true.

As for needing charge- unless 6 bars are showing and have been for awhile, there's 'always room for one more' from my experience. Its very hard to even get to 6 bars without a lot of stop/go braking, nevermind keeping it up that high. My vehicle seems to take a charge as greedily at 5-6 bars as it does at 3, but I don't know if that is strictly true. Below 2, the car will charge even more frequently- staying in 6cyl mode longer, for instance, to provide power to regen for a few extra seconds.
