This fixture requires a dry room environment to prevent signal contamination and must have all digital connection channels properly insulated during testing. The pressure sensor data lines must be shielded from electrical noise to maintain measurement fidelity.
- Dry Room Requirement: Operate the fixture exclusively within a dry room testing environment to avoid external signal contamination during long-term thermal validation loops.
- Electrical Insulation: Insulate all digital connection channels to prevent pressure sensor data interference and maintain signal integrity.
- Pressure Monitoring Integrity: Monitor pressure sensor data carefully to avoid noise from electrical sources and ensure consistent force readings.
- Material Compatibility: Select fixture material based on electrolyte resistance and load capacity to avoid corrosion, swelling, or mechanical failure.
- Cell Dimensional Constraint: Maximum cell length and width is fixture plate dimensions minus 30 mm, with cell thickness up to 2.5 cm using standard vertical spacing.
Position the pouch cell between the four parallel plates, ensuring alignment with the central single nut mechanism. Tighten the nut to apply uniform pressure, then connect the pressure sensor data cable to the monitoring system.
Required Equipment: 4-layer stainless steel fixture with single nut locking, Pressure sensor with data acquisition cable, Dry room facility
- Inspect and Prepare
Inspect the four-layer fixture plates for cleanliness and verify that the pressure sensor cable is properly connected. - Position the Cell
Position the pouch cell centrally between the second and third plates, ensuring the cell tabs remain accessible. - Apply Clamping Force
Tighten the single central nut gradually to apply clamping force, monitoring the pressure sensor to achieve the desired load. - Verify Alignment
Verify that the fixture plates remain parallel and that pressure distribution is uniform across the cell surface. - Connect Monitoring System
Connect the pressure sensor data line to the external monitoring system and ensure all digital connections are properly insulated. - Condition the Assembly
Place the assembled fixture in a dry room environment and allow temperature stabilization before starting cycle testing.
What are the trade-offs between the standard 400 kg working pressure and the customizable 600 kg high-pressure profile for the ATM-PCBT-SS304-4L fixture?
The standard working pressure is 400 kg, customizable up to 600 kg for reinforced testing. Higher pressure requires thicker plates (e.g., 12 mm plates for 120×160 mm and 150×180 mm sizes) to maintain rigid mechanical force retention, increasing overall fixture weight. Cell thickness support (0.1 mm to 2.5 cm) and four-layer vertical spacing remain adjustable independently of pressure level, as both dimensions and pressure can be fully customized per cell size and test requirements.
How is the maximum pouch cell length and width determined for a given plate size of the ATM-PCBT-SS304-4L?
The maximum compatible cell length and width equals the fixture plate dimensions minus 30 mm, as explicitly stated in the dimensional calculation rule. For example, the 120×160 mm fixture accommodates cells up to 90×130 mm. The standard cell thickness range is 0.1 mm to 2.5 cm, with adjustable four-layer vertical spacing available upon request, ensuring broad compatibility with single pouch cells.
What environmental and operational measures are required to prevent pressure sensor data interference in the ATM-PCBT-SS304-4L during long-term cycle testing?
To maintain pressure sensor data integrity, all digital connection channels must be properly insulated and the fixture must be operated within a dry room testing environment to avoid external signal contamination, as specified in the operational notice. The built-in pressure sensor with real-time acquisition cable requires careful monitoring to prevent signal line distortion, especially before long-term thermal validation loops.
The ATM-PCBT-SS304-4L is a 4-layer 304 stainless steel pouch cell test fixture with a single-nut clamping mechanism, offering uniform pressure distribution and real-time pressure monitoring for cycle testing of single pouch cells up to 600 kg load.
Positive
- Uniform single-nut pressure distribution: The single-nut locking design ensures balanced parallel load transfer across the cell surface, preventing stress localization and improving test reproducibility.
- Real-time pressure monitoring integration: Built-in pressure sensor with data acquisition cable enables continuous external pressure tracking without electrical noise interference during high-load cycles.
Trade-offs
- Requires dry room operation: The fixture must be used in dry room environments to prevent external signal contamination and pressure sensor data interference during long-term thermal validation loops.
- Cell size limited by fixture dimensions: Maximum compatible cell length and width are 30 mm less than fixture dimensions, requiring careful sizing selection to avoid overhang or misalignment.
