摘要
基于MATLAB/Simulink建立电动汽车整车模型,并通过该模型选择工况特征参数进行工况的聚类分析,从而得到对应工况的能耗,最后根据剩余能量和能耗计算并由模型输出剩余里程。电池能量状态与能耗估计相结合不仅可以提高剩余里程估计的精度,也可以解决工况急剧变化的情况下估计结果的波动问题。
Based on MATLAB/Simulink,a complete model of electric vehicle was established,and the characteristic parameters of the working conditions were selected for the cluster analysis of the working conditions,so as to obtain the energy consumption of the corresponding working conditions.Finally,the remaining mileage was calculated according to the remaining energy and energy consumption as well as output by the model.The combination of battery energy state and energy consumption estimation can not only improve the accuracy of residual mileage estimation,but also solve the problem of fluctuation of estimation results under the condition of sharp change of operating conditions..
