2012 plugin battery upgrades?

idk of any other places. very few gen 3 plug ins have failed, so there wouldn't be much call.

idk about gen 4 prime modules, maybe you could get hold of one at a salvage yard or ebay to compare.
voltage and amps should be in the service manual or new car features. both available at techinfo.toyota.com

 

I think I am the only one with the knowledge you seek... I have the only other Gen 1 Plugin to my knowledge with the lithium cells from Nexcell...

I also own a 2017 Prime, and after examining its battery case, I can confirm that the cells are different. What you're aiming to do is simpler than it might seem. So far, the cells in the Nexcell battery are the only ones I've found with the exact terminal placement needed to use the original equipment (OE) battery harness. I've identified the exact cells Nexcell uses and am now searching for taller, higher-capacity versions. My goal is to achieve more than 13.6 kWh in the 2023 Prime by using these taller, higher-capacity batteries. I've already designed mock-ups for battery case top extenders, which will allow me to secure the battery top even with the taller cells. Additionally, I have the OE harness connectors (both male and female) to extend the harnesses to the ECU, ensuring it remains connected after the installation of the taller cells.

There's also a new vehicle with battery cells that I believe will be compatible with these cars. I've informed all the auto dismantlers I know to contact me as soon as they have or are about to acquire this vehicle. I want to know the condition of the vehicle and other components for experimentation. Theoretically, I should be able to achieve around 50 kWh of battery capacity, potentially boosting the EV range to 100 miles. I just need a laser 3D scanner to scan the Prime clutch sprague, so I can reverse-engineer it to fit the 2.0L motor I have installed in my plug-in, using the Gen 3 transaxle. This way, I can drive at 80 mph in EV mode like the Prime. After all, what’s the point of upgraded batteries without the capability to drive in EV mode at higher speeds?

Additionally, my goal of upgrading the charging system is closer than ever. I aim to charge this 50 kWh battery in less than an hour. Given that the Gen 4 Prime can charge an 8.8 kWh battery in just 16 minutes, this seems achievable.


Regarding the DIY approach, I know it's possible and I have the know-how to do it, but with the NexCell battery available, it's no longer necessary for me. I understand the process, but I doubt most Prius owners are as daring as I am. Additionally, I don't want to undermine Jack's work and risk losing him as a valuable resource for all my projects, including those planned for later this year that aren't Prius-related.

bud, you have to be kicked down by the entire forum, and other water holes online and not care about what they say because while they do all the talking you've been doing lots of work. this is how you won't find them disputing or contradicting me nor the build process this far because they have never done it. I barely got the obd2 PCB board pulling what I need to feed the electric motor controller. the whole chademo charging is the next battle which I hope is easier. its possible I can acquire this battery I think will work, was offered some mirai cells, just hadtnt looked into them yet so I had them held for the time being.

this is the thing, alllll the new phev's on the market, for the most part have inner changeable parts to an extent. The toyo/lexus parts, the battery and charging I've gotten a good handle on, its the use of say the new 500h drivetrain or even rear motor system in conjunction with it all that Im not timid about as I know I'm gonna wreck my head against a wall there for some time.,

 

is it possible to change batteries only?
i mean in the orig pack there are 288 Liion cells 96s3p. total voltage: 345V
Is it possible to use Lifepo4 cells instead?
108x3.2V(30Ah). I would build another battery box of course.
If there are some voltage metering in the orig pack, how it is wired?
This would be the cheapest option for a 11kWh battery in a Gen1 plugin Prius if it is feasible.
EV mode is working below 96km/h and it is enough in the city.

 

idk if the bms can handle it, you might be the first to try

 

this worked for me...

those cells aren't the right physical size...

 

sure, but you'd have to be brilliant because you'd be the first to try, other than the nexcell

 

its not rocket science and actually easier than folks make it out to be. the PHEV is a lot easier than the non PHEV.

 

it's close though. otherwise, more would have done it. priuschat is littered with threads from people who wanted to do it, but never did.

 

not that close... I think most threads arent on the PHEV tho. That the key here at least based on what I know now. My 2009 is the only non-PHEV I have experience with and I just threw Lithium in there and called it a day. Now, I am on to making my own battery harness for my PHEV to install battery cells whose terminals dont match that of the PHEV. I'm hoping this company says yes to my request of making the terminal wires based on the specs I send versus the other way and need to manually do the cutting to size process.
