With the continuous increase of energy consumption, the world-wide energy shortage is an unchangeable fact. For the automobile industry, the fuel shortage will be further aggravated with the sharp increase in automobile production. The mandatory fuel consumption of various countries The promulgation of regulations and exhaust emission regulations will also prompt the governments of various countries to compel and guide automobile manufacturers to find a way out in order to develop energy-saving automobile products as soon as possible. It is necessary to use alternative energy sources or adopt more reasonable energy utilization methods. From the perspective of energy and environmental protection, although electric vehicles are recognized as "future vehicles" by the world's automobile manufacturing industry, due to the limitation of vehicle battery performance, the driving range of electric vehicles is very limited, and they cannot be charged anytime and anywhere. The industrialization process of electric vehicles is slow. Despite this, there are still a large number of different forms of electric vehicles. For example, electric bicycles are more suitable for use when the speed does not exceed 25km/h, and the activity radius is within the range of 15-20 kilometers; Driving within 20km/h, it is more stable than bicycles, suitable for use within a radius of 30km; electric rickshaws and electric motorcycles are more suitable for driving within the speed range of 20-70km/h, and electric rickshaws are suitable for transporting children to and from school. City sightseeing for tourists; electric golf carts, whose speed is usually lower than 25km/h, are only suitable for use in local areas such as golf courses, and cannot be driven on the road; there are also sightseeing cars, police patrol cars, road cleaning electric cars and multi-purpose Electric vehicles and so on continue to enter people's lives.

Besides, along with the rapid growth of car ownership, road vehicles are congested, blocked, traffic accidents occur frequently, and parking difficulties occur everywhere. According to the statistics of many parties, the proportion of single-person driving travel accounts for as much as 70%. There are many, and the volume of the vehicle is large, the flexibility is reduced, and the handling is not good when driving at high speed. The traffic accidents caused by high-speed vehicles on the road have also caused greater harm. In order to solve these problems, it is necessary to develop a small electric vehicle for one person.

China Patent Office disclosed a CN101041373A patent application on September 26, 2007, and the name is a van-type single-person electric vehicle, which includes a frame, a compartment, and a DC brushless motor.
