Standard Charge | Charging the Battery initially with constant current at 0.5C and then with constant voltage at 58.4V till charge current declines to 0.05C. | |
Rated Capacity | The capacity means the discharge capacity of the Battery, which is measured with discharge current of 0.5CA with 41.6V cut-off voltage after the standard charge. | |
Discharge Performance | When connecting with load, the battery can supply power. Charge the battery with standard charge mode, then rest for 0.2h, then discharge with 0.2C until the voltage is 41.6V. | |
Cycle Life | Test condition Charge: 0.2C to 58.4V Discharge: 0.2C to 41.6V 80% or more of 1st cycle capacity at 0.2C discharge of Operation | |
Self-discharge | After the standard charging, storied the Batteries under the condition for 30days, then measured the capacity with 0.5C till 41.6V | |
Initial Impedance | Internal resistance measured at AC 1KHz after 50% charge |
