This on-demand technical training reviews multiple algorithms used in TI battery gauge products for specialized industrial applications. This includes primary cell gauging (LiMnO2 and LiSOCl4 chemistries) using the bq35100, and algorithms for use in rarely discharged (backup) systems, including End-of-Service (EOS) Determination and WHr Charge Termination, using bq34110 and bq34210-Q1.
