Method and system with battery management

A battery management method comprising:

• determining, by a battery management system, a load and energy estimation model based on at least one acquired parameter associated with the battery, wherein the at least one parameter comprises a current level, a voltage level, a state of charge (SOC), a temperature, or a combination of at least two of the parameters thereof;
• identifying, by the battery management system, a power limit of the battery based on the load and energy estimation model;
• determining, by the battery management system, a power margin of the battery at a first usage time interval based on the identified power limit;
• and
• performing, by the battery management system, at least one action, based on a determination that the power margin of the battery exceeds a predefined threshold level,
• wherein the at least one action comprises notifying a user to close at least one application running in an electronic device, notifying the user to close at least one background application running in the electronic device, reducing a clock speed of a processor of the electronic device, notifying the user of a remaining capacity of the battery, notifying the user of a maximum current extractable from the battery at a discharge condition, notify the user of a temperature dependent effect of the battery, predicting a state of health (SOH) of the battery, providing a route based on power demands in a vehicle, notifying a user of the vehicle to charge the battery, or a combination of at least two of the actions thereof.

A battery management system, comprising:

• one or more processors;
• a memory;
• and
• a load and energy estimation model configuration controller, coupled with the one or more processors and the memory, and configured to:
• determine a load and energy estimation model based on obtaining a pulse duration of a battery, a depth of discharge of the battery, a cut-off voltage associated with a pre-set voltage of the battery, and a temperature of the battery based on at least one acquired parameter associated with the battery,
• wherein the at least one parameter comprises a current level, a voltage level, a state of charge (SOC), a temperature, or a combination of at least two of the parameters thereof;
• identify a power limit of the battery based on the load and energy estimation model;
• determine a power margin of the battery at a first usage time interval based on the identified power limit;
• and
• perform at least one action based on a determination that the power margin of the battery exceeds a predefined threshold level.

An apparatus, comprising:

• one or more processors, configured to:
• determine a load and energy estimation model based on obtaining a pulse duration of a battery, a depth of discharge of the battery, a cut-off voltage associated with a pre-set voltage of the battery, and a temperature of the battery based on an obtained parameter associated with a battery;
• identify a power limit of the battery based on the determined load and energy estimation model;
• determine a power margin of the battery at a usage time interval based on the identified power limit, and
• perform a user-based action when the power margin is determined to exceed a predetermined threshold level.
