Tutorial 1: Energy Storage for BEVs: An Engineering Perspective
Monday, June 17, 2013
2:00 PM – 5:40 PM
Venue: Regency A-B
Instructors: Mr. Ashish Arora and Dr. John Martens
Course Description: Energy storage for hybrid electric vehicles (HEVs) and electric vehicles (EVs) is making a transition from the Nickel-based chemistries to the Lithium ion-based chemistries due to the well-known advantages of relatively lower cost and weight and higher energy density and reliability. Various design topologies and comprehensive battery management systems are implemented to manage the battery system and ensure proper operation. The control topologies utilized are application specific and often require safety circuits with multiple levels of redundancies. The complexity of the circuits is influenced by both the chemistry and size of the battery system. As such, a systems level approach to designing the battery system is used to ensure that the required safety features operate as intended and provide adequate safety, reliability and performance. This tutorial will cover topics including: General battery system requirements for HEVs and EVs, Introduction to the lithium-ion technology and its operation, A comparison of battery chemistries for use in BEVs, Overview of steps involved in the manufacture of Lithium ion cells, Introduction to techniques used for the characterization and evaluation of battery performance, Discussion of the typical design topologies and battery management architectures employed for small and large format lithium-ion batteries, Review of control circuit topologies used to mitigate the safety concerns typically associated with Lithium-ion batteries, Review of typical tests performed on battery systems and discussion of the approach taken by industry standards to evaluate the safety and reliability of batteries used in both HEVs and EVs.
Tutorial 2: Model Based System Engineering (MBSE): The Rise of the Machines?
Wednesday, June 19, 2013
8:30 AM – 12:00 PM
Venue: Regency A-B
Instructors: Aymeric Rousseau and Larry Michaels, Argonne National Laboratory
Course Description: Building hardware is expensive. Traditional design paradigms in the automotive industry often delay control system design until late in the process — in some cases requiring several costly hardware iterations. To reduce costs and improve time to market, it is imperative that greater emphasis be placed on modeling and simulation. Model Based System Engineering (MBSE) approach is meant to increase productivity by maximizing compatibility between systems (via reuse of standardized models), simplifying the process of design (via models of recurring design patterns in the application domain), and promoting communication between individuals and teams working on the system (via a standardization of the terminology and the best practices used in the application domain). But before the machines can take over, numerous issues have to be addressed. The discussion will focus on how Autonomie can be used to support MBSE and some of the remaining challenges. Autonomie is a Plug-and-Play Powertrain and Vehicle Model Architecture and Development Environment to support the rapid evaluation of new powertrain/propulsion technologies for improving fuel economy through virtual design and analysis in a math-based simulation environment. Autonomie is an open architecture to support the rapid integration and analysis of powertrain/propulsion systems and technologies for rapid technology sorting and evaluation of fuel economy improvement under dynamic/transient testing conditions.
