What are the advantages and disadvantages of Singularity new energy vehicles?

New energy vehicles are ultimately driven by electricity. At present, there are only two directions defined in China: battery electric vehicles and fuel cell electric vehicles. The biggest advantage of new energy vehicles is zero carbon dioxide emissions, but the biggest disadvantage is that they are too expensive.

To put it bluntly, new energy vehicles save energy and reduce emissions, and can be on the road without gasoline. As we all know, gasoline is a non-renewable energy source. If it is used less, it will pollute the environment. Therefore, 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 devices and do not need to burn gasoline, diesel, etc. , instead use clean energy, such as electricity, solar energy, hydrogen, etc. This reduces the emission of carbon dioxide and other gases, thus achieving the purpose of protecting the environment.

2. Save money. The fuel cost of a fuel vehicle is about 0.6-0.8 yuan per kilometer, but the electricity consumption only costs 0.2 yuan. In addition, the structure of the motor is very simple, not easily damaged, and does not require frequent maintenance.

3. New energy vehicles do not need to travel in limited quantities. Due to serious environmental pollution, in order to alleviate environmental pressure, many cities have adopted methods to limit the number of cars to limit private car travel. However, new energy vehicles have almost zero pollution and zero emissions, so they are not within the scope of traffic restrictions and travel is more convenient.

4. High efficiency. GM new energy vehicles use new technologies and new structures to improve efficiency.

The disadvantages of new energy vehicles are:

1. Charging is difficult and slow. Since new energy vehicles are not yet popular, many cities or regions lack charging piles for charging new energy vehicles, making charging inconvenient. In addition, the power plant system of new energy vehicles is not very mature yet, 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 storage capacity of the vehicle battery is limited, so the continuous driving range of the vehicle will also be limited, and it is generally impossible to drive a long distance.

3. After-sales service is not yet mature. As the "new star" of the automobile industry, new energy vehicles have not many skilled maintenance personnel in all aspects, which has brought great inconvenience to car owners.

4. The cost is very high. In order to be able to be recharged and used repeatedly, the additional cost of lithium batteries is necessary. The current cost of power lithium batteries is around 2,000 yuan/kWh. If a car has a driving range of 500 kilometers, it needs a battery with a temperature of more than 90 degrees Celsius. The cost is 180,000 yuan. Even if the cost can be reduced on a large scale in the future to reach the cost of lead-acid batteries, it will still cost 80,000 to 90,000 yuan.
