Why is China vigorously promoting electric vehicles instead of hybrid vehicles? Obviously hybrid cars are better to use
In China, electric cars are strongly promoted instead of hybrid cars, not because electric cars are better than hybrid cars or anything.
It is more about enabling the automobile industry to achieve so-called "overtaking on corners" and at the same time better control emissions and pollution.
The pure electric route is the most promising for overtaking in corners
Hybrid technology is lagging behind and cannot break through
Friends who are familiar with the automotive industry may understand that traditional internal combustion engines The lifeblood of the automobile industry has long been controlled by the world's major powers. It is really more difficult for domestic car companies to break through than to reach the sky.
The simplest example is: Bosch, Continental, Denso and other established companies hold the patented technology tightly in their hands. If we want to use it, we have to pay, and there will be problems if we develop it ourselves, right? ?
In addition to patent restrictions, our own technology is relatively backward because it started relatively late. It will be difficult to break through in the short term. It is almost good to keep up.
An example of hybrid technology: Toyota mass-produced the hybrid Prius in 1997, and China was more than 10 years late in researching hybrid technology.
For example: the 2009 Changan Jiexun hybrid version is considered the first hybrid car in China.
Moreover, hybridization cannot bypass core components such as the engine.
I also talked about this in my previous video "The principle of the engine is so simple, why can't domestic manufacturers make top-notch ones".
Due to weak technological research and development capabilities, technological innovation system and overall industrial foundation, it is still very difficult for domestic car companies to build engines that are comparable to the international first-tier engines.
Pure electric vehicles basically compete fairly for everyone
However, if we take the path of pure electric vehicles, there will not be many patent restrictions, and it will be relatively simple to build a car. The automobile industry wants to " "Overtaking on a curve", the possibility will be greater.
Just kidding, if you install a battery and a motor, the electric car will basically be over there, right? It is much simpler than things like engines and gearboxes.
And to start with, batteries and motors are relatively new, and there is still the CATL era in China, right? Domestic companies are indeed not lagging behind the world level in electric vehicle-related technologies.
The "China Discipline Inspection and Supervision News" had a report in September 2021.
The core components such as power batteries, drive motors, and electronic control systems involved in new energy vehicles are all emerging fields. The power battery industry chain has international advantages, and the drive motors are basically equivalent to the international advanced level. .
In other words: The new track is a fair competition for everyone. Now that we still have a small advantage, the hope of a comeback will naturally be greater.
For example: everyone has just entered elementary school, and the basics are similar. The quality of academic performance depends entirely on one's own hard work. The relationship with the family is not particularly good, and whether the family has money It may not even work.
Energy security is guaranteed
In addition, taking the pure electric route is also due to considerations of future energy security issues.
Dependent on imported petroleum resources
Hybrid cars and gasoline cars have to be refueled no matter what. China still relies on imports for most of its petroleum.
The China National Petroleum Corporation Economic and Technological Research Institute released a "2019 Domestic and Foreign Oil and Gas Industry Development Report", it said.
In 2019, my country’s foreign dependence on crude oil was 72.5%, more than half of that. The foreign dependence on oil was 70.8%. Energy security risks are relatively high.
To put it simply: If you encounter any special problems, such as transportation failure, unwillingness to sell to you, etc., big problems will arise.
There is a lot of coal, mainly thermal power generation
However, looking at it conversely, although our country does not have much oil, as a country with a large coal supply, the guarantee of electricity is much higher than that of oil.
The National Bureau of Statistics has data: The power generation in 2020 will be 7,779.06 billion kW·h, of which 68.52% comes from thermal power generation, and the main energy source of thermal power generation is coal.
In addition, the proportion of clean electricity production such as hydropower, nuclear power, wind power, solar power, etc. is also increasing year by year.
Therefore, it is safe to take the pure electric route.
Able to focus on environmental pollution issues
Hybrid vehicles cause less pollution than electric vehicles
Finally, many friends think that choosing pure electric vehicles must be more environmentally friendly , supports environmental protection. Judging from the current situation, the pollution caused by hybrid vehicles is probably less than that of electric vehicles.
Our country now mainly relies on thermal power generation, so electricity consumption actually transfers pollution to power plants.
So, don’t think that using electric vehicles is necessarily environmentally friendly, it’s not necessarily so. But what is certain? It is the country’s energy security. We want to use it without asking for help. This is very important.
We have also mentioned in previous videos that in 2018, every 1km of electricity consumed by an electric vehicle will basically bring 0.007g of PM solid particles to the power plant. For a gasoline vehicle driven 1km, the emissions will be about 0.005 g.
So, compared with gasoline vehicles, the equivalent pollution of electric vehicles may not be able to widen the gap now. Only when clean electric energy becomes available in the future will there be a positive correlation. Environmental benefits.
But the pollution caused by power generation can be rectified centrally
So, you see, technology is also constantly improving, and the amount of pollution from thermal power generation is really decreasing year by year, and The degree of reduction is relatively large, and it does not mean that we will wait until 50 years later.
The China Electricity Council released the "China Electric Power Industry Annual Development Report 2021".
Compared with 2018, smoke pollution has decreased by 46.7%. You see, it is all cut in half. Sulfur dioxide has decreased by 38.5% and nitrogen oxides have decreased by 28.4%.
Furthermore, although power plants pollute relatively much, they are generally built in places with few people, not in cities where everyone is sucking them in, making it easier to centralize management.
On the other hand, hybrid cars, unless the car is used as pure electricity, just plug it in and charge it, and no oil is added at all.
Otherwise, as long as the engine is working, emissions will still be produced, and the amount of pollution will not be easy to control, right?
Considerations at the strategic level of the automobile industry and energy security
So, generally speaking, the country strongly promotes electric vehicles rather than hybrid vehicles. This does not mean that pure electric vehicles are necessarily better than hybrid vehicles. Movement is more reasonable and advanced.
What is more? Considering the national strategic level, the automobile industry must overtake others, and energy security does not depend on others.
And this thing itself is mature, reliable, and easy to use, and we may even be able to run ahead of others.
