Hoe kunnen bedrijven de kwaliteit van 3,7V 1500mAh lithium‑ioncellen beoordelen bij inkoop?

Businesses should adopt a structured evaluation framework:Performance Metrics: Test capacity at 0.2C and actual load profiles (≥98% of rating at 25°C). Measure internal resistance (DCIR) to assess heat generation and pulse performance. Validate cycle life (e.g., 80% capacity retention after 300–1,200 cycles at defined DoD).Safety & Compliance: Require certifications like UN38.3 (transport), IEC 62133-2 (portable...

Hoe moet men de kwaliteit van binnenkomende LiFePO4 prismatische accucellen testen?

To ensure quality, follow this acceptance protocol for incoming cells:Visual Inspection: Check for bulging, dents, or seal contamination. Lay a straightedge on the can to detect warping.Weight Measurement: Use a calibrated scale to identify outliers in the batch.QR Code Scanning: Log batch, serial numbers, and open-circuit voltage (OCV) to verify traceability.Electrical Checks: Measure OCV after...
