Prius PHEV with Aftermarket Brake Rotors and Pads | Regen energy gained while braking rate increased

like the title states... after installing cross drilled and slotted rotors with ceramic pads, driving down hill on a steep road that I've driven for many decades... before the brakes, I could never generate more than .09 EV miles while braking. After the installation 1.4miles was obtainable and repeatable.

now that I know there is a data field from the obd2 port that has "energy generated while braking" I have been logging the 2017 Prime I have for months, this way, once the new brake parts are installed, using a data visualizer ill be able to show the average of the EV miles generated show a significant increase over the OEM parts....

and some say there is nothing better than OEM... ha, incorrect words those are!

this is just one of the many things I personally discovered before anyone else... more to come on other unicorns I've found!

prius upgraded brakes

 

Not yet, it's almost time to change them, the car is almost at 100k miles so right after that it'll be ready to swap new ones on.

I call it the secret Toyota Sauce, there is still much about these cars the majority doesn't understand in the sense of modifying and with the knowledge gained within the modification to the by-products of non-OEM changes. I mean... my 2013 Plugin has just as much if not more range than a 2014 Prime after upgrading the HV batteries, If my theories are right, ill also pickup the EV power through the 80mph range and fast charging to achieve a full charge in 16 minutes. the Japan-spec ones can charge that fast... my guy in Japan right now is working to get the parts that are different between the US spec and Japan spec Primes.

so to your point on the time it's taking.... is a moot point when yu are doing something no one else has or investigating the unknown!

my theory... the better gripping braking system, increases the rate due to the better brakes. the PHEV has a data point called "energies generated while braking"... either brake fade over time cuts out ev miles generated thus the new parts would show a dramatic increase... or... it shows no decrease in this rate of energy over time then a spike after brakes installed. im sure there are other options I haven't thought of but... issa why Im going down this path, seeing what I experienced made me want to put some meat on the bones to see how or why I was able to set cruise at 69 in Colorado going down a long steep grade highway for many miles and when I got to the bottom and the highway was flat, my HV battery was fully charged and I had 14 miles of EV range. I've never before the brakes even charged that battery half way before...

hey.... we will know once the data is analyzed one way or another! I guess to say are we that jadded by disappointments in society that why have no glimmer of hope for the option of good and prosperity to come from the unknown? You would think support, even if just mental was there for even attempting to back up statements made which would have a huge curve ball in what we know to believe about regen on a Prius PHEV....

 

well since regenerative braking is a way of taking kinetic energy from the car's momentum and converting this into electricity... by the PHEV capturing the kinetic energy from braking and converts it into the electrical power that charges the vehicle's high voltage battery... plus Im not sure how just yet but planning to find out!

Thats all I can say as well, I know this is happening as I've experienced it first hand, just need more data to confirm and show how it's happening.

 

you realize... the PHEV is for the most part a different vehicle than the non PHEV... I've realized, there are many voices of reason yet, they said you can't use more than 1000W inverter on a Prius and I use two over 2000W without issues.... they said lifting a Prius more than 1.5" was bad for the suspension and Im well past that marker without issues. All the talks about what would be needed to upgrade the HV cells in my PHEV were also all wrong. Wait until I show you all what I've learned from this motor swap then proceed to swap the Hybrid Max motor in... heck, DOGMAN would bet his life on the fact Weathertech Floor Liners are the best ever on the market and now I don't trust a thing he says.

sure, okay.. trying to use one PHEV module in my Gen 2, I did talk with someone who believes they can make me a compatible boost converter to boost the volts up to 207 but I'm not ready for that endeavor to go sideways and left it alone.

It's also possible, that regen has nothing to do with the ev miles gained from braking and that my thought of higher performance components being tighter or grippier than OE would play a role in why I've seen a significant increase in the ev miles my car generates. it's like, at this point with basically most commenting here owning a non PHEV, there is no way for someone to say one way or another what the car is or can do just based on internet sleuthing or being a Toyo Master Tech. There is still much secret Toyota sauce we just dont know...

 

Well... why would the car have this data?

also... "It's estimated that most hybrids capture up to 90 percent of energy normally lost through heat during braking and use it to recharge the battery through electrical motor resistance, thus helping to preserve and replenish range in an electric or plug-in hybrid vehicle."

 

That's the dilemma... the 2013 Pluginn where I noticed this and installed the after market parts.. nope... so now the 2017 Prime I'm logging now so that after the brake job is done ill take say a month's set of data before and after the installation with hopes it all makes sense.

 

Hence why I'm wondering why the significant jump in EV miles was generated! I've never disputed the logistics of regen, I've simply stated what I observed and the plans to put some meat on the bones about how and the why... knowing we don't know a lot about the secret sauce... I'm not gonna put it past Toyota that this jump is attributed to the parts somehow...when I get the chademo charging components from a Japan spec Prime, itll be interesting to see how it all works in my Plug-in.

I'm on the trail of something hot, what if I told you I had a fresh engine block analyzed to fix the maximum bore possible, and that it's been done. what if I said, just like upgrading my HV batteries, the system did its thing and recalculated things to boom! I didn't even need to mess with the BMS and i have the same and soon significantly way more EV range than even the new Gen 5 PRime.

Did you see this response?
