BATTERY, ELECTRICITY UTILIZATION APPARATUS, AND BATTERY CHARGING METHOD AND APPARATUS

Embodiments of this application provide a battery, an electric apparatus, and a charging method apparatus for battery, and belongs 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. The historical capacity decline increases constantly along with use of the battery. Therefore, in this application, the full charge voltage of the battery in the charging process also increases constantly, or the full charge voltage is opened constantly. In this way, the decline of the battery capacity can be compensated for at each time of charging, so that the battery truly reaches full charge, thereby guaranteeing that the capacity of the battery does not decline at discharging.
