In recent years, with the emphasis on the environment, electric vehicles have been highly praised by the state, so new energy vehicles have become a focus of attention. I believe that one day in the future, driving an electric car will become the norm. Well, there are disadvantages in all things. Below I will analyze the advantages and disadvantages of new energy vehicles, and I hope to help everyone buy a car. Pure electric vehicles can achieve zero pollution during operation and do not emit harmful gases that pollute the atmosphere. Even if the electricity consumption is converted into power plant emissions, the pollution is less than that of conventional vehicles because the energy conversion rate of power plants is higher, and centralized emissions can more easily pretend to reduce pollution control equipment. In 2014, the state and local governments gave electric vehicles a subsidy of up to 114,000 yuan. This measure can reduce the price of electric vehicles with high battery costs to the level comparable to that of traditional cars. In today's high oil prices, the operating costs of electric vehicles are much smaller than those of traditional cars. The noise and vibration levels of the motor during operation are much smaller than those of conventional internal combustion engines. In the case of idle speed and low speed, the comfort of electric vehicles is much higher than that of traditional cars. As the speed increases, tire noise and wind noise become the main source of noise, and the two return to the same level. This feature of electric vehicles will undoubtedly help to improve the NVH performance of the car. The electric power consumption of electric vehicles is 15-20kwh. After counting the losses of power plants and electric motors, the energy consumption per 100 kilometers is about 7 kilograms of standard coal. The traditional automobile consumes 10 liters of fuel per 100 kilometers and consumes about 10 kilograms of standard coal. And in the city's congested environment, the energy-saving advantages of electric vehicles will be further amplified. In the case of the lag in the construction of domestic charging facilities, charging is a major problem faced by electric vehicles. The lack of charging piles in public places has seriously affected the travel of electric vehicles. Limited by the capacity of the battery, most of the current pure electric vehicles have a cruising range of 100-200 kilometers. Although experts have repeatedly said that 90% of people travel less than 50 kilometers a day, Chinese consumers have higher requirements for endurance than Americans, because few Chinese families have more than one car, and Americans can do it. A pure electric car commutes and travels in a traditional car. Pure electric vehicles can satisfy the ordinary people to go to work, but how to solve the need for weekend outings and holiday trips? At present, most charging piles are slow-filled piles, and it takes 5-8 hours for a car to fill. Although you can use the nighttime rest time to charge, but if you encounter any unexpected situation, the shortcomings of the pure electric car's slow charging will be undoubted. Disadvantages of new energy vehicles: After-sales service needs to be strengthened Although the structure of the electric car is simple, since the power part is far from the traditional car, there are still some troubles in repairing it. The first problem is the lack of maintenance technicians. Now most of the technicians can repair traditional cars, but lack of knowledge about electrical appliances. The rush to repair electric vehicles can not only cause damage to the vehicles, but also have certain risks. The second problem is the scarcity of parts and components. The production and quantity of electric vehicles are small, so the number of parts is small and the price is high. The above are the four advantages and disadvantages of the new energy electric vehicle that are analyzed by the electric state. I don't know if it will help you, but the times are updating. I believe that the development of new energy electric vehicles will definitely get better and better. As we all know, the biggest difference between new energy vehicles and traditional fuel vehicles is that the former uses electric energy, light energy and other energy sources to drive through the electric motor, while the latter uses the internal combustion engine to consume petroleum derivatives such as gasoline and diesel. Fuels such as gasoline and diesel are derived from non-renewable oil. Although their prices will fluctuate depending on supply, policy changes and the impact of the global situation, as prices of non-renewable resources decrease, their prices will generally increase. Compared with petroleum, electric energy as renewable energy can be produced through various ways such as firepower, nuclear energy, water power, wind power and solar energy, and the price will remain stable overall. For ordinary consumers, the two different ways of charging and refueling are also significantly different in price. Take Beijing No. 92 (No. 93) gasoline as an example. The recent price is slightly higher than 6 yuan / liter. It is calculated by the comprehensive fuel consumption of 10 liters per 100 kilometers in the urban area of ​​ordinary vehicles. The cost of driving 100 kilometers exceeds 60 yuan. For electric vehicles, the new e-Golf imported from Volkswagen, which will be launched in the year, is as low as 13.6 kWh per 100 kilometers. It is divided into peak hours, normal hours and valleys during the day. The charging cost of the public charging pile is 1.4950 yuan / kWh, and the driving cost of driving 100 kilometers is about 20 yuan. In comparison, the same 100 kilometers, the cost of electric vehicles is about 1/3 of ordinary fuel vehicles. If the electric vehicle is charged by using a charging facility such as a residential family home or a residential quarter, the cost will be further reduced. Taking the 10,000-kilometre driving year as an example, the charging cost of the new energy vehicle is compared with the fuel cost of the conventional fuel vehicle. You can save at least thousands of dollars. Under the advocacy of green travel, the state and local governments have vigorously promoted the development of new energy vehicles, especially electric vehicles, in recent years, and accordingly introduced a series of policies to promote electric vehicles. In the future, 88 new energy vehicle promotion and application cities (groups) covering major first- and second-tier cities will continue to introduce a series of promotion and application policies to promote the use and development of new energy vehicles. Due to structural differences, the difference in maintenance between new energy vehicles and traditional fuel vehicles is also very obvious, and the maintenance cycle and maintenance items are very different. Conventional maintenance projects for traditional fuel vehicles mainly include the replacement of oil and filter elements, spark plugs, air filters and fuel filters. Since electric vehicles use power batteries and motors to work, there is no engine and transmission powertrain and a series of ignition devices, which reduces the need for conventional maintenance projects. Usually, the maintenance of electric vehicles is mainly to detect the wearing parts, such as tires, brake pads, etc., if there is no wear, there is no need to replace. Based on the small demand for maintenance of electric vehicles, the maintenance cycle of existing electric vehicle products in China is generally carried out in units of driving distance of 1-2 million kilometers, and the maintenance frequency is significantly lower than the conventional fuel with a maintenance cycle of 5000-10000 km. car.
