Team Description
Team Tennessee is composed of engineering, business and communications teams. The engineering teams are divided into four subgroups and are categorized by vehicle front mechanical, vehicle rear mechanical, thermal, and controls. John Utley is the overall engineering team lead, and he supports and assists each division of the engineering team. Jacob Wilson assists John as the controls team lead by managing the controls work being done. Emily Wise leads the business team, while Katelynn Routh is overall leader of the communications team.

Vehicle Design
Team Tennessee’s EcoCAR 2 vehicle is a series-parallel plug-in hybrid electric vehicle (PHEV), consisting of a 2.4 L LE9 fueled with E85 (85% ethanol and 15% gasoline) coupled to a UQM SR218H generator. Ethanol is a domestically produced, renewable fuel which has reduced lifecycle greenhouse gas emissions when compared to gasoline. The rear drive consists of a Remy HVH 250-115A motor mated to a BorgWarner eGearDrive. The energy storage system consists of seven 7X15s2p modules from A123 Systems, providing a nominal 340 volts with 40 Ah capacity. The vehicle will have a 55 kilometer charge-depleting range, after which the vehicle may be operated as either a series or parallel hybrid. The series parallel allows for a blended energy consumption strategy which maximizes power efficiency with both series and parallel modes. Series mode allows the engine to operate at the highest efficiency point, and the electric vehicle operation can be carefully brought online to optimize catalyst warming and reduce emissions, while parallel mode is the engine is tied directly to the front wheels. At times of peak power demand, the vehicle will use both series and parallel modes in combination.
