  "textContent": "Embodiments of this application provide a method and device for detecting charging abnormality, and a storage medium, and relate to the technical field of battery charging. In this application, a first sampling moment corresponding to a first minimum voltage in n sampled voltages is determined based on n consecutive sampled voltages of a first cell from an end moment of an i charging phase to an end moment of an (i+1) charging phase in a k charging process. A second sampling moment corresponding to a second minimum voltage in any one of the first (k-1) charging processes can be determined in the same way. Then abnormality of the k charging process is determined based on the first minimum voltage and the second minimum voltage; or, abnormality of the k charging process is determined based on a rate of change of the sampled voltages in a first period after the first sampling moment in the k charging process and a rate of change of the sampled voltages in a second period after the second sampling moment in any one of the first (k-1) charging process, so that the accuracy of detecting charging abnormality is improved and the misjudgment rate is reduced effectively.",
