摘要： 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.

摘要： A method and apparatus with battery short circuit detection are included. In one general aspect, a processor-implemented method includes, based on battery data measured by a battery and a battery model of the battery, determining a detection parameter value used for detecting a short circuit of the battery and a variation factor value correlated with the detection parameter, using the variation factor to extract a reference value corresponding to the detection parameter value from a reference data set, and determining whether a short circuit of the battery has occurred based on a result of comparing the detection parameter value with the reference value.
