Why does the battery PACK have to be tested for air tightness?

What is the air tightness test of battery PACK package?

Air tightness testing is an important process for testing the sealing performance of battery PACK packages. It aims to ensure that there is no abnormal leakage between the inside of the battery module or battery pack and the external environment. Through the air tightness test, the tightness of key parts such as welding points and sealing rings can be detected to prevent the entry of external air, moisture or dust, thereby protecting the safety and stability of the internal components of the battery.

Characteristics of battery PACK air tightness test

1. Accuracy: The high-precision pressure sensor is used to detect small leaks of internal gas and can identify nano-scale air tightness defects.

2. Reliability: Provide strict protection for battery modules to prevent battery performance degradation or safety hazards caused by water vapor intrusion.

3. High efficiency: Air tightness testing usually uses automated equipment, which can quickly complete the testing of a large number of products.

4. Non-destructive: The testing process does not cause any damage to the product and ensures the integrity of the finished product.

Application of battery PACK air tightness test

1. New energy vehicle batteries: ensure long-term stable operation of batteries in complex environments (such as high humidity or dusty conditions).

2. Energy storage system: Improve the safety and service life of energy storage equipment.

3. Industrial equipment: For battery components with high environmental adaptability requirements, air tightness testing is a key link in quality assurance.

Price of battery PACK air tightness test

The cost of air tightness testing is mainly affected by the following factors:

1. Test equipment cost: The accuracy, automation level and brand of the equipment affect the price.

2. Process complexity: The size, sealing structure and materials of different products will affect the difficulty of the testing process.

3. Testing volume requirements: Batch testing requirements will reduce the unit cost, but the initial equipment investment will be higher.
