The invention belongs to the technical field of vehicle network integration, and particularly relates to a charging scheduling method and system for electric vehicles, and the method comprises the steps: obtaining the shortest path of each electric vehicle from a starting point to a terminal point through each photovoltaic charging station; calculating the energy cost, the time cost and the charging cost of each shortest path; determining an optimal path and travel cost of each electric vehicle; calculating the total electric vehicle charging power of each photovoltaic charging station at each moment; calculating the charging and discharging power of an energy storage battery of each photovoltaic charging station at each moment; obtaining the optimal electricity price of each photovoltaic charging station at each moment; and performing charging scheduling according to the optimal electricity price and the optimal path. According to the method, the charging and discharging power of each energy storage battery is obtained by obtaining the optimal path and the stroke cost of each electric vehicle, the target function is obtained and solved by combining the stroke cost and the charging and discharging power of the energy storage batteries so as to minimize the total cost of all the electric vehicles, and it is ensured that the charging and discharging power of each energy storage battery is lower than the preset threshold value.
