Electric vehicle concept

Automobile adopting high-efficiency rechargeable battery or fuel cell as power sources Electric vehicles refer to vehicles powered by electric energy, which generally use high-efficiency rechargeable batteries or fuel cells as power sources. Electric vehicles no longer need internal combustion engines, so the electric motor of electric vehicles is equivalent to the engine of traditional vehicles, and the battery is equivalent to the original fuel tank. As electricenergy is a secondary energy source.

Electric vehicle concept

It can come from wind energy, water energy, nuclear energy, thermal energy, solar energy and other ways, so it is a very promising alternative energy vehicle. Electric vehicles belong to zero-emission vehicles. Electric vehicle consists of six parts: chassis, body, battery pack, motor, controller and auxiliary facilities battery. Ince the motor has good tractioncharacteristics,
Therefore, the transmission system of the battery car does not need a clutch and a transmission. Vehicle speed control can be achieved by the controller through the speed control system to change the speed of the motor. The advantages of electric vehicles are that they do not emit harmful gases that pollute the atmosphere, that even in terms of power consumption, other pollutants besides sulfur and particulates are significantly reduced, and that power plants are mostlybuilt far from densely populated cities.
It is less harmful to human beings, and the power plant is fixed and centralized, so it is easy to remove all kinds of harmful emissions, and there are related technologies. Because electricity can be obtained from a variety of primary energy sources, such as coal, nuclear energy, hydropower and so on, people's worries about the depletion of oil resources are relieved. Electric vehicles can also make full use of the surplus power at night when the power consumption is low, so that the power generation equipment can be fully utilized day andnight.
And that economic benefit is greatly improve. Relevant research shows that the same crude oil is refined, sent to a power plant to generate electricity, charged into a battery, and then driven by the battery. Its energy utilization efficiency is higher than that of gasoline, which is refined and then driven by a gasoline engine. Therefore, it is conducive to saving energy and reducing carbon dioxide emissions. It is these advantages that make the research and application of electric vehicles a"hot spot" in the automotive industry.
How clean electric vehicles are is a matter of concern. Although electric vehicles are inherently clean, air pollution and solid waste may be generated in the process of generating electricity to charge the batteries of electric vehicles. If the power plant uses clean energy, such as solar power or hydropower, its pollutant emissions arenegligible.
But if a power plant uses traditional fuels such as coal for combustion to generate electricity, it will produce pollution, such as particulate matter, sulfur oxides, nitrogen oxides, hydrocarbons and carbon monoxide, while emitting carbon dioxide as a greenhouse gas. In a sense, however, it is easier to control pollution at the power station than at eachindividual vehicle.
Power plants are often located outside urban centers with high air pollution; more importantly, we will increasingly use renewable energy to generate electricity, such as biomass, wind, geothermal orsolar energy, which will be clean energy.
