BQ34Z100: BQ34Z100 — Request for SoC/SoH Algorithms, Memory & Address Maps, and Initialization Behavior

Part Number: BQ34Z100

Tool/software:

  • Could you please specify the SoC algorithm implemented in the BQ34Z100?

  • What is the exact formula utilized by the BQ34Z100 to compute the State of Charge (SoC)?

  • What is the exact formula utilized by the BQ34Z100 to compute the State of Health (SoH)?

  • Kindly provide the official documentation that includes the register memory map of the BQ34Z100.

  • Kindly provide the official documentation that includes the address map of the BQ34Z100.

  • Upon vehicle start-up, does the initial SoC value reported by the BQ34Z100 correspond to the last stored value, or is it recalculated as a fresh measurement? I would also like clarification on whether the same applies to the SoH value.

  • What is the typical refresh/update interval for the SoC value during the measurement process?
