Abstract:

Prediction is made mainly according to the load generated by charging of various types of electric vehicles in group. Based on the current state of the development of China’s electric vehicles, electric vehicles are divided into four categories on the basis of purpose which are electric buses, electric taxis, electric official cars and electric private cars.Different types of electric vehicles have different charging characteristics, charging methods and charging time. The initial state of charge (SOC) and the initial charge time are extracted by using the Monte Carlo simulation method. The charge loads of four types of electric vehicles are calculated and the corresponding load characteristic curve is simulated in C++ language, where then overall load curve is obtained. By analyzing the characteristics of the load curve, the overall trend of electric vehicle charging load in the future is obtained, which will provide guidance for the rapid development and construction of electric vehicle.
