Regarding air tightness testing in the new energy automobile industry, we have covered it in several cases we shared before. Products in these fields require special air tightness treatment.The country has special level requirements for testing in the field of new energy vehicles, and different products have different testing methods.Hirays Technology has also conducted in-depth research on air tightness testing in the new energy automobile industry, and customized equipment according to different testing needs, achieving high results.

Air tightness detector for automotive controllers

This time we will analyze the air tightness detection of automobile controllers, hoping to be helpful to everyone.

1. Air tightness detection and analysis of new energy vehicle controllers

1. The sealing of the car control needs to match the battery pack box structure and sealing ring. The upper and lower parts of the car controller need to be laser spliced ​​to achieve overall sealing, which is structural sealing.In addition, it will also use sealing aids such as sealing rings or sealants to help form a more airtight structure.

2. In the process of air tightness testing of automobile controllers, corresponding tests need to be carried out under different working conditions. When selecting corresponding tooling and molds, attention must be paid to the calculation methods, pressures, and software algorithms to accurately determine whether there are defects in the air tightness of automobile controllers and improve the production quality of new energy vehicles.

2. Demonstration of the air tightness testing process of automobile controllers

The product tested this time is a semi-finished car controller. It is tested whether the two parts inside the controller are sealed.

According to the customer's testing needs, we use direct detection methods to detect them.During the test, the instrument is used to directly inflate the inside of the product. This test is divided into three sets of procedures to complete the air tightness test of this product.

This inspection also used customized tooling and a sliding table top design, which is more suitable for the production of automated equipment.

Detailed display of air tightness detection of automobile controller

1. During detection, the instrument will fill a certain volume of dry and impurity-free gas into the cavity of the car controller, then cut off the compressed air supply, wait for a period of time to stabilize the pressure, and monitor the slight changes in air pressure in the detection environment after a set measurement time.The sensor transmits this information to the detection system, and finally through a series of calculations, the gas leakage value can be obtained, and the air tightness of the car controller can be detected based on the leakage value.

2. If the car controller is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined that the car controller is leaking air, and the instrument test result will also show NG, which means the air tightness test failed.If the tested new energy vehicle battery does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the air tightness test has passed.

3. Hirays Technology’s breakthrough in air tightness testing in the new energy vehicle industry

Process demonstration of air tightness detector of automobile controller

1. When testing new energy vehicle controllers, the first thing to pay attention to is their safety and non-destructiveness. Since their components are relatively special, the air tightness testing developed by Hirays Technology has the function of non-destructive, efficient, stable and precise testing;

2. This air tightness detector is specially designed for automated customization. It can support multi-channel air tightness testing. Multiple sets of sensors, instruments, tooling and molds are integrated into one, which not only improves the detection efficiency, but also has a professional level of automation.

3. Hirays Technology’s air tightness tester is equipped with the world’s top high-sensitivity sensors and precise pressure control units.In addition, Hiraysi Technology has developed self-developed"IVT"Pneumatic sealing technology has been applied to instruments, greatly improving test accuracy.As the first unit in China to draft corporate standards for waterproof leakage detectors, Hirays Technology's detectors can be calibrated through relevant national calibration centers or metrology testing centers, ensuring the stability and quality of the instruments.
