Log Parsing tool available

Thank you Tom for a prompt reply the log file has been set. It looks like I may have a low brick as #49 has been low for the last 600+ readings.

Has anyone asked Tesla whether they consider this an indication of a potential issue? They seem to have other methods of determining issues with the pack; I would think that they would use this method also if it is of real value.

Have you tried some deep cycles and range charges to see if it changes?

A new version of my log parser is now available with support for reading an approximation (± 0.03) of the car's Calculated Amp-hour Capacity (CAC) and a few other minor updates.

CAC is a value that some Tesla service techs have been telling owners is the best measure of the battery pack's capacity. The CAC for a nominal new battery is 160 Ah. It seems to correlate very well with ideal range in both standard and range mode and makes for a simple, unambiguous way to compare different battery packs.

If you'd like to compare your car to others, you can see a bunch of cars with their CAC values on the Plug In America Roadster Survey results page. If you haven't already, please consider adding your vehicle info and CAC to the survey.

Yes I have asked two different rangers and I am told the car passes the "bleed test" with no issues. To be fair from what I can tell while the one brick is low it is not much different than the others. While my battery pack is on the low side "176 ideal miles" it does not appear to be abnormally low.
