Battery information acquisition assembly

The utility model provides a battery information acquisition assembly, and the assembly comprises an electric wire which comprises an acquisition end; the metal shell is fixed at the acquisition end of the electric wire; the expansion head is fixed to the metal shell, and the expansion head comprises a connecting part fixed to the metal shell and a deformation part located on the side, away from the metal shell, of the connecting part. According to the battery information acquisition assembly, the expansion head fixed with the metal shell is arranged, so that a user can compress the deformation part of the expansion head to enable the expansion head to be easily inserted into the corresponding mounting hole of the to-be-detected component, and after the expansion head is inserted into the mounting hole, the deformation part naturally expands, so that the expansion head and the whole battery information acquisition assembly can be stably mounted at the to-be-detected point position; after the acquisition and m
