Part Number: BQ20Z95
Hi all!
I am intersting in the process of Chemistry updating procedure. Basic information is described in appropriate docs and the question is about Ra-tables values.
As me understand from the docs, Ra-tables synchronously updated with new Chemistry array loaded to gauge eeprom. Normally chemistry data characterised for SINGLE cell, correct?
If pack configuration is other then 1P, say 2P, the value of actual cell's impedance would be less in comparison to 1P almost by factor of 2.
I understand these tables will be updated after some charge/discharge cycles to correct values, but what about the very first initial learning cycle?
1. Should Ra values be manually corrected for number of parallel cells?
2. Are they corrected automatically in bqEVSW while updating the chemistry?
3. If they not corrected, does it mean first learning cycle would contain big error in Qmax and FCC calculations?
