What are the advantages and problems of electric vehicle development?

Advantages: 1. Electric vehicles.

The advantage is first of all to save energy, because the main energy source of electric vehicles is electricity, that is to say, gasoline will not be used at all, so in this case the pollution emissions of electric vehicles are almost zero, for the protection of the environment.

It is a good choice and belongs to the environmentally friendly travel tool.

2. China**.

At present, there is some support for electric vehicle policies, although the intensity has been reduced, but at least in first-tier cities.

then you will get some benefits. First of all, it will be easier for you to play the card, and secondly, there are certain preferential policies in terms of taxes and fees! This is more attractive to ordinary people who can't get a license plate.

Third, electric vehicles are more convenient to drive, and at present, electric vehicles are a gear, which means that there is almost no need to operate. The speed at which you can move depends on how hard you can accelerate, so it's easier to drive and easier to pick up.

Disadvantages: First, the disadvantages of electric vehicles are also more, first of all, the electric vehicle market uses fewer people, so the cost of electric vehicle maintenance is high, once there is any problem, then you must go to the 4S store for maintenance, so that a time down at least about 1,000 yuan.

Second, the market share of electric vehicles.

Very low, so the value of the value of the appreciation rate is even lower, the general new electric car, as long as a consumer, directly depreciated by more than 60 percent, so that the consumer who bought the car suffered heavy losses, can only use it himself, sell it can be said to be extremely cost-effective!

Third, we know that electric vehicles have only one gear, so there is hardly any driving feeling when driving, and at the same time the steering wheel of electric vehicles.

The pointing is blurred, so there is only one directionality when driving, and there is no precise directivity of the car, so the electric car is known as an old-age scooter.

Fourth, if you drive an electric bicycle in winter, the battery consumption is very large, generally speaking, an officially announced car with a mileage of 300 kilometers, at least one-third of the mileage will be consumed in winter, so it can run more than 200 kilometers, so buying an electric car can be said to be a big problem in driving.

Fifth, the battery consumption of electric vehicles is also worth considering, generally speaking, a group of batteries ** is at least about 3,000 yuan, so that the conversion of your electric car replacement battery is at least 60,000 yuan! This ** can almost buy a gasoline car, so you must consider the cost of this aspect when buying.

6. The process of charging electric vehicles is very troublesome, generally taking at least two hours, but this is fast charging. There is a lot of depletion to the car's battery. However, if you adapt to slow charging, it is generally more than eight hours. In this case, there is no way to deal with anything urgent.

The advantages of electric vehicles are, first and foremost, energy savingsBecause the main energy source of electric vehicles is electricity, that is to say, gasoline will not be used at all, in this case, the pollution emissions of electric vehicles are almost zero, which is a good choice for protecting the environment and belongs to environmentally friendly travel tools.

At present, China has some support for electric vehicle policies, although the intensity has been reduced, but at least in the first-tier cities, there will be some benefits.

There are many disadvantages of electric vehicles, first of all, there are fewer people in the electric vehicle market, so the cost of electric vehicle maintenance is high, once there is any problem, then you must go to the 4S store for maintenance, so that at least about 1,000 yuan at a time.

The main classifications.

1. New energy vehicles: new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

2. Pure electric vehicles: According to different uses, pure electric vehicles can be divided into three types: electric cars, electric trucks and electric buses.

Advantages: 1: Less pollution, more environmentally friendly 2: There is a subsidy policy, which can save money 3: Less noise, more comfortable 4: More energy saving.

Disadvantages: 1: short mileage 2: difficult to charge 3: slow charging 4: after-sales service needs to be strengthened.

Electric vehicles are the future development trend, whether from the environment, or the national energy level, fuel vehicles will eventually be replaced by electric vehicles, but this is a process, to solve the current shortage of electric vehicles, in order to achieve this goal.

The current shortcomings of electric vehicles:

1. The cost of batteries is high, and pure electric vehicles are still much higher than fuel vehicles after state subsidies. Taking Roewe IE6 as an example, after a subsidy of about 10,000 yuan, the price of a naked car is still at 170,000 yuan (entry-level), while the Roewe E6, the entry-level fuel car is less than 100,000. ** is an important factor in the impact;

2. Secondly, the charging equipment is imperfect and lacks sufficient and effective charging facilities;

3. The cruising range is insufficient. The official range can only be discounted by 7%;

4. High maintenance costs in the later stage. I bought pure electricity to save fuel, but the later maintenance cost can make up for the oil you saved;

In general, pure electric vehicles are a must in the future, but they need technical and policy support.

The biggest problem with electric vehicles is that the problem of car charging and range is more troublesome.

In the cruising range, charging is inconvenient.

At present, the main disadvantage of electric vehicles is that the mileage is relatively short, the charging time is relatively long, and the winter start-up has certain obstacles in the cold areas of the north, but electric vehicles are mainly more energy-saving and environmentally friendly, which is the general trend of future development.

The main advantage of electric vehicles is that they are environmentally friendly. No contamination. And the biggest disadvantage is that you can't run too far, and you generally have to charge it after seventy or eighty kilometers.

Electric vehicles, that is, new energy vehicles, have two disadvantages, one is insufficient mileage, and the other is poor charging, which will be very troublesome if you run long distances.

1. Short mileage: The cruising range of domestic pure electric vehicles is mostly about 150 kilometers, coupled with factors such as weather, road conditions, and batteries, the actual cruising capacity is more than 100 kilometers. You need to plan your route well before you go out by car, which is really troublesome.

2. Long charging time: Generally, the normal charging time is about 8 hours, and fast charging also takes 1-2 hours.

Advantages of electric vehicles.

1. Environmental protection: electric vehicles use power battery packs and motor drive power, which will not produce exhaust gas when it works, and does not exhaust pollution, which is very beneficial to environmental protection and air cleanliness, and can be said to be almost "zero pollution".

2. Low noise: Electric vehicles do not make noise like transmission cars, and the noise it produces is almost negligible.

3. Economy: The cost of electric vehicles is low, only about one-fifth of that of gasoline vehicles. Moreover, the energy conversion efficiency is high, and at the same time, it can improve the energy utilization efficiency of braking and downhill.

At night, the cheap "valley power" of the power grid is used for charging, which plays a role in smoothing the peak-to-valley difference of the power grid.

Disadvantages of electric vehicles are 1: difficult to charge.

Now our country's electric vehicle charging facilities are not perfect, so the biggest difficulty in driving electric vehicles is charging, itself we park is a headache, not to mention find a parking space after charging, and the public charging pile is very lacking, which also seriously affects the experience of driving electric vehicles.

The second disadvantage of electric vehicles: short mileage.

Due to the limitation of the battery, the range of most pure electric vehicles is not very ideal, most of them are about 200 kilometers, although 9 percent of people travel only 50 kilometers a day, but Chinese consumers have higher requirements for mileage than foreign countries, because we generally have only one car at home, and some countries have several cars. If you want to go on a family trip on the weekend, then an electric car is really not a good choice.

The third disadvantage of electric vehicles: slow charging.

Nowadays, many owners who buy electric vehicles use slow charging piles, and it takes at least 6-8 hours for a car to be fully charged. Although we can use the night rest time to charge, but once we encounter any unexpected situation, then the shortcomings of pure electric vehicles will be seriously exposed.

Disadvantages of electric vehicles are four: unsound after-sales service.

Although the architecture of pure electric vehicles is much simpler than that of fuel vehicles, but because the power part is completely different from fuel vehicles, there are still a lot of troubles in maintenance and maintenance, one is the lack of car repair technicians, most of them are fuel vehicle technicians, lack of knowledge and experience in electric vehicle maintenance. If you take the initiative to repair the electric vehicle, it is very likely to cause damage to the vehicle. Another is the lack of auto parts, because the number of electric vehicles is small, and it is also very inconvenient to buy some commonly used wearing parts, and it is also very high.

First of all, the cost is higher than that of gasoline vehicles of the same level, because the supporting industrial chain is not as complete as gasoline vehicles, and the scale is smaller, resulting in high cost of parts, but this can be alleviated by subsidies and other means. Although electric vehicles at this stage have such policy support, they still can't be lowered.

The second is the issue of range, which is also the most critical issue. Electric vehicles are subject to the battery structure, and the cruising range is more sensitive to temperature than gasoline engines, and the cruising range under individual conditions is only about half. In addition, compared to gasoline engines, the battery charging is too slow (some models support fast charging, which can be charged to 80% in about an hour, but a dedicated charging pile is required), which is not obvious in the case of daily short-distance commuting, but if it is a long-distance trip, driving an electric car is not going to get along with yourself.

Taking an electric vehicle with a theoretical mileage of 300 kilometers as an example, in order to ensure that there is enough emergency mileage, the longest one-way run is 250 kilometers, that is, 2 hours on the highway, and it must take several hours to charge after arriving at the destination, and it cannot be returned immediately, nor can it be driven beyond the emergency mileage.

Therefore, I personally believe that at this stage, battery-powered pure electric vehicles are only experimental products, which will not become mainstream and will not be popularized, and are only suitable for short-distance driving tools such as electric bicycles. Parallel and hybrid strong gasoline-electric hybrids will soon become widespread and become mainstream until pure electric power solves the problem of how to charge quickly like a gasoline engine, such as by adding energy blocks as in the Transformers anime.

What do electric cars look like? It is indeed the trend of the future, and there are indeed many shortcomings, today I will only talk about the shortcomings, and if you want to buy an electric car, you should consider these problems first.

1. High manufacturing cost.

2. Short cruising range.

3. Long charging time.

4. The after-sales foundation is not perfect.

In fact, there are still many disadvantages of using a car, such as charging is not very convenient now, and it is not very safe to run at high speed, and it is easy to run out of power halfway.

The disadvantages of making a car, its ability to last without oil, the car lasts for a long time, and the feeling of driving is not strict.

At present, there are still not many domestic charging piles, and the long-distance battery life may not be enough.

The disadvantage of electric vehicles is that they have small power and short mileage.

The disadvantage of electric vehicles is that they can't run long distances.

New energy vehicles refer to the use of unconventional vehicle fuel as the power (or the use of conventional vehicle fuel, the use of new on-board power units), the integration of vehicle power control and drive advanced technology, the formation of advanced technical principles, with new technologies, new structure of the car. The main difference is from the internal combustion engine vehicles fueled by gasoline and diesel fuel.

New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen-powered vehicles, and other new energy vehicles.

The following is an introduction to several mainstream types of new energy vehicles in the market:

1. New energy includes hybrid vehicles: hybrid vehicles that use fuel and electricity as driving raw materials. At present, major brands basically have such models, such as: Mercedes-Benz S400, BMW 5 Series, etc., these hybrid vehicles will be marked with the word hybrid.

2. Pure electric vehicle: This car is completely detached from fuel and completely relies on electricity as the driving raw material for hybrid.

3. Fuel cell vehicle: This car is also a battery car, which is a hydrogen-oxygen hybrid fuel cell, you can quickly fill the battery fuel without waiting for charging.

4. Hydrogen-powered vehicles: This car is also completely detached from fuel and uses hydrogen energy to replace fuel.

There are other new energy vehicles, such as: dual-fuel vehicles, natural gas vehicles, etc.

Now pure electric vehicles can not reach the real sense of high endurance comparable to fuel vehicles, some electric vehicles NEDC measured mileage up to 400+, but the actual run is only more than 200 to 300km, compared to fuel vehicles pure electric vehicles can not do high endurance, that is, the shortcomings of low endurance are very obvious. Even if individual models can reach 600+, they are still a minority, and the choice is not rich enough and the quality is uneven.

On the other hand, public charging piles for electric vehicles are not yet common. This means that most EV owners will encounter the problem of not being able to find a charging station when the vehicle is running out of power. Although most of them can be charged at home, public charging piles are far more efficient than home chargers.

In addition, electric vehicles are mainly powered by electric motors, which are weak at high speeds although they have low torsional strength. Why, because the characteristics of the motor is that its torque is proportional to the product and power of the speed, and the power is constant, so the low torque is strong at the start, and it will not be very meaty, but the output power that the battery-based electrical system can provide is so much, when running at high speed, the power reaches the highest and remains the same, then the speed of the motor is increased, and the torque will be reduced, resulting in the embarrassment of high-speed weakness.
