  "textContent": "Provided are a method and apparatus for determining a fast charging current limit of a battery cell, an electronic device, and a medium. The method includes: dividing a process of charging the battery cell into n charging stages based on electric quantity; determining a rebound potential value and a polarization potential value of each charging stage and a difference value between allowable lowest negative electrode potentials of adjacent charging stages in an order from larger to smaller values of n; calculating one or more charging current values of each charging stage based on the rebound potential value and the polarization potential value of the charging stage and the difference value between the allowable lowest negative electrode potentials of adjacent charging stages; and determining target fast charging current limits corresponding to different charging stages that satisfy a preset condition based on the one or more charging current values of each of the n charging stages. According to the embodiments of the present disclosure, the characteristic of the rebound potential of the battery cell is fully exploited to calculate a fast charging capacity limit of the battery cell, which greatly saves samples and test resources and has the advantages of high efficiency, accuracy, and cost-effectiveness.",
