Disclosed are a battery charging control method and apparatus, and a battery powered device such as an electric vehicle. The method, for each cell in at least one cell of a multi-cell battery, includes: after the multi-cell battery enters a charging stable state, acquiring actual charging electric quantity required for charging the cell to a target voltage; determining a balance time duration for the cell based on the actual charging electric quantity corresponding to the cell, wherein the balance time duration is a time duration required for a cell balance control circuit matched with the cell to control the cell; and controlling the cell balance control circuit matched with the cell to perform electric quantity adjustment on the cell within the balance time duration. The technical problem of low accuracy of balance control on each cell in the multi-cell battery in the related art is solved.
