Design for implementation : fully integrated charging & docking infrastructure used in Mobility-on-Demand electric vehicle fleets

Abstract

As the technology used in electric vehicles continues to advance, there is an increased demand for urban-appropriate electric charging stations emphasizing a modern user interface, robust design, and reliable functionality. Publicly shared transportation systems provide electric vehicles with further synergies by allowing for less energy consumption per capita and decreased car congestion. Unfortunately, existing charging platforms are not designed for proper adoption in a public setting and tend to be vulnerable to potential safety hazards and vandalism. Our product, smartCharge, addresses the need for electric charging in a Mobility-on-Demand transportation system. The connector interface design proposed allows for a modular approach for charging various publicly shared electric vehicles, while using a current-controlled locking mechanism with up to 250 pounds of force. Additionally, the connector is linked to the charging post through a stainless steel retractable arm, which is composed of a spring-loaded pulley mechanism. This paper discusses the design and manufacturing processes for the charging connector and retractable arm, while elaborating on the overall functionality of smartCharge. Finally, the implementation strategy and key considerations for deploying this technology are briefly discussed.
