Thanks Nick !

 

I’m the beta tester. This weekend was able to achieve 24 miles freeway speed between 55-65 mpg, of course they’re various factors involved, but from my point of view it’s excellent!

 

a link to my first entry in the Top 20 game for the PiP on page 29 of 35 pages. Most of the post to the thread were in the summer of 2013. There were only 3 chargers, at that time ( summer 2014 ) that I could reach in EV and than only 2 when the university banned public use of their chargers. Chargers 2 and 3 where about 12 and 13 miles away, while charger 1 is 3 miles away.

Personally, I think from what I just seen Jack do on video, his new nexpower pack for the PiP is a much simpler way forward that trying to add a second OEM traction pack to the PiP.

The only question I'd ask is, what are the dimensions of 1 of the 4 banks of modules.
I'd like to measure bank 1 of the 19 cells/bank in the Prime to compare.
When I actually do get to that one bank, I'll be sure to check if the cells are liquid electrolyte.


Thanks for the videos Jack and the PrPrius app tooo....

 

Hi @vvillovv , you are welcome, we will work on Prime battery replacement later this year.
regular plug-in dimension 17.5L * 6 1/4W * 4 1/2H

 

I meant mph ***

 

Hello, maybe this is a very stupid question because it may be a different car but the other day I saw a WeberAuto video about the dissasembly of a plug-in prius big battery and it had 5 long modules, the one in the video only has 4, it is because it's an older model? so this nexcell batteries wont work on the newer batteries? thanks

correct, this is the 2012-2015 plug in with 4.4 kwh, the 2016-2022 plug in (called prius prime here) is double that size

 

Have a 2017 Prius Prime Advanced w/43k mi. that suffered rodent damage to the battery wiring harness. All cells in the battery are fine. However, Toyota will not replace the harness, only battery w/harness. It has taken months to get the new batt., but it is supposed to come in this week. Looking for ideas about how to insure the old, perfectly good battery ends up in someone else's car rather than being trashed by Toyota's recycling sub-contractor. Advice is welcomed!

 

They aren't scamming me so much as the insurance company, which confirms the Toyota protocols are real. Travelers will only pay for a new batt.

I will be in for the $500 deductible.

 

According to the other thread, this is a decision above the dealer with Toyota and the insurance company.

They probably have concerns of unseen damage to the battery.

 

Insurance companies won’t argue with mfgs rec’s like an individual might. it’s too much of a safety risk

 

Absolutely. As the damage has already been documented, anything other than the recommended protocol may well result in the vehicle becoming uninsurable (or refusal to honor any future claims). Better to eat the deductible and think of it as an upgrade from a tired 5 year old battery to a fresh transplant for a mere $500.

 

what is the total kWh this new battery?

 

huh? you know... I still like you, just... I didn't know I had to share my findings with the world. Separately... I only mentioned being able to modify the main ECU, but... when I am ready don't worry sweet cheeks, you'll know and you'll know only what I want to share. the world is bigger than your assessment and there is a lot more going on behind the scenes.

The performance gains ill get is from the rear electric motor I'm adding and the additional power from a larger capacity battery. I'm just trying to get over the obtain battery with more than 50kWh and obtain CHadMo components from the Japan spec PHEV so that it doesn't take 7 hours to fully charge.

 

good sir, I wasn't aware I had to share just because I was asked. Others have shared similar sentiments, and I did not get the memo that says I have to divulge information when asked. Sure, I ask for info, like the total kWh for the battery. Doesnt mean it'll get answered, and if not, I am okay with that.

I tell yah, the assumptions people have, truly make me laugh out loud. The reason, most appear to not think outside the box... why didn't you think that I wanted to prove and test my findings before divulging information? How come I didn't want to provide inaccurate information so I'm withholding information? Particuarly for the fact that every post I've done, thinking outside the box, and others like the coil thread right now, is met with hostility and people refer to what they don't understand as "snake oil".

I mean hell, I drove a V with the track quantum and I felt the gains yet a whole group of members still feel its snake oil.

I've realized though, I am different from possibly 99% of the owners. I dont know all, I am also willing to test and make mistakes in this exploration stage I am in. Pushing the Prius to the limit to see the weak points and be able to make anything I want puts me where sure... I might be hesitant to share for collab as anytime I post a theory or idea it hasn't been met with open arms. Heck... all of the nonsense and public shaming of me because I've been busy attempting to take my car to the ultimate Tesla Eating Prius status, while developing new parts and trying to communicate with customers plus defending my name because people feel they shouldn't have to wait to receive a product no one else manufactures? What's funnier, everyone else can share their opinions, but when I do, I get called out? Someone just linked to another thread trying to "showcase" my opinions and pursued others to read how I am or the philosophy they feel I have that doesn't agree with theirs. Clearly, an attempt to in a nice way tell folks dont purchase from me. ha! the nerve!

Lastly, the Gen 3 Prius has been around for what... five years! Now that Gen 5 is out, in the time I've been around the below parts are now available, there hasn't been any work together to benefit the community that I've seen prior to even having one of these items made! When people do attempt to try something new they get bashed on. or... when I do share, and state my findings, like.... non-OEM cross-drilled and slotted rotors with ceramic brake pads during braking on a PHEV, the EV mile range significantly increases faster. I didn't have a capable obd2 device nor was I logging (well I was just after realizing the dongle I used was cheap and not quality enough to communicate fast enough, plus I corrupted the database file id been saving for over a year) properly to be able to show the value in the ecu called battery EV generated while braking (dont quote me here on exact wording but it is data available on the PHEV). I need to attempt to recover the data but have been recording data on the Prime, when it's time for brakes, similar parts as my PHEV will be installed and I can't wait to see the data. People will still say it's invalid for whatever reason just like they say "regen doesn't work that way" but they drive a non-PHEV and make comments on the unknown as if it were facts... so, dont try and force me or shame me because I didn't share with you, my experience is it best to hold my hand until I am 100% sure with significant evidence in support of my findings, else with no experience in a PHEV, the ones around here will try and state their opinions based on what they read online with no hands on experience... and say I am wrong.
