The waterproof and dustproof testing of lithium batteries is a crucial step in ensuring their normal functionality and safety in specific usage environments. This type of test is mainly based on the international protection level standard (IP Code), namely IPXX, where XX represents two numbers, one for dust and the other for water.

1、 Overview of Waterproof and Dustproof Testing Standards

1. IP67 standard

This is the minimum requirement of the country for the protection of power battery packs. Among them, "6" represents complete prevention of foreign objects and dust intrusion, which is the highest level of dust prevention; 7 "indicates that the device can be immersed in water for a short period of time under certain conditions (usually referring to soaking in 1 meter deep water for 30 minutes) without being affected.

2. IP65 standard

Although slightly lower than the requirements of IP67, it still means a very high level of protection. "6" also represents complete dust prevention, while "5" represents the ability to resist low-pressure water flow from any direction, suitable for outdoor or environments with water splashing risks.

2、 Waterproof and dustproof testing methods and requirements

1. Dust prevention test (first digit)

Dust chamber test: Use a dust chamber to simulate different dust environments and evaluate the dust prevention performance of the battery.

B Electrostatic adhesion test * *: By electrostatically attracting dust particles to adhere closely to the surface of the battery, check if any particles penetrate the battery casing.

2. Waterproof test (second digit)

Water spray test: For IPX5 rating, use a water spray device to spray water on the battery from all directions, simulating rain or water splashes.

Immersion test: For IPX7 rating, place the battery in water at a certain depth for a period of time to verify its waterproof sealing.

3. Airtightness testing: Using a high-precision airtightness tester, compressed air is used as the medium for testing, without the need for submerged testing. This method is efficient and accurate.

4. Environmental reliability testing: In addition to direct waterproof and dustproof testing, it also includes temperature cycling, humidity, salt spray and other tests to comprehensively evaluate the stability of the battery in harsh environments.

3、 Equipment and Technology

When conducting waterproof and dustproof tests on lithium battery packs, manufacturers usually use materials such as rubber seals and sealants to enhance their sealing performance.

2. Professional testing equipment, such as waterproof and dustproof test chambers, airtightness testers, etc., are used to simulate and test the performance of batteries under specific conditions.

In short, the waterproof performance of lithium batteries is an important factor that we need to consider when choosing lithium batteries. We can judge the waterproof performance of lithium batteries by waterproof standards, waterproof grades, and waterproof testing methods, and then choose products that are suitable for ourselves. In practical use, we also need to be careful not to soak lithium batteries in water for a long time, and when using chargers, we should pay attention to whether they have waterproof function.
