To generate a charging path for a battery, a method includes generating simulation data for charging currents based on a battery model indicating an internal state of a battery, generating an initial look-up table (LUT) for the charging currents and preset battery voltage limits based on the simulation data, the initial LUT representing initial charging limit conditions of the battery for stages corresponding to the charging currents, generating a modified LUT by adjusting at least one of the initial charging limit conditions of the initial LUT, in response to the initial LUT failing to satisfy a threshold, determining a final LUT based on the modified LUT, in response to the modified LUT satisfying the threshold, and generating a charging path for the battery based on the final LUT.

Method and apparatus for generating charging path for battery

A short circuit detection method includes obtaining battery data associated with a state of a battery from a charging cycle of the battery, estimating an error in the battery data using an estimation model, determining a state indicator corresponding to the error in the battery data, and detecting a short circuit of the battery based on a result of comparing the state indicator and a short circuit threshold.

Method and apparatus with battery short circuit detection

A method and apparatus for detecting an internal short circuit in a battery are provided. The method includes acquiring values of one or more basic parameters of the battery, acquiring values of one or more degradation parameters used in a battery model indicating an internal state of the battery based on the values of the one or more basic parameters, determining whether the internal short circuit occurs in the battery based on a first value of a first degradation parameter and a second value of a second degradation parameter from among the one or more degradation parameters, and performing an operation in response to the internal short circuit occurring in the battery.

Method and apparatus for detecting internal short circuit in battery

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.
