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
