Currents must be measured at many points in the HV electrical system of modern electric vehicles: Be it to analyze charging and consumption processes or to verify protective measures against shield currents. The precise investigation of high-frequency current components requires a wide bandwidth in measurement, and instrumentation in particular can present users with challenges.

• Which currents must be measured at which points in the HV electrical system?
• What requirements are placed on the measurement technology?
• With which methods can currents be measured?
• How can current measurements be performed on test benches and in vehicle testing?

DC and AC voltages in the HV environment are characterized by peaks and dips as well as superpositions and have a significant influence on the interaction of all components. To ensure proper operation of the entire system, regulations set limits and must be verified.

• What are the typical characteristics and interactions of HV voltages in the vehicle electrical system?
• What must be considered when using measurement technology for voltage measurement?
• With which measuring instruments can HV voltages be reliably acquired?
• How can voltage measurements be performed in road tests and on the test bench?

Technological development in the field of on-board charger (OBCs) is currently experiencing a push toward higher integration along with other power electronics of electric vehicles. On-board charger in vehicles have to cope with different grid standards and charging networks worldwide. AC charging verification and OBC testing is therefore a particularly critical step for vehicle series release. The correlation and synchronization of measurement technology integrated in the vehicle with measurements outside the vehicle is also becoming increasingly important.

In this web seminar you will learn:

• How are on-board charger tested and AC charging processes verified?
• How are mobile measurements are performed?
• What power and efficiency analyses are important?
• How CSM supports this development with the new HV BM 3.1 OBC Breakout Module and an customized, airline-grade measurement case for measurements between charging station and electric vehicle.
