Recoverable capacity | Constant current 0.2C charge to 58.4V, then constant voltage 58.4Vcharge to current declines to 0.01C, rest for 10min,constant current 0.2C discharge to 43.2V,rest for 10min.Repeat above steps 3 times, recording the maximum capacity | ||
Cycle Performance | Under the temperature of 23±20C,charge the battery with 0.2C, when the voltage reaches up to 58.4V charge with constant voltage until the charge current ≤0.02C,then stop charging, then rest for 0.5h, then discharge with 0.2C to 43.2V. Cycle with the above mode, when the continuous discharge time <3H stop cycling. The cycle life is required ≥6000 times. | ||
Storage Humidity | ≤75% RH | ||
Appearance | Without distortion and leakage | ||
Standard testing condition | Temperature: 25±2oC Humidity :≤75%RH Atmospheric Pressure:86-106 Kpa |
