What are the main problems in the research and development process of new energy vehicles in China?

First, lack of core technology

As an emerging industry, new energy vehicles have achieved great technological innovation and development compared with traditional vehicles in China, but there are also many shortcomings. New energy vehicles use more advanced technology in the development process, and the production technology is used in the production process.

There are higher requirements. Judging from the current development of new energy vehicles in China, the overall level of new energy vehicles in China is the same as that of Western countries.

There is still a certain gap in comparison. From the performance and quality of the core components, it can be seen that China's scientific research level is the same as that of developed countries.

There is still a certain gap. Therefore, in the process of development, China's new energy vehicles should occupy the international market.

is extremely difficult.

Second, high cost

Compared with China's traditional automobile production technology, the production process of new energy vehicles is not mature enough. In the process of processing and production, new energy vehicles need to use a lot of advanced technologies and processes, which requires a lot of financial support. Moreover, in the development process of new energy vehicles, due to the immaturity of technology, continuous debugging and improvement are required, which may consume a lot of resources.

Due to the production cost of new energy vehicles in the development process.

The higher, they will be much higher in the market. When people choose to buy a car, they will be more inclined to the relatively low traditional Chinese car. This makes it impossible for new energy vehicles to open the domestic market in the development process.

Third, the infrastructure is insufficient

There are many issues that need to be considered in the development of the new energy vehicle industry. In addition to basic raw materials and core technologies, other infrastructure needs to be considered. For example, new energy vehicles need to be charged during use, but according to the current development situation in China, the popularity of new energy vehicles is not enough, and charging piles.

The setting cannot meet the needs of new energy vehicles at this stage. Many new energy vehicle users do not dare to use new energy vehicles for long-distance travel after purchasing new energy vehicles, and charging piles are not installed in some rural areas of China. Most economically underdeveloped areas are still using traditional cars, and new energy vehicles are very rare.

If residents in these areas buy new energy vehicles, in the case of insufficient power, new energy vehicles will become a kind of decoration, seriously affecting residents' travel.

Fourth, insufficient investment

As an emerging industry, new energy vehicles need to invest a lot of money, but the actual situation is that China's investment in new energy vehicles has not increased, and policy support has not been released. Many new energy vehicle companies may slow down the overall pace of development; Due to lack of funds, some companies may even be on the verge of bankruptcy because they cannot afford the high costs. At present, there are not many R&D personnel for new energy vehicles in China.

These reasons have led to the failure of China's new energy vehicle research project.

The existing problem is that the battery capacity of new energy vehicles is not large enough, the quality of new energy vehicles is problematic, the battery life is not long enough, there are some problems in body design, and there are also problems in the promotion of new energy vehicles.

First, the level of scientific research and technology are insufficient. Second, the cost is too high, and the R&D cost invested by reversing enterprises is particularly high, and the third is that the popularity of equipment for charging new energy such as charging piles is very low, and charging is inconvenient.

Lack of core technology, high cost, insufficient infrastructure, insufficient investment, imperfect performance, etc.

The main obstacles facing the development of new energy vehicles at this stage are as follows:

First, there is a lack of advanced technology

Advanced technology is not only the support of emerging industries, but also the most important component of the development of emerging industries. In the promotion and development of new energy vehicles, advanced technical support is first needed. The research on the core technology of new energy vehicles is still in its infancy.

Prior to this, the core technology of western developed countries was introduced. In terms of research, insufficient precipitation affects the development of new energy vehicles. The primary problem of some new energy vehicles in China is that the endurance is insufficient, and there will be power outages during use.

The emergence of these problems directly reflects the lack of advanced technology in the research and development of new energy vehicles.

Second, the infrastructure construction at this stage is not perfect

The construction of China's new energy vehicle infrastructure is not perfect, and this problem is one of the main factors that make it difficult for new energy vehicles to develop smoothly in the actual promotion and development. At this stage, China's cities have not yet established and improved basic equipment such as new energy vehicle charging stations and charging piles.

3. Insufficient market demand and disorderly competition in the industry

China's new energy vehicle industry is still in the early stage of development. The establishment of many equipment and market systems in the market is not perfect, resulting in insufficient market demand and chaotic competition between industries. Judging from the current development of new energy vehicles, some models with the same style and configuration are much higher than traditional petroleum-powered vehicles.

Therefore, this has also become one of the concerns of car buyers. Under the current market economy conditions, the quality of new energy vehicles is the key to determining whether they are welcomed. It is worth noting that in the current market, the state provides many subsidies to support consumers to buy new energy vehicles.

Fourth, the scope of policy benefits is small

In the process of vigorously promoting the new energy vehicle industry, the above-mentioned countries have provided consumers with a series of preferential policies, but the direct beneficiaries of these preferential policies are not the new energy vehicle industry, and the state has not formulated perfect consumer incentive policies. Taking new energy vehicles as an example, the new energy vehicles with the same style and configuration on the market are about 1-2 times that of petroleum-powered vehicles. In this case, if the state cannot supervise or subsidize consumers, it will directly affect the promotion of new energy vehicles in the market.

At present, the main problem is that the charging problem has not been solved, the battery problem has not been solved, the battery life is relatively low, and you can't go far away.

At present, there are still many problems in the development of new energy vehicles, mainly breakthroughs in science and technology. Reducing the car's energy consumption by improving its appearance is key.

The main problem is that charging new energy vehicles is a problem now, and the battery life is relatively short.

1.Cruising range.

The mileage on the car manual and the mileage of the sales consultant are too different from the actual mileage, and the mileage on the manual is the theoretical mileage of the experimental test, but we will encounter various problems in the actual driving process, so the actual range is too different from the original propaganda, for example, when it was said that when it was fully charged, the minimum mileage could reach 300 kilometers, but the actual mileage was 250+ kilometers, especially in the summer, when the air conditioner was turned on, even two 200+ could not run. The cruising range must be effectively increased in order to make the cruising anxiety of consumers or car owners disappear, and this will involve the battery pack and vehicle layout, etc.; The speed of energy supply will be one of the more difficult problems for new energy vehicles to solve.

2.Charging issues.

Electric vehicle. Most of the time is spent charging. When you need to charge temporarily outside, you often have to take a long detour to find a charging pile.

The convenience of charging is far less than that of gasoline cars. In reality, every time before the socks are closed, you have to look at the remaining power and plan it.

Although the total number of new energy vehicles in China has developed to a certain extent, it is far from enough in terms of infrastructure, that is, the popularity of charging piles. At the charging piles in some city centers, you can often see new energy vehicle owners queuing up to charge. In addition, although many charging piles have been built, the later maintenance can almost be called none.

3.Cars** do not retain their value.

Domestic cars. It is relatively unpretentious, not to mention domestic electric vehicles, after all, it is a product with a relatively low degree of recognition now, and now the energy vehicles are bought because of ** and national policies, many places are limited and new energy vehicles are not limited, but wait for car batteries.

After the problem occurs, some people will choose to sell the car because of the problem of the battery, and the car will also consider the ** of the battery, so the price of the car will be very low, resulting in the owner can only entangle himself.

4.After-sales service needs to be strengthened.

Although the structure of electric vehicles is simple, because the power part is far from traditional cars, it will still encounter some troubles in maintenance. The first problem is the lack of maintenance technicians, most of the technicians can repair traditional cars, but lack of knowledge of electrical appliances, rash maintenance of electric vehicles may not only cause damage to the vehicle, but also have a certain degree of danger. The second problem is the scarcity of parts, the production and ownership of electric vehicles are small, so there are few parts, and the first is high.

There are many places that need to be improved, to build more to slow down the charging of which pile, to improve the endurance of new energy vehicles, to improve the cost performance, to improve the quality of products, to pay attention to the safety of dismantling.

Charging problems, mileage, maintenance costs, as well as after-sales service, its safety performance, these problems need to be improved.

In recent years, in the country on new energy.

Under the vigorous promotion of automobiles, some provinces and cities have successively announced the time of banning the sale of fuel vehicles.

At the same time, almost all automobile manufacturers have begun to promote new energy models, and consumers have received new energy vehicles.

The degree of acceptance is also rising. China's new energy vehicles.

The development is still in the critical period of climbing, and there are still many problems in technology, quality and consumer feelings of new energy vehicles that need to be further solved.

First of all, most of China's new energy models, especially pure electric vehicles, have a large range problem, especially in autumn and winter, pure electric vehicles are difficult to survive the winter. China's new energy vehicle safety.

The full performance is poor, and the "three electrics" fail

Problems such as spontaneous combustion occur frequently, causing them to car owners.

was very troubled. At present, China's new energy vehicles.

Public facilities such as charging piles are imperfect and maintain value.

Problems such as low rates also make consumers print on them.

Elephant big discount. In short, our country is new.

The source car only breaks through the battery life, safety,

Problems in charging, value retention rate, etc., can make a qualitative leap.

Although there are still many problems waiting for us to solve, the Ministry of Industry and Information Technology, as a top-level design department, is currently carrying out relevant work from many aspects.

Support for the new energy vehicle industry: First of all, according to the needs of the market, further increase.

high standards and strengthened quality supervision; Secondly, new energy vehicles will be combined with smart roads

Advanced technologies such as communication networks and cloud technology.

to be integrated, and through electrification and intelligence.

The network is further integrated to open up a meeting of consumers.

new features that the fee demands; Thirdly, improve charging, parking and other facilities, and improve public transportation.

the level of electrification; And finally, in technology.

Innovative, international** and even standards and regulations.

In terms of formulation, we have an open and cooperative attitude. This.

These measures are for the development of new energy vehicles in China.

Injected with new impetus. On the whole, China's new energy vehicle industry is still.

It is in the early stage of development, although it has great potential, but it is still a long way from becoming the mainstream of the auto market.

A long way to go.

First of all, the most important thing to solve for new energy vehicles should be the problem of battery life. Then there is the expansion of battery capacity in new energy vehicles. The equipment for charging new energy vehicles is seriously insufficient, and it cannot be equipped all over the country.

The problem of electrolyte optimization in new energy vehicles also needs to be solved.

The battery of new energy vehicles is a bit high, and there are great concerns about battery life, power problems, excessive power consumption caused by heating in winter, and thus a short mileage.

New energy vehicles need to improve their own capabilities, need to improve the battery life, and the overall control of the body is intelligent. These problems are very confusing.

Battery problems, charging problems, driving speed problems, mileage problems, maintenance problems, these are all problems that need to be solved.

On the one hand, the outstanding problems existing in the new energy contract car are the problem of limited mileage, and on the other hand, the problem of insufficient charging piles. These two issues are also the factors that people consider the most when buying new energy vehicles. And to solve these two outstanding problems.

Ways to solve the outstanding problems of new energy vehicles. The first is the adoption of more efficient batteries. Because new energy vehicles use electric energy as power, the energy efficiency of the battery determines the mileage of new energy vehicles, and only the development and use of more energy-efficient batteries can solve the problem of limited mileage of new energy vehicles; Secondly.

The inability to charge in time is also a reason for the lack of battery life of new energy vehicles, and in order to solve the problem of difficult charging of new energy vehicles, it is necessary to build more charging piles, so that new energy vehicles can be charged anytime and anywhere, to ensure the normal operation of new energy vehicles; Finally, the optimization of the system. New energy vehicles are also smart cars, and the operating system of new energy vehicles needs time to be upgraded and stabilized, and then optimized, and only a stable system can make new energy vehicles truly safe, efficient and environmentally friendly.

The energy efficiency of new energy vehicle batteries determines the cruising range of new energy vehicles, and the development of more efficient batteries can effectively solve the problem of limited cruising range of new energy vehicles. <>

New energy vehicles are also intelligent vehicles, and the continuous improvement and optimization of the system of new energy vehicles is an important guarantee to ensure the safe driving of new energy vehicles.
