Product Electric Performance Test
|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|
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|
|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.|
|2||Drop Test||Random drop the battery from 1.0m height onto wood board 2 times.||No explosion or fire|
