This user's guide guides through the following tasks:
These tasks guide users of the BQ27Z558EVM through the process required to prepare for production with the BQ27Z558 by creating a Golden Pack. A Golden Pack is a single gauge and battery that has had optimization and configuration processes performed during the development stage. The resulting values are extracted from the Golden Pack gauge into the Golden File or Golden Image. The Golden File is a flash image programmed into every gauge used in mass production as there is minimal pack-to-pack variation during a well-controlled manufacturing process. The Impedance Track™ algorithm enables the gauge to continue to learn once a pack is deployed to account for manufacturing differences, field conditions, and battery degradation over the lifetime.
