harmful electromagnetic radiation

harmful electromagnetic radiation

since tesla car is made of full of electric..will it produce harmful electromagnetic radiation on driver?what is electromagnetic radiation level in tesla cars?

HPWC installation manual warns of possible effect to those with a pacemaker and ICD implanted DEVICEs while CHARGING.

Teslax says to consult your device manufacturer for information.

Tesla says that the actual driving,while being inside, is a non issue

Timo | January 24, 2016

I'm pretty sure that that warning is there just for legal reasons, not because there is any danger whatsoever even when charging.

There is practically no electromagnetic radiation, or at least it is far smaller than ICE causes. There is a small magnetic field though that isn't present in ICE cars.

vperl | January 24, 2016

Well, if you had a Pacemaker, or ICD implanted you may not be so assured.

But, there has to be someone that owns a Tesla that has one of the implanted devices could speak from actual personal experience.

Read the HPWC installation manual as you install the HPWC. LEGAL or not Caution is a good thing.

The motors and electronics are encased in metal housings which are shielded. The one component that could possibly cause some rf and emf would be exposed high power cables that have a frequency running through them.
The FCC requires ALL electronic and electrical devices, and associated connections to meet certain emission requirements, and to not exceed those requirements. They have taken into account pace makers, and anything else that could be affected by stray emissions.
I am sure that Tesla has manufactured their devices to be well within specifications.

I hope your correct, for my own self-interest.

Nice household micowaves used to be a worry, but that seems not to be a he case now...unless your inside the device while heating your pizza.

DC charging has no frequency.

vperl | January 24, 2016

AC does.

jordanrichard | January 25, 2016

Typically when AC charging, your car is in the garage and you are not standing there for 3 hours.

vperl | January 26, 2016

Really, good news..

How's about while in garage, your setting preferences checking charging or just doing something in the X ? For ten minutes?

Timo | January 26, 2016

If you are afraid of AC high power charging then don't use it. I bet that if you measure the electromagnetic field near the charger that could induce something to your pacemaker you find that to be far too small and working on way too low frequencies to actually do something.

vperl | January 26, 2016

Timo, you are a encyclopedia of knowledge. Please test you hypothesis on a family member or youself first.

But, I am sure you and a family member would be just fine.

You, Timo, are my source for knowledge.

Thanks again.

The passenger compartment is isolated from the high power components by metal which is shielded.
Heck, the battery pack is even armor plated, also shielded. It also appears that the high voltage cables also run in their own metal troughs. Since all of that metal is connected, it is also shielded.
About the only emissions I can see getting in or out of the vehicle are the communications signals, and those are intentional. Also, for communications signals to function properly, they absolutely, positively have to be isolated from high voltage emissions.

Good, great to know.

There is nothing new about radiation. Metering devices and standards have been out for a very,very long time. Nothing new, nothing mysterious.

For those worried about "harmful electromagentic radiation", there are free apps for *measuring* static magnetic fields (like the Earth field) or varying electromagnetic fields.

It is good to compare what it means by "electromagnetic radiation" (EM). Visible light, infrared and X-rays are, as the kHz to GHz radio frequencies in a car, all forms of EM, but of such a different frequencies that each kind can be harmful at different intensity levels.
At some level X-rays can kill cells, solar UV can burn skin, infrared can damage the eyes, microwaves heat, etc.
Simply the intensity level of kHz to GHz EM in a car is very low because of metallic shielding. If you don't believe it, measure it! Then compare with what you would find next to a big power line, or a TV or cell phone broadcasting station, or just a cell phone next to your head. You might find that the EM level in a car is a tiny fraction of these examples.

Timo | January 27, 2016

Radiation and fields are two different things too. IIRC Fields lose power at cube of the distance while radiation loses power at the square of the distance. Fields contain energy. That energy does not go anywhere unless there is something to absorb it (and turn it to another kind of energy).

Radiation is energy of various forms and the emitter loses energy regardless of if that radiation hits anything.

Roughly speaking. Maths involved are not quite basic elementary school stuff. Maxwell's equations and the like.

Why should you worry?

Got skin in this topic?

So as a person once told me, "go fish in some other pond".

Gery | April 25, 2019

I have skin in this game as I own a Roadster. I also have a plant with sewing machines. We know that unless shielded with a Faraday cage (chicken wire grounded), the operators are prone to bowel cancer. The Roadster AC induction motor I believe is the same kind, just bigger. I have a tester for RF but not for the type of radiation commonly emitted by these motors. So, I will have a consultant test and report back. But, surely Tesla has done this already and can provide the data.
Has Tesla shielded and grounded the car engines? If not, we have a problem Houston. Gery Warner, P.Eng.

Ummm, bowel cancer related to 60 hertz electromagnetic fields from sewing machines? No, just no. You have left the path of wisdom my son. | April 26, 2019

@Gery - Tesla motors are totally encased in conductive metal. As Frank points out, no way are sewing machines causing cancer - far more likely there are other environmental factors - such as breathing fabric dust or other industrial contaminants.

Electric motors do not generate RF electromagnetic radiation. There seems to be a consensus that a magnetic field alone does do any work. The electrical current induces the magnetic field, and i dont think this scenario produces electromagnetic radiation. Anyone else have an input?

andy.connor.e | April 26, 2019

doesnt** do any work

rxlawdude | April 26, 2019

The position of sewing workers (sitting, frequent bending, etc.) is probably more in play than EMF.
