1. Differences in economic performance
At present, there are many indicators about the economy of electric vehicles, but they are limited to the calculation and comparison in the field of electric vehicles. They cannot be directly compared and analyzed with the economy of traditional fuel vehicles. It is necessary to establish an indicator to make the economy of the two comparable. Here, "energy rate" is used as a unified indicator for comparison. The so-called energy rate refers to the amount of money required for the energy consumed per unit mileage of the vehicle, and its unit is yuan/100km. The following is a comparison between the electric car RAV4EV produced by Toyota Motor Corporation and the fuel car RAV4. Table 1-7 is a comparison of the full life economy under the operating cycle conditions in 2008.
Table 1-7 Comparison of the full life cycle economy of Toyota RAV4EV and RAV4
According to Table 1-7, since RAV4EV does not consume fuel during operation, its energy rate is only 19.6% of RAV4, and its economic efficiency during operation is significantly better than that of traditional fuel vehicles. However, the vehicle price and battery cost account for a considerable proportion of the RAV4EV's life cycle cost structure, accounting for 89.2% of the total cost. These two costs seriously affect the economic efficiency of electric vehicles. Of course, the current government subsidies for electric vehicles are also very high, so the costs of the two are roughly the same.
2. Differences in Business Models
The traditional car sales models mainly include: 4S store model, car trading market, car supermarket, etc. Due to the fundamental change in the form of energy consumption, the energy supply network, energy supply time and form, and the proportion of vehicle value composition are very different. These huge differences determine that electric vehicles must adopt a different business model from fuel vehicles. At present, there are mainly the following new business models for electric vehicles in my country.
The first is the vehicle-battery overall purchase model, in which energy replenishment is mainly based on charging and supplemented by quick replacement. The advantage of purchasing is complete ownership, but the disadvantage is that the price is higher, and consumers need to bear the cost of battery maintenance and subsequent replacement, and mainly rely on self-charging to replenish electricity.
The second is to separate the vehicle from the battery and mainly replace the battery. In this model, the battery charging and maintenance are the responsibility of the charging station and other links. The advantage of this model is that it can reduce the initial purchase cost of electric vehicles, avoid the pressure of subsequent battery replacement, and the power supply is fast; but the disadvantage is that the battery operator will bear the huge financial pressure caused by the necessary battery reserves, and it is difficult to define the responsibility of the battery and the vehicle in the event of an accident.
The third is the whole vehicle leasing or sharing model, in which battery charging and maintenance are handled by dedicated personnel. These new business models are all in their infancy, each with its own advantages and disadvantages, and are not mature. In the absence of a breakthrough in automotive power battery technology in the short term, it is urgent to further promote innovation in electric vehicle business models to solve the current difficulties in the industrialization and scale of electric vehicles.
Compared with traditional fuel vehicles, electric vehicles have the advantages of environmental protection and energy saving, but they also have the disadvantages of difficult to overcome technical difficulties, but this does not affect the industrial development of electric vehicles in the future. At present, countries around the world are vigorously developing electric vehicles, forming a good situation. I believe that the popularization of electric vehicles will be realized in the near future.
3. Advantages of Electric Vehicles
1. Low environmental pollution This is the most prominent advantage of electric vehicles. Electric vehicles do not produce exhaust gas during use, and there is no problem of air pollution compared to traditional fuel vehicles. Some people say that the secondary energy used by electric vehicles - electricity pollutes the atmosphere when it is generated in thermal power plants, and it just transfers the pollution from cities to suburbs. In fact, electric vehicles do not simply change the location of air pollution. Compared with traditional fuel vehicles, they do reduce pollution. Because the source of electricity is diverse, many energy sources such as hydropower, wind power, solar energy, tidal energy, and nuclear energy can be efficiently converted into electricity. Even if the electricity of electric vehicles comes entirely from thermal power plants, its overall energy utilization efficiency is higher than that of conventional fuel vehicles in cities. In other words, the use of electric vehicles still reduces most of the air pollution. In addition, if charging is done at night to avoid peak electricity consumption, energy waste can be further reduced.
2. No noise, low noise This is the most intuitive feature of electric vehicles. Nowadays, car noise has become a serious pollution in big cities, and reducing noise pollution is also a test for the future automobile industry. Car engine noise is the main source of noise during driving. Compared with fuel vehicles, electric vehicles have an absolute advantage in this regard. It is basically quiet during driving and is particularly suitable for driving on urban roads where noise pollution needs to be reduced.
3.高效率这是电动汽车能源利用方面最显著的特点。在城市中,道路上车辆行驶较多,而且经常遇到红绿灯,车辆必须不断地停车和启动。对于传统燃油汽车而言,这不仅意味着消耗大量能源,而且也意味着更多汽车尾气排出。而使用电动汽车,减速停车时,可以将车辆的动能通过磁电效应,“再生”地转化为电能并储存在蓄电池或其他储能器中。这样在停车时,就不必让电动机空转,可以大大提高能源的使用效率,减少空气污染。
4. Simple structure, easy to use and maintain, and durable. This is the biggest highlight of electric vehicles in terms of operating costs. Compared with traditional fuel vehicles, electric vehicles are easy to operate, simple in structure, and have relatively few operating transmission parts. There is no need to replace engine oil, oil pumps, mufflers, etc., and there is no need to add cooling water. The maintenance workload is small. If there is a good battery, its service life is also longer than that of a fuel vehicle.
5. Wide range of use, not affected by the environment This is another advantage of electric vehicles. In special occasions, such as places with poor ventilation, low temperatures in winter, or places with lack of oxygen at high altitudes, internal combustion engines either cannot work or their efficiency is reduced, while electric vehicles are completely unaffected. However, the working efficiency and endurance of new energy vehicle battery packs will be reduced in cold weather.
After reading this, you will almost understand the difference between the two.
