The invention relates to the field of electric vehicle charging, in particular to a method for electric vehicle charging scheduling in extreme weather, which comprises the following steps: S1, acquiring a reference array which comprises a reference time period regulation difference index Ci and an optimal charging time period Ti, and calculating the reference time period regulation difference index Ci and the optimal charging time period Ti through a prediction model, the length of the reference array is the number of days of one cycle; s2, calculating a prediction time period regulation and control difference index Cm of the to-be-predicted day through the prediction model; and S3, finding Ci closest to the Cm in the reference array, extracting Ti corresponding to the Ci, and providing scheduling suggestions for the charging time period of the electric vehicle according to the Ti. A more accurate result is obtained by adding the influence of temperature and humidity in extreme weather on the charging demand of the electric vehicle into the simulation model; by constructing the reference array, the calculation amount during scheduling can be reduced, and the efficiency and accuracy of predicting the scheduling suggestion can be improved.
