The invention provides an electric vehicle distributed charging control method based on a consistency algorithm and a related device, and belongs to the technical field of electric power grids. The method comprises the steps of collecting charging parameters of the electric vehicle; based on the charging parameters, the charging cost micro-increasing rate of each electric vehicle is calculated, wherein the charging cost micro-increasing rate is the charging cost change rate of the electric vehicle with the purpose of minimizing the charging power loss of the electric vehicle; continuously iteratively updating the charging cost incremental rate and the residual available power of the charging station by adopting a consistency algorithm until convergence; and the convergence result is transmitted to an electric vehicle charging pile controller, and charging control is completed. According to the method, the charging loss problem of the electric vehicle is considered by adopting the charging cost increment rate, and the information interaction between the electric vehicle and the charging station is completed by adopting the consistency algorithm, so that the loss caused by the internal resistance of the battery of the electric vehicle is reduced to the greatest extent; and the charging control under the influence caused by the access of a large number of electric vehicles to the power grid is reduced.
