Trust me, the Prius is a regular car.  There's a system inside the
manages the gasoline energy better than anything that's been used
before, but to the outside world it's a regular car.

There's no difference in how an inverter hooks to a 12v battery, whether
that battery is in the Prius, in an F150, or sitting on the ground.

Right an inverter for 201 dc to 120ac wouldnt be cheap. Great idea
setting a larger battery and wiring it up permanently. Without airflow
of a moving car how do you monitor heat build up. I would worry a non
moving car could overheat the generator. I have an IR thermometer ive
use to check small air cooled motors and equipment.

 I have changed "motor" to "engine" to make it clear you are speaking of
the internal combustion engine, not one of the two motor generators.

No.  the 12V battery is used to power all the auxiliaries and computers,
and is kept charged via the 201V traction battery.  The 201V traction
battery is used to start the engine.

Still no.

No.  The 12V battery can run down if you leave lights on (for instance),
and since it is a small batter, much more quickly than a 12V battery
would run down in a conventional automobile.

To power computers, heater fans, radio, clock, lights, and all of the
other items normal to an automobile other than the hybrid system itself.


What components?

This isn't even a question.  If the 12V battery has power, the auto
turns on.  If the traction battery is so low that it can't start the
engine, the auto won't move  If there's enough power to start the
engine, it will recharge the traction battery.  The traction battery is
always kept with at least a partial charge, so the conditions of your
statement will never occur.

It's not built into the car, but surely a good electronics person could
build something--or maybe some third party product will do it.  Anyway,
it's not built into the car.

It has been done, and evidently, the Prius can typically handle about
1.7 kwh when properly set up.

Probably.  There are a couple of online sites that explain it all.
Google is your friend; use it.

You don't get to use your car while it's being used to provide 110V AC.
You probably won't be able to cook, or even use your microwave
(depending on the microwave's power draw, of course).  You won't want to
use a hair dryer.  None of the 220V appliances in your home can be
powered.  Probably the limit is a few lights and the refrigerator.

You say the 12v will run down, others say it wont and the traction
battery keep it up, logicaly it is kept charged by the traction
battery as others use the inverter on it.
