Change Control
Charging Voltage
The 16-bit value,
Charging Voltage
DF 0x390x3a programs the ChargingVoltage( ) value broadcast to a smart
charger. It ialso sets the base value for determining overvoltage conditions during charging and voltage
compliance during a constant-voltage charging methodology. It is stored in mV.
Over Voltage
The 16-bit value,
Over Voltage Margin
DF 0x5a0x5b, sets the limit over ChargingVoltage( ) in mV that is to be
considered as an overvoltage charge-suspension condition.
Charging Current
ChargingCurrent( ) values are either broadcast to a Level 2 smart battery charger or read from the bq2083V1P2
by a Level 3 smart battery charger. The bq2083V1P2 sets the value of ChargingCurrent( ), depending on the
charge requirements and charge conditions of the pack.
When fast charge is allowed, the bq2083V1P2 sets ChargingCurrent( ) to the rate programmed in
Fast-Charging
Current
DF 0x3d0x3e.
Fast-Charging Current
is stored in mA.
When fast charge terminates, the bq2083V1P2 sets ChargingCurrent( ) to zero and then to the
Maintenance
Charging Current
DF 0x3f, 0x40 when the termination condition ceases. The desired maintenance current is
stored in mA.
When Voltage( ) is less than EDV0, the bq2083V1P2 sets ChargingCurrent( ) to
Precharge Current
DF 0x41,
0x42. Typically this rate is larger than the maintenance rate to charge a deeply depleted pack up to the point where
it may be fast charged. The desired precharge rate is stored in mA.
If temperature is between 0
°
and the precharge threshold PC (
°
C), the bq2083V1P2 sets ChargingCurrent( ) to
PreCharge Current.
The threshold is programmed in the
Precharge Temp
DF 0x43.
Precharge Temp
PC (
°
C)
0.1
The bq2083V1P2 also sets ChargingCurrent( ) to the precharge rate if Voltage( ) is less than the value
programmed in
Precharge Voltage
DF 0x3b0x3c.
Precharge Voltage
is programmed in mV.
Charge Suspension
During charge, the bq2083V1P2 compares the current to the ChargingCurrent( ) plus the value in
OverCurrent
Margin
DF 0x5c0x5d. If the pack is charged at a current above or equal to the ChargingCurrent( ) plus the
programmed value, the bq2083V1P2 sets ChargingCurrent( ) to zero to stop charging.
The desired
Overcurrent Margin
is programmed in mA.
The desired temperature threshold for charge suspension, MAXTEMP (
°
C), is programmed in
Max Temperature
DF 0x53, 0x54 and is stored as shown:
Max Temperature
MAXTEMP
0.1
The bq2083V1P2 clears the maximum temperature condition when Temperature( ) drops by the amount
programmed in
Temperature Hysteresis
DF 0x55 from MAXTEMP or when the temperature is less than or equal
to 43.0
°
C.
Temperature Hysteresis
is stored in
°
C.
The bq2083V1P2 suspends fast charge when fast charge continues past full by the amount programmed in
Maximum Overcharge
DF 0x4e-0x4f.
Maximum Overcharge
is programmed in mAh.
FULLY_CHARGED Bit Clear Threshold
The bq2083V1P2 clears the FULLY_CHARGED bit in BatteryStatus( ) when RelativeStateOfCharge( ) reaches
the value,
Fully Charged Clear %
DF 0x47.
Fully Charged Clear %
is an 8-bit value and is stored in percent.
