1. A battery management method comprising:
determining, by a battery management system, 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;
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.
