As a result of the power train electrification in electric and hybrid vehicles the electromagnetic compatibility of these vehicles is comprehensively affected. Especially the power electronic components operated at battery voltages of around 400V produce broadband EMI inside the vehicle. To prove compliance with the normative requirements considering the vehicles inner EMC, EMI measurements on component...
For a long term success of electric mobility, it's definitely necessary to provide safe charging infrastructures in addition to marketable vehicles. Since safety and functionality requirements on every electric mobility product are extremely high, the interoperability between charging infrastructure and vehicle, as well as the interaction of both systems under every possible environmental condition...
The shielding concept of an electric vehicle's drivetrain has matured over the recent past. But still, there are some issues that have to be solved. One part of the shielding concept are large multi-pole High Voltage (HV) connectors with low DC resistance. Their shape and the fact that they are built up from various components are a challenge when it comes to optimizations regarding the shielding...
In order to understand and design better shielding effectiveness (SE) of HV cables and connectors for electric vehicles (EV), appropriate measurement methods are required. The Transfer Impedance ZT is usually measured using Triaxial or Line Injection method. Based on a simplification of Triaxial method, a Ground Plate measurement method has been proposed to evaluate SE of cables and the cable-connector...
