US 2014/0178720 A1 · MEASURING METHOD FOR AN ELECTROCHEMICAL ENERGY STORAGE DEVICE AND MEASURING APPARATUS

Abstract

The measurement method according to the invention for an electrochemical energy storage device involves the electrochemical energy storage device being held (S1) and having contact made with it (S2) in a holding device. The electrochemical energy storage device is charged (S3) to a predetermined first charge state. The electrochemical energy storage device is discharged (S4) to a predetermined second charge state. A measuring device is used to capture (S5) at least one measured value for a physical parameter of the electrochemical energy storage device, with the physical parameter allowing the operating state of the electrochemical energy storage device to be inferred.
