Regarding air tightness testing in the new energy vehicle industry, we have covered it in several cases we shared before. Whether it is new energy vehicle charging guns, car controllers, car wiring harnesses, and new energy vehicle power packs, these products require special air tightness treatment.The national dustproof and waterproof requirements generally require the protection level to reach IP67 or IP68. Therefore, in order to ensure the safety of people using new energy vehicles, every special component must undergo air tightness testing.

Hirays Technology has also conducted in-depth research on air tightness testing in the new energy automobile industry and has achieved good results. This time we will analyze past cases and air tightness testing in the automotive industry, hoping to be helpful to everyone.

1. Air tightness testing analysis in the new energy automobile industry

1. For the new energy vehicle industry, whether it is internal components or related auxiliary products, only good air tightness can fully drive the use of new energy vehicles.

2. During the air tightness test, it is necessary to conduct corresponding tests under different working conditions of new energy vehicles. For different working conditions of new energy vehicles, when selecting the corresponding test, attention must be paid to the calculation method, pressure, and software algorithm calculations to accurately determine whether there are defects in the batteries in the new energy system and improve the production quality of new energy vehicles.

3. Nowadays, there are various air tightness testing methods for this industry, and different products have a set of applicable methods, but in summary, it is to judge whether their air tightness is qualified by judging their leakage value and air pressure condition; air tightness testing in the new energy automobile industry and the development of the new energy automobile industry complement each other and develop together, and only good equipment can develop in the long term.

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

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

2. Hirays Technology’s air tightness testing is more flexible and adaptable. When conducting air tightness testing in the new energy automobile industry, it can connect different tooling molds to perform multi-channel simultaneous testing or adaptability testing. Whether it is direct testing or indirect testing, the results are accurate and the testing efficiency is high;

3. Hirays Technology’s air tightness tester is equipped with the world’s top high-sensitivity sensors and a precision pressure control unit from American Fairchild.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.

4. The Hirays air tightness detector has a high degree of automation, short detection time, and a simpler operation interface.The tester is also equipped with"positive, negative&"Two pressure forms and 8 basic test modes, which can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, diversified self-service operations, and combines artificial intelligence with intelligence to enhance the operability of the device.
