Global regulations and rising market expectations are increasing vehicle complexity. As the industry shifts from ICE to fully electric vehicles, test requirements and setups are being redefined. Today, vehicle powertrain testing must go beyond traditional drivetrain and transmission validation – enabling full vehicle testing of high-voltage components such as batteries, onboard chargers, and inverters. For BEVs, driving range has become a central development goal. To optimize it, engineers need a detailed understanding of energy losses across all components. Smart thermal management plays a critical role here, with significant potential to extend driving range. In addition, modern vehicle powertrain test systems must support a wide range of use cases – from performance testing and strategy verification to simulations of special road conditions, failure mode analysis, and the evaluation of electrical accessory performance. The AVL Vehicle Powertrain Test System enables full vehicle testing under various environmental conditions. Wheel hub dynamometers apply realistic, road-like loads based on a vehicle dynamics model, allowing highly accurate and repeatable test scenarios – even during dynamic maneuvers. Direct torque measurement at each hub provides deep insights into energy flow and losses, enabling a detailed analysis of the vehicle’s overall energy consumption. To ensure maximum efficiency, the system integrates the AVL PUMA 2™ automation platform and AVL EMCON 6™ inverter control. Together, they deliver precise, synchronized data acquisition across all subsystems – supporting a wide range of test cases with high accuracy and reliability.
