ISO 21782 is a series of international standards on electrically propelled road vehicles that discusses operating load testing of motor and inverter.
ISO 21782‑6 is the sixth part of the ISO 21782 series of documents that specifies operating load tests and test criteria for motor and inverter designed as a voltage class B electric propulsion system for electrically propelled road vehicles.
ISO 21782‑6 on electric road vehicles is useful for:
An electrically propelled road vehicle is one that operates on an electric motor, instead of an internal-combustion engine that generates power by burning a mix of fuel and gases.
ISO 21782‑6 navigates you through the requirements for the operation endurance tests of the motor to evaluate and rank the strength for the components – bearing, end ring, motor shaft key, rotor fixture, rotor, and position sensor.
ISO 21782‑6 specifies the conditions for the high acceleration/deceleration endurance test of the motor.
ISO 21782‑6 provides guidance regarding the requirements for the operation endurance test of an inverter including test objectives and time aims to prevent failures in main power conversion parts. Breakdown strength verification test of the motor is given in ISO 21782‑6 that aims to know the mechanical strength of the motor.
Overall, ISO 21782‑6 assist you in manufacturing voltage class B electric propulsion components with the load testing to generate sufficient power to run the vehicle which will enable you to compare and evaluate the performance and reliability of motor, inverter, DC/DC converter and their combinations (motor system). With obedience and compliance to ISO 21782-6, you can achieve precision in terms of product functionality.
