Abstract
A method, an apparatus and a device for charging a battery are provided. The method may include: defining a charging current Ifor an Nth charging stage of a charging process based on charging capability of the battery, wherein I<I; defining a charge cutoff voltage Vfor the Nth charging stage of the charging process, wherein V>Vand Vis smaller than a theoretical charge cutoff voltage V; in case that the N-1th charging stage is not a last charging stage, charging the battery with Iduring the N-1th charging stage and proceeding to the Nth charging stage when a voltage across the battery reaches V; and in case that the N-1 th charging stage is the last charging stage, charging the battery with Iduring the N-1th charging stage and stopping charging when the voltage across the battery reaches V.
