The Prius is a highly sophisticated system, much more sophisticated than
you're giving it credit for.
Plus, B gear does not charge the battery. Period. End of sentence.
Stop right there. Do not ask questions. B gear does not charge the

Mine does. At least it adds bars to the display.

The rate of the charge done in B mode is *less* than the charge done
in D with foot on break.
Nevertheless, once charged, D mode rely directly on real break,
whereas B still rely on running the ICE in compressor mode.
When the downhill is long (mountain size), B mode is interesting: it
avoid heating the breaks too early.

The first time I used B gear on a long downhill was driving east from
Yosemite park on Highway 120 from Tioga Pass to Lee Vining, a drop of
about 3000'. My 2008 Prius held a constant speed without needing any
foot braking until the battery got fully (as full as the Prius allows)
charged. Then the engine sound changed, as though it was speeding up,
and I had to use foot braking.
Perhaps your Prius does not charge its battery in B gear, but mine does
and apparently so do those of the other Prius owners. If your car
actually does not charge in B gear maybe you should have it checked out
at your friendly Toyota dealer.
