Abstract

A Battery Management System (BMS) for an electronic device with bidirectional communication between The BMS and an Operating System (OS) of the electronic device for generating a charging pattern of charging the battery of the electronic device according to information received from the operating system.

First claim

What is claimed is:

1 . A method of managing a battery of an electronic device, the method comprising:
obtaining first information of functional parameters of the battery; obtaining second information of at least one of an operational status of the electronic device and user activity; and generating a charging pattern to charge the battery based on the first information and the second information.

2 . The method of claim 1 , further comprising:
obtaining heuristic information related to at least one of previous functional parameters of the battery, a previous status of the electronic device, and previous user activity, wherein the generating comprises generating the charging pattern based on the heuristic information.

3 . The method of claim 2 , further comprising:
obtaining information of actual power management of the electronic device based on the charging pattern to be stored as the heuristic information.

4 . The method of claim 1 , wherein the generating comprises:
determining a period of time during which the battery is capable of supporting operation of the electronic device based on the first information and the second information; and generating the charging pattern based on the period of time.

5 . The method of claim 4 , further comprising:
notifying a user of a time to charge the battery of the electronic device based on the period of time.

6 . The method of claim 1 , wherein priorities are set amongst the first information and the second information, and
wherein the generating comprises generating the charging pattern based on the priorities for the first information and the second information.

7 . The method of claim 1 , wherein the charging pattern comprises at least one of a time, a period, a rate, an interval, and an extent for charging of the battery.

8 . The method of claim 1 , wherein the operational status of the electronic device includes at least one of a parameter pertaining to applications in the electronic device, ambience of the electronic device, and operational parameters of the electronic device, and
wherein the user activity comprises at least one of an actual time and a period of charging the battery, a time and a period of using the electronic device, and information inputted by the user through applications of the electronic device.

9 . An electronic device comprising:
a memory configured to store computer-readable instructions; and a processor configured to execute the computer-readable instructions, which when executed cause the BMS to obtain information of functional parameters of a battery of an electronic device, obtain first information of at least one of an operational status of the electronic device and user activity, generate at least one charging pattern to charge the battery based on the first information and the second information.

10 . The device of claim 9 , wherein the processor is further configured to obtain heuristic information related to at least one of previous functional parameters of the battery, a previous status of the electronic device, and previous user activity, and generate the charging pattern based on the heuristic information.

11 . The device of claim 10 , wherein the processor is further configured to obtain information of actual power management of the electronic device based on the charging pattern to be stored as the heuristic information.

12 . The device of claim 9 , wherein the processor is further configured to determine a period of time during which the battery is capable of supporting operation of the electronic device based on the first information and the second information, and generate the charging pattern based on the period of time.

13 . The device of claim 12 , wherein the processor is further configured to control output of an indication of a time to charge the battery of the electronic device based on the period of time to a user of the electronic device.

14 . The device of claim 9 , wherein the processor is further configured to set priorities amongst the first information and the second information, and generate the charging pattern based on the priorities for the first information and the second information.

15 . A non-transitory computer-readable medium having stored thereon computer-executable instructions that when executed by a processor of an electronic device cause the processor to perform a method of managing a battery of the electronic device, the method comprising:
obtaining first information of functional parameters of the battery; obtaining second information of at least one of an operational status of the electronic device and user activity; and generating a charging pattern to charge the battery based on the first information and the second information.

16 . The non-transitory computer-readable medium of claim 15 , wherein the method further comprises:
obtaining heuristic information related to at least one of previous functional parameters of the battery, a previous status of the electronic device, and previous user activity, wherein the generating comprises generating the charging pattern based on the heuristic information.

17 . The non-transitory computer-readable medium of claim 15 , wherein the method further comprises:
obtaining information of actual power management of the electronic device based on the charging pattern to be stored as the heuristic information.

18 . The non-transitory computer-readable medium of claim 15 , wherein the generating comprises:
determining a period of time during which the battery is capable of supporting operation of the electronic device based on the first information and the second information; and generating the charging pattern based on the period of time.

19 . The non-transitory computer-readable medium of claim 18 , further comprising:
notifying a user of a time to charge the battery of the electronic device based on the period of time.

20 . The non-transitory computer-readable medium method of claim 15 , wherein priorities are set amongst the first information and the second information, and
wherein the generating comprises generating the charging pattern based on the priorities for the first information and the second information.
