AI Technical Summary
Technical Problem
Existing ultrasonic testing methods are difficult to effectively cover and accurately target defective areas in pouch batteries. The separation of defect identification and intervention processes leads to unstable overall intervention results.
Method used
A high-frequency ultrasonic array is used to scan and generate a defect thermal map. Combined with a low-frequency ultrasonic transducer array for synergistic excitation, targeted intervention in the defect area is achieved, forming a closed-loop control for detection and repair.
Benefits of technology
This improved the targeting of defect areas and the efficiency of ultrasonic energy utilization, reduced the risk of damage to the battery structure, and enhanced the safety and effectiveness of defect intervention.
