can we replicate BTH data gs450h/prius?... Unlocking the PHEV

[Bigpie]

Any of these captures from HTM from stationary to moving off in EV mode?

Stationary car in a P gear and the battery is charging. It's HTB, not HTM btw.

[Bigpie]

ah, if you're able, would you grab a HTM when going from stationary to driving forward a little?

>Start recording, run to the driver seat, start the car straight away with depressed brake, change gears from P to D, accelerate and brake, switch from D to P, push start button to turn car off, run to the laptop in trunk to turn off recording.

Awesome. Thank you very much

I'm suspecting that data speed is faster than 24mhz, given that bit time is 62/42 for 16/24ms/s sampling speed. Also the start pattern makes me think there could be glitches because it's the only place with both channels sending (almost) the same signal at the same time.

amazing work! really this is one step closer to simulating the hybrid battery computer and thus achieaving the goals.

I have continue pursuing the other direction keeping the battery ecu and lying to it or modifying its firmware.

this is my 20ah(can do 100a , 150a for 5 second) 70 cell lipofe4 battery. hooking it into the prius this morning and will test mpg and eletric only range, try and see how much SOC it will use of the 20a. i have enough space in the box for 84 cells . 5 vs 6 cells per voltage block, 18.5 vs 21.9v fully charged per voltage block. the computer firmware will have to be modified to use 6 cells, but 5> we are about to find out!

In all honesty it looks like madness. How are you going to get an alarming notification when one of your cells goes under/overvolted? Cant wait to see data log from dr.prius and hybrid assistant app.
Meanwhile here's another log by different kind of a crappy dongle captured by PulseView. 2 sessions differing by trigger up/down hence the missing first 1.6us high state part in "sesja 2" file. Starting sequence makes me thing again that logic 2 knockoff dongle is trash. This parts highlits glitching in logic 2 too.

edit: I started reading about modbus and want to cry and drop all of this to hell. This looks way over my head. How many hours of learning are we talking here?

[lastphaseofthis]

this is my first test, driving out, voltage block 11 looks to be .2 volts lower at times then the rest, so i will charge up the battery by holding the pedals and then see what the difference is at the cell level, by removing the battery and taking off the top and bottom and if one cell is found very off then it gets charged and we will repeat. for now

the test shows 105!
