No pollution, low noise
Electric vehicles do not have the exhaust gas produced by internal combustion engine cars when they work, do not produce exhaust pollution, and are very beneficial to environmental protection and air cleanliness, almost "zero pollution". As we all know, CO, HC and NOX, particulates, odor and other pollutants in the exhaust gas of internal combustion engine vehicles form acid rain acid fog and photochemical smog. Electric vehicles have no noise produced by internal combustion engines, and the noise of electric motors is less than that of internal combustion engines. Noise is also harmful to human hearing, nervous, cardiovascular, digestive, endocrine, and immune systems.
A single source of electricity
Compared with hybrid electric vehicles and fuel cell vehicles, pure electric vehicles replace the fuel engine with an electric motor, low noise, no pollution, and less space and weight occupied by the electric motor, oil and transmission system can be used to compensate for the needs of the battery. And because of the use of a single electrical energy source, the electronic control system is greatly simplified compared with hybrid electric vehicles, reducing the cost, and can also compensate for part of the price of the battery.
Simple structure and easy maintenance
Compared with internal combustion engine vehicles, electric vehicles have simple structure, fewer operating and transmission parts, and less maintenance work. When the AC induction motor is used, the motor does not need maintenance, and more importantly, the electric vehicle is easy to manipulate
High energy conversion efficiency
At the same time, it can recover the energy during braking and downhill, and improve the utilization efficiency of energy.
Studies of electric vehicles have shown that their energy efficiency has surpassed that of gasoline engines. Especially in the city operation, the car stop-and-go, driving speed is not high, electric vehicles are more suitable. Electric vehicles do not consume power when they stop, and during the braking process, the motor can be automatically converted into a generator to realize the reuse of energy during braking 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 driven by a battery car, its energy efficiency is higher than after refining into gasoline, and then driven by a gasoline engine, so it is conducive to saving energy and reducing carbon dioxide emissions.
Smooth the peak-valley difference of the power grid
It can be charged at night using the cheap "valley electricity" of the grid, which plays the role of calming the peak-valley difference of the grid.
The application of electric vehicles can effectively reduce the dependence on oil resources, which can be used for more important aspects of limited oil. The electricity charged to the battery can be converted from coal, natural gas, hydro, nuclear, solar, wind, tidal and other energy sources. In addition, if the battery is charged at night, it can also avoid the peak of electricity consumption, which is conducive to the power grid balance load and reduce costs.
