Abstract
(EN) Provided are a battery charging method, an electronic apparatus, a storage medium and a program product, which relate to the technical field of terminals, and can solve the problem of overcharging of several cells due to uneven voltage division for cells during a charging process of a battery composed of a plurality of cells connected in series. The method comprises: acquiring the current charging current, and voltages of n cells; if the difference value between the maximum voltage among the voltages of the n cells and a preset single-cell charging voltage upper limit is less than or equal to a preset difference value, determining a de-rated current, wherein the preset difference value is greater than or equal to 0, the maximum voltage is less than or equal to the single-cell charging voltage upper limit, and the de-rated current is less than the current charging current; and providing an indication for charging a battery with the de-rated current.
(FR) Procédé de charge de batterie, appareil électronique, support de stockage et produit de programme, qui se rapportent au domaine technique des terminaux, et peuvent résoudre le problème de surcharge de plusieurs cellules due à une division de tension irrégulière pour les cellules pendant un processus de charge d'une batterie composée d'une pluralité de cellules connectées en série. Le procédé consiste à : acquérir le courant de charge actuel, et des tensions de n cellules ; si la valeur de différence entre la tension maximale parmi les tensions des n cellules et une limite supérieure de tension de charge de cellule unique prédéfinie est inférieure ou égale à une valeur de différence prédéfinie, déterminer un courant nominal réduit, la valeur de différence prédéfinie étant supérieure ou égale à 0, la tension maximale étant inférieure ou égale à la limite supérieure de tension de charge de cellule unique, et le courant nominal réduit étant inférieur au courant de charge actuel ; et fournir une indication pour charger une batterie avec le courant nominal réduit.
(ZH) 本申请提供一种电池充电方法、电子装置、存储介质及程序产品,涉及终端技术领域。能够解决多个电芯串联组成的电池在充电过程中由于各个电芯分压不均,导致个别电芯过充的问题。该方法包括:获取当前的充电电流,和n个电芯的电压;若所述n个电芯的电压中的最大电压与预设的单电芯充电电压上限之间的差值小于或者等于预设差值时,则确定降额电流,其中,所述预设差值大于或者等于0,所述最大电压小于或者等于所述单电芯充电电压上限,所述降额电流小于所述当前的充电电流;指示以降额电流为电池充电。
