1. A method of charging a target battery, the method comprising:
first charging a target battery using a battery model;
determining, by comparing a battery characteristic corresponding to a charging level of the target battery with respective stored battery characteristics corresponding to charging levels of a plurality of reference batteries, an aging mode of the target battery that reflects an aging factor and an aging degree of the target battery;
updating, based on the determined aging mode, the battery model to reflect the aging mode of the target battery; and
second charging the target battery using the updated battery model,
wherein each of the respective stored battery characteristics corresponds to a reference aging mode of a corresponding reference battery and represents respective information with respect to a charging level, a change in quantity of electric charge, and a change in voltage of the corresponding reference battery;
the determining of the aging mode further comprises:
applying a respective weight to each one or more stored battery characteristics among the respective stored battery characteristics;
and determining each of the respective weights based on a corresponding similarity between the battery characteristic corresponding to the charging level of the target battery and the one or more stored battery characteristics;
wherein, for each of the one or more stored battery characteristic, the corresponding similarity indicates a similarity of a peak characteristic in a graphing of a battery characteristic corresponding to the charging level of a corresponding reference battery to a peak characteristic in a graphing of the battery characteristic corresponding to the charging level of the target battery.
