Rolling Jamming Transmitters The Future Belongs to Electromobility

The future undoubtedly belongs to electromobility. However, the automotive industry as the technology driver par excellence still has a few hurdles to overcome. These include electromagnetic compatibility, which has hardly been a topic so far.

The social and political pressure to reduce CO2 emissions is an ideal catalyst for the successful and rapid spread of electric vehicles. There is no doubt that the number and importance of electric vehicles will one day exceed that of conventional combustion engines. But even they are not exempt from technical problems that still must be solved. The question of the availability and ecologically justifiable degradability of the raw materials for the batteries could be mentioned here or, to the same extent, the inadequate charging infrastructure to date (White Paper EV Charging [1] ).

 

Electromagnetic Compatibility

One topic, which is hardly addressed in the news today, is that of electromagnetic compatibility. Where a current flows, an electromagnetic field is created. And, electricity is omnipresent in electric vehicles. Components for the powertrain, in particular, are sources of unwanted electromagnetic emissions. Possible adverse effects on other electronic systems, possibly safety relevant (both onboard and off-board) - not to mention the vehicle occupants - must be avoided to the extent possible.

 

What's to be done?

There are many ways and means to protect against electromagnetic interference. The layout of the cabling, its shielding, etc., for example, can be very complex. Rather than attempt to list or define what would be an application specific approach, we suggest narrowing the scope to the use of external EMC filters. But what do such filters do? Using passive components (chokes and capacitors), the undesirable interference signals are attenuated many times over in their intensity, so that their damaging effect does not occur.

Automotive = highest demands In contrast to some industrial or medical filters, for example, the requirements in the automotive sector are much tougher. Such a filter must be particularly robust. Robust against vibrations, impacts and shocks; Robust against large temperature fluctuations when leaving the heated garage in the morning in winter. But it must also be light and compact in order to use as little space as possible, while at the same time minimizing added weight to the vehicle.

 

SCHURTER FPAB

Exactly tailored to these needs is the latest filter series FPAB, which - as usual at SCHURTER - can be fully customized. This single-stage filter places a high value on robustness, impermeability to dust and moisture. Thanks to the use of a well-sealed connector from Tyco, which is popular in the automotive industry, it is particularly lightweight and used universally. All connections are screwed to withstand even the most stubborn vibrations.
