The invention provides a large-scale electric vehicle charging scheduling method and device based on an improved DQN, and a medium, and relates to the technical field of electric vehicle charging scheduling. The method comprises the following steps: S1, acquiring first power grid information; and S2, inputting the first power grid information into an electric vehicle selection network to obtain an expected profit value of charging scheduling of each electric vehicle. And S3, according to the expected profit value, the schedulable electric vehicle with the minimum Q-value in the current state is selected. And S4, constructing the state vector of the selected electric vehicle and the state information of all the current available charging equipment into second power grid information. And S5, inputting the second power grid information into the charging state selection network to obtain the charging return value estimation of the currently selected electric vehicle. The charging state selection network comprises a convolutional neural network-based feature extraction module, a noise-based exploration module INEM and a full connection layer FC which are connected in sequence. And S6, according to the return value estimation, selecting the charging pile with the minimum estimation value to charge the electric vehicle.
