Abstract: A lithium-ion battery includes a cathode active material of the Olivine-type crystal structure. The lithium-ion battery is charged under control of a charging control apparatus, which performs a charging process for charging up to a target voltage according to a constant-current and constant-voltage charging method, a negative-electrode potential evaluation process for evaluating a potential change quantity at the negative-electrode, and a voltage setting process for setting the target voltage to a lower voltage based on the potential change quantity of the negative-electrode evaluated by the negative-electrode potential evaluation process. The charging voltage is changed from the target voltage to the set voltage even when the negative-electrode potential changes with an increase in the number of charging and aging deterioration. Thus a positive-electrode potential is suppressed from rising because of less susceptibility to the increase in number of charging and aging deterioration.
