Abstract- In response to the growing demand for efficient and convenient electric vehicle (EV) charging solutions, this paper proposes a novel ground-based charging system tailored for EV buses and trucks. The system utilizes a current collector mechanism akin to pantograph charging, integrating a linear actuator with three terminals for positive, negative, and ground connections. Pogo pins, each rated at 5 amps and connected in series, are employed as connectors for reliable power transfer. The ground infrastructure consists of buried copper terminals arranged in a grid formation, covered with a silicon inductor sheet to ensure safety and durability. Upon the arrival of an EV bus/truck, a proximity sensor detects its position, prompting the driver to initiate the charging process by scanning a QR code and entering identifying information via IoT communication. Activation of the linear actuator, controlled through a relay system, establishes the power connection between the vehicle and the ground-based infrastructure. Upon completion of charging, the system is deactivated, and the vehicle can resume its journey. This paper outlines the design, operation, and potential benefits of the proposed ground-based charging system, offering a promising solution to enhance the efficiency and accessibility of EV charging for public transportation fleets.
