Thanks for sharing this. Very interesting and a little surprising. I love my phev and keep it charged as much as possible because I notice acceleration benefits, pre-conditioning benefits, and obvious fuel savings, as well as time saving not having to gas up. I also have no fears of battery discharge like I would with full electric. I live in the states and charging stations are still pretty rare outside major metro areas and a lot of things are pretty spread out here so I still find full EV unfortunately a bit impractical. I CN imagine anyone not charging their phev whenever the opportunity presents.
