Plug in battery into gen 3

Without extensive modification, you can't add a second battery to a stock Prius. You -can- buy a "plug-in" kit, but it uses a different battery, not a stock Prius battery.

 

agree^^^ it will not recognize it, it's never been done, and yes, you would have to make extensive software changes. even the add on kits have new controllers. heck, i don't even think you could fit it in.

 

EBay.

 

we've never heard of one going bad, so no purchase price yet. you could look and see if anyone else is trying to sell one. iirc, someone in nz, aus or u/k spotted one asking $1,500., but i'm not positive.

 

please let us know how you make out. any idea how many miles on it?

 

wow, you got a good one!

 

Right now these batteries are probably going to be a hard sell. Statistically, there aren't a huge number of plug-ins out there. The battery being unique to the plug-in puts a real damper on it's saleability. The Nmh batteries typically go for between $800-$1500 on eBay. Your Lipo battery is zero on eBay. OMT, if that lithium battery goes flat it takes special equipment to revive it. If it does go flat, you'll have a 75lb piece of junk.

 

Wait! Is this the 100 lb+ Prius Plugin battery or just a normal Prius battery? If a normal one it's worth about $2500 new, maybe half that used. The Prius Plugin battery is worth a lot more. It's very large and very heavy. The standard Prius traction battery is maybe 70 lbs.

 

You're absolutely correct. My mistake. The Toyota Prius Lithium Ion weighs in at 330 lbs.. That is forklift removal time.

 

I just checked Car-part.com (Salvage yard search engine) and the Plug in Prius batteries, Lithium are going for $1105

 

You're thinking of combining a Lithium ion battery pack with a Nickel Metal Hydride one, or replacing the NiMH pack with a Li-ion one? You do realize there would have to be immense software changes? It's not like an AA-battery with a + and a - which hooks up to the car. There are extensive electronic circuits wired into all of this and it's all configured to a specific battery chemistry and capacity. You can't just interchange them willy nilly.

 

i i have aquired a prius plug in battery from a 2013 prius! Am windering if i can fit this to my gen 3 2010 model!

Unlikely. How experienced are you at working with electrical control circuits??


Can i use both batteries together?

Difficult.


Wil yhe ecu reconise the other battery !

No.


Wil i have to make any other changes?

The entire car is tightly integrated to itself. If you make a random change to the battery the car will probably go nuts. It will know something is wrong, but not how to respond.

 

The car will most likely respond "dumb". Meaning it won't go anywhere. Probably not start and get to READY either.
I expect it's programmed with a bunch of self-tests that it goes through before READY is displayed. If any of those fail, it will not start. If it's a "common" problem leading to the test's failure, it will throw that code. All other instances; Nothing.
