Are EV batteries quality inspected?

(Image: Volume Graphics; scan: Waygate Technologies) Computed tomography data analysis and visualization provide intelligent quality assurance for EV batteries. Because of their power density, lithium-ion batteries as used by electric vehicles (EV) are subject to strict quality monitoring.

What information should be included in a flow battery report?

c description of the electrolyte (s), the overall dimensions of the individual stack as well as the electrical rating in capacity and nominal voltage of the cell stack. The report will also include information on the complete flow battery system including the manufacturer's name and model number of the system, the

What challenges do quality engineers face when examining batteries using CT?

When examining batteries using CT, quality engineers face a challenge: The interesting structures in the gray-scale images provided by the CT scanner often have very low contrasts. This is due to the low-density differences of some materials. In addition, the films and coatings of the cell packages are very thin and close together.

What is a detachment in a EV battery?

Delaminations, the detachment of the electrode windings or coatings, can be easily visualized with CT. (Image: Volume Graphics; scan: Waygate Technologies) Computed tomography data analysis and visualization provide intelligent quality assurance for EV batteries.
