4. Important Notes

 

Size Rule: Cell length & width = Fixture length & width − 30 mm; Three-layer spacing can be adjusted according to cell thickness, providing safe clamping space and uniform pressure to ensure stable battery cycle test data.

 

The sainless steel three-layer fixture is upgraded from the two-layer fixture. The core upgrade is the addition of a pressure sensing layer, where the pressure sensor is an essential structural component. The sensor data cable can be connected to external acquisition equipment to realize real-time monitoring of test pressure. Compared with the basic version, it also has stronger rigidity, excellent load-bearing performance and higher stability. The three-layer synchronous clamping ensures uniform pressure distribution, non-magnetic, and no interference with test data.

 

Fixture size, three-layer spacing, material and pressure level can be customized according to different battery cycle test requirements; 316 stainless steel is recommended for leakage/immersion testing scenarios.
