@ -115,28 +115,33 @@ of charge when battery became full/empty". It also could mean "value of
charge when battery considered full/empty at given conditions (temperature,
age)". I.e. these attributes represents real thresholds, not design values.
ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.
CHARGE_COUNTER - the current charge counter (in µAh). This could easily
be negative; there is no empty or full value. It is only useful for
relative, time-based measurements.
PRECHARGE_CURRENT - the maximum charge current during precharge phase
of charge cycle (typically 20% of battery capacity).
CHARGE_TERM_CURRENT - Charge termination current. The charge cycle
terminates when battery voltage is above recharge threshold, and charge
current is below this setting (typically 10% of battery capacity).
CONSTANT_CHARGE_CURRENT - constant charge current programmed by charger.
CONSTANT_CHARGE_CURRENT_MAX - maximum charge current supported by the
power supply object.
INPUT_CURRENT_LIMIT - input current limit programmed by charger. Indicates
the current drawn from a charging source.
CHARGE_TERM_CURRENT - Charge termination current used to detect the end of charge
condition.
CALIBRATE - battery or coulomb counter calibration status
CONSTANT_CHARGE_VOLTAGE - constant charge voltage programmed by charger.
CONSTANT_CHARGE_VOLTAGE_MAX - maximum charge voltage supported by the
power supply object.
INPUT_CURRENT_LIMIT - input current limit programmed by charger. Indicates
the current drawn from a charging source.
CHARGE_CONTROL_LIMIT - current charge control limit setting
CHARGE_CONTROL_LIMIT_MAX - maximum charge control limit setting
ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.
CALIBRATE - battery or coulomb counter calibration status
CAPACITY - capacity in percents.
CAPACITY_ALERT_MIN - minimum capacity alert value in percents.
