Airtightness of rack-mounted lithium battery pack

The airtightness level of the battery pack case is usually required to reach IP67 or IP68, which means that the battery pack case needs to be completely protected from dust ingress (dustproof level 6) and can be immersed in water at a certain pressure for a period of time without water ingress to a harmful level (waterproof level 7).

FAQS about Airtightness of rack-mounted lithium battery pack

Why do lithium ion batteries need air tightness tests?

Lithium-ion battery air tightness tests play a crucial role in ensuring long-term performance and durability. Preventing leaks in battery manufacturing through reliable air-tightness testing methods ensures that battery packs perform optimally, safeguarding both performance and safety.

Why do energy storage batteries need air tightness tests?

Energy storage batteries require stringent leak detection for battery performance and battery safety and air tightness testing due to potential hazards and degradation caused by leaks. Lithium-ion battery air tightness tests play a crucial role in ensuring long-term performance and durability.

What is battery pack air tightness assessment?

For the battery pack air tightness assessment, there are two indicators: pressure drop value and leakage rate. The pressure drop value represents the change in internal pressure during testing, while the leakage rate measures the rate of leakage. These factors are critical in battery quality control through air tightness testing.

How to test battery air tightness?

The combination of the upper and lower boxes, high-voltage electrical connectors, water-cooled pipes, and heat dissipation ports (waterproof and breathable holes) are the key areas for battery air tightness testing. A. The battery pack has a large area, small internal space, and a thin shell that can withstand less pressure. B.

What is air leakage testing in batteries?

The air leakage testing in batteries primarily uses dry compressed air to inflate (positive pressure) or deflate (negative pressure) the tested object, determining if the body is leaking. Leaks cannot be directly measured but can be inferred from changes in pressure. If the pressure inside the object drops significantly, it indicates a leak.
