What are the advantages and disadvantages of Changhe New Energy Vehicle?
New energy vehicles are ultimately driven by electricity. At present, there are only two directions defined in China: battery electric vehicle and fuel cell electric vehicle. The biggest advantage of new energy vehicles is zero carbon dioxide emission, and the biggest disadvantage is that they are too expensive.

To put it bluntly, new energy vehicles can save energy and reduce emissions, and they can go on the road without gasoline. As we all know, gasoline is a kind of non-renewable energy, and less use will pollute the environment, so the development of new energy vehicles is not accidental but inevitable.

The advantages of new energy vehicles are:

1. New energy vehicles are environmentally friendly. New energy vehicles mainly use non-fuel power plants and do not need to burn gasoline or diesel. Instead, we use clean energy, such as electricity, solar energy, hydrogen and so on. In this way, the emission of carbon dioxide and other gases is reduced, thus achieving the purpose of protecting the environment.

Save money. The fuel cost per kilometer of a fuel truck is about 0.6-0.8 yuan, but only 0.2 yuan is needed for electricity. In addition, the structure of the motor is very simple, it is not easy to be damaged, and it does not need frequent maintenance.

3. New energy vehicles do not need to be restricted. Due to the serious environmental pollution, in order to alleviate the environmental pressure, many cities have adopted the method of limiting the number of cars to limit the travel of private cars. The new energy vehicle is almost zero pollution and zero emission, so it is not within the limit and it is more convenient to travel.

4. High efficiency. Generally, new energy vehicles adopt new technologies and new structures to improve efficiency.

The disadvantages of new energy vehicles are:

1. It's difficult to charge, and slow rivers are popular. Many cities or regions lack charging piles for charging new energy vehicles, which makes charging inconvenient. In addition, the power plant system of new energy vehicles is not very mature, and charging is slow, usually taking several hours, which is inconvenient.

2. The cruising range is short. For new energy vehicles that use electricity, the continuous mileage of vehicles with batteries will also be limited, and it is generally impossible to drive long distances.

3. The after-sales service is still immature. As a "new star" in the automobile industry, new energy vehicles are still being explored and improved in all aspects. For the after-sales maintenance of new energy vehicles, there are not many skilled maintenance personnel, which can not be repaired in time, which brings great inconvenience to the owners.

4. The cost is very high. In order to be able to charge and use repeatedly, the extra cost of lithium battery is about 2000 yuan/kwh. If a car lasts 500 kilometers, it needs a battery of more than 90 degrees. The cost is 6.5438+0.8 million yuan. Even if the cost can be reduced to the cost of lead-acid batteries on a large scale in the future, it will cost 80,000 yuan to 90,000 yuan.
