    This test was started on 11/16/23

    On this day I went to Nexcell and Jack upgraded my lithium pack to the v2.5 and on purposed placed an overcharged module on #14 and this install did not include the soother at this time.

    Below image is the first start with this pack and #14 module test without soother.

    Notice how #14 is higher voltage and internal resistance than the rest.

    No codes were thrown at all and the soother was not installed.

    Please be patient for further information about this test as I am going through images and information to post them.

    On this day 11/17/23 this was a idle test with ICE on as you can see it is charging.

    Notice #14 is yellow with just an idle charge happening.

    Still no soother installed and no codes.

    On 11/24/23 the soother was installed.

    Things were looking much better after this was installed. 20240316_134806.jpeg

    This is on 11/25/23

    Please pay attention to this image with a discharge of 1.47 amp and other data compared to the first image in post #1 of first use with a discharge of 1.65 amp and similar data.

    Notice here #14 has lower voltage now but still has a the highest internal risistance.

    No code thrown with the soother in place. 20240316_135823.jpeg

    On 12/17/23

    My Prius was not going anywhere.

    P0A80 code was thrown (12/16/23) with soother in place.

    (More images of 12/16/23 to come)

    The following images are all on the same day 12/17/23

    First two images are 20 minutes apart.

    Third image is 1 hour and 25 minutes later. 20240316_142424.jpeg 20240316_143042.jpeg 20240316_143436.jpeg

    This image is on 12/19/23

    #14 is swollen and code was thrown with soother in place.

    Jack installed a bad module on #14 in my pack on purpose to test for safety and a code was thrown while the soother was in place.

    12/16/23 the day the code was thrown.

    Pay attention to the time in the pictures.

    All of these images are on the same day.

    I attempted to drain the HV battery but code kept coming back and going into safety mode. 20240316_164550.jpeg 20240316_164600.jpeg 20240316_164800.jpeg 20240316_164806.jpeg 20240316_164817.jpeg 20240316_164831.jpeg 20240316_164837.jpeg 20240316_164842.jpeg 20240316_164849.jpeg

    I haven't commented because this is the first time I've seen it as this is posted in a Gen 3 forum and I don't lurk there.

    I'm not sure what you expect people to say. As for me, I'm not sure what it proves. The "experiment" does not seem to be very well structured or scientific. Details of each step's objectives, the method used, and the results in some sort of summary would be useful. We could then draw our conclusions from that.

    It still does not answer what the design of the "soother" is and what is supposed to do which would be of much more interest to me and others.

    Why the debbie downer energy? Cant we all just get along? Gezz. Clearly we are all wanting the same goal, I know personally I dont know everything and the only way use cases can be flushed out is with the help of the common collective.

    I mean, whose to say one chooses to protect themselves from higher powers that be? You can't use them protecting themselves against them, there are forces out there with strong fire power like bulldog lawyers. They might feel some type of way about whats being done to the product they manufacture. Rich rebuilds has a nice state to shield. Sometimes I dont think people really think about whats being done here...yet quick to judge and lead with fire and brimstone. smdh what have yall been through IRL? I'm here to talk if you need to.

    Sorry you perceived it like that, it certainly wasn't written that way. Maybe taking the crystal/new age/touchy-feely hat off and donning a good sturdy science one would be a good first step.

    We're just interested in the facts.

    I would like to see video evidence of the Signal Soother doing it's thing realtime as I asked in my original comment on the failure thread. Comparing multimeter readings directly to Dr. Prius readings while the modules and bad modules are under charge or discharge with the soother installed would give better realtime results for what's happening...

    Unless the Signal Soother is extremely well made... installing a device that alters voltage readings from the pack is a horribly unsafe idea and I doubt it's been tested well to know that in all circumstances it doesn't reduce or circumvent safety mechanisms.

    Also, Internal Resistance readings from Dr. Prius are not instantaneously accurate when being transmitted via OBDII dongle. IR is not transmitted externally until the Hybrid Battery reaches above 70°F in temp... and then even after that, it seems to use a sliding average rather than an instantaneous reading based upon charge going in and out.

    IR readings taken when the Hybrid Battery is below 70°F are not accurate because they are not being transmitted via OBDII dongle... but are still being read and taken into account in the background by other software and hardware mechanisms in the car. When below 70°F... the Prius transmits the last measured Internal Resistance reading via OBDII continously until the Hybrid Battery reaches a temp of above 70°F... at which point Internal resistance readings will start updating externally again. So anything below 70°F temps... the transmitted IR measurements via Dr. Prius will be frozen on the last measurement taken when above 70°F.

    I think any OBD2 dongle readings from a low cost device should be thrown out and not used. The only OBD2 device I've found that can send real time signals fast.. very fast is the device I recommend to all. If you have Android you can get a Bluetooth app to view real-time data from the port. and yes, its fast but I believe I might just have made a faster device on a PCB board. Think, Bluetooth, wifi, sd card and a few other nice options like techstream over Bluetooth might just be possible with this new board.

    I hadn't commented because, like dolj, I didn't see much to comment on.

    One of these three descriptions of the Signal Soother is correct:


    A. it completely suppresses the real battery readings and looks OK to the ECU no matter what.

    B. it passes the real battery readings unchanged, just as if it were not there at all.

    C. it does something that isn't A and also isn't B.

    The experiment in this thread, if replicable, appears to rule out A, leaving B and C on the table.

    Could B be right? I haven't seen an experiment rule it out, but B would mean Jack put a lot of effort and money into a "signal soother" that doesn't do anything to the signals. We might rule out B on common-sense grounds.

    That leaves us at C ... which is probably what most of us already expected.

    C, of course, covers a lot of ground. "Something that isn't A and also isn't B" could be something pretty smart, or something not very smart, or something very not smart. So there are still real questions that could be answered by learning what the Signal Soother really does.

    There are already at least two PriusChat members who have offered to examine a Signal Soother and report on that. We'll know a lot more when that happens.

    I'm having a hard time understanding what DrPrius is showing. Second guessing what's going on with a bad module #14 looks like it's making #13 hot too, comparatively. What I really was looking at was SOC. Looks to me like 230 volts is normally around 65% and 220 volts is normally around 25%. The other readings especially between 215 and 249 volts are confusing. And I can't figure out what is happening with that.
    The early morning shot is another one that caught my eye. It looked to me like you drained that pack pretty good before taking that screenshot.

    Nope. The one I own is fine. Internal resistance updates via a sliding average and only when the Hybrid Battery Temp is between 70-116°F.

    The charts in the video below were made with same OBDII Bluetooth dongle I used to measure internal resistance readings in Dr. Prius. You can see the parameters update multiple times a second:

    Well it alters Voltage readings in some way shape or form... I assume it has zero effect on actual module balancing because it "sooth signals". The fact it alters raw voltage readings on it's face is just a bad idea unless it's extremely well made.
