摘要： There are provided a battery charging method. The method includes (a) obtaining voltage capacity ratios for a reference charge C-rate and N (N is an integer of 1 or more) charge C-rates which are larger than the reference charge C-rate, the voltage capacity ratio being defined as a ratio of a voltage variance to a capacity variance depending on a change in SOC (state of charge) of a battery when the battery is charged with each of the C-rates, (b) comparing the voltage capacity ratio of the reference charge C-rate with each of the voltage capacity ratios of the N charge C-rates, and then setting a charge C-rate among the N charge C-rates so that a difference in voltage capacity ratio is minimized for each of SOC sections, and (c) charging the battery with the charge C-rate that is set for each of the SOC sections.
