(2) The main problems of the development of hybrid vehicles in my country and the gap with foreign countries. The overall vehicle is still in the prototype stage. Without multiple rounds of verification research, the system optimization and batch production requirements have not been met; the component industry chain has not been formed, and key raw materials and electric electronic components rely on imports; The product is still in the early stages of industrialization and the cost is high.

(3) The main problems of the development of fuel cell vehicles in my country and the gap with foreign countries. In terms of core technologies, such as the technical level of fuel cell pile and engine system, there is a large gap between foreign countries (obviously behind Honda, Toyota, Ballard, GM), and the technological research and development progress is relatively slow; The problems of hydrogen and hydrogen energy infrastructure have not been resolved; there is still a large gap between the reliability and cost of the product.

(4) problems existing in key technologies of new energy vehicles. First, in terms of battery materials, the stability of lithium iron phosphate material has poor batch stability, and there is differences in conductivity. The industrialization of domestic power battery septum is still at time. Hydrogen storage materials and nickel hydroxide cannot fully meet the requirements of the power battery, and need to be treated later. The second is that in terms of battery and its group technology, the yield rate of lithium iron phosphate battery has a low yield and high cost. Power battery products are not consistent. Battery and materials production equipment manufacturers have weak research and development and manufacturing capabilities. The battery management system has a simple function, poor performance, and poor product reliability.

Some materials and components have weak research and development capabilities in the technology of vehicle -driven motor, and key components rely on imports. The product performance is still gapd from foreign countries. The main problems include: one is that the R & D capacity of motor raw materials and components is weak. There is a gap. The electromagnetic wire insulation performance is large and the foreign abroad is large, the production capacity is weak, the electric motor high -speed bearings depend on import, and the fast connection is connected to the import of plug -in. Core components mainly depend on imports, with higher costs, affecting my country's electric vehicle industrialization.

At present, the volume and weight of the motor controller are relatively large, the level of manufacturing process is backward, the product reliability and consistency are poor, the level of electromagnetic compatibility of the product needs to be increased, the industrialization scale is small, the cost is higher, and the standard for the driving motor system needs to be improved.

3. Countermeasures and measures to develop the new energy vehicle industry in my country

1. Strengthen government guidance and improve policy support

The development of new energy vehicles is a long -term and sustainable industrial strategy in my country. It requires the government departments to strengthen the construction of the supporting service system and create a good internal and external environment that is good for new energy vehicles.

(1) We must give full play to the government's guiding role. By guiding the listing of new energy vehicle companies, broaden financing channels and absorb private capital, thereby promoting its industrialization process. It is also necessary to further improve the construction of new energy vehicle supporting infrastructure and create a commercial atmosphere that is conducive to the development and promotion of new energy vehicles.

(2) Continue to introduce relevant preferential policies. The leading industry and related industrial construction projects of the new energy vehicle industry can be exempted from local administrative taxes and fees in basic construction; for the newly introduced new energy vehicle industry leading enterprises, they can fully support enterprises through loan discounts and technology investment. Accelerate development and growth.
