The advantages of battery swapping technology are as follows: 1. It can shorten the time required for energy replenishment. Under normal battery swapping methods, battery swapping only takes 3 to 5 minutes, which is similar to the time it takes for a gasoline powered car to refuel.
This significantly shortens the time required for electric vehicles to replenish electricity, shortens the waiting time for car users, and greatly improves the utilization rate of new energy vehicles.
For applications such as public transportation, taxis, and ride hailing services that require frequent charging, the advantages of battery swapping technology are more pronounced.
2. Reduce the cost of purchasing cars for car users, eliminate their doubts and concerns about the quality assurance of car batteries, and eliminate the fact that the manufacturing cost of car power batteries accounts for about 40% of the total cost of electric vehicles. In fact, car users only use 20% to 30% of the battery life value during the driving process.
With the application of battery swapping technology, car users can rent car power batteries, and through this method, the supply of car electricity can reduce the purchase cost of car users in the early stages of use.
3. Extending the service life of automotive batteries. Although fast charging of automotive power batteries can shorten the time required for energy replenishment, the use of DC fast charging can reduce the number of charging and discharging cycles of automotive power batteries to a certain extent due to the large amount of current required.
Accelerate the reduction of car battery capacity, which in turn affects the performance of car batteries and shortens their service life.
The battery swapping technology stores the car’s power battery in a charging warehouse, which can slowly charge the car battery and exchange it for a depleted battery for continuous slow charging after the battery reaches saturation.
At the same time, a battery swapping warehouse with integrated battery detection and maintenance functions can detect whether the status of each replaced battery is normal.
Objectively reducing damage to automotive power batteries and reducing battery capacity can extend the service life of automotive batteries to a certain extent.
The main technology for electric passenger cars during battery swapping now is to use a fully automatic overall chassis battery swapping method. Representative car companies include BAIC New Energy EU System, SAIC Roewe Ei5 model, and NIO.
The battery swapping technology is mainly used in the following fields: 1. The mainstream battery swapping models in the electric taxi field include BAIC New Energy EU300 and SAIC Roewe Ei5 quick swapping versions, both of which are provided by Aodong New Energy with battery swapping stations and technology.
2. In the field of private cars, NIO is currently a leading enterprise in the field of new energy private car battery swapping. NIO’s current models only support battery swapping technology.
Now NIO’s battery swapping station is also self invested and self built, providing battery swapping services for automotive users.
The battery swapping technology in the field of heavy truck operation also plays a crucial role in the electrification process of heavy trucks.
Overall, at this stage and in the future, the two modes of battery swapping and charging will coexist for a long time.
Battery swapping technology can overcome the long-standing drawbacks of high purchase costs, long charging times, and high cost of scrapping and updating power batteries in the development of pure electric vehicles.
With the development of battery swapping technology, the standards for automotive batteries are becoming increasingly unified, and battery swapping technology will play an increasingly important role.
