Technical Field

[0001] The utility model belongs to the technical field of battery detection, and in particular relates to a cooling device for battery detection. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. It is necessary to test the charge and discharge cycle life of lithium batteries to determine how long the service life of lithium batteries is. Since lithium batteries need to test the cycle life, one charge and discharge is usually used as one cycle life. However, after one cycle, the battery will heat up, and at this time it is necessary to wait for the battery to return to the test temperature. The cycle life is usually divided into normal temperature cycle 25°C and high temperature cycle 45°C.

[0003] Most existing lithium batteries are cooled by natural cooling or air cooling during the testing process. However, natural cooling takes a long time, and air cooling will affect other batteries to be tested in the environment, causing differences in test results of other lithium batteries to be tested. Therefore, a cooling device for battery testing is proposed. Utility Model Content

[0006] As an improvement, the cooling coil is located in the middle of the clamping plate, and the length of the cooling coil inside the clamping plate is greater than 3 / 4 of the length of the clamping plate, and both ends of the cooling coil are located on one side of the clamping plate.

[0007] As an improvement, the plurality of connection holes are equidistantly arranged on the upper and lower sides of the clamping plate, and the diameters of the plurality of connection holes match the diameters of the bolts.

[0008] As an improvement, the length of the bolt is greater than the width of the battery body, and the other end of the bolt is threadedly connected to a first nut.

[0010] As an improvement, the screw is located on a side of the limiting plate close to the battery body and is connected to a second nut through a thread, and a gasket is provided between the second nut and the limiting plate.
