expertise for lithium-ion battery testing
Testing is an essential step when producing high-quality lithium-ion batteries. There are several inline and end-of-line tests, depending on your requirements.
visual tests
electric tests
leakage tests
visual tests
Component position:
- Checking of the positional tolerances of various components after assembly
- Exact position determination – tolerance compensation increases precision, especially for large components with large tolerances (e.g., battery pack)
Inspection of applied adhesive foils (shape from shading)
Component identification: reading barcodes, data matrix codes, etc. and entering them into a database
Surface inspection
Contour control: geometric inspection of contours, position recognition
electric tests
- OCV, ACIR, DCIR, EIS
- Isolation tests: cell to cell, cell/stack to housing
- High-voltage resistance tests
- Functional tests: CAN bus test, pulse power test with discharge to grid
leakage tests
Check the tightness of the module/pack housing or of the cooling circuit by
- Pressure test
- Sniffing test
