摘 要：伴随着我国经济的不断发展，在能源开采速度加快的情况下，目前全球的石油资源逐渐的减少，面临着枯竭的危险。在传统的汽车研究应用发展过程中，一般都是采用燃油的方式，但在环境保护约束和可持续性发展的重度影响下，燃油汽车并不适宜于现在当下的新时代环保策略。因此，为了更好地找出代替石油能源的新能源汽车种类，目前人们才用天然气以及电池能源形式来代替原有的燃油汽车。这些新能源汽车成为全球未来发展方向的同时，也能够使可持续性发展战略在环境保护的政策下能够更好的长效性发展。由于天然气和电力相比于石油而言更加的纯净，不具备污染性质，所以目前纯电动汽车的市场前景非常的良好，受到了人们的热议关注。本文主要根据新能源汽车轻量化的途径进行分析，并提出一些评价建议，以供参考。

Abstract：With the continuous development of China's economy and the acceleration of energy extraction， the current global oil resources are gradually decreasing and are facing the danger of exhaustion. In the process of traditional automobile research and application development， fuel is generally used. However， under the heavy influence of environmental protection constraints and sustainable development， fuel-fueled vehicles are not suitable for the current environmental protection strategy of the new era. Therefore， to better find out the types of new energy vehicles that replace petroleum energy， people currently use natural gas and battery energy to replace the original fuel vehicles. While these new energy vehicles have become the future development direction of the world， they can also enable sustainable development strategies to develop better and longer-term under environmental protection policies. Since natural gas and electricity are purer than oil and not polluting， the current market prospects for pure electric vehicles are very cool， and they have received heated attention from people. This article mainly analyzes the light-weight approach of new energy vehicles， and puts forward some evaluation suggestions for reference.

1 新能源汽車轻量化的必要性

当前我国社会经济发展速度迅速，能源的消耗量相较于90年代而言正在日益的提升。由于各行各业对于能源的需求量飞升较快，特别是在一些重工业和产品生产方面更加促进了能源的使用速度。从整体的消耗和储备占比而言，目前社会正处于一个能源和资源匮乏的年代，如果不能有效地规划使用能源，那么后期在能源枯竭的情况下，整个地球的环境也会受到非常大的影响。……
