Description

Technical Field

[0001] The utility model belongs to the technical field of a test tooling, and relates to a battery simulation test tooling. Background Art

[0002] A fuel cell is a chemical device that directly converts the chemical energy of a fuel into electrical energy. Among them, fuel cell vehicles have developed rapidly in the new energy vehicle industry due to advantages such as fast startup rate, high energy conversion efficiency, and environmental friendliness. When assembling a fuel cell, it is necessary to maintain a certain pressure inside the fuel cell. Different pressure magnitudes have different effects on the working state of the fuel cell. Therefore, performance debugging verification is required. However, in the existing detection, components are stacked and the tooling is tightened and fixed through corresponding pressing methods for corresponding tests. During the test process, the pressure cannot be adjusted and controlled for the fuel cell, and there is a large gap between the test result and the expected test purpose. Summary of the Invention

During the test process, the magnitude of the pressure exerted by the applying component on the battery is applied, so that the pressure sensor detects the pressure value received by the battery and the performance of the battery is tested. The test result is authentic, and the reliability of the test result of the battery simulation test tooling is improved. The structure is simple and the operation is convenient.
