5-4-7 Smart Battery Data See Appendix B.

5-5. Self Capacity Calibration

FullChargeCapacity(FCC) is the Discharge Capacity of the battery measured at the end.

On initialization(application of Vcc or Reset) FCC is set to the default value such as the Design Capacity.

The FCC is susceptible to error on initialization or if no updates occur. On initialization, the FCC

value includes the error between the design capacity and the actual capacity. This error is present until

a qualified discharge occurs and FCC is updated. The other cause of FCC error is battery wear-out.

As the battery ages, the measured capacity must be adjusted to account for changes in actual battery

capacity.

Periodic qualified discharges from full to empty will minimize errors in FCC.

5-6. Calibration Method

Stpe 1 : Full Charge

For Li-Ion charge control, charging Voltage must be set to the pack voltage desired during the

constant-voltage phase of charging.

The bq2060 detects a current taper termination when the pack voltage is greater than the voltage

determined by Current Taper Qual Voltage in E/R and the charging current is below a threshold

determined by Current Taper Threshold in E/R, for at least 40 s.

Valid charge will not have any errors such as

An over-voltage fault exists when the voltage is more than the overvoltage margin above

the charging voltage

Over current fault exists when the charge current is more than the overcurrent margin above

the charging current

Over-temperature fault exists when the Temperature is greater than or equal to the Max T

value in E/R

Under-temperature faults exists when the Temperature is lower than 0 deg.C




Step 2 : Full DisCharge

Discharged to 3.0V/Cell without error. Discharging Current should be less than 0.2C

No valid charge(charges greater than 10 mAh) initiations during the discharge process

The self-discharge is not more than 256 mAh.

No Low or High temperature state

5-7. LED Display

Pressing the LED button, activates the LED display for 4 seconds. Each LED output represents the
