At present, most relevant researches study the impact of charging electrical vehicles (EVs) on distribution network through simulation method. This method requires a large amount of input information and simulation calculation, and requires a large amount of simulation time. The required input information is difficult to be fully satisfied in the actual situation, which is easy to influence the evaluation effect. In order to overcome the drawbacks of the simulation method, an assessment model for evaluating the voltage influence caused by EV charging on distribution grid has been proposed in this paper, which can work with only the traditional distribution network input information for load flow calculation and historical charging load information at charge charging stations(FCS). The proposed model can perform early warning type assessment of voltage change, which can assist the distribution grid operators to find trouble nodes with high probability of voltage violation.
