Advantages Of Pure Electric Vehicles
Aug 07, 2023
No pollution, low noise
Electric vehicles have no exhaust gas produced by internal combustion engine vehicles, and do not produce exhaust pollution. They are very beneficial to environmental protection and air cleanliness, and are almost "zero pollution". As we all know, pollutants such as CO, HC, NOX, particles, and odor in the exhaust gas of internal combustion engine vehicles form acid rain, acid mist and photochemical smog. Electric vehicles have no noise generated by internal combustion engines, and the noise of electric motors is also smaller than that of internal combustion engines. Noise is also harmful to human hearing, nerves, cardiovascular, digestion, endocrine, and immune systems.
Single power source
Compared with hybrid electric vehicles and fuel cell vehicles, pure electric vehicles use electric motors instead of fuel engines, which have low noise and no pollution, and the less space and weight occupied by electric motors, oil and transmission systems can be used to compensate for the needs of batteries; Compared with hybrid electric vehicles, the energy and electronic control systems are greatly simplified, which reduces the cost and can also compensate part of the price of the battery.
Simple structure and easy maintenance
Compared with internal combustion engine vehicles, electric vehicles have a simpler structure, fewer running and transmission parts, and less maintenance work. When an AC induction motor is used, the motor requires no maintenance, and more importantly, the electric vehicle is easy to operate
High energy conversion efficiency
At the same time, the energy during braking and downhill can be recovered to improve energy utilization efficiency;
Studies of electric vehicles have shown that their energy efficiency has surpassed that of gasoline-engined vehicles. Especially in urban operation, where cars stop and go, and the driving speed is not high, electric vehicles are more suitable. When the electric vehicle stops, it does not consume electricity. During the braking process, the electric motor can be automatically converted into a generator to realize the reuse of energy during braking and deceleration. Some studies have shown that the same crude oil is refined, sent to a power plant to generate electricity, charged into a battery, and then the battery drives a car. and reduce carbon dioxide emissions.
Smooth the peak-to-valley difference of the power grid
It can use the cheap "valley power" of the grid for charging at night, which can stabilize the peak-valley difference of the grid.
The application of electric vehicles can effectively reduce the dependence on oil resources, and the limited oil can be used for more important aspects. The electricity charged to the storage battery can be converted from energy sources such as coal, natural gas, hydropower, nuclear energy, solar energy, wind power, and tides. In addition, if the battery is charged at night, it can also avoid peak power consumption, which is conducive to balancing the load on the grid and reducing costs.
