本文中提出一种基于动力电池能量状态估计和车辆能耗预测的续驶里程估计模型。电池能量状态估计采用电池状态模型估计电池剩余的可用能量，分析了不同因素的影响。利用纯电动车测试数据，基于递推最小二乘算法辨识车辆能耗参数，结合行驶工况预测汽车能耗，进而计算续驶里程。与传统的续驶里程估计方法相比，基于电池能量状态估计和整车能耗预测的续驶里程估计模型的精度有较大提高。

In this paper, a driving range estimation model is proposed based on the energy state estimation of traction battery and vehicle energy consumption prediction. On one hand, battery state model is built to estimate the remaining usable energy of battery and analyze the effects of different factors on it. By using vehicle test data, the energy consumption parameters of vehicle are identified with recursive least-squares algorithm, and with the driving conditions predicted, the energy consumption of vehicle and hence the driving range are calculated. Com-pared with the conventional methods, the driving range estimation model proposed based on battery energy state esti-mation and vehicle energy consumption prediction is more accurate.
