Bagaimana organisasi seharusnya mengevaluasi kualitas sel LiFePO4 280Ah selama pengadaan?

Untuk memastikan sel 280Ah LiFePO4 berkualitas tinggi, organisasi harus fokus pada indikator yang dapat diukur dan diverifikasi selama pengadaan:Jejak dan Kepatuhan: Verifikasi kode serial/QR unik terhadap basis data produsen. Cari laporan uji transportasi UN38.3, sertifikasi IEC 62619, dan kepatuhan tingkat sistem dengan UL 1973/9540 jika berlaku.Metrik Kinerja: Uji sel untuk kapasitas (≥100% dari kapasitas terukur pada pelepasan 0.5C), DC...

How can businesses evaluate the quality of 3.7V 1500mAh lithium-ion cells for procurement?

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...

What does the label ‘3.7V 1500mAh rechargeable’ on a lithium-ion battery cell signify?

The label '3.7V 1500mAh rechargeable' on a lithium-ion battery cell indicates its nominal voltage and rated capacity. Specifically:Nominal Voltage (~3.6–3.7V): This is the average voltage during discharge under standard conditions. Most 3.7V cells charge to a maximum of 4.2V and should not be discharged below 2.5–3.0V for safety and longevity.Rated Capacity (1500mAh): This represents the...
