Abstract

The present application relates to method and apparatus for determining a lithium plating potential of a battery cell, storage medium, and electronic device, wherein the method includes: obtaining a voltage and a capacity of the battery cell at different charging rates, and a voltage and a capacity of the battery cell at the same discharge rate; plotting a first relationship curve and a second relationship curve; plotting a charging capacity differential curve based on the first relationship curve, and plotting a discharge capacity differential curve based on the second relationship curve; and finally determining the lithium plating potential of the battery cell based on the two differential curves.
