A hearing device and a method for charging a hearing device is provided, the hearing device comprising an interface comprising a wireless transceiver configured for wireless communication with a charging device; and a power module comprising a charging controller and a receiving coil for wireless charging of a battery positioned in the hearing device; wherein the charging controller is configured to: obtain a first charging parameter; determine a primary charging scheme based on the first charging parameter; and transmit a primary charging indicator indicative of the primary charging scheme via the wireless transceiver.

Hearing device and related method of wireless charging

The present disclosure relates to an application to be executed by an electronic device. The electronic device communicates with a hearing device worn by a user. The hearing device comprises a battery and a processing unit configured to receive an input signal and provide a processed output signal for compensating a hearing loss of the user. The application is configured for transmitting a status request from the electronic device to the hearing device, receiving, at the electronic device, a status response from the hearing device, and generating a notification representing instructions for charging the battery. The notification is generated based on the received status response and predetermined settings of the application.

Method for charging a battery of a hearing device

A hearing aid includes: an input transducer configured to output an audio signal based on a signal applied to the input transducer; a processor configured to compensate a hearing loss of a user of the hearing aid and output a hearing loss compensated audio signal; an output transducer configured to output an auditory output signal based on the hearing loss compensated audio signal, wherein the auditory output signal is to be received by a human auditory system; a wireless communication unit configured to communicate wirelessly with another device; an energy storage unit coupled to supply the wireless communication unit with power; and a current limiting unit coupled for control of replenishment of the energy storage unit with energy from a power supply.

Hearing aid radio power supply

A hearing aid and a method for operating a hearing aid is disclosed. The hearing aid comprises a processor configured to compensate for a hearing loss; a battery unit comprising a rechargeable battery; a wireless receiver element for receipt of a wireless power signal, the wireless receiver element configured to convert the wireless power signal to an electrical power signal; a detector assembly for provision of one or more detector signals including a first detector signal; and a power controller connected to the processor and the detector assembly, wherein the power controller is configured to select a power mode of the hearing aid from a plurality of power modes based on the first detector signal and apply the selected power mode in the hearing aid.

Hearing aid with power management

A system includes: an external input device having a housing accommodating at least two telecoils having different orientations with respect to the housing, and an orientation sensor configured for sensing an orientation of the housing; and a selector configured for controlling connection of one of the at least two telecoils to an input of a hearing aid based on the sensed orientation.

External input device for a hearing aid

A battery charger () for charging a rechargeable battery () which is located in a hearing aid (), the battery charger () includes a power supply for supplying a charging current to the rechargeable battery (), a hearing aid connector for reception and accommodation of the hearing aid (), the connector having a set of first electrical terminals () connected with the power supply and positioned for connection with the rechargeable battery () when the hearing aid () is positioned in the connector, and an actuator () that is adapted for providing access to the battery () for connection with the first electrical terminals () when the hearing aid () is positioned in the connector.

Hearing aid battery charger

Digitally controlled switch mode power supply for charging rechargeable

In a system and method for charging a rechargeable battery having a protection circuit, the rechargeable battery operates according to a model that includes an ideal battery and an internal resistance. In the model, an electrode voltage develops across the ideal battery. An internal voltage drop equal to the difference between this electrode voltage and the battery voltage is developed across the internal resistance. The battery is charged with a charging voltage that may exceed the threshold voltage and the electrode voltage. The charging system and method ensures that (1) the voltage at the protection circuit is kept below the threshold voltage and (2) the electrode voltage is kept below the end-of-charge voltage.
