    A couple of things about DrPrius. One screenshot can be really misleading and a couple of screenshots from different drive sessions can also be confusing.

    Taking a few screenshots from one drive session where you start with a screenshot like the one in your previous post above, than get another DrPrius sceenshot when the car codes.

    A screenshot between the beginning and the code setting time would also help.

    There appears to be at least one communication issue, as can be seen in several of your Dr Prius screenshots that I've skimmed so far in this thread. Some of the screenshots show battery temps and some don't.
    I'm not sure yet, might not ever know what's happening in these two red graphed DrPrius shots back in March.

    I got the funny feeling since you mentioned you had lots more screenshots, that those two red graphed screenshots were taken from different drive sessions.

    Post #55 from March 2011 does not mention SOC. SOC is not what I thought. Why would I want a "state of charge of 0%"? Is it the balance or difference of charge between the 14 module pairs? I can see that it is best to have all modules to be charged and discharged the same. But if they all have a max capacity of, say, 1000mah, that would be very bad.

    Oops! I left out the word, "Delta" after the "SOC". So, does "SOC delta" indicate the difference in the charge level of each module pair? I don't see how it can be 0%. Do I need the Dr Prius app to measure it?
