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.

Abstract: 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.
