[0053] In this technical solution, the battery to be tested is placed on the base 1, and then the clamping mechanism 2 is used to limit the battery in the Y direction. The first electrical connection mechanism 4 and the second electrical connection mechanism 5 are connected to the charge and discharge equipment. The battery electrode terminal at one end of the battery in the X direction is electrically connected to the second electrical connection mechanism 5, and then the driving mechanism is used to drive the first electrical connection mechanism 4 to move closer to the battery in the X direction, so that the battery electrode terminal at the other end of the battery in the X direction is electrically connected to the first electrical connection mechanism 4, thereby enabling the battery to perform charge and discharge and voltage acquisition.

[0054] On the base 1, there are also two liquid cooling plates 3 placed. The two liquid cooling plates 3 are located inside the clamping mechanism 2.
