Vehicle battery fault detection method and device, electronic equipment and storage medium

The invention provides a vehicle battery fault detection method and device, electronic equipment and a storage medium, and is applied to the technical field of vehicle early warning. To-be-detected fault alarm information uploaded by a vehicle end in real time is received; detecting whether the to-be-detected fault alarm information is real to-be-processed alarm information or not based on the target fault type of the to-be-detected fault alarm information and alarm verification information in a pre-established alarm signal verification database; if the to-be-detected fault alarm information is real to-be-processed alarm information, determining a fault early warning level corresponding to the to-be-detected fault alarm information based on a preset upgrading strategy and other fault types of other fault alarm information; and determining a target fault reason corresponding to the target fault type of the to-be-detected fault alarm information based on the fault early warning level of the to-be-detected fault
