The components of electric vehicles are being further developed and optimized. For this, multi-channel, electrical power measurement is necessary. It is the basis for the comprehensive analysis of the efficiency of inverters, electric motors, converters or charging systems.

In this episode of CSM Xplained, learn how this is easily done with the Vector CSM E-Mobility Measurement System.

• Overview of the basics of electrical power measurement
• How is electrical power calculated with the eMobilityAnalyzer?
• How can power analysis be easily performed on the electric motor?
• How is the power and efficiency measurement performed on the powertrain?
• How are power losses and efficiency determined at the inverter or charging system?

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.

Mobile machines must comply with increasingly stringent emission limits, which inevitably means that working functions, the traction drive or even the complete machine are moving toward electrification. This poses completely new challenges for the testing of mobile machines, as high-voltage electrical variables must now also be measured and recorded in field tests.

In this webinar, we address these challenges and answer the following questions:

• How are the components of mobile machines changing as a result of their electrification?
• What do these changes mean for testing and field trials?
• How can mechanical and high-voltage electrical measured variables as well as fieldbus data be acquired and analyzed synchronously and, above all, in a user-safe manner?
