Annex 8 – Annex 8 Topics covered by training for persons with prior electrical knowledge in the automotive sector for work in service workshops on vehicles with intrinsically safe HV systems

The topics indicted below serve as an example only and reflect the current state of the art of automotive HV technology. Depending upon the work to be carried out, topics that are not required can be ignored. Other relevant topics must be added in their place if necessary.

Technical responsibility

  • Legal consequences

    (What am I allowed to do? What happens in the event of abuse? No live work!),

  • Control and supervision by a skilled electrical person.

Electrical hazards and first aid

  • Effects upon the human body,

  • Stimulus thresholds,

  • Let-go threshold,

  • Cardiac fibrillation,

  • Burns,

  • Duration of the effect of current upon the human body,

  • Resistance of the human body,

  • Hazardous body currents,

  • Maximum touch voltage,

  • General information on first aid, behaviour in the event of fire,

  • Accidents caused by electric current,

  • Measures to be taken in the event of injury,

  • First aid in the event of injury caused by electric current,

  • Records of first-aid measures,

  • Reporting of accidents.

Measures for protection against electric shock and fault arcs

  • Classification of protective measures; key terms,

  • Protection against direct contact:

    • Protection by the insulation of live parts,

    • Protection by shrouding or encapsulation.

  • Protection against direct and indirect contact (extra-low voltage),

  • Protection against indirect contact (protection against hazardous electric shock in the event of a fault):

    • Protective insulation,

    • Protective separation,

    • Protection by disconnection:

      • Protective device,

      • Electrical system types,

      • Protective measures in the IT system.

  • Function of potential equalization,

  • Testing of the protective measures,

  • Testing of the dielectric strength, for example by on-board or external diagnostics systems,

  • Visual inspection,

  • Checking of the labelling.

Electrical installations and equipment in accordance with the BGV/GUV-V A3 accident prevention regulation and with DIN VDE 0105-100

  • Risk assessment for work on HV vehicles in support of the employer,

  • Content of accident prevention regulation BGV/GUV-V A3, "Electrical installations and equipment", and of the DIN VDE 0105-100 standard governing measures for accident prevention: the first three of the five safety rules

    • Disconnect the HV system,

    • Safeguard against reconnection,

    • Verify the non-live state.

  • Repair, commissioning, maintenance and service - definition of the terms,

  • Measures for troubleshooting on live parts, for example by on-board or external diagnostics systems,

  • Familiarity with possible personal protective equipment and other equipment,

  • Informative safety technology, warning signs.

HV concept and vehicle engineering

  • Introduction to the subject of alternative drives,

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

  • Definition of HV vehicle, explanation of "vehicle with intrinsically safe HV system",

  • HV batteries, power electronics, DC/DC converters, three-phase, synchronous and asynchronous machines, other HV components,

  • Fuel cell vehicles,

  • Hybridantriebe,

  • Electric vehicles.

Allgemeines praktisches Vorgehen

  • HV-System spannungsfrei schalten,

  • Hybrid drives,

  • Spannungsfreiheit feststellen.
