Power battery defect inspection

Batteries are the core components of electric automobile, and the safety of batteries directly affects the driving safety of the vehicles. By inspecting the welding process defects of electric automobile batteries, such as the presence of weld points, pinhole welding pits leading to unreliable weld points, etc., it is possible to detect potential safety hazards in the batteries. This ensures that the vehicle will not experience safety incidents during operation due to battery issues.
