[0002] In recent years, batteries have been widely used in various fields such as electronic products due to their excellent performance such as high energy density, high voltage, high cycle, high safety, and green environmental protection. After the battery is completed, in order to verify the quality and performance of the product battery and further clear the transmission path of ions between the positive and negative electrodes, improve the cycle performance of the battery during later use, and ensure the safety performance of the product after leaving the factory, the battery needs to be charged and discharged several times before shipment. This process is called "capacity separation".

[0003] The existing battery capacity cabinet has a multi-layer structure, and each layer can hold multiple batteries for capacity separation. The battery capacity separation station is fixed, and the test fixture is also fixed. In other words, this type of capacity separation cabinet can only adapt to the capacity separation of a certain type of battery. Its applicability is too poor and it cannot meet the capacity separation needs of different types of batteries. Summary of the Invention

Multiple batteries can be placed on the same layer for capacity division; after the positive and negative poles of the battery correspond to the connecting terminals on the fixed plate, the pressing plate is pushed by a push-pull quick clamp to make the pressing plate close to the fixed plate, and finally the battery is fixed and clamped between the pressing plate and the fixed plate, ensuring reliable contact between the positive and negative poles of the battery and the connecting terminals. The connecting terminals are connected to the detection equipment through cables; for the capacity division of batteries of different sizes, the connecting terminals are moved in the elongated holes, and the contact with the battery is achieved by changing the position of the connecting terminals.
