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.

Circuitry and techniques for determining swelling of a battery/cell and adaptive charging circuitry and techniques based thereon

A wireless charging system for charging a battery may include wireless charging circuitry based on inductive coupling, where the wireless charging circuitry includes: control circuitry for adaptively charging or charging a battery/cell; and an output of the charging circuitry configured to apply an adapted, unregulated current and/or voltage to the battery. In certain embodiments, the adaptation of the unregulated current and/or voltage is based on the charging and/or operating conditions of the battery.
