In terms of travel, people use electric motorcycles and electric vehicles very frequently. However, electric vehicles have two major problems. One is that charging is more difficult. For electric motorcycles, charging is very troublesome in highly populated places such as schools. For electric vehicles, public charging stations are far away from home and private charging piles are more expensive. The second problem is that electric vehicles will have insufficient battery life. If you need to run long distances, changing electricity is a big problem, and the charging time is relatively long. If you need to use the car during the charging process, it will be more troublesome. At the same time, the problems of high battery cost and easy loss of electric vehicles can be solved by sharing batteries. When the vehicle is dead, the fully charged battery can be replaced, which saves the long-term charging process and avoids battery loss. If the shared battery forms an industry standard, there is no need to buy batteries when buying electric vehicles, and the price will drop so that more people can afford it.
