·The electric vehicle technology plan announced the direction of "pure electric drive"

During the "Twelfth Five-Year Plan" period, the development direction of China's electric vehicles has finally become clear, and "pure electric drive" will become the development direction of China's new energy vehicle technology. Among them, a series of technologies such as batteries, motors, and electronic control are waiting to be developed.

A few days ago, Science and Technology Daily was authorized to issue the "12th Five-Year Plan" (Abstract) for the development of electric vehicle technology.

"Pure electric drive" technology route is clear

On the technical route, the "Planning" clearly pointed out that from the perspective of cultivating strategic emerging industries, the development of "pure electric drive" electric vehicles with relatively high degree of electrification is the development direction and top priority of China's new energy vehicle technology. It is necessary to plan the development strategy of electric vehicle technology under the guidance of the overall principle of parallel interaction and common development of “transition and transformation” of energy conservation and new energy vehicles.

The reporter learned that on the technical route, in the near future (2010-2015), the application of hybrid technology will be promoted as soon as possible, and small pure electric vehicles and plug-in hybrid electric vehicles will be developed; medium-term (2015-2020) will be in hybrid power. On the basis of widespread application of technology, the promotion of small pure electric vehicles and plug-in hybrid vehicles will be strengthened; after 2020, pure electric drive technology will gradually occupy a dominant position, through the development of pure electric vehicles and fuel cell vehicles. Significantly reduce emissions.

To this end, during the "Twelfth Five-Year Plan" period, China's electric vehicles will establish a "pure electric drive" technology transformation strategy, give play to China's favorable conditions and comparative advantages, and implement the automobile industry technology transformation strategy for "pure electric drive" to accelerate development. Pure electric drive" electric car products.

Specifically, during the “Twelfth Five-Year Plan” period, the development of electric vehicles in China will give priority to the development of “pure electric drive” electric vehicles in urban public vehicles and private small cars, and start large-scale market; then roll development and gradually squeeze the middle and high-end This market space for fuel cars.

Lithium battery will achieve industrial breakthrough

In the key tasks of science and technology innovation during the "Twelfth Five-Year Plan" period, "Planning" pointed out that it is necessary to firmly grasp the strategic transformation direction of electrification of automotive power systems, focusing on breakthroughs in key core technologies such as batteries, motors, and electronic controls, as well as electric vehicles. Key technology and commercial bottlenecks.

The "Planning" proposes to use the power battery module as the core to realize the large-scale industrialization breakthrough of the vehicle power battery focusing on energy-type lithium-ion power batteries in China. "Planning" calls for the development of modular technology for power batteries, and the localization of key materials; the establishment of automated production lines with power battery modules as the core; the standardization, serialization and generalization of vehicle power battery modules to support pure electric drive electric The commercial operation mode of the car provides protection.

In terms of motors, the “Planning” requires the development of hybrid engine/motor assembly and electromechanical coupling transmission assembly for the large-scale industrialization of hybrid power, forming a series of products and market competitiveness, and providing large-scale industrialization of hybrid vehicles. Technical Support.

In the field of electronic control, "Planning" proposes to focus on the development of advanced pure electric drive vehicle distributed, high fault tolerance and strong real-time control system, efficient, intelligent and low noise motorized assembly control system, electric vehicle vehicle information, intelligent charging And its remote monitoring technology to meet the needs of large-scale demonstration of pure electric vehicles.

In addition to the above three core technologies, the “Planning” also proposes to build a networked power supply system consisting of 400,000 charging piles and 2,000 charging and replacing stations in more than 20 demonstration cities and surrounding areas by 2015. Large-scale commercialization of electric vehicles demonstrates energy supply needs.
