摘要

The present invention relates to a device for leak testing a battery cell (10, 10 '), characterized by a detection device for detecting (215) a first measured value of a parameter of the battery cell (10, 10'), wherein the parameter is a mass, a volume, a Dimension or thickness of the battery cell (10, 10 ') and, after a period of time, detecting (255) a second measured value of the parameter of the battery cell (10, 10'); a comparison device for comparing (265) the second measured value with the first measured value; and determining means for, when the second measurement and the first measurement differ by more than a predetermined threshold (265.1), determining (270) that the battery cell (10; 10 ') is leaking, or when the second measurement and the first measurement differ by less than the predetermined threshold (265.2), determining (275) that the battery cell (10; 10 ') is leakproof, a method, a computer program, a computer program product, a battery cell (10; 10'), a battery module, a battery, a battery system and a vehicle.
