IPTE has developed and brought to market a universal semi-automatic test application for the so-called power modules in the charging units of electrical vehicles (EVs). The requirement was to test the assemblies which control and switch high voltages and currents in a manner that was safe, precise and could be 100 % reproduced and documented.
The charging units handle an output of 10 kilowatts and the assembly is tested without housing and shielding. This requires appropriate shielding measures as the test piece generates high-frequency interference and electromagnetic fields that can influence the measuring devices. In addition, the weight, 20 kilogrammes, requires a stable base and contact device.
