Your trainer. Your expert. Jan-Hinrick Behrens.
I am an HV trainer and expert in electromobility, currently based in Berlin, combining engineering knowledge, hands-on experience, and a genuine passion for safe high-voltage qualification.
For more than ten years I have worked in electromobility, vehicle technology, and safety-critical HV systems. My focus is on practice-oriented training, DGUV-compliant instruction, and the technical analysis of electric drive and storage systems. This is built on my engineering expertise, my teaching experience, and my practical background in the automotive sector.
This drives my commitment: to make complex technical relationships understandable and to convey lasting understanding rather than mere regulations. That is why I support companies and technicians from the very first step through to complete HV qualification: individually, practically, and in full compliance with standards.
Why I do this with passion: because understanding protects lives.

My modular concept makes it possible to minimize training costs while maximizing safety. Each employee receives from me exactly the qualification their role requires – no more, no less.
Understand. Apply. Act Safely.
At the heart of my teaching approach is not regulation, but understanding. I am convinced that those who truly grasp technical relationships act safely – not because they have to, but because they can.
Understand
I make complex high-voltage concepts tangible and comprehensible through modern visualizations, technical animations, and engineering-based explanatory models.
Apply
Practical exercises on real vehicles and high-voltage systems are the focus of my training – creating genuine operational confidence that goes beyond theoretical knowledge.

DGUV 209-093 & UNECE R100 – Regulations I Work By
DGUV Information 209-093
"Qualification for Work on Vehicles with High-Voltage Systems"
Edition August 2021 · Previous number: DGUV 200-005
Published by the German Social Accident Insurance (DGUV) in cooperation with the ZDK (German Motor Trades Association), this information defines the requirements for qualifying persons who carry out work on vehicles with HV systems.
It applies to land vehicles (passenger cars, trucks, buses, industrial trucks, two-wheelers, among others) – but not to rail-guided vehicles, watercraft or aircraft, or vehicles permanently connected to a power grid.
DGUV Information distinguishes between two level systems:
- S, 1S, 2S, 3S – for work on series-production vehicles
- E, 1E, 2E, 3E – for development & production
The FHV (Certified High-Voltage Person) is recognized as an electrically skilled person under DGUV Regulations 3 and 4 for the high-voltage systems specialty. In all my training, I ensure full compliance with these requirements – from basic instruction through to full qualification as a skilled professional.
UNECE R100 – Regulation No. 100
"Uniform Provisions Concerning the Approval of Vehicles with Regard to Specific Requirements for the Electric Power Train"
UNECE R100 is an international regulation of the United Nations Economic Commission for Europe and defines the safety requirements for electrically powered vehicles and their high-voltage components.
It defines high voltage as:
- > 60 V and ≤ 1,500 V direct current (DC)
- > 30 V and ≤ 1,000 V alternating current (AC)
UNECE R100 sets out protective measures, insulation requirements and test procedures for HV systems and is referenced in DGUV 209-093 as international regulation.
I teach UNECE R100 not as an abstract regulation, but as a practically applicable safety tool – clear, hands-on and fully integrated into my training.
Frequently Asked Questions.
What prerequisites apply to the high-voltage qualifications?
The prerequisites vary depending on the qualification level. Level 1 requires no specific prior knowledge. From Level 2 onwards, relevant prior knowledge or a completed Level 1 qualification is required. A detailed overview can be found in the respective training descriptions or is available on request.
Are the trainings manufacturer-specific?
No. All of my trainings are designed to be fully manufacturer-neutral. The competencies imparted apply to all common vehicle brands and high-voltage system architectures.
How long are the qualification certificates valid?
DGUV Information 209-093 recommends regular refreshers of the qualification. I am happy to advise you on the recommended renewal intervals for your specific industry and activity.
Are in-house trainings possible at our site?
Yes. In-house trainings are available for all training formats and levels. I come to you, qualify your employees on your vehicles, and adapt the training concept to your processes.
Can trainings be developed for specific vehicles or systems?
Yes. As part of project-based corporate trainings, I develop fully individual qualification programs tailored to your specific vehicles, production facilities, or service processes.
More Frequently Asked Questions.
What does a high-voltage training cost?
Costs vary depending on the training format, number of participants, and location. Modular group offerings are generally considerably more cost-effective than individual sessions. I am happy to prepare an individual quote for you.
Which standards form the basis of the training?
My training courses are based on DGUV Information 209-093, UNECE R100, relevant VDE guidelines, and industry-specific requirements. All content is continuously updated to reflect the latest state of the standards.
How many participants can take part in a training session?
My training sessions are designed for group sizes of 4 to 16 participants. For larger corporate groups, I develop multi-stage training programs. In-house training sessions start at 6 people.
Do participants receive an official qualification certificate?
Yes. All training completions are documented with a qualification certificate that meets the requirements of DGUV Information 209-093 and is recognized by authorities, insurers, and testing organizations.
