Lab Spotlight: TARDEC’s Power & Energy Vehicle Environmental Lab



The U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) Power & Energy Vehicle Environmental Laboratory (PEVEL) is equipped with multiple dynamometers that provide the integrated tools required for full vehicle powertrain testing, evaluation and assessment on wheeled and tracked vehicles through external load control and data collection. Program Executive Offices, Program Management Offices, manufacturers, academia, and researchers are actively using these tools to create, assess, and validate vehicle design, functionality, and utility in a fully controlled and repeatable lab environment.

The PEVEL chamber’s unique capabilities enable testing at temperatures from minus 60 degrees F to 160 degrees F, and humidity levels from 0 to 95 percent relative humidity, making it possible to produce real-world vehicle performance and capability comparisons. The PEVEL can generate wind speeds up to 60 mph and a solar load up to 1,200 W/m2. Additionally, the PEVEL can process electrical power up to 800 kW, wheeled vehicle torque up to 34,000 lb-ft, and tracked vehicle torque up to 42,000 lb-ft. Compatible fuels for testing in the PEVEL include hydrogen, DF-s, JP-8, JET-A, bio-diesel, and synthetic blends.


  • Functions as a testbed to evaluate vehicle system performance in any operational environment.
  • Allows for testing in extreme climates under various loads.
  • Performs repeatable tests on components or vehicles, producing real-world vehicle and component performance/capability comparisons.
  • Functions as a systems integration laboratory; fully supports hardware-in-the-loop simulation.
  • Addresses the testing gap for multi-axle wheeled vehicles and provides additional evaluation capabilities for vehicle on-road performance.
