(3BL Media / theCSRfeed) Detroit, MI– February 22, 2012 – Today, the 15 North American universities participating inEcoCAR 2: Plugging In to the Futureannounced the vehicle architectures they will implement in their General Motors-donated 2013 Chevrolet Malibu. The three-year EcoCAR 2 competition, which is sponsored by the U.S. Department of Energy (DOE), Argonne National Laboratory, General Motors, and 20 other government and industry leaders, gives students the opportunity to gain real-world, eco-friendly automotive engineering experience while striving to further improve the energy-efficiency of an already highly efficient vehicle – the Malibu.

But teams don’t get to stop there. Much like the challenges facing automakers, EcoCAR engineering students must balance the challenge of increasing the vehicle’s energy efficiency and reducing the vehicle’s greenhouse gas emissions and petroleum consumption with maintaining the performance, safety and overall consumer acceptability of the original Malibu.

为了应对这些技术挑战，每个ECOCAR团队都设计了自己独特的插电式混合动力电动汽车（PHEV）架构，并利用了众包格式来选择该组件，该组件将在三年计划中将其集成到其先进的技术工具中。该技术模仿行业的全球车辆开发过程，该过程的重点是高级控制和软件以开发未来的车辆。今天道路上的混合动力车已经达到了峰值效率，因此这些团队必须旨在使所有可能的能源从车辆中降低，以减少车辆的环境影响，而不会损害性能，安全性和消费者的可接受性。对15所ECOCAR大学的众多赞助商捐款使这种动手经验成为可能，该大学的软件，硬件和现金捐赠超过了7.45亿美元。

“For this competition, we wanted to donate a vehicle that reflected today’s consumers’ needs, and the new 2013 Malibu made the most sense in terms of its size and flexibility,” said Kent Helfrich, executive director, electronic controls and software engineering, of General Motors. “EcoCAR 2 students will take our Malibu and re-engineer their vehicle to reduce its environmental impact, yet still deliver real-life, practical results. This is not an easy job, but it’s very rewarding. It’s what we do at GM every day.”

“The future in hybrid technology is happening now,” said Patrick Davis, program manager of DOE’s Vehicle Technologies Program. “It used to be that we were on the edge of this type of technology - now we are there, and these students are attempting to take it even further.”

All of the EcoCAR team vehicle designs are PHEVs, which use an on-board battery to reduce fuel use. The battery can be recharged using a standard wall outlet. Once the plug-in range of the battery is depleted, the vehicle can still operate as a regular hybrid. The diversity of architectures the teams have selected rests primarily in the power-flow, which teams will aim to improve upon by using various combinations of fuel, transmission, battery system, electric motor, generator or charger choices. Some teams are even developing their own engine controller.

The powertrain components that the teams have selected to drive the vehicle are five unique combinations:

Parallel through the Road(PTTR) Plug-in Hybrid vehicles utilize electrical energy to power one axle, while an engine drives another axle. EcoCAR 2 teams using the PTTR architecture include: California State, Los Angeles; Purdue University; University of Washington; and Wayne State University.

SeriesPlug-in Hybrid vehicles consist of one or more electric motors driving the wheels, powered by a battery. An engine-generator is decoupled from the wheels at all times and provides supplemental electrical power to drive the vehicle when needed. Teams building a Series PHEV are: Embry-Riddle Aeronautical University; North Carolina State University; Pennsylvania State University; and University of Waterloo.

Series-ParallelPlug-in Hybrid powertrains have the ability to couple and de-couple the engine from the wheels while still providing electric power from the on-board battery to drive a motor. EcoCAR 2 teams using the Series-Parallel architecture include: Mississippi State University; The Ohio State University; University of Tennessee, Knoxville; University of Victoria; Virginia Tech.

Hydrogen Fuel Cell SeriesPlug-in Hybrid vehicles use an onboard fuel cell to convert hydrogen into electricity and either propel the vehicle or recharge a battery pack. The battery pack can be charged using a standard wall outlet. Colorado State University will build a Hydrogen Fuel Cell Series.

Split-ParallelPlug-in Hybrids utilize a motor connected to the engine’s accessory belt that can charge the on-board battery, start the engine and provide additional power for acceleration. A separate motor provides additional power to the wheels. The EcoCAR 2 team using a Split-Parallel powertrain is Rose-Hulman Institute of Technology.

The various architectures will use B20, E85, or hydrogen to extend the range of the vehicles. B20 is a blend of 20% biodiesel and 80% petroleum diesel, and E85 is a blend of 85% ethanol and 15% gasoline.

The first year of EcoCAR 2 emphasizes the use of math-based design tools and simulation techniques for designing a successful vehicle foundation. Each team will receive a 2013 Malibu at the end of the first year of competition in May 2012. In years two and three, students will rebuild the vehicle based on their new architecture and continue to refine, test and improve the vehicle’s operation.
