The invention discloses a highway electric vehicle charging load prediction method and system. The method comprises the following steps: constructing a target highway entrance and exit vehicle OD matrix; preliminarily calculating the total number M of the electric vehicles running on the target highway; initializing initial parameters of all the electric vehicles; based on the initial parameters of the mth electric vehicle, generating operation parameters for the mth electric vehicle; mapping the operation parameters of the mth electric vehicle to the expressway road network model; the travel time, the state of charge and the remaining mileage of the mth electric vehicle in the expressway road network model are updated; estimating whether the mth electric vehicle in the expressway road network model needs to be charged in the service area, if so, calculating the charging duration of the mth electric vehicle, if not, judging whether the remaining mileage is zero, judging whether m is smaller than M or not, if not, calculating the total charging load of each expressway service area, and ending.

    本发明公开了一种高速公路电动汽车充电负荷预测方法及系统,包括:构建目标高速公路出入口车辆OD矩阵;初步计算出目标高速公路行驶电动汽车的总数量M;初始化所有电动汽车的初始参数;基于第m辆电动汽车的初始参数,为第m辆电动汽车生成运行参数;将第m辆电动汽车的运行参数,映射到高速公路路网模型中;更新高速公路路网模型中第m辆电动汽车的出行时间、荷电状态以及剩余里程;预估高速公路路网模型中的第m辆电动汽车是否需要在服务区充电,如果需要充电,则计算第m辆电动汽车的充电时长,如果不需要充电,则判断剩余里程是否为零,判断m小于M是否成立,如果不成立,就计算各个高速公路服务区的充电总负荷,结束。
