摘 要:汽车产业是推动我国国民经济迅速发展的关键产业之一,但是随着环保意识的增强及能源危机的显现引发全社会的广泛关注。作为新能源技术纯电动汽车的研究越发成为解决能源危机的重要途径。近年来中国新能源汽车发展迅速,成为技术创新和产业升级的亮点领域。但是,目前在电动汽车技术中对电池技术的开发研究仍然没有在续航里程和充电难上找到令人满意的解决方案,这也使得纯电动汽车的推广普及受到制约和限制。本文大胆提出了依靠汽车行驶中的惯性动能理论利用安装在车轮上的发电机发电的解决方案,它的出现在一定程度上提高了汽车惯性动能能量的利用率,对于克服解决纯电动汽车的动力电池组续航里程和充电难问题有着一定的现实意义。

Utilization Value and Significance of Automobile Kinetic Energy
Zhang Kaijun
Abstract:The automobile industry is one of the key industries that promote the rapid development of my country's national economy. However, with the increase in environmental protection awareness and the appearance of the energy crisis, it has attracted widespread attention from the whole society. As a new energy technology, the research of pure electric vehicles has increasingly become an important way to solve the energy crisis. In recent years, China's new energy vehicles have developed rapidly and have become a bright spot for technological innovation and industrial upgrading. However, the current development and research on battery technology in electric vehicle technology has not found satisfactory solutions in terms of cruising range and charging difficulties, which also restricts the popularization of pure electric vehicles. This article boldly proposes a solution relying on the theory of inertial kinetic energy in vehicle driving and using generators installed on wheels to generate electricity. Its appearance has improved the utilization rate of vehicle inertial kinetic energy to a certain extent, and is useful for overcoming the power of pure electric vehicles. The cruising range and charging difficulty of the battery pack have certain practical significance.

1 燃油車与纯电动汽车的结构区别
那么公知的燃油汽车的行驶依靠的是由发动机、离合器、变速器、传动轴、驱动桥到车轮,最终使汽车行驶起来的。汽车的载荷及速度需要发动机的功率匹配及降速增扭实现的,也就是汽车由静止到行驶起来需要一个过程,这个过程也是汽车行驶阻力最大和油耗最高的阶段,但是随着车速的提高行驶阻力和油耗都在下降。当然,这与路况与环境有很大的因果关系。道路平坦行驶阻力和油耗都要小,这也是我国大力支持路政基础建设来降低能源消耗的主要原因。……
