Hi TI engineer:
I have a questions about The method of Impedance Track for updating Qmax of chip BQ40Z50
Does the Impedance Track update Qmax based on gold learn instead of based on storage time ?
For example, if a battery has been unused for two years, will the Qmax be updated only based on the storage time?
Looking forward to your reply! thank you!
Hello Zehu,
Qmax doesn't update based on storage time, reference the image below for the conditions that need to be meant for Qmax update. In order for qmax to update a discharge/charge event needs to take place. Please reference this e2e that has the same concept to your question as well.
