Prius Problems- get used to it- I have no idea about electrical problems in these electronic nightmares- but SOMETHING must charge the battery- and you SHOULD have a really good mechanic who can deal with this machine-

There is a motor/generator. I would say depending on your mileage that you might have bad brushes on it. This can happen if you have driven with a battery that is bad; one that requires too much current or voltage to pass. This causes arcing and burns out the brushes. This is just a guess, as regular cars have this problem, and I am new to Prius's.
