    Believe it or not, I thought the same thing after I wrote that. The more they confuse the customer the easier it is to convince the customer to buy what the salesman wants to sell. They make a ton of money from confused customers.

    Yep, those silly physics laws of thermodynamics get you every time. There are losses every time you convert energy from one form to another. As Jerry says, there are only some very special cases where it is advantageous to use the gasoline engine to charge up the battery. In HV mode, the system alternates between putting a little charge into the battery with the gasoline engine, and then using that charge to move the car, so it can keep the gasoline engine running in its most efficient mode. When you do a long drive and don't do anything special, you will end up with battery in a low (but not empty) state of charge, with the car behaving like a standard Prius. The only way to fill up the battery is to plug it it in to the wall, go down a long decline, or (in special cases that are hard to describe in a single sentence) manually use the CHG functionality
