  • Patent number: 10045764
    Abstract: An external medical device generates a drive signal inductively coupled to an implantable coil from an external coil. A regulator module coupled to the implantable coil generates an output signal in response to the inductively coupled signal and a feedback signal correlated to an amplitude of the inductively coupled signal. A signal generator receives the output signal for generating a therapeutic electrical stimulation signal.

    Abstract: A method of charging a battery includes applying a charging voltage to a lithium-ion battery for a period of time after the battery is fully charged. The battery includes a positive electrode having a positive active material, a negative electrode having a negative active material, and an electrolyte. The negative active material includes a lithium titanate material and has a capacity that is less than that of the positive electrode. The charging voltage is greater than a fully charged voltage of the battery, and applying the charging voltage for the period of time is sufficient to cause a zero volt crossing potential of the battery to increase to above a decomposition potential of the positive active material.

  • Publication number: 20180159361
    Abstract: Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue. In one example, a temperature sensor may sense a temperature of a portion of a device, wherein the portion is non-thermally coupled to the temperature sensor. A processor may then control charging of the rechargeable power source based on the sensed temperature.

  • Patent number: 9899710
    Abstract: A method for producing a battery includes providing a battery having a positive electrode, a negative electrode, and an electrolyte that includes a solvent and a salt. The capacity of the negative electrode is less than that of the positive electrode and the negative electrode includes an active material having an average potential versus a lithium reference electrode of greater than approximately 0.2 volts. The method also includes applying an initial charge to the battery at a voltage that is greater than a fully charged voltage of the battery for a sufficient amount of time to cause at least a portion of the solvent to undergo a reduction reaction. The step of applying an initial charge to the battery acts to increase the irreversible capacity loss of the battery during the initial charge and provides the battery with enhanced tolerance to deep discharge conditions.
