Charging efficiency and battery degradation will continue to restrict the development of pure electric passenger vehicles, and the battery swapping mode is a feasible solution to tackle the above challenges. This paper systematically analyzes the potential advantages and actual predicaments of the battery swapping mode, summarizes the key requirements for the planning and engineering design of battery swapping stations, and designs a ground-sunken battery swapping station. This design will increase the ground clearance of the chassis by three times, providing the necessary space for the automated circulation of batteries and thereby addressing the safety and user experience issues caused by lifting vehicles in traditional battery swapping. In addition, by optimizing the battery compartment plug-in mechanism, the battery capacity and ultimate service capability have been increased by 50% within the same space. The research will elaborate on the system architecture and operational mechanism, explore the technological evolution path, and provide decision support for the large-scale application of battery swapping mode and industrial progress.
