The invention provides a battery charging method, an electronic device, a storage medium and a program product, and relates to the technical field of terminals. The problem that in the charging process of a battery formed by connecting a plurality of battery cells in series, due to uneven voltage division of the battery cells, individual battery cells are overcharged can be solved. The method comprises the following steps: acquiring a current charging current and voltages of n battery cells; if the difference value between the maximum voltage in the voltages of the n battery cells and the preset charging voltage upper limit of the single battery cell is smaller than or equal to a preset difference value, determining a derated current, wherein the preset difference value is larger than or equal to 0, the maximum voltage is smaller than or equal to the charging voltage upper limit of the single battery cell, and the derated current is smaller than the current charging current; and instructing the derated curren
