Power-Level Testing of Electric Vehicle Components such as High-Voltage Controllers and Inverters
Electromobility is picking up speed, particularly in urban and metropolitan areas. Electric city buses provide the low-emission mobility required in these areas. A high availability of buses is indispensable for public transport. Therefore, new drive systems have to be tested particularly thoroughly.
The company Avantest from Alsdorf in North Rhine-Westphalia provides services for the validation of power electronics and electric systems. For this purpose, their test lab is equipped with an electronic high-voltage test system from dSPACE. The system can emulate the motors and battery of a bus at power level, making it possible to test the electronic control units, including the power.
What does CTO Andreas Cleven think about it?
The electronic high-voltage test system from dSPACE enables us to precisely emulate an electric motor and a battery at power level. This lets us perform reliable tests of power control units under real electrical conditions.
