used to be quite well-defined as a term in mobile communication.
The origin is that it's an evolution of the communication term M2M (Machine-to-Machine), which covers communication where none of the parties is a human (unlike other scenarios where a human is either on the originating (MO) or terminating (MT) end of a mobile connection).
Vehicle-communication was "branched out" into a separate term as it has a set of unique use-cases and requirements --> V2M (Vehicle-to-Machine)
Then it was expanded to local P2P connectivity to other vehicles (mostly not mobile network-based) --> V2V (Vehicle-to-Vehicle).
When it was expanded again to also include local connections to other "members of traffic", i.e. roadside units, traffic-lights, etc., with standards like see IEEE 802.11p gaining momentum and 5G came along as a potential cellular bearer for all of it, it was merged into a single term --> V2X (Vehicle-to-everything).
