High voltage vehicle technology

Training system for the experimental investigation of original high-voltage components with a focus on troubleshooting: The experiments presented are based on the contents of the currently valid curricula and can also be supplemented as desired.

With the high-voltage system trainer it is possible to simulate insulation faults in the HV cables and components in a simple way. This makes it possible to train and improve systematic troubleshooting with original factory measuring equipment.

In contrast to the original vehicle, all installed high-voltage components are easily accessible. In the event of a fault, only a detectable HV voltage is present, the current-carrying capacity of which is very low. The system provides an overview of all installed HV components that originate from original vehicles.

The work required for disconnection can be carried out identically to the vehicle under simpler conditions. The system trainer removes the daunting complexity of HV vehicle technology through its clear and easy-to-understand structure.

Application and feel correspond to those of the real vehicle.

This equipment is used to perform basic experiments on the following:

• HV battery and HV on-board network 
• Intrinsic safety through the pilot line and potential equalisation 
• HV consumers (electric air-conditioning compressor and electric auxiliary heater) for fault simulation 
• Inverter with HV measuring points 
• Measurement possibility and manipulation of various insulation resistances 
• E-machine connection with measurement possibility at open line ends
