Abstract

The invention discloses a battery module detection device. The battery module detection device comprises a displacement sensor used for detecting the deformation of an end plate of a battery module inthe charging and discharging process, and a base used for fixing the displacement sensor and the battery module to be detected. By detecting the deformation of the end plates of the battery modules,the structural stability and the application safety of the battery modules can be determined, and data support can be provided for the arrangement distance between the adjacent end plates of the adjacent battery modules, so that the design of the battery modules can be more reasonable.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to a detection device for battery modules. Background technique [0002] The battery module includes a casing and a plurality of battery cells located in the casing, and the casing includes two end plates (located at both ends of the length of the casing) and two side plates (located at both sides of the width of the casing). During the charging and discharging process of the battery module, the battery cells will swell, and when the swelling is severe, it will contact the end plate, resulting in deformation of the end plate, affecting the service life and structural stability of the battery module. [0003] Therefore, when designing a battery module, it is necessary to reasonably consider the deformation resistance of the end plates and the layout distance between adjacent end plates of adjacent battery modules. Contents of the invention [0004] The object of the presen...
