VES3.1

VES – Vehicle Energy Systems

Vehicle Energy Systems VES3.1 are specially adapted to test bench operation requirements and features:

  • High dynamics and precision
  • ƒƒQuiet operation
  • ƒƒIntegrated battery models
  • ƒƒPerformance ranges from 10 kW to 1050 kW
  • ƒƒDouble performance by parallel connection at full dynamic
  • ƒƒComprehensive security features
  • ƒƒCustomization for integration into a test bench environment
  • ƒƒCurrent and/or voltage ripple up to 15 kHz
  • ƒƒ40 kHz high speed interface

    Wide Application Range

    Typical operation fields of VES3.1:

    • Battery simulation
    • ƒƒTest of electric motor drives and inverters
    • ƒƒUse as energy drain for fuel cells
    • ƒƒTest of specific electrical components such as a DC/DC converter
    • Battery testing

      Along with high dynamics, these energy systems feature a wide control range and extensive control concept. This allows the VES3.1 to operate various loads with capacitive, ohmic and inductive characteristics. All hybrid components can be tested and simulated. To double the power capacity, two systems can be connected and operated in parallel.

      The use of the latest IGBT technology makes our new systems more silent and compact. Our portfolio of standard vehicle energy systems is rounded off by mobile systems with engine power classes of up to 250 kW.

      Automation and HIL-Simulation

      For the communication between measuring equipment and automation systems we provide all common bus systems. This also covers a fast EtherCAT interface.

      For simulation purposes you have the choice of using onboard models or the possibility to integrate own models. These models can be calculated on FGPA boards with high sampling rate. Therewith, the behaviour of simulated components will be calculated in real time and forwarded to the vehicle energy system as current or voltage reference value. For that purposes, a high speed interface with 40 kHz data sampling rate is available. The MATLAB Toolchain supports model creating with MATLAB/SIMULINK.
