pure electric new energy vehicle
Electric vehicles, as the name suggests, are mainly powered by electric vehicles. Most vehicles are directly driven by electric motors. Some vehicles install the electric motor in the engine compartment, and some directly use the wheels as the rotors of the four electric motors. The difficulty lies in the power storage technology. It does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted into the emission of power plants, other pollutants except sulfur and particulates are also significantly reduced. Since most of the power plants are built far from densely populated cities, the harm to human beings is relatively low. In addition, the power plant is stationary, and it is easy to remove all kinds of harmful emissions because of centralized emissions, and related technologies are also available. Since electricity can be obtained from a variety of primary energy sources, such as coal, nuclear energy, water power, wind power, light, heat, etc., people's worries about the depletion of oil resources are relieved. Electric vehicles can also make full use of the surplus electricity when the electricity consumption is low at night, so that the power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Relevant studies have shown that the same crude oil is crudely refined, sent to power plants to generate electricity, charged into batteries, and then driven by batteries, the energy utilization efficiency is higher than that after refining into gasoline, and then driving vehicles through gasoline engines, so it is conducive to saving energy. It is these advantages that make the research and application of electric vehicles a "hot spot" in the automotive industry. Some experts believe that for electric vehicles, the biggest obstacle is that infrastructure construction and price affect the process of industrialization. Compared with hybrid electric vehicles, electric vehicles require more infrastructure support, which cannot be solved by a single company. It is necessary for all enterprises to unite and build together with local government departments, so that there will be opportunities for large-scale promotion.
Advantages: The technology is relatively simple and mature, and it can be charged wherever there is power supply.
Disadvantages: The energy stored per unit weight of the battery is too small, and because the battery of the electric vehicle is more expensive and has not formed an economic scale, the purchase price is more expensive. As for the use cost, some trial results are more expensive than the car, and some results are only 1 of the car. /3, which mainly depends on the life of the battery and the local oil and electricity prices.
