Bentz and Diamler are recognized as the inventors of Hyundai Motor , which is powered by internal combustion engine . Their inventions and creations have become the most important milestone in the history of automobile development. They are therefore respected by the world as the "father of automobiles ".
Nowadays cars are no longer what they were when they were first produced, and even the driving methods have become more and more. For example, the current electric drive, hydrogen drive, etc., although traditional fuel vehicles have been developing for hundreds of years, they now seem to be in danger for various reasons.
In the early years, due to the improvement of automobile production technology, cars on the road became more visible to the naked eye. According to statistics, in China, has 33 cars in every 100 households, and 4 cars in every 10 households in urban residents have cars. With the increase in car ownership, a series of problems brought about are becoming increasingly prominent. The large amount of exhaust emissions not only causes serious air pollution and the emission of greenhouse gas , but also causes the increasing effect of greenhouse effect . Sea level rise , frequent extreme weather, accelerated melting of glaciers and other bad effects are constantly reminding people that we need to pay attention to the environmental protection around us. So, the new energy vehicle was born.
new energy vehicles refer to the advanced technology of advanced technology, advanced technology, new technology and new structure, using unconventional automotive fuel as the source of power (or using conventional automotive fuel, using new vehicle power devices), integrating advanced technology control and driving of vehicles, and forming an advanced technology, with advanced technology and new structure.
new energy vehicles include four types: hybrid electric vehicle (HEV), pure electric vehicle (BEV, including solar car ), fuel cell electric vehicle (FCEV), other new energy (such as supercapacitor , flywheel and other high-efficiency energy storage devices) cars, etc. Unconventional automotive fuel refers to fuels other than gasoline and diesel.
The more common new energy vehicles are still mainly hybrid and pure electric vehicles. Although all parties are strongly supporting new energy vehicles, the sales of new energy vehicles are also showing a geometric growth. Many traditional car dealers have even announced the sales years of fuel-only selling fuel vehicles and the world of continuing to study internal combustion engines. The market share of of traditional fuel vehicles is also gradually declining, but it has always had a certain share and cannot be shaken for a short period of time. So, why?
New energy vehicles cannot replace fuel vehicles in a short period of time. They are nothing more than the following fatal weaknesses. Let’s take a look at them one by one:
1. Charging time. In the early new energy vehicles, charging problems have always been criticized. At the beginning, the manufacturer's technology was immature, and in order to reduce the heating problem during the charging process, only slow charging was provided. At that time, it took several hours to charge a pure electric car, and even a large number of cars were there for one night. Fortunately, you can directly use the home 220v charging, which is barely acceptable if you slow down. Fortunately, with the current technological progress, many manufacturers have equipped fast charging on their cars. They can be filled in half an hour or even dozens of minutes with charging piles, but it is still far from filling up the fuel in a few minutes of fuel vehicles.
2. Battery life issue. These two problems have always been two long-standing problems for pure electric cars. Today's pure electric cars are basically dominated by ternary lithium or lithium iron phosphate batteries. In contrast, lithium iron phosphate batteries are safe, have a long life and are resistant to high temperatures; ternary lithium batteries are lightweight, have high charging efficiency and are resistant to low temperatures. It can be said that each has its own advantages and disadvantages. Friends who buy pure electric cars must understand clearly in advance and choose cars with different batteries based on whether they are in , , or north.
But no matter which battery it is, the problem of shrinking battery life is a hidden rule in the industry. The average shrinkage in the industry is basically about 60 to 70% marked by the manufacturer, and the shrinkage is even 50%.This problem is like the fuel consumption of the Ministry of Industry and Information Technology. When you are on the road, it is impossible to escape the manufacturer's battery life. Because when testing the battery life, the electrical appliances on the car were turned off in the laboratory and drove at a constant speed. When actually running on the road, not only would various electrical appliances be used, but they would also accelerate, decelerate, change lane, etc., so the battery life was greatly reduced. In addition, the electrical appliances of fuel vehicles can be powered by batteries, and heating does not require additional fuel consumption. However, trams are different. Whether it is radio, central control, heating and cooling, any electrical appliances cannot be separated from the power battery life of the entire vehicle, so there are many cases of greatly reducing the battery life in actual use. In addition, when driving at high speeds, fuel vehicles are the most fuel-efficient, but after the tram exceeds 80 hours, the battery life is actually reduced, which is also the reason why pure trams are difficult to adapt to long-range driving.
3. Security reasons. In recent years, due to the popularity of pure electric vehicles, cases of fire have also been common. When a pure tram experiences violent collisions, the battery can easily be pierced by debris on the car, causing an explosion or fire. In response to this, BYD also specially developed blade battery , but the spontaneous combustion problem still cannot be solved from the root. Many trams even drive well and suddenly catch fire, or park in parking lots. There are many fires caused by high temperatures and charging reasons. This is also one of the reasons why pure trams are discouraging consumers to withdraw.
Although the technology of pure electric vehicles is not yet fully mature, the sales of new energy vehicles are increasing today. It is reported that data from the Passenger Car Association showed that in October, the retail volume of the fuel vehicle market was 1.28 million units, a year-on-year decrease of 8%, reversing the positive growth trend of 's year-on-year growth of 6% from June to September this year. The cumulative retail volume from January to October was 12.28 million units, a year-on-year decrease of 13%. On the other hand, new energy vehicles: the development momentum of new energy vehicles in in October is still rapid, and new energy vehicles hit record highs in succession and gradually became a trend. In October, the production and sales of new energy vehicles reached 762,000 and 714,000 respectively, and the year-on-year increase of to 87.6% and 81.7% respectively, with a market share of 28.5%; from January to October, the production and sales of new energy vehicles reached 5.485 million and 5.28 million respectively, a year-on-year increase of 1.1 times, and the market share reached 24%.
Even if the sales of new energy vehicles have not exceeded that of fuel vehicles, there are signs of coming from behind. Thanks to the dual-carbon policy promoted in recent years, and electric vehicles have advantages that cannot be exceeded by fuel vehicles, such as acceleration and daily maintenance costs, more and more consumers are beginning to choose new energy vehicles. In view of the above shortcomings, the market has also launched hydrogen energy vehicles powered by hydrogen. However, due to factors such as hydrogen production and hydrogen storage, the hydrogen energy vehicles have not been vigorously promoted. In addition, there are more niche cars for solar cars.
In short, whether from the development of science and technology or from the consideration of environmental protection, the comprehensive replacement of fuel vehicles in new energy will be an inevitable trend in the future. However, because fuel vehicles have been developing for a long time and have accumulated enough technology, they will not withdraw from the stage of history for a while. Fuel vehicles are like middle-aged people. Although there are accumulations, they will eventually be given up on the stage; new energy vehicles are like young people who have just stepped on the stage, slightly immature, but they have countless possibilities.
has less time left for fuel vehicles, which makes people ask: Lian Po is old, can he still have a living?
