Analysis of the Advantages of the Battery Swapping Mode under the Vehicle-to-Grid Interaction

Abstract

As the world advocates the development of new energy, the holding quantity of electric vehicles continues to rise, so the vehicle-to-grid interaction has become one of the key topics of today's research. Researchers regard electric vehicles as an adjustable mobile energy storage device that interacts with the power grid for energy and information. However, there is still a research gap on whether the battery swapping mode is more suitable for vehicle-to-grid interaction than the battery charging mode. Therefore, this study will collect data to compare the economic, convenience, and technical aspects of battery swapping and charging. It is concluded that charging and battery swapping are not much different in terms of economic attractiveness to users, but their convenience is greatly improved. At the same time, battery swap stations, as distributed energy storage units, have a better peak shaving and valley filling function for vehicle-to-grid interaction. However, the size and compatibility of batteries and the universality of battery swapping modes still need further research.
