Production flow bq40z50

Other Parts Discussed in Thread: BQ40Z50, BQ20Z45, BQEVSW

Dear all,

I have acquired a bq40z50 EVM module and installed the Battery Management Studio Version 1.3.9 and I am just about to start evaluating this  new device for a new application. I have also downloaded the TRM manual (SLUUA43) to start programming all the DF parameters.


Just so I am not missing anything - the process of going through the learning cycles is it the the same for the bq40z50 as for the bq20z75/bq20z45 using the bqEasy - and is the battery pack Production flow for the bq40z50 as discribed in SLUA391?


Best regards

Kjell

    Kjell,

    The learning cycle process should be the same, although the commands may vary slightly. The bq40z50 allow you more flexibility with turning features on and off. e.g. IT, FETs, faults, etc.

    Tom, Thank you for your support. A last question: When working with the bq40z50 the Battery Management Studio should be used instead of bqEasy, or does a version of bqEasy excist that is compatible with bq40z50. bq40z50 seems to be an interesting component with a lot of features and going through the learning cycles I just follow the same practise as for the bq20z75/bq20z45 where I have my experiense. Best regards Kjell

    Kjell,

    The Battery Management Studio is our new evaluation tool and will replace bqEVSW on all of our new devices. You can follow the same procedures that you have used on the older devices for the optimization cycle.

    Tom,

    Thanks so much for your support. I will follow your advice and start programming the DF parameters and perform the learning cycles for bq40z50 using the Battery Management Studio. Interesting to compare the performance of the bq40z50 with the bq20z75/bq20z45 in a demanding application using LiFePO4 type of cells and high current pulse loading. If I discover some interesting topics I will keep the Forum informed.

    Best regards

    Kjell
