| Objectives: |
By modeling the elements listed below, PSAT enhances DOE's ability to assess the potential of advanced automotive technologies and streamline the development process for promising technologies. PSAT has provided significant benefits to industry vehicle designers and university researchers as evidenced by their growing use of PSAT for both production-oriented and research design activities.
- Vehicle performance, including acceleration and grade
- Drivetrain configuration, including conventional, electric, fuel cell, series hybrid, parallel hybrid, and power split hybrid
- Realistic control strategy development
- Component technologies
- Component sizing

| Technologies Modeled: |
All the technologies that are available in GCTool |
| User Inputs: |
Steady-state fuel cell system models; GCTool-Eng for detailed transient modeling |
| Methodology/Approach: |
Each component is modeled based on physical equations and/or steady-state test data. The data and calculations are written in Matlab, the component models in Simulink and the control strategies in StateFlow. PSAT is a "forward-looking" model that simulates fuel economy and performance in a realistic manner — taking into account transient behavior and control system characteristics. It can simulate an unrivaled number of predefined configurations (conventional, electric, fuel cell, series hybrid, parallel hybrid, and power split hybrid). Because of its accurate dynamic component models, PSAT can be implemented directly and tested at the bench scale or in a vehicle (using its extension for prototyping, PSAT-PRO). This ability supports an ambitious development goal for PSAT — to be transportable from the virtual world of component modeling and simulation to the emulated environment of component control in hardware-in-the-loop (HIL) testing in PSAT-PRO and then to the physical environment of full powertrain control in a vehicle in Argonne's Advanced Powertrain Test Facility. |
| Hardware/Software Requirements: |
Matlab, Simulink and StateFlow. Version R14 is preferred for PSAT V6.1 |
| User Interface: |
GUI has been developed in C# and is provided as an executable |
| Outputs: |
PSAT has thousands of outputs. The most important ones include: fuel economy, performance (acceleration, gradeability). All the component models are characterized by their effort (torque or voltage), flow (speed or current), power, energy and efficiencies. Numerous specific calculations are performed to analyze the vehicle behaviors including, for example, number of engine/fuel cell ON/OFF, percentage regenerative braking recovered… |
| Assumptions Inherent in Model: |
All the component characteristics (power, efficiencies…) as well as vehicle control strategies have to be defined. |
| Sensitivity Studies Facilitated: |
Fuel cell system power; vehicle mass; fuel cell system efficiency; vehicle frontal area |
| Timeframe Studied: |
2006 - 2050 |
