I have a PHEV and charge overnight from a wall outlet. I wake up in the morning fully charged. Probably 99% of my trips are electric, but only 80% of my miles. The occasional long road trip really adds up. It is also hard (in the US) to charge on a trip. My car can't charge from a DC fast charger (it doesn't have the right connector), only from the level 2 AC chargers. From a L2 charger it only charges at 3.3 KW (most chargers support between 6.6-10 KW) which results in ~10 miles of range per hour. So if I take a half hour lunch break while driving, that's only 5 miles added.

If you can charge at home or work it's a great deal, but if you can't I can see how it would be hard to charge it enough to make it worthwhile.
