Advantages and disadvantages of new energy electric vehicles
1. Advantages of new energy vehicles:
1, saving fuel and energy. Generally, it is powered by natural gas, liquefied petroleum gas, hydrogen and electricity.
Reduce exhaust emissions and effectively protect the environment. Electric vehicles do not produce tail gas and are pollution-free. No pollution to the environment. Because it is basically zero emission, it is also outside the limit range. 3. High efficiency. Generally speaking, new energy vehicles adopt new technologies and new structures to make them more efficient. 4. Low noise.
Second, the shortcomings of new energy vehicles:
1, because new energy vehicles are in the initial stage and the technology is not very mature. So charging is very slow and takes several hours.
2, the number of vehicles is small, and charging, refueling and maintenance are inconvenient. Moreover, the popularity of new energy vehicles is small and charging is difficult.
3, the cruising range is short. General vehicles have small displacement and insufficient power, which is not suitable for long-distance driving.
The price is not low. At present, only pure electric vehicles have low-cost new energy vehicles for mass production, and the selectivity is not too great.
Price analysis of new energy electric vehicles
It is hard to say how much electric new energy vehicles will cost in the future, but as far as the mainstream brands on the market are concerned, there are as low as 30,000-50,000, and as high as 700,000-800,000, and the popular models are more than 200,000-350,000. For mainstream brands, there are BYD and Tesla. SAIC-GM-Wuling, Weilai, Tucki, Ideality, etc.
Not only that, but the configuration of different models of the same brand will also be different. Judging from the mainstream brands in the market, the guiding prices of some models are as follows: It is hard to say whether the price of new energy vehicles will be reduced in the future, but so far, the prices of new energy vehicles have gradually increased. It is not difficult to see that there are a lot of rare metals in automobile batteries, and the price of rare metals has been high.
The new energy vehicle has been sold for 6.5438+0.5 million yuan a ton before the fire. Now, the price of rare metals has reached about 600,000 yuan a ton. The rise in the price of raw materials will inevitably lead to the rise in the price of automobiles.
But then again, the price of new energy vehicles is now high, and the subsidy policy for car purchase is only extended to the end of 2022, and it will be completely cancelled in 2023. Now that there are subsidies, there are still many people who are unwilling to buy them. If there was no subsidy at that time and the price remained high, it would be difficult for new energy vehicles to form a competitive advantage with fuel vehicles in terms of price. As for the details, let's wait and see.
What is the significance of developing new energy vehicles?
New energy vehicles are the development direction of the future automobile industry: it is of great significance to develop new energy vehicles.
1, environmental significance
The global environment in which we live is deteriorating. Global warming, accelerated extinction of species, climate change and melting of polar glaciers have led to rising sea levels, which has led to traditional plans to ban the sale of fuel vehicles.
2, the significance of technological innovation
Traditional fuel vehicles have been developed for hundreds of years, and the technology is very mature. The research and development of engine, gearbox and other core components is close to the technical bottleneck, and it is difficult to make any breakthrough.
Compared with traditional fuel vehicles, new energy vehicles have more room for technical development, and the comprehensive efficiency of motors and motor controllers can reach 90%, which has room for improvement. Battery technology is also improving year by year. The cruising range of new energy vehicles is getting longer and longer, and the charging time is getting shorter and shorter.
3. Practical significance
Due to the characteristics of the motor, new energy vehicles can provide drivers and passengers with a more stable and comfortable driving experience. In addition, in the direction of electrification, integration and intelligence, new energy vehicles have more room for development than fuel vehicles and are more practical.
