Case 1: Precise CE & Lifespan Prediction.
For a 100Ah battery:
With an average CE test accuracy of 99.95%, after 500 cycles,CAPk=100*0.9995 500 =77.88Ah
With an average CE test accuracy of 99.955%, after 500 cycles, CAPk= 100*0.99955 500=79.85Ah
The difference is 1.97Ah, meaning the model accuracy differs by 1.97%!
- High-precision CE testing allows for early performance assessment, enabling rapid battery lifespan prediction!
- Lifespan prediction requires accuracy within 0.1% and noise
Case 2: Side Reaction & Material Evaluation.
ΔC or Ch. End Cap measurement requires high-precision charge-discharge equipment. Low accuracy will lead to inaccurate results.
Case 3: Battery Capacity Decay Factor Analysis.
High-precision testers ensure smooth curves and capture small phase change peaks!
Case 4: Leakage Current.
Charge to the target voltage, stabilize under constant voltage, and assess leakage current by the zero-current difference.
Test Plan:
1. Button Cell:
Electrodes: Ternary(фl4mm)vs. Lithium(ф20mm)
Capacity: 2mAh
Equipment: ECT6008-5V10mA
2. Test Process:
Constant current, constant voltage charging: 0.8mA,3.8V, for 72 hours.
High-precision testers ensure accurate leakage current measurement.
