Electric vehicle fault monitoring method and device and computer readable storage medium

The invention discloses an electric vehicle fault monitoring method and device and a computer readable storage medium, and the method comprises the steps: screening operation parameter data based on a first preset feature parameter set, and obtaining a division interval of a second feature parameter based on the parameter property of each feature parameter in a second preset feature parameter set; dividing the screened operation parameter data based on the division interval of the second feature parameter to obtain a plurality of sub-data spaces; obtaining target data corresponding to the sub-data space based on the operation parameter data of the sub-data space; and determining whether the electric vehicle is a fault vehicle based on the target data. The data of the electric vehicle is divided, so that the data volume needing to be processed during fault detection is greatly reduced, the fault detection efficiency of the electric vehicle is improved, the configuration of the server is reduced, and then the c
