No. Item Parameters Test Method and Condition
1 Capacity ≥26.0Ah The cell performs standard charge and discharge,calculate the discharge capacity.
2 AC impedance 0.8 ± 0.15 mΩ AC impedance of the cell is measured at 1KHz at 30%SOC.
3 Rate Discharge 1.0C ≥ 100%
2.0C ≥ 99%
3.0C ≥ 95%
After standard charging,discharge capacity is measured with the various currents at the cut off voltage of 2.7V
4 Discharge at high & low temperature 45,55℃≥95%;
25℃≥100%;
10℃≥95%;
0℃≥90%;
-10℃≥85%;
-20℃≥80%;
-30℃≥70%
After standard charging,the cell is stored in different temperature (25℃,-20℃,0℃,10℃, 45℃,55℃) for 2 hours, then test the cell
capacity separately in each temperature with standard discharge method. (-10, 0℃ cut off at 2.5V, -20,-30℃ cut off at 2.2V).
5 Cycle Life 25℃,
Remaining capacity≥80%
The cell performs charge and discharge cycle at 1C current for 3000 times, and between charge and discharge the cell should rest at least 10 min, then test the remaining capacity.
6 Storage at 25℃
100%SOC
Capacity recovery ≥98% After standard charging,the cell stored at 25℃ for 30 days, then measured the remaining and recovery capacity by standard discharge method.
7 50%SOC
Storage at 45℃
Remaining capacity≥95%;
Capacity recovery ≥98%
After standard charging to 50%SOC, the cell stored at 45 ℃ for 30 days, then the cell stored at 25℃for 4h, measured the remaining capacity and capacity recovery by standard discharge method.
