Annex 6 – Annex 6 Topics covered by training for skilled electrical persons in the low-voltage sector

The topics indicted below serve as an example only and reflect the current state of the art of automotive HV technology. Topics irrelevant to the work to be carried out can be ignored. Other relevant topics must be added in their place if necessary.

The following topics must be adapted to the current level of knowledge of the participants.

  • Design and function of vehicle electrical systems,

  • Introduction to the subject of alternative drives,

  • Structure, function and mode of operation of alternative drives:

    • Fuel cell vehicles,

    • Hybrid drives,

    • Electric vehicles.

  • Fuel cell/hybrid vehicles: concepts and operating modes,

  • HV components: e. g. fuel cells, HV batteries, power electronics, DC/DC converters, threephase, synchronous and asynchronous machines, other safety-critical components,

  • Federal ECE Rule 100,

  • Measures to ISO 6469-3 and DIN EN 61140 (VDE 0140-1) for protection against electric shock,

  • Motor Vehicle Safety Standard 305 (FMVSS 305),

  • Recording of energy flows during operation of the hybrid system in various modes,

  • Calculation of body currents in the event of insulation faults; hazards of such body currents,

  • Risk assessment for fuel cell/hybrid vehicles,

  • Protection classes/degrees of protection,

  • Determining the Ri of different NiMH cells,

  • Placing of hybrid vehicles in the non-live state,

  • Measurements on the HV system,

  • Replacement of installed components,

  • Commissioning with determining of the RISO of the HV system with/without faults in the HV system,

  • Measurements (voltage drop and potential) on high-resistance circuits on conventional vehicles in consideration of the Ri of the instrument,

  • Measurement of capacitance and inductance,

  • Measurement of pulse width and frequency on conventional vehicles,

  • Creation and understanding of circuits for transformation of direct current, with and without galvanic isolation,

  • Measurement exercises on hybrid vehicles: location of the components, connection and disconnection of the maintenance plug (service disconnect), checking of isolation, measurement of HV + against HV- and against the vehicle earth,

  • Markings in accordance with vehicle standards/DIN VDE standards/accident prevention.
