Driven by high fuel prices, environmental regulations, and consumer demand, the market for hybrid electric vehicles (HEV) has experienced rapid growth. Every major automotive company produces an HEV. There are approximately fifty different HEV models on the market and over eight million HEVs already sold. In order to meet current and future demands in the HEV and PHEV markets, success will depend on engineering personnel knowing how to develop and manufacture HEV powertrains.

This two day seminar will cover the fundamentals of HEV powertrain design. The typical architecture of HEVs and the basic functions and modes of a hybrid electric powertrain will be discussed. The seminar will also explain both powertrain design for (P)HEVs as well hybrid transmissions. HEV models such as Prius, Volt, Jeely, Infinity M35h, Jetta, Qin, and BMW i8 will be discussed in case studies.

Learning Objectives
By attending this training program, you will be able to:

  • Recognize the basic layouts of different powertrain architectures for HEVs
  • Explain the functions a powertrain should provide to a HEV
  • Understand what modes an HEV powertrain may work in and shift among
  • Identify the main HEV development considerations for a HEV powertrain
  • Evaluate a powertrain architecture for a certain HEV
  • Recognize an engine or electric motor for an HEV considering the power, torque and efficiency
  • Define a basic transmission for a hybrid transmission
  • Understand how a power coupling mechanism works to switch power flow
  • Identify engineering challenges for developing a HEV transmission
  • Demonstrate basic knowledge of designing a hybrid transmission and its components

Who Should Attend
An undergraduate degree in engineering is highly recommended. Attendees should have some knowledge/experience either in integrating a powertrain into a vehicle, in engineering and manufacturing powertrain for vehicles, or in engineering or manufacturing of transmission/engine/e-motor and the components.

Instructor(s): Zhihui Duan
Mr. Duan is currently Technical Director, Hybrid Electric Vehicles at Chery Automotive, leading a major program of developing a Plug-in HEV, a P2 HEV powertrain being successfully developed, and the PHEV currently in production. Previously, Mr. Duan served as Technical Director of Hybrid Electric Powertrains at Changan New Energy Automobile Inc. China, where he was involved with developing full hybrid electric vehicles and plug-in hybrid electric vehicles. He led a program to develop new generation HEVs and works on power system architecture design, product development, powertrain control, and energy management. He was also involved with developing an Atkinson cycle engine, which improves fuel efficient significantly. Mr. Duan also previously worked with the Sustainable Mobility Technologies at Ford Motor Co., where he was involved in developing new generation hybrid transaxles. He led the effort to fix the transaxle problems that Escape Hybrid vehicles had in the field and to improve quality and reliability. As a result, he was awarded Ford’s Current Model Quality Award: Best in Ford Transmission Warranty Performance. Mr. Duan received his B.S. Aerospace Engineering from Beijing Institute of Aeronautics, a M.S. Aerospace Engineering from Beijing Institute of Technology, and his M.S. Reliability Engineering from the University of Maryland.
