The BMW patent shows something that should work, but it is intended as a [third?] turbo to supplement others. So it isn't a total solution.

The problem comes in when you are essentially driving the turbo with the alternator. Losses accumulate. What might be feasible would be to use a conventional turbo to drive a generator/alternator to recharge the battery.
