Description

Technical Field

Background Art

[0002] Batteries need to undergo performance testing before leaving the factory. Among the many tests, one of them is to place the batteries in a constant temperature water bath for performance testing. The performance testing requirement of the constant temperature water bath is that the top of the battery needs to be 15mm to 25mm higher than the water level. Due to the large number of battery types, the battery heights vary, and the order sizes of different countries are different, resulting in different batches of batteries with different heights. When performing performance testing in the laboratory, different types of batteries are placed in the same water bath for the same performance test. Since the liquid level is fixed, and the heights of each battery are different, it is impossible to ensure that each battery can maintain a suitable distance from the liquid level. This results in the internal temperature of the battery not meeting the requirements, which will affect the battery. Battery test data; the current measure taken by the laboratory is to set the liquid level according to the battery height of 200mm in the water bath, and place pads under other batteries that are not high enough to ensure that the batteries are not submerged. Although this method can ensure normal battery performance testing, in the long run, the battery liquid level height cannot be guaranteed to meet the standard requirements, and the consistency of the liquid level height of the same model battery cannot be guaranteed each time it is tested. The difference in battery height and the change in liquid level height are all variable parameters; the workload of adjusting the distance between the battery and the liquid level one by one is huge, which affects the progress and efficiency of the test and increases the labor intensity of the staff; therefore, a height adjustment device is needed, which is required to be able to efficiently adjust the height of the battery, thereby reducing the labor intensity of the staff.
