  • a visual display This may have an LED array or a liquid crystal display with segments, with which the state of charge is displayed during the course of a charging process. For example, it is known to provide a series of light-emitting diodes. The completion of the charging process is represented for example by the fact that all LEDs are lit or all segments are activated. Such visual displays occasionally require a user to take a close look at the current state of charge, which may have changed little when charging secondary batteries even after hours. However, a secondary battery can be heavily charged even by a rapid charging within a relatively short time. From DE 195 30 594 small electrical appliances are known with a double-layer capacitor as energy storage. Typical charging times for a double-layer capacitor are on the order of seconds. It is also known to acoustically indicate the charging process of a high-voltage capacitor, cf. DE 7808292 U1.

  • Suitable small electrical appliances are, for example, electric shavers, electric toothbrushes or infrared ear thermometers, which are usually only a few minutes per day in operation, and their daily power consumption can therefore be easily covered by a double-layer capacitor.
  • the user Before using such a small electronic device, the user will put the small electrical device on a charging station for only a few seconds, and then use the device already.
  • the charging of the double-layer capacitor can be done in a conventional manner, for example via contacts or inductive coupling of the small electrical appliance with a charging station.

  • the acoustic signal consists for example of a repeated beep. It is particularly advantageous if the beep is repeated more slowly at the beginning of the charging process than at the end of the charging process or vice versa. Of course, a continuous tone can also be used. Additionally or alternatively, the frequency (pitch) and / or the amplitude (volume) of the sound may change during the charging process. The end of the charging process is reached when the acoustic signal stops again. Assuming a charging time of only a few seconds, you will not feel the acoustic signal disturbing.
  • the frequency of the acoustic signal can be changed during the charging process so that the change is proportional or inversely proportional to, for example, the stored amount of charge or the voltage of the energy storage.

  • a speech signal is generated during the charging process, which consists of a backward counted number sequence, the first Number depends on the state of charge of the energy storage at the beginning of the charging process. For example, in a fully-discharged double-layer capacitor, the signal "Ten - Nine - Eight - Seven - Six - Five - Four - Three - Two - One - Done" is output, the duration of the voice signal being tuned to the duration of the charge. Since the state of charge of a double-layer capacitor can be easily determined on the basis of its voltage, the speech signal can also be selected correspondingly shorter if the double-layer capacitor is not completely discharged at the beginning of the charging process. Preferably, the speech signal then starts with a correspondingly smaller number than "ten".
