Abstract

A method for fault tracing in automatically operating electronic measurement and test arrangements for a large number of electrochemical elements, wherein holders for the electrochemical elements are provided on the measurement and test arrangements and wherein cell simulators are provided with an external shape and size, including electrical connections, which approximately simulate one of the electrochemical elements to be tested, and contain test electronics, with a behaviour of the cell simulators with inverse polarity differing to a major extent from a behaviour with polarity based on the application, including the steps of inserting of the cell simulators into the holders, activating one of the cell simulators and applying a measurement current applied to it, measuring the voltage on the cell simulator and comparing the voltage with the nominal voltage predetermined for the cell simulator.

Claims (7)

1. A method for fault tracing in automatically operating electronic measurement and test arrangements for a large number of electrochemical elements, wherein holders for said electrochemical elements are provided on said measurement and test arrangements and wherein cell simulators are provided with an external shape and size, including electrical connections, which approximately simulate one of said electrochemical elements to be tested, and contain test electronics, with a behaviour of said cell simulators with inverse polarity differing to a major extent from a behaviour with polarity based on the application, comprising:

inserting said cell simulators into said holders,

activating one of said cell simulators and applying a measurement current applied to it,

measuring the voltage on said cell simulator and comparing the voltage with the nominal voltage predetermined for said cell simulator.

2. The method according to claim 1 , wherein, before measurement of said voltage on said cell simulator, a measurement current is compared in predetermined time intervals with said predetermined nominal value.

3. The method according to claim 1 , wherein two or more of said cell simulators are arranged adjacent to one another.

4. The method according to claim 3 , wherein adjacent cell simulators each have a different behaviour.
