A Mobile Laboratory as a Venue for Education and Outreach Emphasizing Sustainable TransportationEducators have developed a versatile mobile laboratory that will travel the North Americancontinent serving as a venue for a wide range of educational opportunities including support ofcurriculum based courses, targeted short courses, community education and outreach. The labwas built as part of a US Department of Energy funded program to develop a curriculum inHybrid Electric Vehicle Engineering that include certificates at the undergraduate and graduatelevels.The authors have found hands-on discovery based learning activities to be an effective means ofenabling students to grasp and retain complex topics in engineering and science, andfurthermore, that engineering students excel when they can see how an individual concept fitsthe overall larger context of product development and societal advancement. With an emphasison sustainable transportation systems, the mobile lab provides opportunities for hands-ondiscovery based learning throughout the development process from model based simulation anddesign to optimization of hardware and controls.The mobile lab consists of several elements. The primary laboratory structure is a 53 foot longvan trailer that incorporates an expandable center section for a total of 700 square feet of space.The expandable center section provides for instruction based learning and bench-top activities onfour universal and configurable lab benches. The front and rear of the trailer contain test cellsthat can be operated from the lab benches in a number of modes including a steady state mode tostudy the operation of specific components and as a dynamic system with real-time Hardware-In-The-Loop functionality. The powertrain in the test cells is a match to the powertrain in aconfigurable Hybrid Electric Vehicle. The configurable Hybrid Electric Vehicle allows studentsto change many elements of the vehicle from hardware to embedded software and optimizationparameter sets. Three production Hybrid Vehicles are provided to study the operation ofproduction vehicles in real-world driving scenarios. In addition to driving on the road, theseproduction vehicles, as well as the configurable hybrid vehicle can be tested on the mobile lab’ssingle role chassis dynamometer enabling the students to emulate specific drive cycles.The experimental apparatus and activities on the mobile lab are scalable and configurable. Thisenables educators to tailor the learning experience to many demographics including K-12,college, and the community. Likewise the contact period with the participants can be as short asjust a few minutes in the case of some outreach scenarios, a few days as in the case of some shortcourses, or a full semester in support of curriculum based college courses.This paper provides technical details on the development and capabilities of the mobile lab anddescribes the pedagogy behind the educational activities that are conducted with the mobile lab.The outcomes of select activities are discussed as are ways in which participant assessments areguiding continued development.
