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 on functional parameters for indicating a status of the battery;
obtaining second information on user activity for the electronic device;
obtaining third information on an operational status of the electronic device;
identifying that a charge of the battery is required based on the first information, the second information, and the third information;
determining at least one charging scheme to charge the battery based on the first information, the second information, and the third information after identifying that the charge of the battery is required; and
performing an action for charging the battery according to the determined at least one charging scheme.

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 determining the at least one charging scheme comprises determining the at least one charging scheme 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 at least one charging scheme to be stored as the heuristic information.

4. The method of claim 1 , wherein the identifying that the charge of the battery is required comprises:
determining a period of time during which the battery is capable of supporting an operation of the electronic device based on the first information, the second information, and the third information;
determining a power required by the electronic device for maintaining functionalities of the electronic device; and
identifying that the charge of the battery is required based on the period of time and the power required by the electronic device.

5. The method of claim 4 , further comprising:
detecting that a power source is not connected to the electronic device; and
displaying, on a screen of the electronic device, a message for indicating to charge the battery of the electronic device in response to detecting the power source is not connected.

6. The method of claim 1 , wherein priorities are set amongst the first information, the second information, and the third information, and
wherein the determining the at least one charging scheme comprises determining the at least one charging scheme based on the priorities for the first information, the second information, and the third information.

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

8. The method of claim 1 , wherein the operational status of the electronic device includes at least one of an ambience of the electronic device and operational parameters of the electronic device,
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 a user through applications of the electronic device, and
wherein the operational parameters of the electronic device comprise at least one of a current limit, a thermal limit, a processor temperature, and a minimum operating voltage.

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 a battery management system (BMS) to:
