The Challenges of Designing Electrical Systems for Really Big Zero Emission Vehicles Thursday, September 19, 9:55 AM

Guest Speaker Mr. Fowlkes will describe the challenges in designing an electric passenger bus capable of fully recharging in less than 10 minutes.

Advanced EDS Design Tools Helping to Answer Tomorrow's Demand for Fully Electric Vehicles Thursday, September 19, 1:30 PM

Technical Session Electric and hybrid vehicles pose design challenges beyond those of conventionally powered vehicles. Technical challenges include modelling battery charge / discharge cycles, critical safety-related issues, and managing electromagnetic effects. This presentation describes these challenges and shows how modern electrical system design software can help address them.

Connecting Domains: How Software Components Can Influence Electric and Hybrid Vehicle Architectures Thursday, September 19, 4:20 PM

Technical Session Understanding how decisions are made in one domain and how these decisions can affect behavior in another domain is an important aspect of system engineering. This is particularly true when it comes to creating effective designs with a high overlap of electrical and electronic components, such as in electric and hybrid vehicle design. This session demonstrates how optimized design decisions can be made by providing insight into how software/ECU/network architecture choices impact electrical implementations in terms of cost, weight, and space reservation.

  • An Integrated Tools Environment for Modeling Integrated Powertrain Systems
    Toggle Abstract

    TECHNICAL SESSION When designing systems that include motors, power electronics,and/or sensors and controls (electronics and software), waiting to verify overall performance using a physical prototype is unacceptable. Finding problems late in the development process not only has cost and schedule impact, but debugging these complex designs with limited “system-level-only” visibility is difficult. Fortunately, virtual prototypes can be used to help make critical design decisions earlier in the design cycle, to size and integrate components from various disciplines, and to verify system performance prior to building any physical hardware.

    This presentation describes a modeling and simulation development environment that supports progressive refinement of system models, from abstract to high-fidelity. It demonstrates virtual integration of Permanent Magnet Synchronous and/or Induction Machines (PMSM or IM); digital, analog and power electronics; and plant mechanical dynamics (all modeled in SystemVision from Mentor Graphics), with embedded control software (modeled in Simulink® or C-code) and a complete system test program (modeled in LabVIEW™). In addition, it shows FEA-based design software being used to analyze a machine’s physical geometry and material properties, then automatically generating an accurate behavioral model that can be simulated in the system context. This model can help identify adverse interactions with the motor and the power electronics or sensor signal conditioning circuits. This approach helps engineers gain confidence in a design before committing to a specific implementation. Tool flows that then lead to physical implementations (e.g., PCB, cabling, mixed-signal ASICs, and embedded software) are also discussed.

  • Battery Pack Thermal Design – Accessing CFD Results Earlier in Development to Understand Packaging Changes Influence on Cooling Capacity
    Toggle Abstract

    TECHNICAL SESSION As Battery Electric Vehicles and Plug-In Hybrid Electric Vehicles become more and more prevalent on the market, battery temperature control remains a major vehicle thermal management focuses. Controlling battery temperature is a key in a vehicle operating efficiency and battery life. Although not as high a cooling capacity as a liquid cooling system, lighter weight, more reliable, and less expensive passive air cooled system are often preferred choice in compact vehicles.

    This presentation introduces the value in performing cooling analysis using fully CAD Embedded Computational Fluid Dynamics (CFD) to allow earlier thermal performance prediction such as when deciding the battery packaging and intergrartion with the vehicle structure. A passive air-cooled battery pack system example is simulated, using FloEFD software in a major CAD environment, to quickly study the effects design changes have on cooling capacity in order to maintain proper mean temperature and appropriate temperature distribution.

  • To Build a Better Electrical Distribution System, Start with Simulation
    Toggle Abstract

    TECHNICAL SESSION Can simulation really help you build a better electrical distribution system? You may be surprised to learn that the answer is “Yes!”. Join this session to learn how you can use simulation early in the wiring development process to establish practical rules and constraints for distribution system design. Using an Alternator Load Dump example, we will illustrate how important design constraints, such as fuse and wire sizing requirements, are easily determined for a multi-voltage (48V/14V) system. This design example models important electrical system behavior, including alternator electro-dynamics, voltage regulation, battery state-of-charge, and system loading. Simulation of this system model shows the realistic high-voltage transients that occur when the battery is disconnected from the electrical system during heavy charging. During this session, you will learn how to analyze these transients to define requirements that drive the downstream electrical distribution system design process.
