CGN Dasheng NDT Helps Power Batteries Pass Quality Tests Smoothly
News of new energy vehicle fires occasionally surfaces, and the culprit is almost always the power battery. To fundamentally address this industry-wide problem, the mandatory national safety standard "Safety Requirements for Traction Battery of Electric Vehicles" will officially take effect on July 1, 2026, ushering in the strictest examination the battery industry has ever faced. Facing high-standard testing requirements, CGN Dasheng has deployed its full suite of non-destructive testing capabilities, leveraging precise and comprehensive non-destructive flaw detection technologies to help the industry deliver a high-standard safety answer sheet. The internal structure of a power battery is wound layer upon layer, resembling a Swiss roll. During production, subtle defects such as electrode foil wrinkles, metal debris contamination, and misalignment between positive and negative electrodes may occur. These "minor issues" can evolve into overheating,...
