Electric cars and electromagnetic fields


Theelectric carscan they be dangerous for the driver's health? Already in the article entitledElectric cars and Peacemakerwe talked about electromagnetic fields, today we return to the subject to definitively exonerate all types of electric vehicles.

The doctors at the Mayo Clinic of Arizona had already reassured us, imagnetic fieldsproduced byelectric carsI'm not "clinically relevant“, So any passenger or driver with prostheses or peacemakers can travel safely aboard oneelectric car. Research from the Mayo Clinic wasn't enough and even today, many people worry aboutmagnetic fields generated by electric cars.

Why do electric cars produce magnetic fields?
They can form in the cockpit of any car electromagnetic fields (EMC)relatively intense low frequency. In an electric car i electromagnetic fields are mainly generated by magnetized steel elements inserted in the tires and by all the electrical components: from the engine to the ignition products, from the dynamo, from the air conditioning system ... The highest values ​​are recorded near the floor of the cars, where the battery pack is located and at the time of ignition.

To address the topic "electric cars eelectromagnetic fields"We report another important research that analyzed, with extreme detail, the quantity ofmagnetic fieldsproduced by the EVs.

Electric cars eelectromagnetic fields, the analysis conducted by Tell
The study, conducted by Tell and collaborators and published in the international journalBioelectromagnetics, in an article entitled "ELF Magnetic Fields in Electric and Gasoline-Powered Vehicles", assessed and compared the levels oflow frequency magnetic fields (range between 40 Hz -1 kHz) emitted in electric vehicles and in those fueled by petrol, so as to check whether the measured parameters are below the legal limits reported in the ICNIRP (International Commission on Non-Ionizing Radiation Guidelines) Protection).

In all, 14 vehicles were analyzed: 6 petrol, 5 electric cars and 3 hybrid cars. The magnetic field levels present in the passenger compartment of the car were determined using six broadband meters capable of sampling every 4 seconds and the results were treated through statistical correlation tests.

The research has found that, it is true, in electric cars there are almost double the magnetic fields present in petrol cars, but these are always values ​​below the legal limits. Specifically, the average magnetic field measured on electric cars was of the order of 0.095 mT against an average level of 0.051 mT detected on petrol cars, much higher values ​​were measured on trucks (0.146 mT for electrically powered ones 0.081 mT for those with petrol). In any case, these are values ​​that remain well below the reference levels for public exposure indicated by the ICNIRP for the specific frequency range.
