The invention discloses a charging load control method and device for an electric vehicle charging station. The method comprises the following steps: acquiring target data associated with a target charging station in a target time period, the target data comprises a capacity upper limit of a distribution transformer in a district to which the target charging station belongs, a basic load capacity under the distribution transformer, the number of alternating current charging piles and direct current charging piles in the target charging station, a charging price and charging demand information of a charging vehicle; according to the target data and a target working state of the target charging station, constructing a target function and a constraint condition, the target working state being a to-be-solved quantity, and the target function at least comprising one of a charging cost optimization function, a charging time penalty function, a charging fluctuation penalty function and a power grid peak clipping and valley filling optimization function; and solving the target function under constraint conditions to obtain a target charging control strategy of the target charging station. According to the invention, the technical problem that the charging strategy of the charging station lacks adaptability to the power supply of the area in which the charging station is located in the prior art is solved.
