Rainbow Prius Hybrid Powered by Lithium!

Say, do you have a link to that specific inverter or its spec sheet?

In a quick search, I found some of their low volt DC input inverters, but not one for a high volt DC input. Maybe I wasn't looking in the right places.

 

Wouldn't you want one that could run a small microwave, or toaster oven?
Or a refrigerator, or a small window a/c unit?

 

Presumably once you've used up that 'buffer' capacity in your battery, you are not planning a "continuous" draw of any more than the 1200-ish watts you can get from the car's DC/DC converter ... unless you also have another source dumping power in?

 

Like he said 3000 W continuous. If that's true then the 12v should handle Most situations.

My house is off grid and uses a 48 volt battery so at night I used the Prius high voltage to feed into my solar charge controller as if the Prius was a solar panel and it worked decently enough

 

You don't have "3000 W continuous" available to the car's 12 volt system. That comes from the DC/DC converter built into the bottom of the inverter assembly under the hood, and if jacktheripper is talking about a Gen 3 Prius, then that converter has the maximum output shown in the Gen 3 New Car Features manual:



At 14 volts output and 120 amps, that's around 1700 W tops—and you don't get all of that; the car uses some.

So if you are planning to draw "3000 W continuous" from your inverter, that'll go on for as long as your 12 V battery has the missing more-than-a-kilowatt to chip in for you.

 

Sheer morbid curiosity, if you took two of the OE modules and conducted the same short circuit test, how would they react?

 

That would be nice! With a roof top tent it would be great!

 

Who uses 3000 watts split-phase in a rooftop tent? Is it a Tardis?

 

a true lifepo4 bms in the pack will not allow the prius to charge the lifepo4 batteries in cold weather so permanent battery degradation is the sacrifice trade off driving in 32F or colder temperatures.

 

Love the idea, but with the current price of a genuine Toyota battery at $1950 or less, what is the advantage of paying MORE for mostly untested tech? We still have serious questions about the longevity of the cranky $1600 battery guy, but he delivers it to your door and includes taxes for LESS.

Lol didnt know that was to much? Id be running a water heater, electric stove, a electric shower, small AC or maybe space heater in the tent, small camping refrigerator. Is 3000 watt over kill? I would also use it to power home in an emergence as well.

 

I think I am failing to visualize this rooftop tent.

 

Yeah I like the Dr. Prius screenshots. However, Jack's screenshot shows 19 mOhms for each module, another user show's 12-14 mOhms per module and yet another tester's screenshot show's 9 mOhms for each module.

So which is it 19, 14, or 9 mOhms? Big difference in ohmic heat loss. I understand that maybe the Dr Prius app uses the battery ECU's numbers that take time to refresh but it's confusing to an EE major.

For a different topic @jacktheripper - if the battery helps increase regenerative braking this can increase passenger safety. Maybe something to post test results for.

 

Hi Jack!

Thank you for the offer. Thanks to your app we are going to get into a prius + which I belive runs on lithium-ion with the battery in the center armrest. I was able to find one with delta SOC at 2.5% with your app and did the whole battery of testing. So I pulled the trigger with confidence. Will be for sure getting my replacement pack from you when we done with this puppy.
I hope the lithium-ion battery in the new prius+ is easy to work on too.
