    Could you take a look at these and let me know your own opinion of the battery health?

    This is done on a cold car, started then driven around a couple of blocks and then parked.

    The brief instructions say generally the normal NiMh cell voltage should be 14000mV-1800mV
    What say you that dip to 13000?

    Why are there no values for Rb1 and Rb2 in my initial data file to put on this chart?

    What IS MG? Is this torque or temp?? I wasn't sure if these were the temp readings so put temp on the vertical axis. If this is torque, is this in percentage of available torque to a max value of 100% or something else?

    What is Tin and T1 and T2?
    Maybe these are temps, or are these torques? It makes sense that these may be temps since they continue to rise except for T_in which oddly drops?

    You were probably accelerating when the voltage dipped. Look at SOC, Amps and HV Battery volts at the time of the dip. You will probably find Amps were high and SOC and HV Battery volts were low. This will happen during acceleration and high amp draw.





    Contact Nitin at OpenElectrons.com and ask him to look at your file.




    Temps






    Tin is HV battery fan inlet temp and is the cabin temps pulled in to the rear vent. As cabin temp drops this will drop. T1, T2, and T3 are battery temp sensors mounted on the HV battery.

    Yep, seem to have most if it figured out. Thanks for the guidance though. Results and interpretations have been posted on what did you do to your prius today.
    Thanks again.
