Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle battery detection, and more specifically to a new energy power battery detection and diagnosis device. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources and integrate advanced technologies in vehicle power control and driving to form advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. In new energy vehicles, batteries are very important components. The service life of batteries is related to their air tightness. When the battery air tightness is poor, air can easily penetrate into the battery. The materials in the battery are affected by moisture in the air, which can easily reduce the battery power. In severe cases, it can also cause battery damage. In order to ensure the safety and endurance of new energy vehicles, air tightness testing operations are required before the battery leaves the factory. However, the existing air tightness testing device cannot well discharge the pressurized gas in the device after the test is completed. It is easy to be dangerous to open it directly, and the air cannot be filtered well when it is discharged, so that the water vapor in the air can easily enter the device and the battery, which is not conducive to the service life of the device and the tested battery. For this purpose, a new energy power battery detection and diagnosis device is provided. Utility Model Content

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model is provided with a pressure relief device, which is conducive to discharging the pressurized gas inside the placement box. When the test is completed, the pressing column can be pressed inwardly, and the pressing column drives the moving block to move inside the placement box, so that one side of the sealing gasket leaves the inner wall of the placement box, so that the air can pass through the air groove and be discharged through the pressure relief port, so that the air pressure inside and outside is consistent, which prevents danger when opening. After the pressure relief is completed, the pressing column is released, and the sealing gasket is pressed against the inner wall of the placement box under the action of the spring, so as to ensure the isolation of the inside and outside air and prevent the outside air from entering when not in use. Moreover, due to the high internal air pressure during pressurization, the sealing gasket can be more stably pressed against the inner wall of the placement box under the action of the air pressure, so as to ensure the sealing during the test.

[0012] 2. The utility model is provided with an air intake device, which is conducive to filtering the exhausted air. The dustproof plate is used for dust prevention, so that the air entering the placement box is cleaner. The moisture absorption column is used to absorb moisture in the air to ensure that the air entering the placement box is drier, preventing moisture in the air from entering the interior of the device and the battery, thereby affecting the service life of the device and the battery under test.
