Abstract
A method is disclosed for providing information related to the power capacity of a rechargeable battery at a specified time, wherein the battery is disposed to supply power to a laptop computer or other electronic device. The method comprises the step of acquiring a set of cumulative data that represents the capacity of the battery at different times when the battery is being used to supply power to the device. The method further comprises selectively processing the set of data, to provide an estimate of the battery time that is available at the specified time. The estimate is then used to determine whether or not the battery has sufficient power capacity to complete a particular task subsequent to the specified time.
Claims20
A method for providing information relating to the power capacity of a rechargeable battery at a specified time, wherein the battery is disposed to supply power to an electronic device, the method comprising the steps of:
- acquiring a set of cumulative data that represents the capacity of said battery at different times, when said battery is being used to supply power to said device;
- selectively processing said set of cumulative data to provide an estimate of the battery time that is available at said specified time;
- and
- using said estimate to determine whether said battery has sufficient power capacity to complete a particular task subsequent to said specified time.
A computer program product in a computer readable medium for providing information relating to the power capacity of a rechargeable battery at a specified time, wherein the battery is disposed to supply power to an electronic device, the computer program product comprising:
- first instructions for acquiring a set of cumulative data that represents the capacity of said battery at different times, when said battery is being used to supply power to said device;
- second instructions for selectively processing said set of cumulative data to provide an estimate of the battery time that is available at said specified time;
- and
- third instructions for using said estimate to determine whether said battery has sufficient power capacity to complete a particular task subsequent to said specified time.
An apparatus for providing information relating to the power capacity of a rechargeable battery at a specified time, wherein the battery is disposed to supply power to an electronic device, the apparatus comprising:
- a first component for acquiring a set of cumulative data that represents the capacity of said battery at different times, when said battery is being used to supply power to said device;
- a second component for selectively processing said set of cumulative data to provide an estimate of the battery time that is available at said specified time;
- and
- a third component for using said estimate to determine whether said battery has sufficient power capacity to complete a particular task subsequent to said specified time.
