Systematic assessment of a very large number of technology combinations including uncertainties

Increased vehicle and powertrain technologies options have increase the reliance on system simulation to assess their impact on energy consumption, performance and cost. When considering the number of vehicle classes (from light to heavy duty), powertrain options (e.g., conventional, start-stop, HEVs, PHEVs, BEVs, FCEVs), component technologies (e.g., transmission types, gear number/ratios) and vehicle technical specifications (e.g., 0-60mph, gradeability, startability…), the number of potential vehicle design is in the millions!

Over the past 20 years, Argonne has developed an automated end-to-end workflow to assess technology impact on vehicle energy consumption, performance and costs

  1. Advanced powertrain: include all powertrain designs currently in production or planned
  2. Advanced components: collect performance data for any current and future technologies (e.g., 25+ different engine technologies currently included)
  3. Advanced control: control algorithms and calibration developed from individual vehicle dynamometer testing (Sample data – Downloadable Dynamometer Database)
  4. Automated model building: Since millions of design options are possible, the system models are build automatically
  5. Powertrain sizing: automatically size the components (power, energy…) to meet the VTS
  6. Launch all the simulations on HPC
  7. Perform automatic QA/QC and analysis
  8. Use individual vehicle simulation outputs to develop Autonomie AI
