Electric vehicles are energy-saving and pollution-free, and they are convenient to travel. They are gradually accepted. When buying a car, as a consideration and choice, with the increase in the number of electric vehicles, some problems of electric vehicles are also exposed. What are the urgent needs for electric vehicles? Can it be more practical? For electric vehicles, the biggest bottleneck in electric vehicles is nothing more than its battery technology, which is beyond doubt. Among them, the endurance and power performance of electric vehicles also need to be improved.
At the same time, the safety of the battery safety of the vehicle is related to the electric vehicle. In terms of the cruising range of the vehicle, although it is constantly improving, it still faces mileage anxiety when using the electric vehicle. The automobile industry needs to be in battery technology. There is a breakthrough. Secondly, in terms of vehicle safety issues, safety issues are also a major concern for electric vehicles. Safety is not just a battery problem, it is a comprehensive issue. For example, nowadays our electrical appliances are aging, high-voltage electrical insulation is destroyed, water is infused, and so on. In addition to the existing battery technology has not yet completely broken, it will face the problem of the decline of the winter cruising range, and in the summer or overcharge, the battery will also face the situation of thermal runaway.
Although the thermal runaway of the battery has many problems, it is basically related to the safety of the vehicle. Although the thermal runaway may be caused by many factors such as machine, electricity and heat, the battery itself is aging. Man-made or mechanical damage causes thermal runaway combustion. For the car, these are basically related to the car experience and the safety of the car. Once you don't pay attention or the technical department does the upgrade, the problems are very serious.
Based on the above analysis, the current urgent need for improvement in pure electric vehicles is the performance level of power batteries and the management of power battery systems for pure electric vehicles.
