Abstract: 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.

Abstract: A processor-implemented method with battery cell charging includes: for each degradation parameter set comprising one or more degradation parameters related to degradation, communicating with a server configured to generate and store a look-up table (LUT) comprising charge data for each index combination of the one or more degradation parameters comprised in the degradation parameter set; determining a current value of the one or more of the degradation parameters corresponding to a target battery cell of an electronic device and transmitting the current value to the server; receiving an LUT corresponding to the current value of the one or more degradation parameters from the server; and charging the target battery cell based on a charging profile that is generated by charge data of the received LUT.
