The Design and Implementation of Automatic Battery Swap Stations for Electric Vehicles: A Technical Study Focused on Battery Lifting and Transfer Mechanisms

With the increasing development of technology, people's living standards have soared, and their awareness of environmental protection has gradually improved. This has led to a significant shift in transportation preferences, with the proportion of electric vehicles in private car ownership constantly increasing. Electric vehicles, powered by new energy sources, offer immense market potential due to their eco-friendly nature. However, despite their promising outlook, the path to their widespread adoption in China has not been smooth. Numerous challenges and shortcomings, such as limited battery life and charging infrastructure, still need to be addressed and optimized. Among the myriad of issues hindering the development of electric vehicles, battery charging stands out as a critical concern. When an electric vehicle's battery runs out, the owner is often left with the inconvenience of spending considerable time charging it. To alleviate this issue, the establishment of automatic battery swapping stations for electric vehicles equipped with replaceable batteries has emerged as a viable solution. These stations would enable electric vehicles to swiftly and conveniently replace their batteries, akin to how fuel vehicles refuel at gas stations, thereby minimizing downtime and enhancing user convenience. In this paper, we delve into the functionality of electric vehicle battery replacement and propose a feasible level changer structure scheme. Based on this structural scheme, we meticulously analyze and calculate relevant data to ensure the feasibility and efficiency of the design. Subsequently, we design the battery lifting mechanism and the battery pack transmission mechanism of the electric vehicle level changer.
