RUKI: @dolsen re:PHEV - IMO it has to be the same as Petrol and Hybrid - charged at the pump.
Here is yesterday' case: Lady purchased imported ZVW35 2012 Prius PHEV. 11 year old PHEV which, in her case runs only 8kms on a full charge, but their daily usage is much much higher. So her EV portion is negligible and she'd be running on petrol 99% of the time
Seems ridiculous to actually buy a PHEV with that little range. I mean, buy virtually any other car.
