Abstract
An apparatus is provided which comprises: a first circuitry to estimate variation of an internal impedance of a battery; a second circuitry to estimate a high power that the battery can supply for a first time-period, based on the estimated variation of the impedance of the battery; and a third circuitry to facilitate operation of one or more components of the apparatus in accordance with the estimated high power for the first time-period.

An apparatus comprising:
- a first circuitry to estimate variation of an internal impedance of a battery;
- a second circuitry to estimate a high power that the battery can supply for a first time-period, based on the estimated variation of the impedance of the battery;
- and
- a third circuitry to facilitate an operation of one or more components of the apparatus in accordance with the estimated high power for the first time-period.
A system comprising:
- a memory to store instructions;
- a processor coupled to the memory;
- a battery to supply power to the memory and the processor;
- a first circuitry to estimate temporal variation of an internal impedance of the battery;
- and
- a second circuitry to estimate a temporal variation of available peak power from the battery, based on the estimated temporal variation of the impedance of the battery,
- wherein the processor is to operate in an enhanced mode, based on the estimated temporal variation of the available peak power from the battery.
Non-transitory computer-readable storage media to store instructions that, when executed by a processor, cause the processor to:
- estimate variation of an impedance of a battery with time;
- estimate a first power that the battery can supply for a first time-period, based on the estimated variation of the impedance of the battery with time;
- and
- facilitate operation of one or more components in accordance with the estimated first power for the first time-period.
