Mains supply fluctuation-resistant charging method, charging terminal and computer readable storage medium

The invention discloses a mains supply fluctuation-resistant charging method, a charging terminal and a computer readable storage medium. The method comprises the following steps: dividing the charging process of a battery pack into a plurality of charging stages, and using different charging currents in each stage; and when the charging process is interrupted and recovered, reducing the range points of the plurality of charging orders to divide a new charging stage range, and after the charging stage of the current battery pack is re-judged, charging the battery pack by using the charging current corresponding to the charging stage. The problems that the battery cannot be fully charged and potential safety hazards exist due to overlarge charging current caused by the fact that the current charging stage is judged to be the previous charging stage because the judgment of the battery management system on the current charging current of the battery pack is influenced because the voltage of the battery pack is r
