    Hi, i´ve got an issue with reading cellvoltage. In bqWizard cells window are the correct values shown, but with the SBD Read/Write Utility "wrong" values for same cell are shown, see picture. Is there any conversion factor needed? (Please visit the site to view this file) Is there...

  • Forum Post: bq78pl114 with bq76pl102 industrial calibration without bqwizard

    Andreas S
    Hellow, the data sheet of the bq78pl114 refers always to calibrated devices if terms related to accuracy. So calibration is demanded. How is it possible to calibrate the bq78pl114 with bq76pl102 in an industrial manner without the need of artisan bqwizard usage? Can we for example produce the calibration...

    Dear Jim, Thank you for your fast answer. i just took a new pcb into operation. I pushed the 76PL102 calibration into the 78PL114 (not 78PL114) using the "calibration transfer bit" and a calibration/relearn sequence. The result was obvious, the cell 5 voltage is nearly exact. Reading...

    ! ! CORRECTION ! ! Statement about impedance learning is updated. If NDI calculations occur, then the impedance values of the cells will be updated. 2) Aux files are dependent on cells and pack construction. Impedance values are not learned over time from some nominal value to whatever your specific...

  • Forum Post: Re: bq78pl114 access level

    Jim M15252
    Short answer is I'm not sure how you got to access level 0. Once in bq78PL114S12 there really isn't a way to get out of Access level 0. Access level 2 is the only one supported right now for bq78PL114S12. The bqWizard interface for bq78PL114 (FW4452) allows editing of access levels and setting...

    Unused sensors are left open circuit - no problems. Use the bqWizard 3.0.16 to upgrade your firmware to bq78PL114S12 or use the new bq78PL116. Then use the Pack Configuration Utility in the bqWizard to create a .tmap file which will specify how your temperature sensors are arranged.

    Look at the description of this safety feature in the SLUU330b Technical Reference Manual. This could be indicating a problem with your pack, like a broken weld strap. Relearn/Initialize should clear safety counters.

    You cannot use a FW5000 .tmap with FW4452. I strongly recommend moving to bq78PL114S12. If you are using the EVM for development there is a simple upgrade procedure. All that is needed in terms of hardware is a soldering iron and some solder.
