ISO 21782-4 Electrically Powered Road Vehicles - Performance Testing of DC/DC Converter

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 21782-4 testing. This standard specifies the performance tests and each rating for the DC/DC converter in the voltage class B electric propulsion system of electrically powered road vehicles.

The purpose of this test is to measure the loss and efficiency of the DC/DC converter to operate the DC/DC converter under specified conditions and ensure performance is as designed.

The DC/DC converter is a critical component in electric drive systems, responsible for converting the high voltage DC power from the battery to the low voltage DC power required by various vehicle systems such as lighting, audio and climate control. Performance testing of the DC/DC converter is necessary to ensure that it operates efficiently and reliably and meets the required standards.

ISO 21782-4 defines various terms and concepts related to performance testing of DC/DC converter, such as:

• DC/DC converter efficiency: the ratio of the output power to the input power of the DC/DC converter;
• Input voltage range: The DC voltage range that the DC/DC converter can accept as input;
• Output voltage range: DC voltage range that the DC/DC converter can output;
• Output current range: The DC current range that the DC/DC converter can output.

ISO 21782-4 provides guidance on performance testing of a DC/DC converter, including:

• Measurement of DC/DC converter parameters: the standard specifies methods and equipment for measuring parameters such as DC/DC converter efficiency, input voltage range, output voltage range and output current range;
• Test conditions: the standard specifies the environmental and electrical test conditions that must be maintained during the testing process;
• Test procedures: the standard outlines the test procedures to be followed, including setting up test equipment, measuring required parameters, and recording results;
• Acceptance criteria: the standard specifies acceptable performance levels for DC/DC converter components based on measured parameters.

ISO 21782-4 provides a standardized approach to performance testing of DC/DC converter, which helps ensure it meets required performance standards and operates safely and reliably in electrically powered road vehicles.
