6 FAQs about [What is the material of the battery cabinet seal ring ]

What is a sealed battery box?

The design of the sealed box focuses on the flow of battery cooling airflow, and any leakage must be avoided to ensure consistent performance. To achieve this, the upper cover and the lower bottom of the battery box must be free from any perforations or gaps, and a gasket should be added between them during assembly.

How to choose a sealing ring?

H1 – The height of the sealing plane of the upper and lower covers of the battery pack after the sealing ring is compressed (mm). When selecting the compression ratio of the sealing ring, the following two aspects should be considered: (1) There should be sufficient sealing contact area.

Why does a battery case need a seal?

The right seal design, when considered in parallel with the case design, can save production costs through design for manufacturability. A durable seal around the battery case allows a modular design, where individual cells can be replaced if required. This is critical for the economic feasibility of these power units. What does a battery box do?

What happens if a battery case seal is too high?

It is important to obtain the correct force required on the fixings to compress the seal in the battery case. If the compressive force is too low the seal may hold the case open, or too high may cause the seal to over compress and split or damage to the carbon composite.

How many sealing layers are there in a sealing ring?

There is a groove in the middle of the sealing ring, forming the sealing ring in the shape of No. 2 in Figure 3. This allows the sealing ring to form two sealing layers, the inner sealing layer being the main sealing layer. The outer sealing layer is the auxiliary sealing layer.

Do EVs batteries need to be sealed?

EVS Battery Pack Sealing Structure Analysis As the output voltage of a pure EVS power battery pack can reach 200V or more, it is essential to ensure that the battery box is properly sealed and waterproof to prevent water ingress and subsequent short circuits. To meet this requirement, the battery box must comply with IP67 standards.
