Senior Design 2010 - 2011

Welcome Back!

The Fall 2010 semester at Temple University has begun bringing a new senior design team to work on the Audi TT. We'd like to introduce ourselves briefly:

Stephen Barrett - TU Senior - Mechanical Engineer

Jonathan Childs - TU Senior - Mechanical Engineer

Dean Cun - TU Senior - Mechanical Engineer

Emmy Messina - TU Senior - Electrical Engineer

We will be updating this blog regularly with our challenges, successes, troubles and overall progress on the Audi TT. We feel privileged to be a continuing part of this project and we are excited to get our hands dirty.

Stay tuned!

Project Description

HEATT Team 2010 - 2011:

The transportation industry has yet to find an alternative fuel source with the efficiency and practicality necessary to lower oil use. In order to further this transition, this project bridges the gap between gasoline and fuel cell technology for vehicles. The prototyped power train for this project features a 288 olt battery system combined with an internal combustion engine generator and hydrogen PEM fuel cell to provide addition range. The current state of the power train allows charging for the batteries solely from a house hold socket. The projected range of the battery system is 60 miles; the combined range is 400 miles. To achieve the combine range, the ICE generator and hydrogen PEM fuel cell must be integrated into one system. Our focus is to design a Battery Management System (BMS) to charge the batteries either from a house hold socket, gasoline generator, or hydrogen fuel cell. This would require a charge algorithm that we will have to design. The BMS will be designed and simulated in LabVIEW. The BMS will optimize the performance of the batteries by monitoring the charge and discharge cycles, as well as protect the batteries from power surges and thermal failures.

HEATT Team 2010:

A series hybrid electric powertrain with range extending capabilities using hydrogen and gasoline was designed and modeled in LabVIEW to simulate performance and fuel economy. To prove the concept of this design, a 2000 Audi TT was converted to a plug-in AC electric vehicle with a 90kW electric motor and LiFePO₄ batteries. A 10kW internal combustion generator and 5kW hydrogen PEM fuel cell were installed to extend the range of the vehicle allowing the vehicle to be run easily on today’s fuel and ready for hydrogen, a possible future alternative fuel.

Using the Environmental Protection Agency’s (EPA) standard city and highway driving tests, the vehicle has a theoretical increase in fuel economy from 22/31 miles per gallon (MPG) respectively to 230/173 miles per gallon gasoline equivalent (MPGGE).
