Apologies if this has come up before, I scanned recent posts and did some searches.
I have noticed when driving my 2016 C-MAX Energi that after the plug-in battery fully discharges, the dashboard indicator switches to the smaller image that indicates the hybrid battery level. It never switches back to the plug-in battery symbol until I shut it down and use the recharger.
My question is, when the hybrid battery fills up from regenerated power during operation, is the hybrid regen system capable of recharging the plugin battery as well? Or does any regenerated power go to waste after the hybrid battery is full?
This thought occurred to me recently because there's a very long downhill stretch when one drives from Asheville and Raleigh. There are multiple signs warning about using low gears to avoid overheating the brakes, and pull-off safety barrel traps for runaway vehicles.
I had a 2nd gen Prius some years ago, and the only time I ever heard the hybrid cooling fans fire up was when I was rolling down those hills.
