Tentatively, the morning tutorials will start at 8:30 AM and conclude at 12:00 noon, with a 35-minute break from 10:10 AM until 10:45 AM. The afternoon tutorials will start at 2:00 PM and conclude at 5:30 PM with a 35-minute break from 3:40 PM until 4:15 PM.

 

Tutorial 1: Battery Technologies  
Tuesday, September 6, 2011, 8:30 AM – 12:00 Noon  
Venue: Clark Room

Speaker: Oliver Gross, Chrysler LLC, USA

Tutorial Description: This tutorial will introduce the participant to the major electrochemistries utilized in automotive batteries. Battery applications will span low voltage and micro-hybrid systems, up to full electric vehicles. The participant will learn about the major factors determining battery size and configuration for multiple electrified powertrain applications. Materials selection, cell and battery design topologies for the more advanced (Nickel-Metal Hydride and Lithium-ion) technologies will be presented.  Key factors governing life and durability, as well as battery control methodologies will be addressed. Finally, the participant will be introduced into battery safety and abuse considerations.

  

Tutorial 2: Object Oriented Modeling and Simulation of Electric and Hybrid Electric Vehicles with Modelica
Tuesday, September 6, 2011, 8:30 AM – 12:00 Noon  
Venue: Columbus Room  

Speakers: Thomas Bäuml and Markus Einhorn, Austrian Institute of Technology, Austria

Tutorial Description: Shrinking sources of oil and gas and the concern about green house problems has made the development of hybrid electric vehicles or electric vehicles a very prosperous field of application. Pushing the utilization and the efficiency of each component, simulation has become a necessary and powerful tool. Because of the massive interconnection between different physical systems in a vehicle, not only simulations on component level, but on the whole vehicle system level are of greater importance than ever. Best performance of the vehicle can only be achieved if it is regarded as one system and optimised components are working in an optimised environment. Therefore a multiphysical simulation approach is inevitable. Optimizing heat flows between electric machine, battery and passenger cabin is a challenging task as well as determining the feedback from the drivetrain to the electric circuit. The tutorial gives an overview about object-oriented, component based multiphysical modelling by means of the powerful Modelica simulation language (http://modelica.org) and its associated technology. With Modelica a whole range of application areas can be represented and it thus can be seen as an almost universal approach to high level computational modelling and simulation. It provides general notation as well as powerful abstractions and efficient implementations. In the tutorial the usability of Modelica for modeling and simulating electric and hybrid electric vehicles will be demonstrated on some basic application models which will then be assembled to an electric or hybrid electric vehicle model. Furthermore more detailed application examples will be shown to demonstrate the complexity and applicability of the simulation environment.

 

Tutorial 3: Autonomie: Next Generation Vehicle Software  
Tuesday, September 6, 2011, 2:00 PM – 5:30 PM  
Venue: Clark Room

Speakers: Aymeric Rousseau and Larry Michaels, Argonne National Laboratory, USA

Tutorial Description: Because of time and cost constraints, designers cannot build and test each of the many possible powertrain configurations for advanced vehicles. Thus, developing conventional, hybrid electric vehicles (HEVs), and Plug-in HEVs (PHEVs) requires accurate, flexible simulation tools.  Based on more than a decade of experience acquired in developing PSAT (Powertrain System Analysis Toolkit) to assess the performance and fuel consumption benefits of advanced vehicles, Argonne National Laboratory has developed the next generation of vehicle simulation tool in collaboration with General Motors. Autonomie has been developed to accelerate the development and introduction of advanced technologies through a Plug & Play architecture. Autonomie has been designed to be used as a single tool throughout the Vehicle Development Process by promoting reuse and exchange of models and supporting Model Based Design approaches. This tutorial will demonstrate the advanced functionalities of Autonomie and its models and will tackle the following topics: load and run existing vehicle models, from conventional to hybrid to electric drive (HEV, PHEV, EV); analyze fuel economy and performance results as well as detailed component operating conditions; modify existing models, files and parameters; select and use processes (i.e., drive cycles, performance tests, procedures…); understand models and control strategies; create vehicles from existing systems; run vehicles outside the GUI for development; and customize the tool, including proprietary data, proprietary models, and linkage with Subject Matter Expert tools (i.e., GT-Power, AMESim, CarSim).

 

Tutorial 4: Hybrid Electric Powertrains  
Tuesday, September 6, 2011, 2:00 PM – 5:30 PM  
Venue: Columbus Room

Speaker: Mengyang Zhang, Chrysler Group LLC, USA

Tutorial Description: This tutorial covers fundamental aspects of modern HEV powertrains, from characteristics of subsystems to vehicle level requirements pertaining to powertrains. The technical details about HEV vehicle performance, drivability, fuel economy, emission standards and OBD compliance are elaborated. HEV operating strategies and controls are explained in the light of meeting powertrain requirements. Examples from some of popular HEV models are used to explain the current state of art of HEV powertrains. Potentials and challenges of PHEV and EREV are also discussed.
