Definitions

  • the invention relates to a Hörinstrumentsystem with rechargeable battery, or short battery.
  • Rechargeable batteries can be used in particular for mobile devices.
  • mobile devices are for example hearing instruments into consideration.
  • Hearing instruments can be designed for example as hearing aids.
  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified for compensation or therapy of the respective hearing impairment. It consists in principle of one or more input transducers, of a signal processing device, of an amplification device, and of an output transducer.
  • the input transducer is typically a sound receiver, e.g. a microphone, and / or an electromagnetic receiver, e.g. an induction coil.
  • the output transducer is usually as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B.
  • the output transducer generates output signals that are routed to the patient's ear and are intended to produce a hearing sensation in the patient.
  • the amplifier is usually integrated in the signal processing device.
  • the hearing aid is powered by a battery integrated into the hearing aid housing.
  • the essential components of a hearing aid are usually arranged on a printed circuit board as a circuit carrier or connected thereto.
  • Tinnitus maskers are used to treat tinnitus patients. They generate from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic output signals, which can contribute to reducing the perception of disturbing tinnitus or other ear noises.
  • Hearing instruments can also be designed as telephones, mobile phones, headsets, headphones, MP3 players or other mobile telecommunications or consumer electronics devices.
  • Hearing instruments have traditionally been operated with non-rechargeable batteries. Frequently batteries are used based on Zn-air cells, which have a high energy density.
  • the power supply including the battery itself is integrated in the hearing instrument.
  • the battery In the hearing instrument, the battery is covered by a door or flap and thereby shielded from the environment. Through the door or flap, the battery can be inserted and removed.
  • the hearing instrument has electrical contacts that contact the battery. These are clamped in a holder and not firmly connected to the hearing instrument. However, since this door does not close completely tight, impurities, moisture and especially chemically aggressive earwax can get into the battery compartment and thus into the hearing instrument and cause corrosion or other problems there.
  • NiMH batteries have the advantage that they have the same voltage level (1.2V) as the usual non-rechargeable batteries in hearing instruments, and that the form factor is the same.
  • 1.2V voltage level
  • a major disadvantage of NiMH batteries is that they have a relatively short life span, that their capacity is limited, and that they react sensitively to high temperatures during charging. Because of the difficulties mentioned, a change of the battery must continue allows what an openable and thus not completely tight battery compartment requires.
  • Li-Ion batteries are sensitive to a variety of influences, such as extreme temperatures, high charging temperatures, overcharging or over-discharging. In addition, they benefit in particular from suitable charge current cycles and trickle current cycles. That's why Li-Ion batteries are used to advantage with custom charging and protection circuitry to optimize capacity and life.
  • the hearing aid is additionally connected via an IR coupling to the charger.
  • the IR connection controls the start and end of the charging process so that the charger automatically determines or receives information regarding the battery.
  • EOL end-of-life detection
  • the charge state of the rechargeable battery would have to be determined or the impending exhaustion of the rechargeable battery charge would have to be detected.
  • the EOL detection is adapted to the current battery systems, whose remaining battery life is determined by the hearing instrument based on the battery voltage.
  • other battery systems, such as batteries may exhibit a different EOL behavior so that EOL detection may not work properly using such systems.
  • the size requirements (especially thickness) of the battery are for mobile devices, especially for hearing instruments, very strict. On the other hand, the duration of hearing instruments should be at least one day with 16-20 hours - ideally more. To comply with the size specifications, all parts of the power supply must be matched as optimally as possible. This is particularly true of the battery itself, as it adds significantly to the overall size of the power supply, and equally applies to rechargeable batteries. It also includes any intended charging and protection circuits.
  • the object of the invention is to optimize the Alltasgsnutzen a battery, in particular by an EOL detection, and the performance and life of a battery, especially in sensitive systems such as Li-ion batteries in a hearing instrument system.
  • a basic idea of the invention is to document information regarding the battery, for example battery capacity, state of charge, events during use of the battery in daily operation, operating time and charging cycles.
  • the information should be made available, for example, during operation and while the battery is being charged.
  • Important usage information from ongoing operations, such as the occurrence of errors, are stored in the hearing instrument and to the charger or a hearing instrument fitting software to hand over. In response to such information, hearing instrument parameters may be adjusted to the state of the battery.

While wireless transmission is too energy consuming and not necessary at the same time within the hearing instrument, it is desirable for connection to the charging system.
