Abstract: A switched-capacitor balancing and characterization system for balancing and characterization of a plurality of stacked battery cells includes at least one capacitor connectable to a plurality of battery cells via switches, configured to connect or disconnect the at least one capacitor to the battery cells and a processing unit configured to control the plurality of switches. The switched-capacitor balancing and characterization system is configured to perform simultaneous balancing and characterization of the battery cells. The disclosure further relates to a battery system comprising the switched-capacitor balancing and characterization system and the stack of battery cells and to a method for simultaneous balancing and characterization of a stack of battery cells, using a switched-capacitor balancing and characterization system and/or using a battery system.

Abstract: The application relates to a test device for a speaker module of a listening device, the speaker module comprising a speaker unit for converting an electric output signal to an output sound. The application further relates to a test system and to a data update device. An object of the present application is to provide an alternative scheme for identifying a receiver (speaker) in a listening device, e.g. a hearing aid. The problem is solved in that the test device being a separate device adapted for being electrically connected to the speaker module in a test situation, but not during normal operation of the listening device. An advantage of the invention is that it provides a flexible alternative to a receiver identification solution that is integrated into the listening device.
