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?
