[0002] With the continuous development of science and technology, environmental pollution is becoming more and more serious, and cars are an important source of pollution. Therefore, for cars, using electricity will inevitably reduce environmental pollution. However, battery cell parameters are basic data for evaluating the quality of a battery cell, such as the open circuit voltage, internal resistance, weight, and volume of the battery cell.

The test principle and method itself are fine, but the test environment needs to be kept quiet and vibration-free, and the test process is relatively cumbersome. If the battery cell is not completely submerged in pure water, the battery cell touches the wall of the beaker, or the pure water is dirty, it will cause large errors in the test.
