The electrification of mobility is experiencing significant growth, enabled by improvements in the efficiency of drivetrains that increase vehicle range and performance. E-motors, inverters, and complete drivetrains need to be tested, analyzed, calibrated, and subsequently optimized to push their performance to the limits of what is technically possible.
- In-depth analysis of electric drivetrain and power electronic components such as e-motors, inverters, and dc/dc converters
- Testing and optimization of complete e-drives on testbeds
- In-vehicle testing for energy flow analysis under varying climatic situations on the dyno and on the road
Energy Flow Measurement
Testing on-road and on-dyno with high number of channels for full system analysis.
Dynamic Testing
Power calculation down to a single cycle for best dynamic analysis of transient changes.
Rotor Position Flexibility
Interfacing with different types of rotor position sensors for rotor-dependent results.
Hybrid Testing
Modular layout enables hybrid testing of NVH or indicating with a synchronized time base.
Raw Data Recording
Streaming and recording of signal and result data for seamless analysis of each test run.
HiL Optimization
Real-Time output for optimization of e-drives in a hardware in the loop setup.
The AVL X-ion e-Power front end modules (X-FEMs) filter and sample electrical voltages and currents at high speed (2 MS/s) and with high resolution (18-bit). Digital filtering is performed in the X-FEM with result processing being conducted in the X-ion base unit. The result data and optional raw data are streamed to the AVL IndiCom™ PC software for storage and display. The software offers a wide range of options for post-processing and interfacing to automation and application systems.
Alternatively, results can be output from the X-ion directly to CAN or EtherCAT for use in application systems.

AVL has a wide portfolio consisting of dedicated e-motor test systems, software, tools, and processes to test and validate these modern e-drive systems in shortest time and with highest quality standards.
The inverter is very complex, and its behavior and handling influence the driving experience significantly. It needs to be tested and developed without further influences of other components. Learn more about our test system (TS) for inverter.
The Electrochemical Impedance Spectroscopy (EIS) is an innovative stimulus response testing technology for checking the frequency-dependent internal resistance of electrochemical cells such as batteries or fuel cells.
AVL IndiCom™ is a comprehensive software platform for data acquisition and signal processing tailored for mobility and energy sectors. The applications are e-power, combustion, EIS, or NVH analysis.
WEBINAR - State of the art e-mobility testbeds raise the requirements to high-speed data acquisition devices, especially in the field of power measurement, which lays out the base for efficiency analysis of components and drivetrains or tuning of inverters.
WEBINAR - The core of our solution to handle module tests as well as the analysis of entire powertrains in a lab, on test beds, chassis dynos and even on the road, is a diagnostics platform system: small, dedicated sensor – recorder units combine into multichannel recorders and data interfaces.
WEBINAR - In this webinar, AVL provides an overview of the power measurement with the AVL X-ion™ e-power analyzer on an inverter testbed. Today’s variety of different powertrain topologies in development challenges the testing and calibration of traction inverters within those.
WEBINAR - Testing methodologies in the field of power electronics are continually improving to cope with increasing challenges, like higher switching frequencies in modern vehicle semiconductors and the specifications contained in the LV123 electrical test standard.
