The invention relates to the technical field of electric vehicle charging control, and provides a variable-duration two-stage electric vehicle scheduling method and system based on a grid method.The method comprises the steps that pre-scheduling is conducted on electric vehicles participating in contract charging on idle days, and a pre-scheduling load curve is obtained; setting a scheduling period by taking the pre-scheduling load curve as a basic load curve, obtaining a plurality of different scheduling moments according to the scheduling period, and constructing a charging station time grid containing charging station information for each charging station by taking a set moment from the scheduling moment to the next day as a scheduling duration corresponding to each scheduling period; and two-stage scheduling of variable-duration rolling based on a grid method is carried out, the two-stage scheduling comprises charging station scheduling and electric vehicle scheduling, and the charging and discharging pow
