CarTrain "Hybrid and Electric Vehicles"

Trainees work directly on a real high-voltage system, which has nevertheless been adapted with special safety features so that it can be used without any prior qualifications. Thus this training system provides a safe work environment and allows students and trainees to fully focus on the task at hand. All the content is based on the DGUV 200-005 standard (levels 1 and 2) or even exceed these requirements. Trainees can become familiar with all the key theoretical background by means of an interactive e-learning course. Each of the theoretical sections is accompanied by practical exercises and tests of knowledge, which also help to advance vital diagnostic skills. These skills are further boosted by the built-in diagnostic system and the scrupulously selected fault scenarios. This is the only training system which gives students the opportunity to develop various diagnostic strategies involving measurements on an actual HV system with real HV voltages under the most stringent safety conditions.

Special features of the training system:

  • High-speed CAN as communication bus integrated into the HV system control.
    • Communication between HV charging system, HV battery and inverter.
    • Voltage values read out as CAN messages.

Set-up of the training system

  • On the front there are two motor-generator units and two transmission systems which transfer drive power to the two wheels on the rear axle.
  • Different overlay masks are used to depict the various types of drive and vehicle. In addition to the graphic representation of the relevant block circuit diagrams, direct measurements covering individual electrical components and the flows of energy between them can be made with the aid of the diagrams themselves.
  • A capacitive colour touch panel, 10.4 inch, offers a view of the instrument cluster for the vehicle in question.
  • The touch panel can also be used to invoke the built-in engine tester.
  • Also on the colour touch panel, force and energy dynamics can be shown as animations which are based on the original vehicles themselves.
  • A potentiometer can be used to reset the speed of the vehicle as required.
  • Another potentiometer enables the energy available from the HV battery to be adjusted between 0% and 100%.
  • The driving profile is changed between uphill, level and downhill road conditions using a switch.
  • The vehicle is started using a 3-stage ignition switch.
  • The system is equipped with batteries connected in series, in order to clarify the principle behind series connection of the traction battery.
  • A service maintenance plug (incl. interlock contact) is located on the front panel in order to de-energise the high-voltage system.
  • Measurement sockets to enable verification that the system is de-energised (voltage free) are located behind a lockable cover (incl. interlock contact).
  • There are also externally accessible 4-mm measuring sockets directly connected to the resolver. Sine and cosine voltages from the resolver can thus be measured directly.
  • 4-mm measuring sockets are also accessible for equipotential bonding.
  • Other 4-mm safety measuring sockets are provided in order to measure screening of the wiring.
  • There are also externally accessible 4-mm measuring sockets directly connected to the inverter.
  • Measuring sockets for motor/generator 1 are provided in the form of 4-mm measuring sockets.
  • Measuring sockets for motor/generator 2 are provided in the form of 4-mm measuring sockets.
  • A fully functional type 2 charge terminal for connection to a charging station conforming to IEC 61851-1 is also installed.
  • Measuring sockets for demonstrating safety communication between the charging station and the vehicle via an interlock contact are also available in the form of 4-mm safety measuring sockets.
  • To aid faster understanding, the right-hand side of the front panel features a graphic representation of each drive configuration implemented in the system.
  • An emergency stop switch is also located on the front panel.
  • The system as a whole can be connected to a PC with the help of a USB cable. A built-in measuring instrument allows all measurements on the system to be recorded and sent to the computer via the USB link.
  • A lockable fault simulation switch box makes it possible to emulate an extensive variety of fault scenarios.
  • Measurements of insulation resistance can also be made using an instrument which is supplied with the training system.
