Patent attributes
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.
