Vehicle energy systems
Used as test equipment in research on alternative energy-storage and drive solutions, our Vehicle-Energy-Systems provides precise and powerful simulation of real sources and sinks.
Application:
- High dynamic voltage supply for drive tests (Battery simulation)
- Generator load (fuel cells,...)
- Energy store testing (HV-battery stacks, supercaps,...)
Properties:
- High dynamic, bi-directional power supply in IGBT-technology
- Mains supply with negligible power quality impacts
- potential separation by medium-frequency transformers
- Output loop controllers with selectable structures and custom parametrisation for flexible test scenarios
- integrated simulation module for emulation of resistors, batteries, capacitors
- continuos transition between source- and sink operation
- quasi silent due to high operating frequencies and water cooling system
- Field bus connectivity: 100µs control cycle by EtherCat or 1ms by CAN
- Extensive protection and safety functions (earth-leakage relay; emergency stop; safety stop; ultra rapid overcurrent, overvoltage and oberheat protection) for device and application safety
