Hybrid and Electric Vehicle Engineering Academy
I.D. # ACAD06 Duration 5 Days

SAE Engineering Academies provide comprehensive and immersive training experiences, helping new and re-assigned engineers become proficient and productive in a short period of time. The Hybrid and Electric Vehicle Engineering Academy covers hybrid and electric vehicle engineering concepts, theory, and applications relevant to HEV, PHEV, EREV, and BEV for the passenger car industry. While the theory and concepts readily apply to the commercial vehicle industry as well, the examples and applications used will apply primarily to the passenger car industry.

Learning Objectives
Upon completion of the academy, participants will be able to:
  • Define and analyze fundamental electrochemistry of battery operation and performance requirements for HEV, PHEV, EREV and full electric vehicle applications
  • Estimate the size of a cell to meet a specific requirement
  • Create a cradle-to-grave, or cradle-to-use list of materials used in any type of automotive battery
  • Compute the temperature response of battery cell and pack assemblies for a simple model
  • Describe the functions performed by a Battery Management System (BMS)
  • Explain different approaches to estimating state of charge, state of health, power and energy
  • Apply the operation of brushless dc and induction motors to HEV and EV vehicles
  • Define the torque speed curves for motors and the application to electric and hybrid electric vehicles
  • Describe the features of buck, boost, and Transformer converters
  • Compare and contrast the various industry and regulatory standards for hybrid vehicle components, batteries, and charging systems
  • Describe the main hybrid and electric vehicle development considerations and performance requirements for various vehicle system
  • Identify how to define key vehicle system requirements and select and size system components that best meet those requirements
Who Should Attend
Individuals who already have a basic understanding of hybrid and/or electric vehicles who are seeking to increase their knowledge and understanding of hybrid vehicle system applications, including mechanical and electrical application engineers, design engineers, project managers, and other individuals who are working with or transitioning to hybrid-electric powertrain development, will find this academy particularly helpful.

An engineering degree is highly recommended, but not required. This Academy does not cover basic electrical concepts and assumes that the attendee already understands such concepts (voltage, current, resistance, capacitance, inductance, etc.) In order to understand concepts discussed, all participants are required to have driven an HEV prior to attending the academy.

Please be advised that this course may involve one or more of the following: driving and/or riding in a vehicle; participating in a vehicle demonstration; and/or taking part in an offsite tour using outside transportation. You will be required to sign a waiver on-site and produce a valid driver's license from your state/country of residence

Attendees are asked to bring a calculator for in-class exercises.
