Abstract
Embodiments of this application provide a battery, an electric apparatus, a battery charging method, and an apparatus for charging a battery. The technical solutions provided by the application belong to the field of battery charging technologies. In this application, a historical capacity decline of the battery is determined based on capacity decline in a k-th discharging process and a capacity decline in previous k−1 discharging processes, a full charge voltage in an m-th charging process is determined based on the historical capacity decline, and then m-th charging is performed, based on the determined full charge voltage in the m-th charging process, on the battery. Because the historical capacity decline increases constantly with the use of the battery, in this application, the full charge voltage of the battery in the charging process is increased constantly, or the full charge voltage is opened up constantly.
