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 should therefore no longer simply be:

Is this a high-voltage vehicle?

It should be:

What electrical hazard exists during this specific task?

A driver, a mechanic replacing a tyre, a technician establishing a de-energised state and a specialist opening an energised battery system face completely different conditions.

They therefore require different competencies.

Vehicle standards such as ISO 6469-3 legitimately classify electrical circuits for vehicle-safety purposes.

A competence system, however, needs to answer a different question:

What does the person need to know and be able to do?

This leads to a simple distinction:

EV → the technical system

HV → the electrical hazard

Or, in its shortest form:

EV ≠ HV

An electric vehicle is not a hazard.

It is a technical system in which electrical hazards may arise depending on its design, condition and the work being performed.

In the next article: If EV and HV are not the same, this has direct consequences for qualification. Why technical vehicle competence and electrical safety competence should be considered separately.
