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 system that enhances a service life of a battery is provided. The method includes values of a set of operational characteristics of a plurality of electrochemically active materials of at least one electrode of the battery. The set of operational characteristics include a voltage, a change in accumulated energy, a change in ohmic resistance, and a change in a rate of change in accumulated energy with respect to a rate of change in ohmic resistance. The values are compared with predefined values of the set of operational characteristics. A rate of depletion and a type of depletion of each of the plurality of electrochemically active materials are determined, and a range of the State of Charge, a range of the voltage, and a range of current to operate the battery for enhanced service life are determined.

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.
