Electric Hybrids and Risk Prevention PES – PAV – PEI

A hybrid or hybrid propulsion vehicle is a vehicle equipped with a propulsion system consisting of two or more components, such as an electric motor with a thermal engine.

Technical interventions on a hybrid engine require specific expertise and adequate qualification to carry out electrical work on electric vehicles.

The ability to perform electrical work is obtained through a training process that includes not only the development of theoretical knowledge but also the acquisition of practical skills.

Obtaining qualifications for personnel performing electrical work on electric or hybrid vehicles can be as a ‘Persona Esperta’ (Expert Person – PES), ‘Persona Avvertita’ (Informed Person – PAV), or ‘Idonea ai lavori sotto tensione’ (Suitable for Live Work – PEI)

PAV – Persona Avvertita (Informed Person): A person adequately informed by expert individuals to enable them to avoid the dangers that electricity can create.

PES – Persona Esperta (Expert Person): A person with relevant education, knowledge, and experience that allows them to analyze risks and avoid the dangers that electricity can create.

PEI – Persona Idonea (Suitable Person): A person recognized with the technical capacity to perform specific live work.

Lupo Autoricambi, in collaboration with Magneti Marelli, is ORGANIZING a professional technical course for PES-PAV-PEI lasting 16 hours. Participation in the course on ELECTRIC HYBRIDS – PES PAV PEI requires a basic knowledge of the principles of electronics/electrotechnics applied to automobiles.

The course will be spread over two days and will enable participants (subject to passing a final test) to receive a certification that qualifies them for safety and maintenance interventions on hybrid and electric propulsion vehicles.


Day 1
