His argument, Prius will only generate electricity for as long as it moves.

He is right but for the wrong reason.

The Prius will indeed TRY to keep the 12 V battery charged as long as it is ON, that is in the READY mode and in Park and not Neutral.

HOWEVER......to produce 1KW of power, that would require about 85 AMPS out of the 12 V battery and it's charging converter. Neither the battery or the charging converter are designed with that kind of capacity.

It would work......for about 3 minutes.

I seriously doubt that the Volt has the capacity either.

 

Dear Easy Rider,
Thank you for your quick answer.
The 1000 W inverter is a bit overkill, but we should have extra capacity.
Regular refrigerator is rated at 6.5A, i.e. 700W.
This is only for few seconds, until it reaches the pressure differential.
After that the power consumption drops to 200-300 W.
Correct me, I may be wrong.

Drawing 85 A from a car battery is not a problem, especially a few seconds.
Cranking average car with average battery, current goes to 200-300 A.
For few seconds only, true.
The biggest problem, I think, is how much current can the car produce to refill the 12-V battery.

That's why, I insist that only LED lights, laptop and cell phone chargers should be plugged in. The big consumers are AC, water heater, dryer, etc. However, during emergency, we can go filthy stinky and unshaven for few days. Hot water is always available on the gas grill.
Most important, to save the food from spoiling.

You are overlooking the fact that the Prius does NOT use the 12 V battery and a conventional starter to actually start the engine. Because of that, the battery is MUCH smaller than in a conventional car; about half the capacity of some cars.

And because there is no huge current spike required.....ever.....there is a smaller battery AND a charging system with a much lower capacity. Your proposal is NOT practical. But if you do try it out please let us know how it works.....or doesn't.

And as far as your other proposal........there are dangers when tinkering with the HV system, both to YOU and to the car.

I think that screwing around with a ~$25,000 car instead of just buying a ~$3000 generator is just plain stupid.
And......all that just to save a hundred dollars in potentially lost food ?? Really ??

 

PS: I did my home work. This is an old idea.
There are places over the internet about this.
12-V battery is not involved.
Plug the big battery to a big inverter. 2-3 or 5 kW, depending how much you plan to draw.
It will save money compared to standard generators, because the Prius engine is much more efficient than the gas generator honda or briggs+stratton. And also, because you only generate what you need. And it is silent!

 

Sounds good, I never thought about this!

 

Never heard of that, but this sounds pretty interesting. But ok to the honest, I am not sure that the Prius battery is big enough to serve as a generator, or the least to do that for a long time. That's why I love classic generators, I recently bought from the internet a new 5000W generator, and I am happy. In case someone is interested you can visit this page. So I have the opinion that the classic generators are the best. So try to prove me wrong, if you will can. Good luck my Prius lovers.
