Measuring Shield Current of High-Voltage Cables in Electric Vehicles

The high-voltage cables of the high-voltage vehicle electrical systems in modern electric vehicles are exposed to strong current and voltage ripples, which induce currents in the braided shields. If these shield currents exceed the capacity of the braided shield, cable fires and damage to connected accessories are the result. To ensure the safety of the system, extensive measurements of the shield currents are necessary.

Overview: Verification of High-Voltage Electrical Systems

Verification of High-Voltage Electrical Systems

The high-voltage electrical system in electric and hybrid vehicles is validated at all stages of development and extensively tested for series production release. CSM HV Breakout Modules are particularly suitable for these validation and acceptance measurements in accordance with the ISO 21498-1 and -2 standard because they can be used directly in the HV cables of the vehicle electrical system.

Application Example Fuel cell-electric drive functional test

Fuel Cell-electric Drive Functional Test

Fuel cell-powered vehicles are a complement to pure battery electric-powered vehicles in electromobility. An electrochemical reactor is used to generate electrical energy that is available for the drive and other vehicle systems. The interaction of this reactor in the fuel cell stack with the other components in the powertrain is tested on test benches. In this example, you will learn how the necessary measurements are carried out simply and synchronously.
