The replacement of fuel vehicles by new energy vehicles is regarded as the future development trend. However, despite the many advantages of new energy vehicles, the development trend of pure electric vehicles is not as smooth as people expect. There are three main shortcomings faced by pure electric vehicles, and if these defects are not solved, they will seriously affect the process of replacing fuel vehicles.
Defect 1: Potential safety hazards.
Liquid lithium batteries used in BEVs are flammable, which makes them highly susceptible to short circuits and ** in the event of a collision. In contrast, fuel vehicles will automatically lock the oil circuit in the event of an accident and collision, and even if it spontaneously combusts, there will be a certain precursor, leaving more time for passengers to escape. Therefore, in terms of safety, pure electric vehicles need to be improved urgently.
Defect 2: Range anxiety.
Range anxiety in EVs is a perennial problem. Although the cruising range marked by the manufacturer can reach 440km, the actual test cruising range is often only about 300km, which is less than 75% of the theoretical value. In addition, the popularity of charging piles is also a major issue. During peak periods such as holidays, if you don't plan your charging time in advance, you may need to spend time waiting in line to charge. In contrast, a gasoline vehicle can set off immediately after filling up with fuel without worrying about battery life.
Defect 3: Serious depreciation.
Compared with the value retention rate of fuel vehicles, the depreciation of pure electric vehicles is more serious. Two years later, the value retention rate of traditional fuel vehicles can be maintained at least at about 75 percent, while the second-hand cars of pure electric vehicles are often only four or five percent off. This is mainly because the technology configuration of new energy vehicles is updated quickly, and the model may be outdated in two years. In addition, the replacement of new energy vehicles is also very fast, and it is likely that three generations of models will be replaced in two years. Finally, battery issues are also an important factor affecting the value retention rate of pure electric vehicles. At present, the cost of batteries is high, and with the continuous progress of new energy vehicle technology, the life and performance of batteries are also improving. If there is a breakthrough in battery technology in the future, then existing pure electric vehicles are likely to face the risk of being obsolete.
To sum up, in order for pure electric vehicles to replace fuel vehicles, the above three shortcomings must be overcome. First and foremost, improving security is key. Reduce the risk of accidents by adopting safer battery technology and enhanced crash protection. Secondly, improving the range and charging efficiency is also a top priority. Solve range anxiety by improving battery technology and charging infrastructure to shorten charging time and improve charging efficiency. Finally, the issue of improving the retention rate also needs attention. By improving the technological configuration and replacement speed of new energy vehicles, as well as reducing the cost of batteries, etc., we will improve the value retention rate.
In addition, ** and related institutions should also increase support for new energy vehicles. For example, more policy incentives and subsidies could be provided to encourage consumers to buy new energy vehicles. At the same time, strengthening the construction and maintenance of charging facilities is also one of the necessary measures. Only when charging facilities are more convenient and popular, can we better promote the development and popularization of new energy vehicles.
In conclusion, there are many technical and social challenges that need to be overcome in order for BEVs to replace combustion engine vehicles. This can only be achieved through the combined effect of continuous scientific and technological innovation and policy support and market promotion. At the same time, we also need to see that the development trend of new energy vehicles is irreversible, but it is also a gradual process, which requires the joint efforts of all parties to achieve the ultimate goal.
