    This is the gen 2 area Bisco. I think all gen 2’s have NiMH battery’s. To the OP I think the computers are the main difficulty with making lithium batteries work. If you decide to attempt this please keep us informed. It sounds like an interesting project.

    Nope gen 2 is 2004-2009 I believe, might be a year off on the launch year.

    Not to be confused with the Gen 2 PHEV, which were all based on the Gen 3 Prius.

    Gen 2 PHEV (Prius Prime) is based on the Gen 4 Prius (2016+)

    The Gen 1 (2012 - 2015) was based on Gen 3 Prius refresh.

    Why do you think the computers would be the difficult part? Thank you.

    Do you know how many it would take?


    The 90 Kwh battery is made of 16 modules . Each module has 444 cells arranged as 74 cells in parallel and 6 of these 74 cell units in series. Each module has an output voltage of 4.2 * 6, or 25.2 volts. These 16 modules are then connected in series to provide 16 * 25.2 , or 403.2 volts. The lower capacity batteries only have 14 modules in series, so their output is 14 * 25.2, or 352.8 volts.

    how many would it take to what?

    physical size is your issue. how much of the hatch do you want to fill?

    you would have to be competent enough to go into toyota's proprietary battery management software and make adjustments for battery chemistry and size

    are you looking to make a plug in, or just replace your pack with tesla cells?

    Retrofitting a vehicle with Tesla batteries can be done, but is not easy and comes with risks like thermal runaway. Check Rich Rebuilds:

    The computer charging software circuits and wiring were designed for different battery size and chemistry. The computers were not designed to be field modifiable.

    My question is why do you think it would be easy??

    Replace with Tesla cells to build new replacement hv batteries.

    Gotcha. There are a few issues. Tesla cells are vastly different than Prius. They have liquid thermal control and appropriate battery software management.
    Anything can be done, but the necessary dkills and knowledge are rare.
    You won’t find any help here, only one or two have passed this way with that kind of ability.
