Product Electric Performance Test
| NO. | Items | Test Conditions | Requirements |
| 1 | Capacity Retention | Fully charging, store them at (20 ± 5)t for 28 days, then discharge to 36.4V @0.2C. | Discharging time^4.25h |
| 2 | Cycle Life @252 |
Discharge to 36V @0.2C, then Charge the battery @0.2C to reach 54.6V. Then charge the battery at constant 54.6V voltage until the charging current decreasing to 0.02C. Rest for 0.5-1 h. discharge to 36.4V@ 0.2C and rest for 0.5-1 h. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity. |
Cycles life ^300 |
| 3 | Storage |
Charge the battery to 40%~65% of its rated capacity using standard charging mode, then keep it in an ± 5*C, humidity 45% ~ 85% room for 12 months, fully charge and discharge it @0.2C until voltage down to 36.4V. (The testing sample should be within 3 months dated from production date) |
Discharge time >210min |
Mechanical Performance
| NO. | content | Testing method | Requirements |
| 1 | Vibration Tes | After standard charging, put battery on the vibration table. 30 min experiment from X, Y, Z axis. Scan rate: 1oct/min; Frequency 10-30Hz, Swing 0.38mm; Frequency 30-55Hz, Swing 0.19mm. | No influence to batteries' electrical performance and appearance. |
