However, the conventional measurement of the thickness of the battery needs to be performed after the pressure maintaining is completed, which results in a long thickness measurement time of the power battery, and thus the thickness measurement efficiency of the power battery is reduced, and the detection cost of the power battery is increased.
In order to improve the pressure maintaining thickness measuring efficiency of the power battery, referring to fig. 6, the power battery pressure maintaining mechanism 320 further includes a battery thickness measuring assembly 32d. The battery thickness measuring assembly 32d includes a power source 322, a pushing member 324, and a thickness measuring member 321.

In this embodiment, in the process that the pushing motor 3222 pushes the pushing pressing plate 3224 to move toward the battery pressing plate 32c, the pressure sensor 3214 detects the pressure applied to the power battery by the telescopic cylinder of the pushing motor 3222 in real time, it is ensured that the pressure applied to the power battery is consistent during pressure maintaining, and when the power battery performs pressure maintaining, the thickness measuring sensor 3212 moves along with the pushing pressing plate 3224, according to the change of the moving distance, the acquisition of the thickness of the power battery after pressure maintaining is completed is realized, it is convenient to detect the thickness of the power battery while the pressure maintaining is completed, the thickness measuring time of the power battery is reduced, and the pressure maintaining thickness measuring efficiency of the power battery is improved. The thickness measurement of the power battery can be performed before the pressure maintaining operation or during the pressure maintaining operation, and particularly, the pressure maintaining thickness of the power battery is measured while the pressure maintaining operation is completed.
