Abstract

A method for managing a battery to perform a final action, the method includes determining a battery supplying power to an electronic device is discharging and receiving battery specification information for the battery. The method includes receiving environmental condition information for the battery and determining an open circuit voltage for the battery. The method includes determining a base capacity for the battery, a first capacity reduction for the battery based on the battery specification, and a second capacity reduction for the battery based on the environmental condition information. The method includes determining an overall expected capacity for the battery based on the first capacity reduction and the second capacity reduction, where the overall expected capacity represents available energy. Responsive to determining the available energy for the battery is less than a required energy to perform an action prior to battery depletion, the method includes sending a warning notification.

First claim

What is claimed is:

1. A computer-implemented method comprising:
determining a battery supplying power to an electronic device associated with a user is discharging;
receiving battery specification information for the battery;
receiving environmental condition information for the battery;
determining an open circuit voltage for the battery;
determining a base capacity of the battery;
determining a first capacity reduction for the battery based on the battery specification and the base capacity, and a second capacity reduction for the battery based on the environmental condition information;
determining an overall expected capacity for the battery based on the first capacity reduction and the second capacity reduction, wherein the overall expected capacity represents available energy for the battery;
determining the available energy for the battery is less than a capacity buffer and a required energy to perform a final action prior to battery depletion, wherein the capacity buffer ensures the available energy for the battery is enough to perform the final action prior to the battery depletion;
sending a warning notification to a client device associated with the user; and
instructing the electronic device to disable one or more features based on an energy conservation protocol, wherein the energy conservation protocol increases the available energy for the battery above the capacity buffer and the required energy to perform the final action prior to the battery depletion.

2. The computer-implemented method of claim 1 , further comprising:
receiving device information for the electronic device; and
determining the required energy for the battery to perform the final action on the electronic device prior to the battery depletion based on the device information for the electronic device.

3. The computer-implemented method of claim 1 , further comprising:
instructing the electronic device to perform the final action prior to the battery depletion, wherein the electronic device has disabled the one or more features based on the energy conservation protocol.

4. The computer-implemented method of claim 1 , wherein the environmental condition information includes current environmental condition data and expected environmental condition data.

5. The computer-implemented method of claim 4 , wherein the current environmental condition data is for a first location of the battery and the expected environmental condition data is for a second location of the battery at a conclusion of a predetermined time frame.

6. A computer program product comprising one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media, the stored program instructions executable by one or more computer processors, the stored program instructions comprising:
program instructions to determine a battery supplying power to an electronic device associated with a user is discharging;
program instructions to receive battery specification information for the battery;
program instructions to receive environmental condition information for the battery;
program instructions to determine an open circuit voltage for the battery;
program instructions to determine a base capacity of the battery;
program instructions to determine a first capacity reduction for the battery based on the battery specification and the base capacity, and a second capacity reduction for the battery based on the environmental condition information;
program instructions to determine an overall expected capacity for the battery based on the first capacity reduction and the second capacity reduction, wherein the overall expected capacity represents available energy for the battery;
program instructions to determine the available energy for the battery is less than a capacity buffer and a required energy to perform a final action prior to battery depletion, wherein the capacity buffer ensures the available energy for the battery is enough to perform the final action prior to the battery depletion;
send a warning notification to a client device associated with the user; and
program instructions to instruct the electronic device to disable one or more features based on an energy conservation protocol, wherein the energy conservation protocol increases the available energy for the battery above the capacity buffer and the required energy to perform the final action prior to the battery depletion.

7. The computer program product of claim 6 , the stored program instructions further comprising:
program instructions to receive device information for the electronic device; and
program instructions to determine the required energy for the battery to perform the final action on the electronic device prior to the battery depletion based on the device information for the electronic device.

8. The computer program product of claim 6 , the stored program instructions further comprising:
program instructions to instruct the electronic device to perform the final action prior to the battery depletion, wherein the electronic device has disabled the one or more features based on the energy conservation protocol.

9. The computer program product of claim 6 , wherein the environmental condition information includes current environmental condition data and expected environmental condition data.

10. The computer program product of claim 9 , wherein the current environmental condition data is for a first location of the battery and the expected environmental condition data is for a second location of the battery at a conclusion of a predetermined time frame.

11. A computer system comprising:
one or more computer processors;
one or more computer readable storage media; and
program instructions stored on the computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising:
program instructions to determine a battery supplying power to an electronic device associated with a user is discharging;
