    Abstract: A processor-implemented method with charging control includes: estimating respective step degradation amounts in charging steps of a first charging interval for each of first candidate current patterns of charging a battery from a first state of charge (SOC) level to a second SOC level during the first charging interval; determining an interval degradation amount in the first charging interval for each of the first candidate current patterns, based on the estimated step degradation amounts; and selecting a first representative current pattern indicating a minimum degradation amount from among the first candidate current patterns, based on the determined interval degradation amounts.

    Abstract: A processor-implemented method with battery state estimation includes estimating a current state of charge (SOC) of a target battery by correcting a first electrochemical model corresponding to the target battery using a first voltage difference between a measured voltage of the target battery and an estimated voltage of the target battery that is estimated by the first electrochemical model, estimating an end SOC of the target battery by correcting a second electrochemical model using a second voltage difference between an estimated voltage of a virtual battery that is estimated by the second electrochemical model and a preset voltage, and estimating a relative SOC (RSOC) of the target battery based on the current SOC and the end SOC of the target battery, wherein the second electrochemical model is based on the virtual battery corresponding to the target battery being discharged to reach the preset voltage.
