  • Publication number: 20250039593
    Abstract: A method for operating an inductive charging device of a hearing instrument. The charging device includes a voltage source and an oscillating circuit connected thereto, a charging coil and a capacitance. The capacitance has a main capacitor and an adjustment branch connected in parallel therewith. For different states of the adjustment branch, which differ from one another on the basis of the capacitance of the adjustment branch, a value that denotes an electrical current resulting from the charging coil is recorded. That state in which the electrical current corresponding to the value is at a maximum is determined, and the adjustment branch is set to correspond to the state. There is also described an inductive charging device and a corresponding system.

  • Publication number: 20240393404
    Abstract: A state of health of a battery cell used in a hearing instrument is ascertained. For each of a plurality of charging cycles, a battery manager of the hearing instrument ascertains a charge transferred to the battery cell and a number of charging characteristic values that provides information about the change in a state of charge of the battery cell brought about by the charge. Based on the transferred charge and the charging characteristic values a capacity characteristic value is ascertained that forms a characteristic variable for a present charging capability of the battery cell. A signal processor averages respective capacity characteristic values of at least some past charging cycles at a specific time and calculates an averaged charging capacity. The averaged charging capacity is compared with a reference value representing an original capacity of the battery cell to determine the state of health of the battery cell.

  • Patent number: 12089004
    Abstract: A method includes connecting a device to a charger and providing wireless charging in a state of charge by transferring energy wirelessly from a transmitter module of the charger to a reception module of the device. The device has a state of discharge in which energy is consumed. The device includes a charging connector, to which a charging input voltage adjustable by the charger is applied for charging. The device includes a switching connector for turning the device on and off. The device includes a switch connected to the switching connector and being switchable by the charging input voltage by setting the charging input voltage to an intermediate voltage. The charger sets the charging input voltage to the intermediate voltage for switching the switch and transitioning the device into an off state with the device turned off. A corresponding device and charger are also provided.

  • Patent number: 12041422
    Abstract: A battery module for a hearing device is configured for an inductive resonance charging method. The battery module includes a secondary cell and a blocking sleeve that encloses the secondary cell to shield the secondary cell against a magnetic field. A jacket formed from permeable material is arranged on the outside of the blocking sleeve. An induction coil, which is arranged on the outside of the jacket, is configured to receive energy inductively. The induction coil and the jacket form a receiving antenna for receiving energy. The induction coil is arranged such that a coil axis of the induction coil is oriented radially with respect to the secondary cell.

  • Publication number: 20220394372
    Abstract: A method for initializing a long-term-storage mode for a hearing instrument having a rechargeable battery cell includes predetermining an upper limiting value of a parameter for a state of charge of the rechargeable battery cell for long-term storage of the hearing instrument. An actual value, actually present, of the parameter for the state of charge is measured within an activation routine for long-term storage. The measured actual value of the parameter for the state of charge is compared with the upper limiting value of the parameter for the state of charge, and if the measured actual value of the parameter lies above the upper limiting value, the battery cell is discharged at least until the parameter has reached the predetermined upper limiting value, and the hearing instrument is placed into a long-term-storage mode. A hearing instrument is also provided.
