    Abstract: According to one aspect, a method to estimate a state of a battery includes receiving physical quantity information about a sensed physical quantity of a battery, obtaining estimated information of the battery from a battery model based on the received physical quantity information. The battery model includes a training model configured to determine internal battery information comprising potential information of an internal material of the battery based on the physical quantity information and a mathematical function. The method further includes calculating an ion concentration in the battery using the mathematical function based on the internal battery information to determine the estimated information of the battery.

    Abstract: Provided is a method and apparatus for estimating a battery state. A method of estimating a battery state that includes determining whether a previous state to a rest state of a battery is a charging state or a discharging state; selecting a current profile comprising one or both of a charging pulse and a discharging pulse based on the previous state of the battery; stabilizing an open circuit voltage (OCV) of the battery by applying the current profile to the battery; and measuring the stabilized OCV.
