4.3 Voltage Range
The measured cell voltage is segmented into several voltage ranges. The charging algorithm adjusts
ChargingCurrent() according to the temperature range and voltage range. The voltage ranges set in data flash
should adhere to the following format:
Charging Voltage Low ≤ Charging Voltage Med ≤ Charging Voltage High ≤ × Temp Charging:Voltage
where x is Standard or Rec. Depending on the specific charging profile, the Low Temp Charging:Voltage and
High Temp Charging:Voltage settings do not necessarily have the highest setting values.
