摘要： 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.

摘要： A battery module for a hearing device is configured for inductive resonance charging. The battery module has a secondary cell, a blocking sleeve that encloses the secondary cell and shields the secondary cell against a magnetic field, a jacket formed from permeable material outside the blocking sleeve, and an induction coil outside the jacket for receiving energy inductively. The induction coil and the jacket form a receiving antenna for receiving the energy. The material and/or the geometric structure of the blocking sleeve, the jacket made of permeable material, and/or the induction coil is/are additionally selected in such a way that the battery module, in particular the induction coil, has a quality factor of at least 35 for receiving energy at a predetermined value of a charging frequency that is employed by a charging device that generates a magnetic alternating field.
