  • Patent number: 10574079
    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.

  • Patent number: 9912181
    Abstract: A system to recharge a battery including a first current-voltage source to generate a first signal, a second current-voltage source to generate a second signal, a first inductor-capacitor circuit to generate the first DC current-voltage signal using the first signal, a second inductor-capacitor circuit to generate the second DC current-voltage signal using the second signal, wherein the first and second inductor-capacitor circuits are spaced apart by a predetermined distance. The system also includes a temperature sensor adapted to generate temperature data during the charging operation, and control circuitry configured to: (i) determine whether the first temperature data is out-of-specification, and (ii) generate one or more control signals to adjust the first and second DC current-voltage signals, in response to the first temperature data being out-of-specification.

  • Patent number: 9035623
    Abstract: Circuitry and techniques to measure, at the battery's terminals, characteristic(s) of the charging signal applied to the battery/cell during the recharging operation and, in response to feedback data which indicates the charging signal is out-of-specification, control or instruct the charging circuitry to adjust characteristic(s) of the recharging signal (e.g., the amplitude of the voltage of and/or current applied to or removed from the battery during the charging operation). For example, a rechargeable battery pack comprising a battery, and controllable switch(es), a current meter and voltmeter, all of which are fixed to the battery. Control circuitry generates control signal(s) to adjust a current and/or voltage of the charging signal using the feedback data from the current meter and/or voltmeter, respectively.

  • Patent number: 5420493
    Abstract: An integrated AC adapter and battery charger is disclosed. The apparatus comprises an AC adapter unit for converting AC power to a DC power and a battery charging apparatus coupled to the AC adapter unit for charging a battery pack. The battery charging apparatus further comprises a microcontroller for sensing the condition of the battery pack or tacks being charged, a memory for storing the proper charging profile for a number of different types of battery packs, and a charging current generator capable of generating a varying charging current based on the microcontroller's determination of the battery's condition and the charging profile stored in the memory.
