Marketing Strategy of New Energy Car [PDF]
摘要 目前道路上行驶的传统汽车,使用的是油,排出的是碳。而作为传统能源的石油则是不可再生的,国际原油价格跌跌涨涨,牵动着亿万人的心,同时,由此可见,无论是从节约能源来讲,还是从减少污染排放来看,传统汽车的发展已受到诸多因素的制约,业界在呼唤汽车能源的革命,正在力图推动新能源汽车的发展。同时新能源汽车也因其独有的特点,受到各大汽车制造企业的追捧,并且成为未来汽车工业发展的方向。但是由于我国新能源汽车发展较世界先进的汽车发达国家晚,并且产品现状与传统车相比还存在着一定差距,比如:续航能力,行驶速度,产品价格,

随着直流微电网系统的广泛应用,其控制技术得到不断关注。直流微电网系统由光伏阵列、电动汽车充换站、大电网及其接口变换器构成。针对其结构特点,采用一种能量协调控制策略以维持直流母线的电压稳定。该控制策略根据直流微电网中母线电压信息(DBS)进行运行模式划分,不同运行模式下,直流微电网各单元的控制策略可进行无缝切换,实现系统协调自治。采用下垂控制实现对多个光伏阵列或者电动汽车蓄电池模块的功率均分。仿真结果表明,直流母线电压保持稳定的同时,直流微电网系统能够在并离网不同模式间进行平滑切换 ...

针对大功率电动汽车(electric vehicles,EVs)的运行特点,基于开放式绕组感应电机的驱动方式成为电动汽车额重要研究趋势之一。与传统感应电机相比,开放式绕组感应电机(open-end winding induction motor,OEWIM)在给定的扭矩下只需要直流母线电压的一半。基于此,文中提出了一种基于双两电平电压源逆变器(voltage source inverter,VSI)供电的电动汽车储能系统两阶段模型预测直接转矩控制(MPDTC)方法,以实现EVs储能系统中荷电状态SoC ...
