The airtightness of automotive power batteries directly affects the quality of the car, so strict sealing requirements are required during the production process to ensure their airtightness. Airtightness is one of the important factors affecting product quality.
According to the characteristics of the battery, differential pressure airtightness detection technology is adopted. The differential pressure leakage detection method is to fill compressed gas into the tested component and the standard chamber, maintain it for a certain period of time, detect pressure changes through pressure sensors, compare the pressure values of the standard sample (sealed intact) under the same working conditions, and determine whether the tested object is leaking.
Specific experimental methods:
1. The airtightness testing equipment for power batteries adopts indirect testing methods, customizing molds according to the structure of the power battery, inflating, and testing the sealing of the battery.
2. Activate the power battery airtightness detection device detection button, press down on the upper cylinder to block the A port of the product, seal the B port with the left cylinder action, and flush in the set detection pressure value.
3. The real-time detection value of the battery airtightness testing equipment is displayed through the data processing system, and within the set time, it undergoes inflation, voltage stabilization, and testing processes. Qualified products will display PASS and a green light on the display screen of the power battery airtightness testing equipment, while unqualified products will display FAIL and a red light on the display screen of the power battery airtightness testing equipment.
4. The battery airtightness testing equipment has data storage function, can export and upload, adjustable pressure, and can be set according to requirements.
