Problems solved by technology

[0002] At present, there are two major bottlenecks in the development of electric vehicles. One is the battery on the vehicle. From the perspective of recent technology, there are many problems such as volume, weight, price, material, safety, charging speed, and lifespan. In addition, the production of batteries The process is a process of high pollution, resource consumption, and damage to the ecological environment. These characteristics bring difficulties to the industrialization of electric vehicles; the other is the problem of charging infrastructure on the ground. On the one hand, due to the long charging time, a large amount of charging or Power exchange facilities bring great difficulties to municipal construction. These facilities occupy a large amount of ground area, are not conducive to unified management, and have high operation and maintenance costs. On the other hand, electric vehicles need frequent parking and charging, which brings great inconvenience It is a great inconvenience, and the short mileage makes it impossible to travel long distances
