    Abstract: A battery module for a hearing device includes a secondary cell and two contact elements for making contact with the secondary cell at two different potential areas. A fuse which is arranged at a short distance from the contact element that is assigned to a positive potential. A copper jacket surrounds the secondary cell, and a ferrite jacket is arranged on the outside of the copper jacket. An induction coil is arranged on the outside of the ferrite jacket and is configured to inductively receive energy for charging the battery module. A resonant capacitor is coupled to the induction coil at a short distance from the latter. A thermistor for monitoring a cell temperature is arranged with electrical insulation from the secondary cell but is coupled to the latter with low thermal resistance using heat-transfer capability.

    Abstract: 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.

    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.
