I believe that hybrids such as the Prius DO bump up the voltage internal to the system.

For example the battery pack may be 144V, but goes up to 300 some for actual use in the motor. I am not sure of the exact reason why this is done.

I think it has something to do with how AC motors work, and possibly have to do with the regen braking as well.
