Electrical Characteristics Tests
Item | Specifications | Notes |
---|---|---|
Full Charge | The battery is charged at a 1.675A constant current until thevoltage reaches 4.20V. The current is then reduced to keep aconstant voltage of 4.20V. The total charging time is 4.0 hoursat 25°℃. | |
Capacity | (1) Within 1 hour after fully charging at 25°C as per item 6.1,the battery is discharged at 0.67A continuously to 2.5V at25°C. (2)Within 1 hour after fully charging at 25°C as per item 6.1,the battery is discharged at 3.35A continuously to 2.5V at25°C. |
≥ 300min. ≥ 54min. |
Cycle Life | After the battery has been subjected to 300 repeated chargeand discharge cycles (charged by CC-CV of 1.675A-4.20V for4.0 hours; discharged by CC of 3.35A to 2.5V at25°C), thedischarge time is measured as per ltem 6.2, (2). | ≥ 38min. |
Temperature Characteristics | (1)Within 1 hour after fully charging at 25°℃ as per item 6.1,the battery is stored at 0°℃ for 3 hours. The discharge timeis then measured as per Item 6.2, (2) at 0°℃. 2) Within 1 hour after fully charging at 25°C as per item 6.1,the battery is stored at 60℃ for 3 hours. The dischargetime is then measured as per Item 6.2,(2) at 60°℃. |
≥ 30min. ≥ 50min. |
Storage at Fully Charged State | After fully charging at 25°C per item 6.1, the battery is storedfor 20 days at 60°℃ After storage, the battery is held at 25°℃for 3 hours. Then, the discharge time is measured as per Item6.2,(2). Then, the same battery is fully charged again and dischargeda second time and measured as per ltem 6.2,(2) at 25°C. |
≥ 30min. ≥ 40min |
Storage at Fully Discharged State | After fully charging at 25°C, the battery is discharged as perltem 6.2, (2). Then,the battery is stored for 20 days at 60°C.After storage, the battery is held at 25℃C for 3 hours. Then, thedischarge time is measured as per ltem 6.2,(2) at 25°℃. | ≥ 50min |
Drop | After fully charging at 25℃,the cell is dropped 3 times in random directions from a height og 1M onto a flat surface of concrete. | No rupture, no fire |
