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.
Why do batteries need to be sealed?
The sealing components used also have to be chemically stable toward organic electrolytes. In addition, during the battery’s entire service life, the sealing mater-ial must not leach out contaminating substances into the battery electrolyte as this could have a long-term negative influence on the cells’ electrochemistry.
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?
Why is EVs battery pack sealing important?
The sealing of the EVS battery pack is very critical to the battery pack’s safety in the box. New sealing structures and sealing materials are constantly emerging. Battery pack sealing is constantly being explored, evolved, and improved.
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.
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.
