摘要： 针对集中充电模式下电动汽车的充电特性，建立了基于该模式的电池更换站及道路模型，然后提出了用电动
汽车所消耗电量计算充电负荷的方法，进行了误差分析，导出了方差系数与电动汽车数量之间的关系，并通过蒙特卡洛
仿真算例，验证了该计算方法的精度。

Abstract: For the charging characteristics of electric vehicles in centralized charging mode, a battery replacement station and
road model based on this model were established. This paper proposed a method for calculating the charging load by using the
power consumed by electric vehicles, carried out an error analysis, derived the relationship between the variance coefficient and
the number of electric vehicles and then verified the accuracy of the calculation method by Monte Carlo simulation example.

Key words: electric vehicle; centralized charging mode; variance coefficient
