Overview

ISO 21782-1:2023 - Electrically propelled road vehicles - Test specification for electric propulsion components - Part 1 defines the general test conditions and definitions used across the ISO 21782 series. It specifies standardized test procedures and terminology for voltage class B electric propulsion components: motor, inverter, DC/DC converter, and their combinations (the motor system). The standard enables reproducible, comparable performance and operating-load testing for electrically propelled road vehicles.

Key topics and technical requirements

Scope & terminology: clear definitions for components and test-relevant terms (e.g., chopper, DC/DC converter, conversion rate, efficiency, maximum current/power/torque for specified durations).

General test conditions:

Operating points for motor, inverter and motor system (defined in figures and tables). Test durations t include 2 s, 10 s, 1 800 s (30 s or 60 s optional).
Methods for determining rank during operating-load tests: target rank verification and rank search methods.
Provision for measurement: requirements for current, voltage and power measurement and measurement accuracy.
DC input voltage ranges and considerations (aligned with voltage class B definitions and OS1 references).
Environmental conditions: temperature and humidity control and steady-state (room temperature) starting conditions.

Abbreviations & references: standardized shorthand (AC, DC, PWM, RT, DUT) and links to ISO/IEC terminology resources.

Informative annexes: example formulas for power calculation and a bibliography supporting the series.

Practical applications

Standardized lab test protocols for component performance characterization (efficiency, loss, torque/speed behavior).

Operating-load and endurance testing to assess durability and thermal limits (e.g., maximum current/power for defined durations).

Component and system validation during R&D, prototype evaluation, and pre-qualification for production.

Supplier comparison and procurement specification: enabling fair, reproducible comparisons of motor systems and converters.

Test-bench and regulatory test program development for electric vehicle (EV) propulsion components.
