Reliability of power electronics/modules in electric cars
A further aspect is the development of methods to analyze suspected reliability issues of high power electronics and modules applied in electric vehicles. It offers novel approaches to detect cracks, delamination and overheat situations by computer simulation in advance and as a part of the design procedure of such systems. The methods include the combination of different detrimental effects as like as thermo-mechanical stress and fast change of stress conditions, the combination of load power, temperature change and external mechanical load and vibrations and the experimental evaluation and practical analysis.
