Correction Factor for Pack Voltage. Adjusts
the scaling of the pack voltage measure-
ments. Used to calibrate the measurement
of pack voltage between V
and ground.
Correction Offset for Current. This is the
value the A/D reads when zero current is
flowing through the sense resistor.
Correction Offset Deviation - Offset value
for the auto-zero calibration of the current
readings.
SBData Current[mA] = (I_A/D - CO_CURR
- COD) x CF_CURR / 16384
Calibration: CF_CURR = ((Ammeter[mA] x
16384) - 8192) / (Current - I_A/D at OCV)
Correction Offset for Temperature.
Offset = 0 used for temperature
measurement using internal temperature
sensor.
Correction Offset for Temperature.
Offset = 0 used for temperature
measurement using internal temperature
sensor.
Correction Offset for Cell Voltage. Offset
factor used for individual cell voltage
readings. SBData Voltage[mV] =
(V_A/D - CO_VOLT) x CF_VOLT / 2048
Calibration: New CF_VOLT = Old
CF_VOLT x (Voltmeter[mV] / SBData
Voltage[mV])
Correction Offset for Voltage. Offset factor
used for pack voltage reading.
