EMF (Eletromagnetic field) in Tesla Model S

    Hello all,

    Some concerns have been raised about possible effect of the electromagnetic field in EV (or hybrid).
    I'm driving a Model S since one week (what a fantastic car, probably the best !) and together with a colleague, we did some tests.

    Our questions were:

    1- what is the maximum value of the Electromagnetic field (EMF) when the car is parked?
    2- what is the maximum value of the Electromagnetic field (EMF) when we press the pedal?
    3- is there a big difference with conventional car?

    Here is the situation:

    - A Tesla Model S (2014), 85 KW, Tech Package, Pano, Black Leather,Sunroof.
    - Location: indoor parking.
    - Measurement devices: Gigahertz-solutions NFA1000 + Gigahertz-solutions NF59B+ filter FF6

    Test findings:

    To conduct our tests, we used a EMF meter from Gigahertz Solutions.

    1nT = 1 x 10-9 T

    1- Maximum value when the car is ON and parked: 20 nT
    2- Maximum value during acceleration: 800 nT
    3- Difference with conventional car: I found some test findings on the internet.

    Examples: 2008 Mini Cooper Clubman: 300 nT
    2008 Chevrolet Cobalt: 3000 nT
    In the most terrible: BMW 5 : 7000 nT

    Conclusion: The test is very basic and I'm sure I can do much more on this.
    We can imagine several other scenarii and put this in a technical report.
    At this first stage, I found no evidence that Tesla Model S exposes the people inside to significantly more EMF than do conventional car.
    In some case, it's the opposite. The Model S is very well shielded (for many reasons).

    By the way, pleae note that like most modern cars, WiFi, Bluetooth and 3G are very active...but it's a different subject.

    Thanks to Tesla engineers !

    Just searching on titles only in Model S (plenty in the Roadster forum): EMF Radiation

    There is also plenty of discussion in various threads.

    Good to see some definitive measures against existing ICE vehicles. I'll bookmark this thread and use it when the question comes up (and it always comes up again) in the main forum.
