Improving EV efficiency through the use of a continuously variable transmission

“动力系统专家越来越多地达成共识，电动汽车需要发展多速变速器，如果他们要实现其全部潜力”这是最近一篇文章的标语“国际变速器技术”该报告称，工业界已经认识到电动汽车内需要变速器。该项目旨在研究通过将可变变速器纳入电动汽车中可以实现的整体效率增益。车辆，而不是普通的单速变速器。变速传动装置将克服诸如换档过程中的能量损失和乘客不适等缺点。这将使能源效率的显着改善，以及潜在的允许电动机被缩小。最初的模型研究表明，可以实现16%的改进。这些改进将在项目期间进行量化，以证明电动汽车范围的增加。该项目将利用安装在电动日产Cabstar上的Mazaro变速器变速器。Mazaro变速箱采用了一种新颖的方法，在所有速比下都能产生非常高的机械效率，因此非常适合本项目。

"There's a growing consensus among powertrain experts that EVs need to evolve multi-speed transmissions ifthey are to realize their full potential" This is the tagline from a recent article in "Transmission TechnologyInternational" which reports that industry has recognised the need for a transmission within an electric vehicle.This project is to investigate the overall efficiency gains that can be achieved by including a variabletransmission into an electric vehicle instead of the normal single speed transmission. A variable speedtransmission would overcome drawbacks such as energy loss during shifting and passenger discomfort. This willallow significant improvements in energy efficiency to be made as well as potentially allowing the electricmotor to be downsized. Initial modelling studies have indicated that improvements of 16% could be achieved.The improvements will be quantified during the project to prove the increase in EV range The project will utilisea Mazaro Variator transmission fitted to an electric Nissan Cabstar. The Mazaro transmission has a novelapproach, which produces a very high mechanical efficiency at all speed ratios and so is ideal for this project.
