Abstract
A method includes: receiving a temperature indication, the temperature indication being a function of a temperature of a power pack of a portable electronic device; determining, as a function of the temperature indication, whether the temperature is within an elevated operating temperature range; and reducing a charge termination voltage and a charging current when the temperature is within the elevated operating temperature range.
Claims15
A method comprising:
- receiving a temperature indication, the temperature indication being a function of a temperature of a power pack of a portable electronic device;
- determining, as a function of the temperature indication, whether the temperature is within an elevated operating temperature range;
- and
- when the temperature is within the elevated operating temperature range, reducing a charge termination voltage and a charging current supplied to reach the charge termination voltage, and increasing a termination current.
A portable electronic device comprising:
- a processor, the processor electrically coupled to a temperature sensor coupled to a power pack;
- a power pack electrically coupled to the processor;
- wherein the processor
- receives a temperature indication from the temperature sensor, the temperature indication being a function of a temperature of the power pack;
- determines, as a function of the temperature indication, whether the temperature is within an elevated operating temperature range;
- and
- when the temperature is within the elevated operating temperature range, controls a power management subsystem to reduce a charge termination voltage and a charging current supplied to reach the charge termination voltage, and increase a termination current.
A computer-readable medium having computer readable instructions stored thereon for execution by a processor to:
- receive a temperature indication, the temperature indication being a function of a temperature of a power pack;
- determine, as a function of the temperature indication, whether if the temperature is within an elevated operating temperature range;
- and
- when the temperature is within the elevated operating temperature range, reduce a charge termination voltage and a charging current supplied to reach the charge termination voltage, and increase a termination current.
