New energy buses do have certain cost advantages. First of all, the energy cost of new energy buses is low. For buses, they operate mainly during the day and can take advantage of the low electricity prices at night, thus reducing energy costs. In addition, new energy buses are more suitable for the operational needs of the public transport system. Buses need to stop frequently to pick up and drop off passengers in their daily operations, and the characteristics of electric vehicles make them more suitable for bus operations with frequent acceleration and deceleration, improving operational efficiency and making it more convenient for drivers. In addition, the maintenance cost of new energy buses is also low. Due to the high mileage of buses, maintenance costs are an important expense, while new energy vehicles have a longer maintenance mileage and relatively low cost due to the characteristics of electric vehicles. Finally, new energy buses have no exhaust emissions, which is of great significance for the improvement of urban environmental protection awareness.
However, with the expiration of new energy buses, the cost issue has become more prominent. Whether it is to replace a new energy bus or a battery, the cost is much higher than that of fuel vehicles. Due to the high cost of power batteries, the cost of replacing batteries is between 300,000 and 600,000, and the battery life of new energy buses is usually only 6-7 years. The daily charging and discharging of buses leads to a limited number of battery cycles, requiring more frequent battery replacement, with annual costs of up to 50,000 to 100,000 yuan. In addition, the ** of new energy buses is usually between 600,000 and 1 million yuan, in contrast, the ** of fuel buses can be as low as 200,000 yuan. Therefore, considering the cost factor, the energy savings of new energy buses may not be enough to cover the cost of battery replacement. In addition, the cancellation and reduction of subsidies for new energy vehicles has also led to a decline in the enthusiasm of bus companies to replace new energy buses, and the cost has increased significantly, which is also one of the reasons why enterprises choose to use fuel vehicles. In contrast, fuel vehicles have a longer service life, can sell used cars**, and the cost advantage is more obvious.
In addition to the cost problem, new energy buses also face some problems and challenges. In the early days, the energy density of the battery was low due to the backwardness of battery technology. In order to reduce the weight of the vehicle, the cruising range can only be shortened, which leads to a further increase in electricity costs when the vehicle is constantly charging, and the actual energy cost savings are less. If you choose a long mileage, it will lead to a significant increase in vehicle cost and body weight, which will make new energy vehicles more expensive, and in turn increase energy costs, in fact, it does not achieve the low-cost effect of paper calculation. In addition, the early fast charging technology of new energy buses is immature, and the charging time is long, and it can only be charged during daytime operation. The upgrade of battery technology has made the depreciation of new energy buses faster than expected, resulting in almost no residual value of second-hand new energy buses, which further increases the cost of new energy buses. Under the combined effect of these factors, the bus companies are less interested in continuing to choose new energy buses, and are more inclined to use fuel vehicles, especially in cities with financial difficulties, the cost problem is particularly prominent, and switching back to fuel vehicles has become their inevitable choice.
The low cost of new energy buses is not as ideal as the expected version, and issues such as cost, maintenance and adaptability need to be carefully considered. Although new energy buses have certain advantages in terms of energy cost and environmental protection, with the expiration of new energy buses, the high cost of battery replacement and battery life make the overall cost of new energy buses high. In addition, problems such as early technical limitations and long charging times also caused inconvenience to daily use. Therefore, for bus companies, it is necessary to comprehensively consider the cost, technology and other aspects, and comprehensively evaluate the applicability and economic benefits of new energy buses in combination with the actual local situation. At the same time, the first department should increase the support and support for new energy buses, provide more preferential policies and technological innovation support, so that new energy buses can better develop and truly achieve the goal of low cost. In the end, only with the joint efforts of enterprises, enterprises and society, new energy public transport can become the sustainable development of urban public transport.
