BS ISO 21782-4:2021

What is ISO 21782‑4 about ?  

ISO 21782‑4 is part four of the multi-series standard on test specification for electric propulsion components, performance testing of the DC/DC converter. 

ISO 21782‑4 specifies performance tests and each evaluation for the DC/DC converter in the voltage class B electric propulsion system of electrically propelled road vehicles. 

Who is ISO 21782‑4 for ? 

ISO 21782‑4 on test specification for electric propulsion components-performance testing of the DC/DC converter is applicable to: 

• DC/DC converter manufacturers 
• Electric vehicle manufacturers 
• Electric vehicle charger manufacturers 
• Electric vehicle battery manufacturers  

Why should you use ISO 21782‑4 ?  

ISO 21782‑4 gives test to operate the DC/DC converter under the specified conditions and to measure the loss and the efficiency of the DC/DC converter in order to ensure the performance is as designed. The test will help you improve the performance of the electric vehicle. 

ISO 21782‑4 provides test to operate the DC/DC converter under the specified conditions and to measure the temperature rise in the DC/DC converter in order to ensure the thermal performance is as designed.
