More importantly, phevs with an ev mode that are intended to be driven as an ev for a significant portion of their miles are devalued by battery degradation in a similar way to pure evs (because of you pay all the cash for the expensive phev systems,you don't plan to be forced to use it as a plain hybrid).
All EVs are only capable of running on electricity for a limited distance and limited speed. Eventually they all run out.
IMO an electric vehicle is a vehicle capable of run with electrical motor's in any condition. So a modern hybrid-series ship is actually electrical because it's propulsion is electric only, parallel-hybrid vehicle are not electrical since they can't really work only on electrical motors except for limited usage.
