Charging pile or battery exchange, which is more reliable?

At a time when environmental pollution continues to be difficult to understand and oil and gas prices fluctuate drastically, energy electrification is a trend of no choice. In this context, the concept of electric vehicles has been hot in the world for many years. The Tesla ModelS electric vehicles that were launched last year are more popular because of their cool and cool appearance, relatively reliable price, and performance that is not inferior to gasoline power. . Domestic related industries are also stepping up their layout. Recently, a new type of lithium battery developed by Nanyang Technological University in Singapore has brought new help to the upcoming electric vehicle industry: According to Xinhuanet, this battery can be charged 70% in 2 minutes, using this technology to make the car battery can reduce the charging time of the electric car to 5 minutes.

For electric vehicles, the problem of charging efficiency is not difficult to solve, but how to charge is a problem. It is not realistic to use the owner's household power to charge cars hundreds of meters away. Setting up charging facilities at the parking lot also requires large-scale infrastructure modifications. The solution for the government and manufacturers is to build charging stations covering both urban and rural areas. Tesla is working with domestic Minsheng Bank, Yintai and China Unicom to build charging piles around its outlets.

But can recharging stations really solve the problem of electric cars? And do not ask 9.6 million square kilometers of land area, especially how to build sufficient charging facilities in the sparsely populated central and western regions; In only 650 large and small cities, the construction of sufficient self-charging equipment will also complete a huge grid renovation project and occupy a large amount of land, which is obviously a serious waste in urban areas where land resources are strained; After the widespread adoption of electric cars, even five minutes of charging time will still cause congestion on nearby roads in the user intensive major cities, and it is obviously impossible to build more intensive facilities. This series of problems, electric vehicles after the popularity of charging difficulties may seriously limit the development of the industry.

It's not as good as a rainy day to fix the charging problem: getting electric cars to "switch batteries" seems like a better option than charging around a charging pile. The establishment of battery rental stores based on population and user density, which are provided by Pre-Charged battery modules in stores for users to replace, can indeed avoid a lot of trouble. According to Tesla, the entire process of replacing battery packs for Models electric vehicles takes only 90 seconds., This greatly reduces user time, improves efficiency, and also reduces possible congestion; Second, compared to recharging stations, the network of battery rental can be greatly reduced, and the cost of land and power grid renovation can also be reduced accordingly. In sparsely populated areas, users can also double the range of vehicles by bringing their own spare batteries, avoiding the shortage of short legs for electric cars. In fact, in Tesla's future plans, its charging station includes battery replacement services.

However, there is still a lot of way to go for the replacement of automotive batteries. On the one hand, each automotive manufacturer is developing its own battery module, and it is difficult to unify standards among them; Under the existing technical conditions, the replacement of batteries is not as simple as household appliances, and professional technicians are required. To solve these problems, I am afraid that the management department's overall planning and technological research and development progress.

In any case, the electric vehicle industry is already on the eve of rapid expansion, effectively solving the problem of supporting facilities, accurately choosing the development path, removing obstacles in the path ahead of time, avoiding falling halfway, and making the entire industry subject to individual problems. I'm afraid this is a management priority. In the past few years, the transportation industry has not developed the low-grade mistakes caused by fewer cars and fewer cars. It should be taken as a warning.
