ISO 21782-1 Electrically Powered Road Vehicles - Test Specifications for Electrical Propulsion Components

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 21782-1 testing. This standard specifies test procedures for performance and operating load for voltage class B electric propulsion components (motor, inverter, DC/DC converter) and their combinations (motor system) of electrically powered road vehicles.

Until now, there was no internationally standardized test procedure for the motor system for electric propulsion systems of electrically powered road vehicles, including motors, inverters, DC/DC converters and combinations thereof. There are some International Standards for industrial use that take into account stable/steady operation of motors and inverters but not dynamic operation (acceleration/deceleration).

The ISO 21782 series has been prepared with the aim of repeatability of test results that will enable fair comparison and evaluation of the performance and reliability of electrical drive system components such as the motor system (motor, inverter, DC/DC converter and combinations thereof).

ISO 21782-1 is a standard that specifies general test conditions and definitions for electric drive components used in electrically powered road vehicles. The purpose of this standard is to provide a framework for testing electrical drive components to ensure their reliability and safety.

The standard defines various terms and concepts related to electrical drive components and their testing, such as:

• Electric propulsion system: A system that includes one or more electric motors, power electronics, and energy storage systems used to propel a road vehicle;
• Test item: a component or system under test;
• Test plan: A document specifying the tests to be performed, the test conditions, and the acceptance criteria for each test;
• Test report: A document that provides the results of the tests performed and the conclusions drawn from these results.

The standard also provides guidance on the selection of test conditions and performance of tests for electrical drive components, including:

• Environmental conditions: the standard specifies test conditions for temperature, humidity, altitude and vibration;
• Electrical conditions: the standard specifies test conditions for voltage, current, and frequency;
• Mechanical conditions: standard specifies test conditions for mechanical loads, shock and impact;
• Electromagnetic compatibility (EMC): the standard specifies test conditions for EMC, including radiated emissions, conducted emissions, and sensitivity.

ISO 21782-1 is part of a set of standards covering the testing of electric drive components for electrically powered road vehicles. Other parts of the series cover certain electrical drive components such as electric motors, power electronics and energy storage systems.
