With the rapid development of the automobile industry，Customer requirements for new energy vehicles are also rising.This forces various automobile manufacturers to have constant performance requirements for automobile parts.，especially tocar controllerSealing and waterproofing puts forward higher requirements.car controllerIt is the assembly controller of the electric vehicle power system and has the function of improving the vehicle's power performance, safety performance and economy.

Product to be tested: Automotive controller

In practical applications, the cable intermediate joint of the automobile controller is a very weak link in the entire power transmission system. Due to the influence of the real environment, the cable intermediate joint is likely to be exposed to moisture, water vapor, etc. These conditions will cause accidents such as breakdown and explosion in the intermediate joint, thereby affecting the stable operation of the entire automobile controller.Nowadays, most car controllers are equipped with waterproof measures. Next, Hairis Technology will share with you a case of air tightness and waterproof testing of car controllers.

Equipment used: HairisHCClassic series air tightness testing equipment

Testing plan: Indirect testing method, custom mold according to the structure of the controller, used to seal the controller.After placing the controller into the mold, press the start button on the instrument, and the upper mold of the controller will automatically press down to coincide with the lower mold. After sealing the controller, the instrument enters the test program. According to the set parameters (test pressure15KPA，Inflation time:6S,Stabilization time:8S，Test time:5S, leakage value:0.05KPA) The instrument inflates, stabilizes, and tests the controller, and detects the leakage of the product by monitoring changes in air pressure. The controller system automatically determines the leakage value exceeds the upper limit or fails to reach the test pressure.NG。
