The development of electrically driven vehicles requires optimization of both the power electronics and the ECU application. In most cases, they influence each other. Merely measuring voltages and currents is not sufficient as a measure for optimizing the power electronics. Only derived values such as active power and efficiency are meaningful.

With CSM measurement technology and Vector measurement software with integrated eMobilityAnalyzer function library, ECU internal values can be measured and adjusted while analog measurement signals can be synchronously acquired and analyzed. Based on real measurement data, we present our joint solution.
