    I checked the bq20z655-R1 product folder and it looks like the wrong bqEVSW setup program is referenced. I will get this fixed, but I can provide a link to download it earlier if you can provide an email address.

    Hi  

    Whan I  select chemistry . EVSW program give this " cannot find device encr files"

    I have  EVSW bq20z655-R1 V0.03

    Would you help me to solve this problem ?

    Is there full Manual of EVSW to design project and examples?

    Seems to me TI produces bq20z655-R1 but cannot/chooses not to support them, everything software related tied to this chip has bugs, OR simply does not work.

    Chemistry updater does not work with bq20z655-R1
    TesterDFReader does not work with bq20z655-R1

    Without these tools, I do not know how to get the single or multi station tester software to work, since you cannot generate a .rom file.

    You may want to pick an IC that TI does support.

    Update:  The bqDFReader seems to be working, with new “targets” file from Thomas.

    bqTester working with new “targets” file, but still will not program .rom file without errors.

    I am currently seeing another problem, that may be related to the chemistry selection:

    The packs' full charge capacity is decreasing for an unknown reason when discharging/cycling battery packs at a lower than maximum discharged capacity (85% was used in latest tests). This causes the packs to report that they have ASOC of 0% when the cells have 10% or larger charge capacity in them. I tested 4 packs which reported a Full Charge Capacity of about 82% of the rated capacity after 7 cycles.

    Please provide the log file showing the problem and a senc file from the pack and I will cehck them. I will have to retest the chemistry updating problem.

    Tom,
    I sent you a SENC file, and will send you a log file tomorrow.

    WaterSkier,
    Wondering if this was resolved? Did you send the files, or find a solution?
