Welcome to the Texas Instruments Introduction to Battery Management product training module, part two. This is the second course in a 5-part series that covers some of the key aspects of battery technology. This session will cover the basic concepts of battery monitoring, also known as “gas gauging” or “fuel gauging” for battery applications. Accurate battery monitoring is especially important for Lithium-Ion battery applications, not only to provide the user with an estimate of remaining battery capacity, but also to ensure safe, reliable operation and to maximize the lifetime of the battery pack.
