The electric car is nowadays one of the most 'hot' products, the world famous automobile manufacturers are struggling to compete for the 'novelty', of course the domestic enterprise also unwilling to lag behind, and the electric vehicle in the process of equipping the stand or fall of motor and directly determines the performance of high and low, the electric car industry development in our country and foreign gap is widening, the motor gap is particularly obvious. Due to the development of new energy vehicles, pure electric car motor used in the market has become a key sales direction, although many domestic companies claim to have the whole industry chain's scientific research strength, but must be a really good motor need long-term technical accumulation, and then to manufacture, test, and eventually go in mass production. Domestic real power of the new energy motor vehicle companies rarely, especially in the field of passenger cars, in various enterprises under the background of vigorously promote has a core of independent, everyone don't want to shows as one of new energy vehicles core components of the motor link is still in the future. In China claims to be doing a lot of enterprise of new energy motor, but professional do new energy motor companies rarely, a lot of enterprises from the traditional field of machinery, shipbuilding and other traditional industrial motor turned into the new energy field of drive motor, few research and development, production experience. Although the traditional industrial motor and new energy vehicles are interlinked in principle, but there are still not on the actual manufacturing district. New energy vehicles used motor can be divided into two kinds of induction motor and permanent magnet motor, the former is mainly used for public transport, passenger and commercial vehicles, while the latter is mainly used in passenger cars. As a result of the asynchronous motor rotor winding, also no brush, no induction, power conversion efficiency is low, construction is simple, the price is cheaper also, mainly used in large passenger cars; Motor and permanent magnet motor rotor winding, brush to the rotor power supply, power conversion efficiency is big, complicated structure, the price is expensive, it is mainly used for harsh environment to speed requirement, such as pure electric passenger cars. In the process, a lot of form a complete set of motor companies are on rush and simple technical improvement on the traditional industrial motor, as a new energy automobile motor provides oems. But in foreign countries, there are a number of strict production of new energy automobile motor technical indicators. New energy vehicles, especially pure electric vehicles is uphill, downhill, flat surface, bumpy road at different road conditions, such as, is not the same as the output power of the motor. Many domestic motor factory is only slightly on the production experience in traditional industrial motor improvement, no considering the use environment, new energy automobile motor will greatly shorten the service life, and easy to cause local overheating and short circuit and other dangerous situations. Since both realized that the electric car motor will have broad market in the future, why not strictly from the research, development, test and production of motor to control, for basic research as soon as possible, 'calm down' starting from scratch, truly form the electric car motor industry chain, with a sound attitude in the face of handy opportunity. As the necessary energy storage equipment in new energy vehicles, power battery will play a key role. Lead-acid battery power. The development of new energy vehicles puts forward high demand on power battery, power battery research and development and production of high-performance advanced gradually developed, including lithium ion power battery, new high capacity of lead-acid batteries. 'High performance power battery is an important technology of the development of new energy automotive industry support. 'Huang, institute of physics, Chinese Academy of Sciences, told reporters. , he thought, enhance the technical level of the power battery industry, establish industrial generic technology development platform, can with the battery industry development direction and key enterprise needs, the combination of solve the problem of battery production technical bottlenecks and process. In ascension, on the basis of battery, motor and other core components, the competitiveness of the industry system is expected to improve, and promote the new energy vehicles in China in 2012 to promote faster.
