    Ming, I'm not sure whether Chemdat files are up to date or not. If those files are not up to date, where can I get the latest files. If those files are up to date, what should I do? Thanks & best regards Benn

    Hi We are implementing your bq27501 battery monitor. We are having problems with the RID function... The monitor does not seem to react to the change in RID resistor. Could you please explain when this test is done and how the test is performed. ie.... Is it done only apon battery insertion or a reset...

    Hello, we want to use BQ78PL116 for our new product, but we have difficulties in finding the correct cell chemnistry ID for our cells. We made a discharge cycle on one cell with a C/20 load and the described waiting periods. The log file is attached (Temperature was 22°C). Can TI select the correct...

    Hello everybody, We are going to work with a LiFePO4,PSI 12000mAh, but there is no chemistry file that matches the cell entirely. The most closest Chemistry ID seems 0410 which includes "PSI 10000mAh" without any test procedure. I found out that we can use bqEASY to select right chemistry...

    Is there a way to associate an unlisted Li Ion cell to the best match known chem id using the Chem.log file produced by the TI EVSW with the EV2300 during the automated chem learning cycle? If so, how? If not, can this association be done manually? Logged data and graph are attached, I hope. Thanks in...

    Tom, Thank you for your answer. + I was able to resolve the drift problem to some degree. When cycling the pack with 8h rest time the RSOC still drifts a little, but adjusts itself in some cycles after the OCV Idle Qualifier has elapsed. The RSOC still drifts when cycling with a short rest-time...

    When you test a battery to create a new chemID, what kind of tests do you do? You require some batteries. Is the log data from battery maker insufficient?

    Hello Tom, I did find out, that my "Transition to Idle Current" - Value was wrong and the bq78pl114 never went into the idle-state. After changing the value, the bq78pl114 did go into idle-state and now I'm experiencing the same problems described in http://e2e.ti.com/support/power_management...

  • Forum Post: Incorrect RSOC after discharge simulation on BQ78PL114 S12

    Nigel Wade
    In our application, when the battery starts a discharge after CC has been set, we always see a step drop in remaining capacity on the BQ78PL114 S12 a few seconds into the discharge. This leads to a corresponding drop in RSOC and is due to the discharge simulation performed by the BQ, specifically from...
