摘要
21世纪以来,全球的经济飞速发展,汽车的消费市场受到极大的刺激,随之而来的就是汽车保有量在全世界范围不断提升、能源消耗量越来越大和环境问题越来越让人担忧。为了应对这样的现状,各国政府一方面制定各种法规和标准限制能源的消耗;另一方面投入人力物力鼓励新能源技术的发展。
其中纯电动汽车是新能源技术发展的一条重要技术路线,它以电机为驱动装置、以电池为储能单元,具有能源利用率高、排放污染几乎为零、噪音污染小等诸多优点。本课题围绕纯电动汽车的选型和参数设计展开工作,本文设计的轻型电动物流车是运行在城市工况下,服务于物流行业货物配送环节的纯电动汽车,主要从城市工况特点、物流特点等方面入手提出其动力系统设计要求,然后进行参数匹配。
本文进行的轻型电动物流车动力系统设计对其他电动车的动力系统设计有一定的参考价值。
关键词:纯电动汽车,动力系统,城市物流,参数匹配
Abstract
Since the 21st century, the global economy has developed rapidly, and the consumer market for automobiles has been greatly stimulated. As a result, the number of car ownership continues to increase worldwide, energy consumption is increasing, and environmental issues are increasingly making people worry. In response to this situation, governments on the one hand formulate regulations and standards to limit energy consumption; on the other hand, they invest human and material resources to encourage the development of new energy technologies.

Among them, pure electric vehicles are an important technical route for the development of new energy technologies. They use motors as driving devices and batteries as energy storage units. They have many advantages such as high energy efficiency, almost zero emission pollution, and low noise pollution. This topic focuses on the selection and parameter design of pure electric vehicles. The light electric logistics vehicle designed in this paper is a pure electric vehicle that operates under the urban conditions and serves the logistics of goods distribution in the logistics industry, mainly from the characteristics of urban conditions, logistics Features and other aspects start with the requirements of its power system design, and then perform parameter matching.
The power system design of the light electric logistics vehicle carried out in this paper has certain reference value for the design of the power system of other electric vehicles.
Key words: pure electric vehicle, power system, urban logistics, parameter matching
