  "textContent": "The present disclosure relates to the technical field of batteries, and provides a method and a system for detecting a lithium plating state of a battery, a vehicle, a device, and a storage medium. The method includes: regularly collecting a voltage of a battery after the end of charging at a preset time interval after the battery is in an idle state, and associatively storing the collected voltage and a collection time of the voltage as voltage data; constructing a time-differential voltage curve in a voltage-time coordinate system according to the voltage data; detecting whether a characteristic peak voltage exists in the time-differential voltage curve; prompting that lithium plating occurs in the battery when detecting the characteristic peak voltage in the time-differential voltage curve; and prompting that the lithium plating does not occur in the battery when detecting no characteristic peak voltage in the time-differential voltage curve.",
