Abstract
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.
