Abstract
The invention relates to a device () for testing at least one battery cell (), more particularly of a secondary battery, the device comprising: —a first plate () and a second plate (), the battery cell () being clamped between the two plates (), which are preferably substantially rectangular, and at least one plate () being pressed against the battery cell () with a defined mechanical pressing force (F); and—at least one force-measuring element () disposed between one plate () and at least one pressing device (), for measuring a reaction force (R) between the battery cell () and the pressing device (). According to the invention, in order to increase the accuracy and the informative value of tests of battery cells (), at least one change in a thickness (D) of the battery cell () can be measured, preferably simultaneously with the reaction force (R), by means of at least one displacement-measuring element ().
