Abstract
Disclosed are methods and systems for measuring and managing swelling of rechargeable batteries in situ. Some implementations involve using capacity fade or state of health of rechargeable batteries to estimate swelling of the rechargeable batteries. Some implementations provide methods and systems for measuring battery swelling based on inductive or capacitive coupling between sensors and the battery. Some implementations provide means to manage or reduce swelling of rechargeable batteries by applying adaptive charging with consideration of battery swelling.
