Electric Drives
By combining the overall knowledge of the powertrain system with specific qualifications in power electronics and high-voltage technology our engineers cover a wide spectrum of topics in the development of (partially) electrified drives:
- Design of (partially) electrified powertrains regarding performance, power, longitudinal/transverse dynamics, transient response, consumption, emissions, range
- Validation of system requirements for HV systems
- Efficiency issues in hybrid topologies
- Creation of HV test specifications for electrical drive components (electric motors, power electronics, HV batteries, onboard power systems)
- Application of electrical drives on the test bed and in the vehicle
- Development of algorithms for models and characteristic diagrams
- Consumption studies and emission control testing on hybrid vehicles
In addition to overall system tuning we also have specific know-how in the design and validation of individual components:
- Characterization and failure analysis of electric motors and converters e.g. examination of torque ripples
- Development of electrical and thermic stress scenarios for safeguarding the temperature stability of cables and contacts
- Ensuring the state of charge balance/SoC of the electric storage
- (Pre-)development of HV onboard power system components
- Mechanical component back-up/load spectrum measurement
- Construction of thermically optimized battery casings
- Modelling/simulation for cooling systems for HV batteries
- NVH analysis of electrical drive component
