An e-axle or electric drive unit (EDU) integrates the components electric motor, transmission and inverter. Modern e-axle systems are designed to be very compact, with highest power density, and optimized in terms of efficiency, performance, and driveability. These integrated e-axles are a sub-system where the individual components could not be separated for testing. Thus the test system has to fulfill the requirements and test standards for inverter, e-motor, and transmission testing with regards to service-lifetime, performance, and thermal behaviour.
But how to save time and cost? The challenge is figuring out how much to spend on a specific test system to speed up e-axle development to be productive in testing in the shortest time. Systems must be easy to install without affecting productivity of existing developments, and shall be expandable to meet future demands without a big cost impact.

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 built-to-order solution to develop and validate your light-duty e-axle, regardless of it may be a single motor or a twin motor axle. Shortest delivery time permits you to be productive with in-service lifetime and thermal endurance testing as well as analyzing electrical, mechanical and thermal characteristics. The AVL E-Axle TS™ Performance 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 enables fast and easy handling, and can be used in the outside rigging area. This increases efficiency by reducing testbed down time. Our climatic chambers and conditioning systems enable testing under different climatic and humidity conditions. This type of testing, such as HTOE and PTCE, is mandatory in e-drive development. The integrated DC source in the inverter reduces needed grid power. The solution is designed to be installed in a container. With this pre-tested containerized solution you can start testing within weeks.

AVL Automation
AVL’s powerful 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.”
