With the problem of air pollution and the growing oil shortage, the use of hybrid and electric vehicles instead of traditional gasoline and diesel vehicles have become the issue before the people. Governments around the world are pushing for hybrid / electric vehicle research. The U.S. government has announced that 2.4 billion expenditure to finance the battery pack, motor and other parts of the new design, and development of the road in a 2015 goal of 1 million hybrid vehicles. U.S. Department of Energy predicts that by 2030, the light of new energy vehicles will account for 28% of car and truck market share, which increased by 20% compared to 2005.
Calling a new generation of power transmission system
To satisfy the hybrid / electric vehicles growing demand, R & D performance better, more affordable electrical transmission system in an increasingly competitive. ANSYS Mechanical and Electrical Products Technical Director, Mr. Scott Stanton, said in an interview, "the development of new electric transmission system has tremendous potential for commercial returns, but at the same time, there will be flawed, not suitable for the market, it is not perfect product push to the market there are commercial risks. "
Clearly, the automotive technology is undergoing a revolution. The important task of leading this revolution has landed on the shoulders of Automotive Engineers, they must rethink how to powertrain design. Both the vehicle manufacturers or parts manufacturers engineers engineers are faced with the challenge of how, in a very limited period of time, developed a new generation of power transmission.
To meet these needs, with a hybrid / electric car innovation of the major car companies to concentrate on the development of simulation-driven, rather than outdated prototype test repeated. "In fact, the next generation of electric drive systems in the design competition, the ability to effective implementation of advanced numerical simulation technology may be good at it, winners and non-competitors to distinguish." Scott Stanton said.
Scott Stanton believes that there are many software solutions for power system development in a variety of performance analysis, including mechanical analysis, electrical analysis, electromagnetic analysis, electrochemical analysis, fluid analysis, thermal management applications in analysis. "Typically, these independent analysis software can not completely compatible, thus impeding the engineer to fully and effectively to achieve optimum design of electrical transmission system."
Advanced engineering simulation technology can not only help engineers in-depth examination of complex components and system performance, but also through virtual prototype design and testing, to speed up and improve the powertrain research and development. Scott Stanton said, "ANSYS simulation technology can help manufacturing engineers in the prototype prior to the understanding of the system performance under various conditions. This advanced CAE technology will help manufacturers in the traditional powertrain technology competition. "
Electric and hybrid electric vehicle powertrain is a very complex system, its systems, subsystems and components must be coherent and closely with the run, in order to ensure the efficiency and performance cars optimization.
Telecommunications systems in the car with an integrated simulation platform, accurate simulation, developers can evaluate each of the above components, subsystems and system machine interaction between them. As in the real environment, the components will be affected by the impact of multiple physical domains, so the simulation tool must be able to accurately predict the impact of various external to it, including structural mechanics, dynamics, fluid dynamics, thermal physics, electromagnetism, electrochemistry, electromagnetic radiation and electromagnetic interference / electromagnetic compatibility and so on. Meanwhile, the power transmission system design must be able to handle these complex model of a reduced order model parts and use them to create a system and subsystem models, and ultimately to optimize the subsystem or the entire electric drive system performance.

Low-emission new energy vehicles, the task is not long way to go carbon zero emissions
In the new energy vehicles is the general trend in the background, the auto companies regardless of size, in no particular order, have their own way according to a new energy car project launched; traditional energy infrastructure giant has also opened up a new battlefield, the State Grid, China Southern Power, Sinopec and CNOOC to invest heavily in major cities in the country charging station business.
However, the problem can not be ignored is that although the pure electric vehicles can travel stage zero emissions, but its consumption of electricity, and the reserve power batteries used in the production process of carbon emissions may be better than conventional vehicles is low.
Fossil fuel electric cars
Define whether a car or zero carbon emissions, carbon emissions should be calculated the sum of it, including car design, parts and vehicle production, and vehicle recovery and other aspects of the sum of carbon emissions.
To pure electric vehicles, the zero-emission process should include a complete, only used for electric vehicle batteries from lithium materials, to provide electricity for electric vehicles and all other aspects of the power plants do not emit carbon dioxide, electric cars can really be said to be zero emissions.
Pure electric vehicles in motion the process to power as an energy source does not emit carbon dioxide. Compared to conventional gasoline cars, do the driving stage to achieve zero emissions. However, as the electric vehicle energy sources of electricity in the production process is hard to avoid carbon emissions.
The current model of China's major thermal power generation, accounting for nearly 80% of total electricity generation. The thermal energy is the major coal and oil, both of the production process will result in carbon emissions.
It is understood that, in accordance with the current technology, pure electric vehicles 100 km average consumption of about 15 degrees, if the full use of coal as fuel, which is usually the case in the power generation process will produce about 14 kg of carbon dioxide that is driving hundreds of pure electric vehicles km of carbon emissions to 14 kg. And a hundred kilometers to 4L of small cars burning gasoline required to travel 100 km will produce about 10 kilograms of carbon dioxide. So the whole, the carbon emissions of new energy vehicles may be higher than traditional energy vehicles.
