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 !
