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.
