In the second half of this year, there was ** news revealed,Not only Baoding, but also Hubei, Hebei, Nanjing and the north have implemented new energy buses to replace fuel buses。According to the report on **, the initial reason is that the subsidy for new energy vehicles has been terminated and other reasons, which have made it difficult for new energy buses in many cities to operate, and then have to pick up the idea of fuel vehicles again. So,What is the reason for the gradual replacement of new energy vehicles that were once favored by the people because of their low environmental protection costs?
First of all, a big reason is the problem of new energy battery technology. In fact, to put it bluntly, the battery technology of the new energy buses working on the market today uses the first batch of battery technology, thereforeThe technology is not mature enough, so that the battery life is not long, the new battery wears out too quickly, and the cost of replacing the battery is high。However, it is precisely because of the vigorous promotion of new energy vehicles and the promulgation of relevant subsidy policies by the transportation department in previous years that the number of electric buses has increased dramatically in recent years, and as of the end of 2022, the number of electric buses has accounted for more than half of the total number of buses. But the real problem is that with the immature new energy battery technology at that time, the rapid increase in electric buses at that time is now plagued by a large number of bus drivers due to battery damage and recession, and even some drivers do not even dare to turn on the air conditioner in summer because of serious battery wear. And that's not all,The cost of replacing the battery is hundreds of thousands of dollars for a car。If it is a batch of buses as a whole, an 8-meter-long electric bus ** is between 700,000 and 800,000, and a 10-meter to 12-meter is required to be millions or even higher, and the cost is simply not too high, and even much higher than fuel vehicles. And politicsThe subsidy for new energy vehicles sown by the government is only 80,000 yuan per vehicleNot to mention that now this kind of subsidy has been cancelled, and the bus is relying on the relevant state subsidies to survive, and the bus company basically can't make any money. In this regard, fuel buses may be more advantageous in terms of life and procurement costs.
Secondly, the safety of new energy buses is also a point of concern。Because it is a bus, as a means of public transportation, the usual passenger capacity is higher, driving safety is related to the safety of many lives, once a safety problem occurs, the situation will be very serious, so the safety of the bus has attracted much attention. Everyone's doubts about new energy buses are not groundlessIn China, the loss of personnel and property caused by the spontaneous combustion of new energy vehicle batteries occurs frequently in summer。The total number of occurrences throughout the year is about 1,000, which shows that the potential safety hazards of new energy vehicles have attracted much attention. Compared to the spontaneous combustion of oil vehicles,New energy vehicles have a fast spontaneous combustion speed, high difficulty to extinguish, and a high risk factor, and a higher likelihood. Especially in summer, in the hot weather of summer, the probability of new energy vehicle failure** is as high as 66%. This is largely due to the fact that many new energy battery companies have increased the energy density of the battery and reduced the stability of the battery cell in order to obtain a longer battery life, which further aggravates the easy loss of battery control. For new energy buses, the battery is generally placed at the bottom of the car, once the battery is accidentally bumped and damaged, the whole battery must be replaced together, the cost is higher, if not replaced in time, the probability of accidents during the driving process will be higher。This also highlights the uncontrollable nature of battery problems. Then there is the problem of battery life, at present, if it is equipped with the largest battery, it can only last about 200 to 300 kilometers, and the battery life is even lower. For the northern region that uses the most new energy buses, it is precisely the need for high endurance, because the low temperature environment in the north will reduce the electrolyte activity in the battery, resulting in a significant decrease in battery life and slow charging, which not only can not meet the requirements of frequent bus driving, but also will produce a large cost problem.
Moreover, an in-depth comparison of fuel buses, in fact, it is not difficult to find the disadvantages of new energy buses. One of the important reasons why new energy vehicles can be favored is intelligent experience. However, the biggest use of buses is only for commuting, and there is no need for intelligent experience at all, but to take into account practical needs such as stability, durability, safety, service life and cost performance. The battery attenuation of new energy vehicles should be faster and the service life should be shorter when it is started all year round, while the engine performance will not be affected when the fuel vehicle is started for a long time。Therefore, for buses alone, perhaps the solution of gasoline vehicles is clearly better.
For buses, the gradual conversion from new energy to fuel vehicles does not mean that new energy vehicles are not good, but for the choice of fuel vehicles or new energy vehicles is based on the needs of consumers with different industries and preferences for different cars.
In fact, this is also a better reminder of the shortcomings of new energy vehicles, so as to prompt new energy vehicle companies to further solve the safety, cost, battery life and other problems of new energy vehicles, so as to provide better early experience for the breakthrough and competition of new energy vehicles in the future, so that new energy vehicles can develop better and better in the future.
