As hybrid and electric vehicles become more prevalent, almost all auto repair shops will need to handle them sooner or later. Working with high voltage (HV) systems in these vehicles requires awareness of potential dangers and protective measures. This applies to all employees, including mechanics, cleaning staff, and office workers who might come into contact with the vehicles.
With e-mobility dominating the auto industry, training on HV systems is increasingly necessary. Building on your foundational knowledge as a vehicle electrician or mechanic, our High Voltage Level 2 training will qualify you to work independently and safely on vehicles with HV systems, including both electric and hybrid vehicles. You will learn to assess delegated work, recognize potential dangers, and implement necessary protective measures. Expand your skills and position yourself for the future market.
Our recently updated training course prepares workers to diagnose and work safely around electrical hazards in the manufacturing, maintenance, or repair of electric vehicle equipment in a non-energized state. The training includes a practical module to ensure you can de-energize electric vehicles and perform non-energized HV diagnostics and assessments, including the proper use of PPE, measuring equipment, and application of electrical safety practices.
Join us in this training to advance your skills and ensure you are well-prepared to handle high-voltage systems in electric vehicles. Enroll today and take the next step in your professional development!

This instructor-led training course qualifies students to work with high voltage (HV) systems in motor vehicles. It is the second level of TÜV SÜD Academy’s three-tiered learning path on HV safety in automotive systems.
HV Learning Pathway
TÜV SÜD Academy’s HV Safety Learning Pathway includes:
- Level 1: Fundamentals of High Voltage Systems in Electric Vehicles (digital self-paced overview course)
- Level 2: Qualified Safety Work for High Voltage Vehicle System in a De-energized State (instructor-led training covering fundamentals of electrical engineering and HV systems)
- Level 3: Live Working EV Training: High-Voltage Vehicle Systems and Battery Safety (advanced training for working with operational high-voltage systems)
These three courses are designed to help keep every member of your organization safe, regardless of physical involvement with new technology.
The HV Level 1 training is a self-paced overview course that participants are required to complete before joining level 2.
The Level 2 is an instructor-led training course that exposes students to the fundamentals of electrical engineering and as well as an overview of HV systems in vehicles. Students who successfully complete Level 2 become qualified to take the Level 3 course to work with operational high voltage systems. Students who do not pass level 2 are not permitted to attend the Level 3 course.
Participants in this training course will:
- Recognize Electrical Components: Understand their proper operation and purposes on a schematic level.
- Troubleshoot and Perform Electrical Work: Safely perform tasks in a non-energized state on HV components.
- Expand Your Knowledge: Gain a deeper understanding of electric mobility.
- Handle High Voltage Vehicles: Reliably manage the demands of working with HV vehicles.
- Perform Electrical Tasks: De-energize electric vehicles, take electrical measurements, and apply PPE and electrical safety practices properly.
- Earn a Certificate: Receive certification from TÜV SÜD Academy as Qualified Safety Work for High Voltage Vehicle System in a De-energized State - Level 2.

The training includes both a theoretical and practical evaluation component.
Participants must complete a proctored final exam, which leads to a Certificate by Exam. This certificate represents Part 1 of 2 of the HV training pathway and is only valid when combined with the Certificate of Practical Training (Module 5).
In addition, the course includes a performance assessment in a practical application, which leads to a Certificate of Attendance. This certificate represents Part 2 of 2 of the HV Training Pathway Level 2 and is only valid in conjunction with the Certificate of Theoretical Training (Modules 3 and 4).
Final Exam – General Information
- Duration: 90 minutes
- Format: Single-choice exam
- Total questions: 20
- Maximum score: 20 points
- Passing requirement: Minimum 14 correct answers
Completion of HV Level 1 Certification or equivalent.
This course is designed for students who have successfully completed vocational training as vehicle mechanics or electrations. This foundational knowledge of mechanical engineering is required.
An equivalent qualification would be any prior training, certification, or demonstrable experience that covers the same core competencies as HV Level 1, such as:
- Basic electrical safety knowledge (e.g., understanding voltage, current, and hazards)
- Awareness of HV risks in EVs/hybrid vehicles
- Knowledge of safety procedures, including:
- Identifying HV components
- Understanding hazard zones
- Basic lock-out/tag-out or isolation concepts
- Familiarity with PPE requirements for electrical environments
- General training in working safely around HV systems (not necessarily working on them)
Examples of acceptable “equivalent” background
- A similar HV Level 1 training from another provider
- OEM (manufacturer) introductory HV safety training
- Electrical safety certification with EV/HV content
- Relevant technical education or apprenticeship (e.g., electrician, automotive technician) that includes HV safety basics
- Documented work experience with EVs/hybrid vehicles under supervision
What it does NOT mean
“Equivalent” does not include:
- No prior exposure to HV systems
- Only general automotive experience without HV safety training
- Informal or undocumented experience
