电动汽车估算策略综述

A comprehensive review on estimation strategies in Battery electrical vehicle

近年来,由于混合动力和纯动力电动汽车能有限减少燃料消耗,减少对进口石油的依赖和温室气体排放而在全球范围内受到广泛关注。电动汽车的全面性成功主要取决于他们所创建的子系统的性能。为了提高这些子系统的性能,对其参数的估算精度要求非常之高。此外,估算策略在电池系统和车辆能量管理上发挥了重要作用。有少数的估算策略相关的综述,但只关注于电池的核电状态(SOC)和健康状态(SOH)的估计。文章对混合动力和纯动力电池汽车的各种估计策略做了全面综述,对现有的估计策略进行分类,并阐述每个估计策略中使用的不同方法。

In recent years, a significant interest in hybrid and battery electric vehicles has arisen globally due toreducing fuel consumption, mitigating dependence on imported oil and decreasing greenhouse gasemissions. The overall success of these vehicles mostly depends on the performance of sub-systems thatthey are created. In order to enhance the performances of these sub-systems, estimation of theirparameters with high accuracy is required. Furthermore, estimation strategies play an important role inbattery management, vehicle energy management and vehicle control by undertaking different tasks.There have been a limited number of review studies related with estimation strategies that are onlyfocused on battery state of charge(SOC) and state of health(SOH) estimation. This paper presents acomprehensive review on various estimation strategies used in hybrid and battery electric vehicles forthe first time in the literature. The existing estimation strategies are classified and different methodologies used in each estimation strategy are elaborated. Recent research advances on existing estimationstrategies are clearly emphasized.
