The China New Energy Vehicle Development Summit Forum hosted by China Automotive News and the China Automotive Engineering Society, organized by Tianneng Battery Group and Automotive Network, was held in Shanghai on May 28, 2010. Government decision-making and leadership departments, automobile manufacturers, power battery companies, research institutions, universities, associations, and industry experts conducted in-depth exchanges and discussions on hot topics such as the demonstration and promotion of new energy vehicles, technology development, and commercialization experience. Beijing University of Technology’s deputy director of the National Electric Vehicle Engineering Laboratory and the director of the National 863 Electric Vehicle Major Project, Lin Cheng, said at the New Energy Vehicle Development Summit Forum that pure electric vehicles can be developed into electric passenger cars and electric commercial vehicles, and pure electric vehicles can be developed. Commercial vehicles are an entrance.
According to Lin Cheng, the priority is to develop a purely electric city commercial vehicle because of its ability to conduct fixed-point operation, centralized charging and balancing of power grids, and development of autonomous technologies.
Lin Cheng also pointed out that if pure electric commercial vehicles want to do better, they must also make progress in several aspects. For example, the structure of the vehicle, the use of high-efficiency drive motors and transmission systems, to improve the standardization of the battery; the application of electric vehicle commercial vehicles also need to be improved, electric vehicles and other drive vehicles are not the same, there is no existing gas station, in addition to In addition to the vehicle technology, the infrastructure must be completed; the rapid battery replacement system also requires research and development, and battery charging stations that try their best to quickly replace the battery. It is better to abandon the vehicle charging scheme and realize the charging in the bin. The high cost of the battery has led to the adoption of the lease model, which will spread the cost of the battery into operation.
Compared with pure electric commercial vehicles, passenger car technology faces greater challenges. The control strategy for passenger cars is complex. The technical requirements for batteries, motors, and vehicles are even higher, and the overall layout is also more compact. At the same time, pure-electric passenger cars also require comfort, intelligence, safety, and reliability. Taking electric commercial vehicles as a breakthrough point and doing as much as possible to promote the development of parts and components can provide experience and foundation for the development of pure electric passenger vehicles.
“Electric passenger cars and electric cars are the goals of the new energy industry in the future and their ultimate destination,†Lin Cheng said.
Double Girder Overhead Crane With Hoist
Double Girder Overhead Crane with dual hoists means two hoists share the same girder,cabinet,festoon cable and other Crane Parts.The larger tonnage Hoist also called main hoist,the smaller tonnage hoist also called auxiliary hoist can be operated synchronously or independently.It greatly saves the space and cost, as well as improve the efficiency of Overhead Crane.Eurocrane overhead crane adopts European concept ,has the features of superior performance,compact structure,small dimension of headroom and makingfull use of available space of the plant. In addition the design of the product has fully considered the requirements of customers to increase the safety and easiness during the use. The standard configuration includes trolley frequency conversion and cart frequency conversion to make the running stable and reliable.
