New energy vehicles are ultimately powered by electricity. At present, there are only two defined directions in China: battery electric vehicles and fuel cell electric vehicles. The biggest advantage of new energy vehicles is no 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 run 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 uset mainly fuel-free electrical appliances and do not need to burn gasoline, diesel, etc. , instead use clean energies, such as electricity, solar energy, hydrogen, etc. This reduces emissions of carbon dioxide and other gases, thereby achieving the goal of environmental protection.
2. Save money. The fuel cost of a fuel vehicle is about 0.6-0.8 yuan per kilometer, but the electricity consumption costs only 0.2 yuan. In addition, the engine structure is very simple, difficult to damage, 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, energy vehiclesnew have almost no pollution and no emissions, so they are not subject to traffic restrictions and travel is more convenient.
4. High efficiency. GM new energy vehicles use new technologies and structures to improve their efficiency.
The disadvantages of new energy vehicles are:
1. Charging is difficult and slow. Since new energy vehicles have not yet become popular, many cities or regions do not have a few hours to procure new vehicles.
2. Cruising range is short. For new energy vehicles that use electricity, the storage capacity of the vehicle battery is limited, so the continuous range of the vehicle will also be limited, and it is generally impossible to travel a long distance.
3. After-sales service is not yet completeure. As the "new star" of the automobile industry, new energy vehicles are always being explored and improved in all aspects. For the after-sales maintenance of new energy vehicles, there are not many qualified maintenance personnel who cannot carry out repairs in a timely manner, which brings great inconvenience to car owners.
4. The cost is very high. In order to be recharged and used repeatedly, the additional cost of lithium batteries is necessary. Currently, batteries with temperatures above 90 degrees Celsius are required. 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 80,000-90,000 yuan.
