This equipment is specifically designed for the overall sealing performance test of large-capacity battery casings in heavy-duty trucks. It adopts high-sensitivity differential pressure detection technology and precisely tests under a low-pressure condition of 10kPa. The device is equipped with a large dedicated sealing fixture, which can quickly adapt to battery boxes of different sizes in heavy-duty trucks and automatically complete the processes of inflation, pressure stabilization, detection, and exhaust. For large-volume cavities, the equipment optimizes the inflation algorithm to effectively eliminate deformation interference and ensure the accurate identification of minor leaks. The testing process is fast and non-destructive, supports data traceability and connection with the MES system, and fully meets the IP67/IP68 protection level standards, providing a solid guarantee for the safe operation of heavy-duty truck battery power systems.
This equipment is specially designed for the airtightness testing of controller housings, adopting a direct pressure testing principle and conducting precise tests at a pressure of 50kpa. The equipment is equipped with a dedicated sealing fixture that can quickly fix the controller housing and seal the interfaces, automatically completing the entire process of inflation, pressure maintenance, testing, and exhaust. The testing process only takes tens of seconds, and the airtightness of the housing is accurately determined by monitoring pressure changes through an airtightness meter. The equipment has a simple operation interface, supports parameter presetting and data recording, and is suitable for airtightness testing of various types of housings such as automotive suspension controllers and electric vehicle controllers, ensuring that products meet IP protection level requirements and effectively improving production quality and efficiency.
The cold battery bipolar plate airtightness testing equipment is a crucial device used to verify the sealing performance of bipolar plates. It employs the pressure decay leak detection method, filling gas into the flow channels within the plate through a dedicated tool, and automatically monitoring pressure changes or leakage amounts to accurately identify internal or external leaks, ensuring the safety and efficiency of the battery system.
