电动公交车实际运行耗电量响应面模型研究

Study on Response Surface Model of Actual Power Consumption of Electric Buses

为了分析电动公交车的耗电量,本文采用青岛薛家岛充换电站统计数据,以起停次数、工作时间、行驶距离和电池温度为设计变量,建立电动公交车运行耗电量二次响应面模型,并分析了耗电量与各影响因素之间的关系。分析结果表明,通过运用Matlab绘制的耗电量与设计变量间的二次函数图像,能够直观且定量的反映出耗电量与各参数之间的关系。该模型在电动公交车耗电量分析中具有较高的准确性和可靠性,对电动公交车的运营及充换电站基础设施的建设起到重要的指示作用。

In order to analyze the power consumption of electric buses, the Response surface method of power consumption is established by using the stop times, working time, distance and the temperature of the battery as the design variables according to the statistical data form the Qingdao Xuejiadao filling sta- tion, which could analyze the relationship between consumption with its influencing factors. The analysis results show that the two function of the images between consumption and its design variables have been drawn by using MATLAB, which can reflect the relationship between electricity consumption and various parameters intuitively and quantitatively. The model has a high accuracy and reliability of actual power con- sumption of electric buses, which plays an important indication in the operation of electric bus and in the infrastructure construction of the charging station.
