Improve performance and reduce the cost of electric vehicles.

Learn research-based techniques from a multidisciplinary team at University of Michigan Engineering. Through interactive classroom sessions, you will gain advanced knowledge and learn practical applications in the modeling, design, analysis, and development of hybrid and electric vehicles — with a special focus on electric machines/drives and battery modeling, management, and control.

LEARNING OBJECTIVES

  • Understand the major components of electrified vehicles—principle, current status, technology outlook
  • Become familiar with vehicle control hierarchy and power management algorithms
  • Practice concepts with an example case study on the control and design of power-split hybrid electric vehicle
  • Understand basic operation of electric machines, power electronic inverters, and their control systems
  • Compare/contrast performance of different electric machine types
  • Understand the main functions of the Battery Management System (BMS)
  • Apply electrochemical and equivalent circuit battery modeling techniques
  • Evaluate requirements and specifications for battery systems
