turns 10% and RelativeStateOfCharge() returns 50%,
the Relative StateOfCharge() is more likely between 50
and 60%. The bq2060 sets MaxError() to 100% on a full
reset. The bq2060 sets MaxError() to 2% on completion
of a learning cycle, unless the bq2060 limits the learning
cycle to the +512/-256mAh maximum adjustment val-
ues. If the learning cycle is limited, the bq2060 sets
MaxError() to 8% unless MaxError() was already below
8%. In this case MaxError() does not change. The
bq2060 increments MaxError() by 1% after four incre-
ments ofCycleCount()without a learning cycle.
If voltage-based corrections are applied to the coulomb
counter, MaxError() is set to 25%.
Purpose:
The MaxError() function has real value in two ways:
first, to give the user a confidence level about the state
of charge and second, to give the power management
system information about how aggressive it should be,
particularly as the battery nears the end ofits life.

Unsigned integer—percent uncertainty for selected
information.

RelativeStateOfCharge() (0x0d); [0x0d]
Description:
Returns the predicted remaining battery capacity ex-
pressed as a percentage ofFullChargeCapacity() (%).
Purpose:
The RelativeStateOfCharge() function is used to esti-
mate the amount of charge remaining in the battery rel-
ative to the last learned capacity.

Output:
Unsigned integer—percent ofremaining capacity.
Units: %
Range: 0 to100%
Granularity: 1%
Accuracy: -0,+MaxError()
AbsoluteStateOfCharge()(0x0e); [0x0e]
Description:
Returns the predicted remaining battery capacity ex-
pressed as a percentage of DesignCapacity() (%). Note
that AbsoluteStateOfCharge() can return values greater
than 100%.
Purpose:
The AbsoluteStateOfCharge() function is used to esti-
mate the amount of charge remaining in the battery rel-
ative to the nominal or DesignCapacity().
SMBus Protocol:

Output:
Unsigned integer—percent ofremaining capacity.
Units: %
Range: 0 to100+%
Granularity: 1%
Accuracy: -0,+MaxError()
RemainingCapacity() (0x0f); [0x0f]
Description:
Returns the predicted charge or energy remaining in the
battery. The RemainingCapacity() value is expressed in
either charge (mAh at a C/5 discharge rate) or energy
(10mWh at a P/5 discharge rate) depending on the set-
ting ofthe BatteryMode()’s CAPACITY_MODEbit.
Purpose:
The RemainingCapacity() function returns the battery’s
remaining capacity. This information is a numeric indica-
tion of remaining charge or energy given by the Absolute
or Relative StateOfCharge() functions and may be in a
better formforuse bypowermanagement systems.
SMBus Protocol:
Read Word
Output:
Unsigned integer—remaining charge in mAh or
10mWh.
