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.
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.
3.1 Air tightness test The main method for airtightness testing for EVS batteries is to use a gas pressurization system, connect the product to the airtightness tester by using a quick connector, and then charge the gas into the battery box to be tested. After the air pressure stabilizes, observe the change in internal pressure over time.
For this new market, battery leak testing is essential for electric vehicles, for battery packs any leakage can compromise safety, performance, and longevity of the system.
