The invention discloses a charging load simulation method considering time-space charging selection of an electric vehicle, and the method comprises the steps: expanding a multi-period traffic network considering the time dimension influence based on a single-period traffic network of a conventional research; the travel and charging process of an electric vehicle is considered, a space-time charging selection model of a user is established in a multi-period traffic network, and the optimal travel space-time path of the user under the current condition is simulated based on the model; considering mutual influence of user behaviors, establishing a multi-period travel flow distribution model of the electric vehicle under traffic balance in a multi-period traffic network, and distributing travel flows of all users based on the model; based on the space-time charging selection model and the multi-period travel flow distribution model of the user, a branch pricing method is adopted to iteratively solve the problems of optimal space-time path selection of the current flow of the user and flow redistribution of all the users. According to the invention, the space-time charging load of the electric vehicle can be simulated more accurately and efficiently.
