Can charging stations solve the battery life problem of electric vehicles?

With environmental pollution still difficult to solve and oil and natural gas prices fluctuating drastically, energy electrification is an irreplaceable trend. In this context, the concept of electric vehicles has been hotly discussed around the world for many years. The Tesla ModelS electric car launched last year is very popular for its handsome shape, cool appearance, reasonable price, and performance comparable to gasoline power. Related domestic industries are also accelerating the layout. For electric vehicles, the problem of charging efficiency is not difficult to solve, but how to charge is a difficult problem. It is unrealistic to charge a car a few hundred meters away from the power supply of the owner's home. The solution for the government and manufacturers is to build charging stations covering both urban and rural areas. Tesla is working with Chinaminshengbank, Intime and Chinaunicom to build charging stations around its stores. But can charging stations really solve the battery problem of electric vehicles? How to build enough charging facilities on 9.6 million square kilometers of land, especially in the sparsely populated central and western regions; only in more than 650 cities, build enough free Charging equipment also has to complete a huge grid transformation project, which takes up a lot of land, which is obviously a serious waste in urban areas where land resources are scarce. After the widespread use of electric vehicles, in first-tier cities with dense users, even a 5-minute charging time will cause congestion on nearby roads, and it is obviously impossible to build more intensive facilities. This series of problems, the difficulty of charging after the popularization of electric vehicles may severely limit the development of the industry. It's better to be late than not, and a different approach may be needed to solve the charging problem: replacing the battery with an electric car seems to be a better option than stacking charging. According to the population and density of users to establish a battery rental store, the store charges the battery module in advance for users to use, which can prevent a lot of trouble. With the introduction of Tesla, the whole process of replacing the battery for the Model S electric car only takes 90 seconds, which greatly reduces The user's time has improved efficiency and reduced possible traffic congestion; secondly, the number of outlets for renting batteries is much less than that of charging stations, and the cost of land and power grid transformation is also reduced accordingly. In sparsely populated areas, users can also bring their own spare batteries to double the endurance of the car, thereby preventing the short legs of electric vehicles. In fact, in Tesla's future plans, the charging service station will include battery replacement services. However, the replacement of car batteries still has a long way to go. On the one hand, various car manufacturers are developing their own battery modules, and it is difficult to unify their standards; with current technology, replacing batteries is not like replacing households. Electrical appliances are so simple. To solve these problems, I am afraid that the overall planning of the management department and the progress of technology research and development. In any case, the electric vehicle industry is on the eve of rapid expansion. Effectively solving supporting problems, accurately choosing the development path, removing stumbling blocks on the road in advance, preventing stumbling blocks on the road, and making the entire industry subject to individual problems may be the first task of the management department. In recent years, the development of the transportation industry has not been matched, resulting in more cars and fewer cars. Stupid mistakes should serve as a warning.
