美国作业代写：Charging and battery problems for electric vehicles

下面为大家整理一篇优秀的essay代写范文- Charging and battery problems for electric vehicles，供大家参考学习，这篇论文讨论了电动汽车的充电和电池问题。如今，电动汽车除设计制造以外，还有诸多问题需要解决。比如电池性能和充电问题，这些都严重影响电动汽车技术的发展和使用。对于电池，我们必须要改进它，让它达到电动汽车持续技术进步的水平。而充电设施，我们必须提高它的性能和质量，以满足电动汽车的使用。

A few days ago, a seminar on electric vehicle Power Battery Systems was held. It is found that there are many problems to be solved in addition to the design and manufacture of electric vehicles. For example, the battery performance characteristics, the design and manufacture of battery pack system, the quality and reliability of charging equipment, charging facilities are not occupied and easy to use problems, charging interconnection and easy to pay problems, and so on. These are all affecting the development and use of the serious electric vehicle technology.

In fact, the same problem exists all over the world. But the attitude towards these problems, the international large-scale automobile production enterprises, and domestic electric vehicle manufacturers are very different. The main difference is that the main way for the world's big auto companies to solve the problem is not to rely on, wait, not to complain, but also to do.

The first is about the battery. At the current stage, most of the world's major automobile manufacturers do not produce power batteries, but have built a large laboratory of power batteries to conduct very rigorous and systematic testing, before the decision to formally use at least one years before the full test evaluation. The basic characteristics and basic rules of the battery are mastered by the test, and the basic characteristics are selected to meet the requirements of the whole vehicle, and the design of electric vehicles is developed. I think this is necessary. For the power battery, we need to know it like the traditional engine, in order to give full play to its performance, design and manufacture the electric vehicle to meet people's travel requirements as far as possible; in the future, we need to improve it as we do with the traditional engine to achieve the requirement of continuous technological progress.

The second is battery pack and management system. Battery pack and its management system is very important to the overall performance of EV, especially the function safety, open Autosar and core algorithm of BMS, which is the key to develop a good battery pack and management system to at least three experts in the field of vehicle, battery and software. The strategy of the world's largest companies is to own the development of these technologies, rather than simply relying on battery manufacturers, the battery production enterprise development and production of a battery pack management system provided to the entire depot to use. On the face of it, there seems to be no problem. The traditional automobile manufacturing enterprise turns to the electric vehicle development, the production, because of oneself in the battery pack system Aspect Technical Foundation is weak, therefore relies more to understand the battery battery production enterprise, should be taken for granted. But there are two major questions: first, battery manufacturers know little about the car's performance requirements, although they understand the battery. Their development of battery pack system is very difficult to achieve both the power battery characteristics, and fully meet the requirements of automotive use of the realm. Of course, power batteries and cars due to electric cars, and should learn from each other. But the complexity of the two is different. In time, car manufacturers can fully understand and skillfully grasp the power battery, and vice versa will be much more difficult. Second, the battery pack system is the important assembly in the automobile big system, should according to the automobile parts quality and the reliability request to manufacture, must according to the function safety process development, rather than according to the Power battery industry to the consumer electron request to develop, the production automobile battery pack system.

The third is about charging facilities. Now domestic electric car manufacturers, the general sense of charging facilities do not reach the needs of the car performance and quality requirements. This is a fact, but also a bottleneck for the development and popularization of electric vehicles. As a new industry formed by the development of electric vehicles, there are many problems in the manufacture and operation of charging equipment, which is an indisputable fact. The author also serves as the chairman of the China Electric Vehicle charging Infrastructure Promotion Alliance which is under construction, knowing the problems and difficulties, and knowing the founder to work hard. In the author's opinion, charging facilities do not meet the requirements of a very important reason is that the whole vehicle enterprises in the development of standard standards of charging process, not enough, the battery and charge gun, pile on the charging performance, quality of the impact of too little. In this regard to the automotive industry recommendations, suggested that the automotive industry to the production of charging facilities as the automotive industry, parts and components industry. The automotive industry should actively participate in the standards of charging facilities and research, testing, development, manufacturing, to the automotive industry's precision, quality requirements into the charging facility manufacturing industry. Of course, I would like to see the traditional automobile industry parts manufacturing enterprises to participate in charging facilities manufacturing, traditional automotive services companies to participate in the operation of charging facilities. This is not superfluous, excessive requirements, because the market is unreasonable, whether it is the car, gun, pile what reason, as long as bad use, the car will not sell out.

This blog is titled Extra Work, in fact, the author of the original intention that all these, are the automotive industry, in particular, electric vehicle manufacturers should do a good job. This is the law of industrial development. In the development of new industries and the emerging fields of traditional industries, the leading sub industries and enterprises always need to develop in addition to their own development, but also to promote the development of related industries and industries, and to facilitate the formation of good industrial ecology. But China's auto industry has been in a state of catch-up, has not yet seen the glory of the leading, but also difficult to recognize the leading responsibility.
