ISO 21782-6 Electrically Powered Road Vehicles - Working Load Test of Motor and Inverter

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 21782-6 testing. This standard specifies operating load tests and test criteria for motor and inverter designed as a voltage class B electric propulsion system for electrically powered road vehicles.

ISO 21782-6 is part of a set of standards that specifies test specifications for electric drive components used in electrically powered road vehicles. Chapter 6 of this series, ISO 21782-6, provides guidelines for operating load testing of motor and inverter used in electric drive systems.

Working load testing of the motor and inverter is essential to ensure that they can operate reliably and safely in real-world driving conditions. The test involves subjecting the motor and inverter to various load conditions that mimic real driving conditions of the vehicle.

ISO 21782-6 defines various terms and concepts related to working load testing of motor and inverter, for example:

• Duty cycle: ratio of operating time to the total duration of the test cycle;
• Load profile: a set of load states representing typical driving conditions of the vehicle;
• Acceleration and deceleration profiles: time-varying profiles of vehicle acceleration and deceleration during testing;
• Test points: specific operating points within the load profile where the performance of the motor and inverter is measured.

ISO 21782-6 provides guidance on operating load testing of motor and inverter, including:

• Load profile development: the standard specifies load profile development methods including acceleration and deceleration profiles and selection of test points;
• Test conditions: the standard specifies the environmental and electrical test conditions that must be maintained during the testing process;
• Test procedures: the standard outlines test procedures to be followed, including setting up test equipment, applying a load profile, measuring required parameters, and recording results;
• Acceptance criteria: the standard specifies acceptable performance levels for motor and inverter components based on measured parameters.

ISO 21782-6 provides a standardized approach to operating load testing of motor and inverter that helps ensure that electrically powered road vehicles can operate reliably and safely in real-world driving conditions.
