E-Truck System Definition and Modeling

The E-Truck project is an interdisciplinary four-year student led project to convert a diesel powered medium-duty commercial truck to an Electric Vehicle (EV). To successfully complete this conversion, this student team will need to determine the performance parameters of the EV that the team is going to design. In other words, this student team will need to work to determine realistic and firm design goals. This student team will first work to learn about the performance characteristic of diesel powered medium-duty commercial trucks. This will be followed by a comprehensive study of what would be required from an electrically powered truck for it to be accepted by the marketplace. This student team will use this information to select the design requirements in terms of performance parameters for the converted truck. The student team will work to determine design goals such as maximum payload, range, typical use, weight, acceleration, brake performance, cost of vehicle, service life, cost of operation, safety, etc. In order to meet this goal, the team will need to work to: - understand vehicle sub-systems and overall logical architecture. - model functional and physical architecture of the new system. - explore relevant properties to define system performance and implications - develop initial requirements drafts to articulate system goals. The outcomes this student team is working to achieve include: 1) System Modeling Language (SysML) of Electric Truck architecture. 2) Requirements specifications for stakeholders and system.
