Abstract
An electronic tool and method to manage a battery includes a processor to monitor a battery charge and estimate a required charge needed by the electronic tool to complete any task or job shift. When the processor determines the battery charge is insufficient, the processor applies business rules to reduce and terminate functions of the electronic tool to conserve power.
Claims37
A method, comprising:
- determining an actual charge for a battery of an electronic device to be powered by the battery;
- estimating a power consumption requirement for a task to be performed by the electronic device based on a weighted average of a plurality of historical data points regarding actual power consumption of the electronic device for completing the task, wherein a weight factor assigned to each of the historical data points is inversely correlated to an age of the historical data point;
- determining whether the actual charge for the battery is sufficient for the estimated power consumption;
- and
- if it is determined that the actual charge for the battery is not sufficient, providing a warning of insufficient battery charge.

A method comprising:
- estimating power needed by an electronic device powered by a battery to complete a task based on a weighted average of a plurality of historical data points regarding actual power consumption of the electronic device for completing the task, wherein a weight factor assigned to each of the historical data points is inversely correlated to an age of the historical data point;
- determining charge remaining in the battery of the electronic device;
- determining whether sufficient charge remains in the battery based, at least in part, on the estimated power needed;
- and
- reducing the power requirements of the electronic device in response to a determination that the battery does not have sufficient charge for the electronic device to complete the task.

An electronic device capable of managing power requirements and monitoring a battery status, the device comprising:
- a battery;
- a processor that monitors a battery charge and estimates a required charge needed by the electronic device to be powered by the battery to complete a task based on a weighted average of a plurality of historical data points regarding actual power consumption of the electronic device for completing the task, wherein a weight factor assigned to each of the historical data points is inversely correlated to an age of the historical data point;
- and
- the processor further determines whether the battery has sufficient charge to complete the task, wherein the processor reduces functions provided by the electronic device to conserve power in response to the determination that the battery does not have sufficient charge for the electronic device to complete the task.
