An e-axle or electric drive unit integrates an electric motor, transmission, and inverter into a compact, high-power-density system. Optimized for efficiency, performance, and drivability, these integrated e-axles present a challenge in testing, as the components cannot be easily separated. The test system must meet service lifetime, performance, and thermal behavior standards for all three components.
To save time and cost, the test system should streamline e-axle development and be easy to install without disrupting ongoing projects. It should also be expandable to accommodate future demands while minimizing additional costs.
Minimized TCO
Pre-engineered solution to be productive in testing as soon as possible.
Increased Efficiency
Accelerate your productivity with a seamless integration of all tools including the automation system.
High Sustainability
Systems are build with regards to use minimum electrical grid power.
Predictive Maintenance
Efficient test planning with predictive maintenance.
The AVL E-Axle TS™ Performance is a customizable solution to develop and validate your light-duty e-axle, supporting both single and twin motor configurations. It offers efficient testing for service lifetime and thermal endurance, as well as analyzing electrical, mechanical and thermal characteristics.
The System consists of two dynamometers as load system which are installed on one common frame. This frame does not require a specific testbed pit and can be set up on any industrial floor.
The UUT support frame allows quick handling, reducing testbed downtime, while climatic chambers and conditioning systems enable testing under various conditions. With an integrated DC source in the inverter to reduce grid power needs, the system is pre-tested and ready for containerized installation, enabling rapid testing setup.

AVL Automation
Our powerful AVL PUMA 2™ automation system allows systematic e-axle testing for a wide range of applications. It enables precise measurement and closed-loop control of key parameters such as speed and torque.
Energy Efficiency
Modern converter technology allows the integration of a galvanic isolated DC source to supply the power electronics of the e-axle into one drive cabinet. This reduces footprint and grid connection power.
Environmental Tests
Our climatic chambers and conditioning systems enable testing under different climatic conditions. This is mandatory to fulfill test standards such as HTOE and PTCE in e-drive development.
With our in-house engineering department, we closely evaluate and actively shape the market and innovations in order to provide our customers with the best possible advice and support. Based on this application know-how, we develop e-axle test system solutions that ensure our customers achieve their development goals sustainably and efficiently.”

Based on years of experience in research and development, as well as production, we have developed AVL E-Axle TS™ Production. It provides End of Line (EOL) and Conformity of Production (COP) testing for electric drive applications, from passenger cars to high performance vehicles, as well as industrial applications.
Battery packs, modules and cells, fuel cells, e-motor and e-axle solutions must operate safely and reliably in any environment. This can include extreme temperatures and humidity, which cannot be reproduced on the test track or in real test scenarios on the road. This is why we developed the modular AVL Climate Chamber.
Thermal conditions and environment of Units Under Test have strong impacts on real results in driving. For this reason, the thermal simulation must be as exact as possible – which can be achieved via deployment of high performing media conditioning systems.
The AVL Customer Services organization consists of more than 700 service- and application engineers worldwide, operating from more than 50 locations. Our global footprint is your local benefit.
AVL List GmbH received the Global EcoVision Award from WKÖ in the presence of Federal Chancellor Karl Nehammer, Federal Minister Martin Kocher, and WKÖ President Harald Mahrer for the achievements in Hungary.
What kind of cars will we be driving in the future? These and other exciting questions around the topic of "Future Mobility" were addressed by more than 1,000 participants from 25 countries at the international 44th Vienna Motor Symposium. The tenor: Future automobiles will be CO2-neutral.
For his services, Prof. Helmut List was today awarded honorary citizenship of the city of Graz.
AVL generated 1.86 billion Euros in turnover last year – Eleven percent flows into research and development – 60 percent of the turnover is already generated by new technologies.
