Construction method and device of electric vehicle load spectrum, medium and electronic equipment

The invention relates to the technical field of vehicle racks, in particular to an electric vehicle load spectrum construction method and device, a medium and electronic equipment, and the method comprises the steps: S1, obtaining a road spectrum for an electric vehicle, and obtaining a target damage model corresponding to a target part; s2, according to the road spectrum, calculating a first relative damage value of the target part through a target damage model; s3, acquiring a motor performance curve of the electric driving unit, and constructing a rack load spectrum of the electric driving unit based on the motor performance curve; s4, according to the rack load spectrum, calculating a second relative damage value of the target part through the target damage model, and calculating a damage ratio of the second relative damage value to the first relative damage value; and S5, adjusting the rack load spectrum, and circularly executing the step S4 until all the damage ratios meet the preset conditions, and out
