Abstract: A battery management method and system are provided. The method includes acquiring one or more parameters associated with the battery. The one or more parameters includes a current level, a voltage level, a State of Charge (SOC), and a temperature. The method includes determining a load and energy estimation model based on the one or more acquired parameters. The method includes identifying a power limit of the battery based on the load and energy estimation model. The method includes determining a power margin of the battery at a first usage time interval based on the identified power limit. The method includes performing one or more actions, based on a determination that the power margin of the battery exceeds a predefined threshold level.

Abstract: A method and apparatus for determining safety of a battery are disclosed, where the method includes identifying a charge state or a discharge state of the battery, activating pulse probe currents at different depths of charge or discharge (charge/discharge) of the battery, in response to identifying the charge or discharge state of the battery, and detecting and differentiating between a state of short (SOS) and a state of health (SOH) of the battery based on variations of the pulse probe currents as a function of the depths of charge/discharge.

Abstract: A battery management system and method to control charging of a battery is provided. The system determines whether a current capacity of the battery is greater than a predetermined threshold percentage of an original rated capacity of the battery, in response to initiation of a charging cycle of the battery being detected, controls the battery to be charged with a first voltage, in response to the current capacity of the battery being determined to be greater than the predetermined threshold percentage of the original rated capacity of the battery, and controls the battery to be charged with a second voltage, in response to the current capacity of the battery being determined to be less than or equal to the predetermined threshold percentage of the original rated capacity of the battery.
