Electrical
- Standard Charge: Charging the cell initially with constant current at 1C and then with constant voltage at 58.4V (accuracy +(or minus) 0.05V) until charging current declines 1C at 77-86 F(25-30C)
- Standard Discharge: Discharging the cell with constant current at 1C till cut-off voltage at 36.8V. Temperature: 77-86 F (25-30C)
- Initial Internal Impedance: This means AC impedance of the pack measured at 1KHz after half full charged. Initial Internal Impedance < (or equal)10(ohm)
- Initial Capacity: The capacity means the discharge capacity of the battery, which is measured with discharge current of 1C with 36.8V cut-off voltage after the standard charge.
- Initial Capacity: @95% normal capacity. Temperature: 7 -86 F(25-30 C).
