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.
Claims25
(canceled)
An apparatus comprising:
- a battery having an internal impedance;
- a memory to store the internal impedance of the battery;
- and
- a fuel gauge to estimate the internal impedance before or during a time when a load operates in an enhanced power mode and draws a relatively high power from the battery compared to a normal mode.
A system comprising:
- a memory;
- a processor coupled to the memory;
- a wireless interface to allow the processor to communicate with another device;
- and
- a battery to power the processor, wherein the battery includes a fuel gauge to estimate an internal impedance of the battery before or during a time when the processor operates in an enhanced power mode and draws a relatively high power from the battery compared to a normal mode.
A machine-readable media having machine executable instructions that when executed cause one or more machines to perform one or more operations comprising:
- estimate an internal impedance of a battery before or during a time when a processor operates in an enhanced power mode and draws a relatively high power from the battery compared to a normal mode;
- estimate variation of the internal impedance versus a peak power duration;
- and
- cause the processor to operate in view of the estimated variation of the internal impedance.
