Team Vision for Problem Definition Phase

Our team expected to fully define the scope of the problem during this phase and to be able to move forward with researching for system design.

We identified important parameters of the project, such as the overall project goals, important project stakeholders, customer requirements, use scenarios, house of quality, engineering requirements, top risks, and a project schedule for the next three weeks.

Project Summary

An important aspect of today’s new hybrid and electric vehicles is the thermal management system. This system ensures proper vehicle function and helps avoid decreased drivetrain efficiency, battery wear, and safety hazards. This not only holds true for commercial electric vehicles, but it is also important for Formula SAE electric vehicles. On the previous RIT Hot Wheelz vehicle the system consisted of ineffective air vents and heatsinks to cool the electrical components.

The goal of this project is to deliver an efficient thermal management system for the RIT Hot Wheelz Formula SAE Electric team’s 2016-2017 vehicle. The current system was not a priority of the design of the vehicle, nor was any testing performed on its effectiveness. The expected end result is a data-driven lightweight system that optimizes the vehicle’s performance through effective cooling methods for the electrical powertrain. The system should comply with all Formula Hybrid regulations as well as the constraints of the current vehicle design.
