High-performance battery cells represent the core of electric vehicle (EV) powertrains regardless of whether they are based on pouch cells, cylindrical cells, or prismatic cells. Since these cells are densely packed in battery assemblies for electric vehicles, the quality and integrity of the battery cells directly affect the road safety of electric vehicles.
Recalls due to defective cells are costly and can significantly impact an automaker's brand reputation. Therefore, it is in the interest of battery suppliers and manufacturers of electric vehicles to test and document to assure the quality of the battery cell.
Cell inspection system for 100% comprehensive inspection
The PouchSTAR cell inspection system offers a complete 360° optical check of cells to ensure a 100% comprehensive inspection. In addition to dimensional monitoring, cell inspection detects surface defects and contamination. Defects are classified, and defective cells are automatically ejected or marked. The system also reliably checks barcodes and data codes and performs fully traceable production documentation.
The ISRA PouchSTAR inspection system can be combined with other ISRA solutions to improve quality assurance and optimize production. The ISRA graphical user interface (GUI) makes it possible to control and monitor multiple production lines. Detection results are displayed in real-time and provide a full picture of the defects found and their causes.
Production analytics software for intelligent correlations
The ISRA production analytics software “EPROMI” creates intelligent correlations. Implementing the gained analysis results can optimize production significantly. Quality assurance techniques also offer improved product safety levels for operators, thereby avoiding future incidents throughout the EV battery assembly process.
