Secondary Cells Testing TRIZ Cases

Two-stage X-ray and tomographic inspection checks single cells and stacked groups to improve alignment detection, impurity screening, and throughput.

Dual movable mechanisms align charge-discharge contactors to battery thickness variation, maintaining reliable terminal contact without larger trays.

A reciprocating two-part stage keeps battery cells moving through inspection while new cells are loaded, cutting sequential inspection delays.

Eddy current sensing automates battery lead weld inspection, improving depth-based accuracy and consistency without destructive testing.

Mechanical excitation reveals voltage spikes from torn or separated battery current collector foils without opening the cell.

Measures electrode-separator adhesion while immersed in electrolyte, avoiding dry-state error and volatilization during battery-condition testing.

Dual-energy X-ray inspection reveals metal particle dispersion in thermally conductive battery resin without costly CT or disassembly.

A segmented jig and through-hole layout keep pouch cells in shape during shock testing while enabling protected, accurate temperature measurement.

Peripheral sensing modules and computed row-column expansion sums identify defective batteries while cutting sensor count, cost, and pack space use.

Induced-current sensing scans pouch battery cells for cracks, shorts, and weld defects with better tolerance to distance and position errors.

Low-voltage AC reflectometry with trained models locates battery pack continuity defects while reducing test weight, cost, and safety risk.
