Abstract
A method for charging a battery that is a non-aqueous electrolyte secondary battery includes first and second steps. The first step is estimating an SOC of the battery based on at least one of a voltage and a current of the battery. The second step is, based on a relationship between the SOC of the battery and an entropy change ΔS, determining a maximum charging current to the battery in accordance with the SOC of the battery such that the maximum charging current becomes larger as the entropy change of the battery becomes greater.
