Abstract
Apparatus () and method for testing cell contact of battery cells () of a battery module (), which battery cells are electrically connected in parallel via a contacting system (). The apparatus includes a sensor positioning system () for positioning a sensor device () at a plurality of test points () of the battery module, which is movable along a longitudinal axis (X), a transverse axis (Y), and a vertical axis (Z), and a current generation circuit () for generating a battery cell current (I), which is a discharging current from the battery cell or a charging current into the battery cell. The sensor device includes at least one field sensor (), which, after the sensor device is positioned at one of the test points, detects a field in the region of the test point, which is generated by the battery cell current generated with the current generation circuit.
