Aux file generation current

Other Parts Discussed in Thread: BQ78PL116

We are trying to generate a new .aux file for a battery using the bq78pl116.

The cells are nominally 50Ah, and have been tested and shown to have 59Ah capacity. The instructions for generating the .aux file as in SLUA505B suggest data collection should be performed at a discharge rate of C/2 and a charge at the same rate. For us this is nearly 30A, which we cannot achieve.

Are there impacts in using a slower rate of charge/discharge?

Our current configuration allows us to charge and discharge at around 6-7A.

Do we need to perform the looped instructions 6-9 for longer than 1 minute to account for the lower-than-advised discharge rate?

  • Follow up:
    our battery uses 4 of our 50Ah cells.
    We've had a closer look and it appears our nominally 50Ah cells are themselves internally a collection of (maybe 20) cylindrical cells of chemistry 401. Do we represent the pack as 4s20p in the tmap file etc.?
    Will this impact the aux file generation?
    Does this mean to discharge/charge at C/2 means we use something more like 1.5A?
