Why technical competence and safety competence require different educational pathways If technical EV competence and HV electrical-safety competence serve different purposes, the next question follows naturally: Do both competencies need to be developed through the same educational pathway? Not necessarily. Separating EV and HV provides an opportunity to use existing education and training structures [...]

What does a person working on an electric vehicle need to know? The common answer is often: “They need high-voltage training.” But that does not tell us enough. Understanding battery technology is different from diagnosing power electronics. Diagnosing power electronics is different from establishing a de-energised state. And establishing a de-energised state is different [...]

An electric vehicle is a technical system. Voltage is a physical quantity. An electrical hazard describes the potential for electrical energy to harm a person. Yet all three concepts are frequently combined under a single term: High Voltage. The distinction becomes increasingly important as electric propulsion expands beyond conventional road vehicles. The relevant question [...]

Why a new definition is becoming necessary “High voltage” has become an established term in electric mobility. It is used to classify electrical systems, define safety concepts and increasingly to describe training and qualifications. But this creates a problem: Today, HV may describe a voltage class, a vehicle system, a hazard and a qualification [...]
