Les experts ZF Haute tension

Qualification en tant qu'expert Haute Tension ZF

Devenir un expert ZF haute tension n'est pas compliqué si vous avez une réelle motivation et l'envie d'effectuer la maintenance sur des véhicules électriques et hybrides dans votre atelier.


Votre parcours de formation dépend de votre formation initiale. En fonction de vos qualifications, votre formation changera. Par exemple, si vous avez des connaissances en génie électrique, vous aurez à suivre une formation pour atteindre la qualification niveau 2.

Quels sont les niveaux?

DGUV Info 200-006

The DGUV Info 200-006 is a great document for employers and supervisors, because you can see exactly which qualification requirements are necessary for specific work on high-voltage vehicles. However, you must bear in mind that this is not a regulation or law – rather, it is designed to help you as an employer make the risk assessment of high-voltage vehicles easier and to ensure the safest possible working environment for your employees.

Now let's take a closer look at the different qualification levels – there are three altogether:

  • Level 1: Electrotechnical/expertly instructed person

  • Level 2: Qualified for work in research and development and on non-high-voltage intrinsically safe production vehicles and prototypes

  • Level 3: Qualified for work on live high-voltage components

What the levels mean and what concrete activities you can do with them can best be seen in the following table:

Level 1 Level 2 Level 3
Non-electrotechnical tasks Eletrotechnical tasks on stress-free high-voltage systems Work on live high-voltage components
  • General maintenance and repair work
  • Certified unlocking
  • Repair work on the live high-voltage system
  • Working on the low-voltage vehicle electrical system
  • Repair work on the stress-free high-voltage system
  • Troubleshooting the live high-voltage system
  • Specified work on high-voltage systems
  • Troubleshooting the voltage-free high-voltage system
  • Test drives
  • Removal and installation of (high-voltage) components
  • Certified commissioning

By the way:

Here at ZF were are defining Level 2, a person "qualified for work in research and development and on non-high-voltage intrinsically safe production vehicles and prototypes" as ZF high-voltage expert. The final step would then be ZF high-voltage expert Level 3.

My tip for employers or mechanics – if you intend to maintain, service or provide hybrid, electric or fuel cell vehicles as rental cars, you definitely need training!

A practical example

High voltage vers. oil change

It's no secret that high-voltage vehicles pose electrical hazards. Let's take one of my favourite subjects as an example: changing transmission oil.

At first glance, this has nothing directly to do with the high-voltage system. However, it is in direct proximity to the high-voltage system. For example, the connections for the electric motor in our 8P are located directly next to the oil pan. Also, for other activities such as changing the clutch or working on the chassis, there are special features to consider, so training is necessary… in fact, it is vital.

Because when working with high-voltage vehicles the number one rule is: SAFETY FIRST!
