> The battery of a PHEV is relatively small and will be strained much more (as compared to an EV), especially if you drive a lot in EV modus. PHEV batteries tend to wear out faster for this reason. This drives up cost of ownership.
With appropriate battery management, this doesn't really drive up the cost, it just moves the depreciation curve around.
Think of it from the other side - with an EV, you're paying up front for a bunch of battery value in a consumable good that you'll never depreciate.
Toyota did a study and found that pretty much no one who owns a PHEV ever plugs it in. I know you qualified with with "proper battery management", but the reality is most people will be lazy and cannot be bothered.
Er, yeah, but that's an entirely different problem than the one I was commenting on. If you never plug your PHEV in your battery will last forever since it will take ages for the capacity to drop to where it no longer functions as a sink for regen braking.
