MTS makes available ERS test solutions
Successfully integrating ERS (Energy Recovery System) technologies into a vehicle platform requires considerable development and complex testing. Leveraging its experience in designing and manufacturing ERS components for Formula 1 racing teams, MTS has developed a mean of performing such tests, accelerating the process of ERS integration for any given vehicle.
“With the MTS solution, engineers now have a reliable way to address the challenges inherent in ERS technology development, and to accelerate its deployment into real-world vehicle environments,” said Dr. Rich Baker, Senior Vice President of MTS Test. “Developers can accurately evaluate how different ERS operating strategies affect vehicle performance and efficiency, giving them valuable insight into how to best capture, store and return energy back to the drive train.”
The MTS ERS test solution incorporates a computer-generated vehicle and physical test stations for up to three ERS components, enabling the simulation of a fully integrated vehicle. It is capable of testing components that rotate at angular velocities of up to 120,000 rpm and absorb/generate up to 150 kW. Specimens may include high-speed motors/generators with associated power and control electronics, flywheels, and other energy storage devices such as batteries and ultra capacitors.
The ERS test system provides the flexibility needed to emulate a variety of power electronic converter topologies, control interfaces, and the interface to the full vehicle simulation. This allows developers to evaluate how component-level and overall system performance and efficiency changes with different operating schemes. Specifically, developers can closely study various trade-offs that occur when capturing energy from braking or exhaust; storing it in a battery, flywheel or ultracapacitor; and redeploying it to develop optimum ERS control strategies.
It has taken several years to develop accurate test means for current internal combustion engines. And so far, very few have been accomplished about testing and being able to optimize hybrid systems. I think it will take several more years to have efficient test means for hybrid powertrains including simulated parts. Do you think that today’s capabilities allow to optimize a hybrid powertrain?
