Not too often here; If I descend a long grade with the brake pedal lightly depressed, I can get it up to a full charge; that being said, when the battery is fully charged and you are still using regenerative braking, the computer will put the engine in 'braking mode' which is a lot like moving the level into the "B" position. There are mixed messages all over the web; my belief is 'b' shifting actually uses the battery to spin the engine up.
I usually get a fully charge on the same descent on my way home from work. There is a very steep descent over about 1.5 miles.
