Don't know about the Prius specifically, but the Insight does get all its electrical power from the motor/generator. It charges the 144 volt main battery, then a DC/DC convertor shifts some down to 12 volts (actually around 13.6, to keep the small 12 volt battery charged) to run the standard electrical accessories.
