The electric powertrain components electric motors, gearboxes, inverters and traction batteries are subject to the highest quality standards and must be able to fulfill a wide variety of performance and safety conditions. Our Powertrain-in-the-Loop (PIL) dynamometer allows us to realistically simulate all load conditions, and thereby define all parameters needed for the characterization and validation of system components. An integrated e-axle unit with separate side-mounted load and brake motors makes it possible to subject complete drive units consisting of an electric motor, inverter, gearbox, control unit and traction battery to true-to-life driving simulations with authentic road load. In our battery test bench, we can also test and validate everything from individual modules to complex traction batteries for their load and continuous load characteristics as well as their charging and discharging cycles.
