12.2.1 CC Gain/Capacity Gain Calibration
- Apply a known current (typically 1 A to 2 A), and ensure ICC is flowing through the sense resistor connected between the SRP and SRN pins.
- If ManufacturingStatus()[CAL_EN] = 0, send 0x002D to AltManufacturerAccess() to enable the [CAL_EN] flag.
- Send 0xF081 to AltManufacturerAccess() to enable raw CC output on MACData().
- Poll MACData() until ZZ increments by 2 before reading data.
- Check the ADC conversion current output from MACData():
- ADCCC = AAaa of MACData()
Is ADCCC < 0x8000? If yes, use ADCCC; otherwise, ADCCC = –(0xFFFF – AAaa + 0x0001).
- ADCCC = AAaa of MACData()
- Average several readings for higher accuracy. Poll MACData() until ZZ increments to indicate that updated values are available:
- ADCCC = [ADCCC(reading n) + … + ADCCC(reading 1)]/n
- Calculate gain values:
- Write the new CC Gain and Capacity Gain values to data flash.
- Recheck the current reading. If the reading is not accurate, repeat the steps.
- Send 0x002D to AltManufacturerAccess() to clear the [CAL_EN] flag if all calibration is complete.
