Fundamentals of Hybrid Electric Vehicles     


I.D.# C0511Printable Description
Duration: 3 Days

One of the fastest growing automotive fields, hybrid electric vehicles (HEVs), presents both opportunities and challenges. HEVs are more fuel-efficient and environmentally friendly compared to conventional vehicles. Optimizing the power intake in HEVs allows the engine operation to be kept within the range designed for best fuel economy and lowest emission, while the motor/generator system either provides additional power input, or generates electricity using the excessive power from the engine. It also recovers the kinetic energy during braking or coasting. These advantages have attracted worldwide development interests for HEVs in the automotive industry. Global sales of hybrid vehicles continue to grow and experts predict that 38 models will be available by 2011.

The challenges presented in HEVs include power electronics, electric motors and generators, batteries, power management, thermal management, and system integration. Additional challenges related to after-sales issues include reliability, gracefully degradable operation, and servicing.

This three-day seminar will cover the fundamentals of HEV. In an easy-to-understand format, the course will explain the engineering philosophy of HEVs, the component selection and design, modeling, and control of HEVs. Some existing HEV models such as the Toyota Prius, Honda Civic, Mercury Mariner, Saturn VUE and Camry will be used as case studies.

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

  • Describe the pros and cons of different types of HEVs
  • Implement fundamental HEV design parameters

  • Develop models and perform simulations of HEVs; simulate the fuel economy and emissions of HEVs
  • Size a HEV powertrain
  • Size HEV components, including motors, energy sources and motor controllers
  • Calculate the regenerative braking performance of a HEV
  • Describe the testing procedures for HEVs
  • Compare and contrast hydraulic hybrid and electric hybrid systems
  • Discuss the emerging technologies, engineering challenges, and development trends in HEVs

Who Should Attend
This fundamental overview course is designed to provide an introduction to HEVs for engineers in electrical, mechanical, automotive and other related fields who are involved or interested in HEV development, design, modeling, manufacturing and marketing.

Attendees should have a basic understanding of electrical engineering systems, some mechanical system background related to equations of motion, or experience with automotive engineering.
