A blizzard stopped the hearts of tens of millions of people who wanted to go home for the New Year, and many "car strong" popped up all over the country in time.
Many vehicles were torn apart due to crashes caused by heavy snowfall, but they hurriedly wrapped a few sections of duct tape and continued on the road.
More vehicles were blocked on the road due to heavy snowfall, and they had to sit dry and freeze.
According to the owners of new energy vehicles, even if the tram does not start or start, it continues to lose powerSome people ran out of power and had to get out of the cart.
Since the staying power of new energy is so poor, why is the new energy group gradually growing? Someone suddenly solved this puzzle as soon as he settled the accounts after three years of new energy.
For nearly 100 years, gasoline vehicles have firmly dominated the automotive marketHowever, due to its high pollution and the non-renewable nature of the fuel, the transition to new energy sources is the general trend.
In the 80s of the last century, Japanese automobiles were sweeping the automobile market all over the world, but Japan had a premonition that new energy vehicles were about to become popular, so they decided to pre-develop new energy vehicles.
It is said that at that time, Japan did not see electricity at all, and considered it an obsolete product, so it did its best to bet on hydrogen energy.
Compared with electricity, hydrogen energy has less changes to vehicles, Japan can complete industrial upgrading at a lower cost, and hydrogen energy is less polluting to the environment than electricity.
Japan has given it a go, and at the same time has registered almost all the core technology patentsIf latecomers follow suit and make hydrogen energy, Japan will be able to eat enough even if it is just a patent fee.
Unexpectedly, China and the United States directly bypassed hydrogen energy, turned their heads to vigorously research and development of electric energy, and gradually solved the problem of charging speed and power, and Japan determined that hydrogen energy was really abandoned by the world.
Japan woke up from a dream at this time, but it was too late, so a few days ago, Akio Toyoda bombarded electric cars.
This can't help but make people wonder, is hydrogen energy more suitable than electricity as a new energy option?
Hydrogen energy is an efficient and clean energy source, which is stronger and more direct than electric energy, and the power is greatly strengthenedBut hydrogen energy has several problems that cannot be solved.
Hydrogen atoms are the smallest in the periodic table, which makes it impossible for a high-pressure airtight tank to prevent a portion of hydrogen from flowing through the structural gaps.
The high-pressure airtight tank on the general vehicle is made of steel, and there is room for hydrogen refueling stations in consideration of safety issues.
The pressure given by each hydrogen refueling station is different, and how long hydrogen energy can run depends entirely on how strong the pressure of the hydrogen refueling station is, which also means that the vehicle carries an explosive product.
However, most cities in China now have underground garages, and hydrogen energy needs to be placed in the open air, otherwise if something happens, it will be a fireball that will sweep the entire garageThis is also the biggest problem that hydrogen energy needs to solve right now.
In addition, the technology for transporting hydrogen has not yet been solved, and the mileage loss of hydrogen energy after winter is no less than that of electric cars, and the technology for producing hydrogen has not yet been expanded.
Today's ideal hydrogen production is made by electrolysis of waterSince hydrogen is also produced by electricity, why not just use electricity?
Electric vehicles are the product of a new generation of technological innovationCompared with the old fuel vehicles, he is better able to integrate new technologies into the car.
Although the tram has the frame of a car, it is more like a mobile phone with four wheels, and the same appearance is actually more like a product of two eras than a gasoline car.
This is also the factor that it can sweep the world even if the power technology is not yet mature.
Speaking of trains, here is a misconception about trains.
People always think that the battery of the tram needs to be replaced in a few years, but in fact, many people keep the battery capacity at about 80% until the vehicle is scrapped.
Nowadays, most of the battery packs of vehicles use ternary lithium batteries, which can be charged and discharged 1,000 times.
The so-called number of cycles is to completely charge and completely deplete the battery pack, this process can be a single charge and discharge or multiple times, not a single charge.
Based on the current Tesla modely range of 554 688km, the whole car will only have energy attenuation after running 500,000 or 600,000 kilometers.
You must know that the life of the fuel vehicle of the general CVT gearbox is 300,000 kilometersIn addition, the simple structure of the tram and the lower failure rate mean that there is less money spent on maintenance and maintenance.
Usually, except for the damage of the battery pack, most of them only need to be maintained once a year or 20,000 kilometers.
The single cost is 500 1000 yuan, and the cost of tires, brake pads, air filters, etc. is basically the same as that of fuel vehicles.
The biggest gap with gasoline vehicles is energy consumption.
Or take Tesla modely as an example, the car needs 68 80 kWh to fully charge the vehicle, to the home store 0$55 calculation, up to $44.
Even if it's a charging station155 yuan is calculated** but 124 yuan, on the other hand, the same mileage of fuel vehicles, energy ** should be at least 300 yuan.
To the average salaried person 1Calculated for 50,000 kilometers, the total cost of electricity is 1,800 yuan, and the fuel cost is about 77,000 yuanAfter three years, you can almost save a down payment of less than 100,000 yuan.
There are always people who say that the insurance of new energy vehicles is about 10,000 yuan, and all the money saved by refueling is paid for insurance, but these are rumors at all.
The owner of the BYD Han EV said that his insurance premium for the first year was 6,000 7,000 yuan, and the premium for the next year was reduced to 5,000 yuan.
Volkswagen Magotan at the same price, the premium for the first year is 5000, and the premium for the next year is 4000, and the premium for the tram is indeed higher, but it is not as exaggerated as it is said on the Internet.
So this is the reason for the gradual growth of the new energy marketAlthough everyone knows that new energy charging is troublesome, it is really fragrant to save money.
Finally, when it comes to the problem of low vehicle value retention, the five-year value retention rate of new energy is now one to two percent, and the fuel vehicle is about four to five percent (subject to the actual situation in various places).
Therefore, if it is a comparison of hundreds of thousands of new energy vehicles and fuel vehicles, the money saved from electricity bills can completely fill this hole.
However, this theory is not suitable for car owners whose time is money, and their lives are fast-paced.
Even if the charging car is getting higher and higher, it will take an hour to charge it for a single chargeCoupled with the fact that the mileage is lost and the number of charging times increases, the time on the road will be longer.
For them, the money saved by the tram may not be able to make up for the loss of time, so the money saved here is only for the majority of wage earners.
So in this case, why is Akio Toyoda still singing about electric vehicles, saying that its market share is at most 30%.Was it his desperate attempt to break the can or was there another cause?
Toyota's decline has its helplessness of slow stepsHowever, it does reflect the inherent problems of electric vehicles, which are determined by their technical routes.
First of all, the shortcomings of pure electric vehicles, battery technology has not been much innovative for about 20 years, and the existing lithium batteries are only optimized, which is destined to have little change in charging time and mileage, and it takes longer to fully charge.
In addition, electric vehicles are too affected by the weather, and the range is relatively short when it is cold.
This is where the charging pile comes in.
Nowadays, charging piles are divided into home charging piles and charging stations for charging piles.
The investment in the former is too large and the speed of charging pile replacement is too fast, so that cheap household electricity cannot be used, and the electricity price of the charging station cannot fully reflect the best advantages.
At Xiaomi's press conference, Lei Jun said that 40% of the cost of the tram is on the battery, and the expensive battery is expensive but most of them are installed under the vehicle, and it is inevitable that ordinary cars will bump into the ground.
The structure of the fuel vehicle is simple, and there is almost no major damage when it touches the ground, while the tram site sometimes needs to replace the battery of the whole vehicle because of a small abrasionReplacement** is close to the price of the car.
In addition to **, the safety of batteries is now also questioned, and it is revealed that new energy spontaneous combustion has occurred in many places, and its poor safety has greatly reduced its popularity.
Compared with pure electric vehicles, hybrid vehicles solve the problem perfectly.
Whether it is a range extender or a hybrid, the essence is the combination of a gasoline engine and an electric motor, but not only whether the gasoline engine is directly used as power.
The hybrid can use electricity to complete short-range transportation every day, and at the same time, it can also solve the problem of range anxiety and slow charging speed of the tram, but its ** is much higher than that of cars of the same level.
When it comes to the maintenance of hybrid vehicles, the cost is higher due to the complex mechanical structure that requires more special maintenance and repair.
In addition, the battery capacity of hybrid vehicles is very limited, which makes the number of cycles decay rapidly, and the replacement cycle is definitely much shorter than that of pure electric vehiclesIn this case, the tide of maintenance is rising.
It can only be said that hybrid has the advantages of two types of cars, and has the disadvantages of two cars, and is more suitable as a transitional product.
Last but not least, there are a variety of high-tech trains, which are popular among young people because of their functionality and fun.
However, as a vehicle attribute, its mileage and charging time are weaker than those of traditional cars.
In the past, the vehicle looked at three major piecesNowadays, it depends on whether the vehicle has a smart assistant and a large screen, which is unacceptable to many traditional car owners.
If battery technology cannot be innovated, it may be possible that the upper limit of electric vehicles will be locked at 30%, as Akio Toyoda said.
The emergence of new energy vehicles has reduced environmental pollution, and it is also more powerful in power and has a better driving experience, which is its advantage.
However, issues such as environmental awareness and energy security are becoming more and more prominentThe existing new energy vehicles cannot replace traditional cars, which may affect the overall upgrading of China's industry.
The development of new energy can not only save money, but also let car owners have more sense of gain.
If the vehicle can be more versatile on the premise of increasing the charging speed, then who cares if you are an electric car or a petrol car?
