Electromagnetic fields from Tesla

Electromagnetic fields from Tesla

Anyone experience side effects from the electromagnetic fields produced by Tesla batteries as a driver or passenger?
Such effects may include but not limited to nervousness, tingling in arms or legs, anxiety, a feeling of unusual fatigue, increased heart rate...?

Batteries are DC power and dont generate an oscillating magnetic field.

There have been many threads on this psychosomatic issue.

I'm usually fine, as long as I remember to wear my tinfoil hat...

What ever the above posts say, what they speak about this subject is false.

Pacemakers and Implantable Cardiac defibrillators are in fact dangerous to these individuals while charging. One cannot be in inside vehicle while charging if you have one of the implants.

You can drive the vehicle, but you put yourself in great danger if you are in the vehicle while charging.

Those that disagree need to contact the device manufacturer.

I am sure some idiot will proclaim this is false.

I doubt they have these implants.

I await proof contrary from either Tesla or Medtronics, that charging and sitting in vehicle is safe for a person with either implant.

You can't prove a negative. So where is your proof that this is a problem?

Dramsey | 17 January 2015

"You can drive the vehicle, but you put yourself in great danger if you are in the vehicle while charging."

You specifically said, in another thread, that you had no information from either Tesla or the medical device manufacturers about this issue. So why are you certain that there is a problem? I mean, you do seem very, very, certain…

vperl | 17 January 2015

Do you have implanted device?
I cannot let some one pass a metal detector wand across me or I cannot go through metal detectors at airports or other places .

There was by Medtronics a warning, but I do not know for sure , for absolute fact the massive charging of battery hole sitting at inside is safe. Never got definitive answer.

Please get implant and test for me. I have a buddy that sells caskets at discount. Just in case.

vperl | 17 January 2015

Repeat, you guys have nothing at risk.

So, unless you have definitive information from Medtronics and Tesla you need to go away.

vperl | 17 January 2015

So, you are a expert on this subject and an engineer for Tesla on this topic or for device manufacturers, like Medtronics.

You are not in danger, I have been verbally told sitting in vehicle while charging is dangerous. Tesla & device companies seem not to be put on record in writing. Either no problem or problem, need actual proof, not some hair brained poster with nothing to loose.

Charging (slowly) in home is equally dangerous to walking next to electric oven while something is cooking.

Charging at SC is DC which doesn't cause any problem with any implanted device, because there is no induction happening. It's a lot safer than walking next to person that had accumulated some static charge from synthetic clothing.

There should be no danger from charging.

If that's Medtronics saying you that "you are in danger" I'm pretty sure that it's their ignorance and "better safe than sorry" politics talking. IE. if person asks if something is safe and they have no clue if it is safe or not, default answer is "it's dangerous".

I just visited the Medtronics web site, and I found this PDF, entitled: "Answers to Questions about Implantable Cardiac Devices;
Electromagnetic Compatibility Guide."

On page 3 (Household and Hobby Items), in the Minimal Risk column it mentions GOLF CART MOTORS.

On page 4 (Tools and Industrial Equipment), in the Special Considerations column it states:

"Maintain at least the recommended
distance between the item and your
heart device:

"12-Inch Distance
• Car Battery Charger – 100 amps or less
• Gasoline Ignition Systems – from
components of ignition system
• Gasoline Powered Tools – from components
of ignition system (lawn mower,
snowblower, weed whacker, chainsaw)
• Generators – 20 kW or less

"2-Foot Distance
• Bench Mounted/Free Standing Tools –
for motors 400 horsepower or less
(air compressor, drill presses, grinder,
pressure washer, table saw)
• Jumper Cables
• Welding Equipment
( with currents under 130 amps, see page 9)"

The Tesla contains an AC motor(s) and AC charger(s). Also, Tesla's supercharging capability might warrant scrutiny under the WELDING EQUIPMENT warning.

It looks like we would be wise to inform any passengers with pacemakers of this information.

vperl | 17 January 2015

Guess you are experts, always one in the crowd.

SC are a tad more powerful than what you mentioned. You not having the device makes you a troll saying there is no danger. Tell a person with the devices implanted in them to walk thru a metal detector and you will get loud negative response walk towards them to get them to walk thru you will get a surprise.

Hope your obbma care is in effect.

cah197 | 17 January 2015

I agree with you vperl, you should avoid Teslas like the plague. Definately don't buy one...

Red Sage ca us | 18 January 2015

Sounds like symptoms of nicotine withdrawal.

Didn't some other guy post about epilliptic seizures for his child months ago, multiple times...? Claiming that electromagnetic fields from the Model S were 'too powerful'...? I believe the general feeling here was that he was another [SO-CALLED AUTHOR] trolling. Because someone posted links to scientific results that showed the electromagnetic field generated by Model S was measurably lower than ICE vehicles in class.

vperl | 18 January 2015

Sorry, deep thinkers, unlike you and the rest of your Klan, I actually have reservation. You children just troll on topics, to attack the poster nothing more.

Sack up, get your wadded up nasty panty out of your whatever.

There is grave concern, that this new teck, the massive SC Amps and these devices. None of these groups Tesla/device manufactures have directly addressed the interaction of this tech.

But, say what you will, there is concern .

I know your type cares little of others, just yourself.

Party on Garth

Red Sage ca us | 18 January 2015

Smoke 'em if ya got 'em.

I'd rather breathe oxygen.

cah197 | 18 January 2015

Quite, quite mad...

Dramsey | 18 January 2015

vperl, you come across as a nasty, aggressive, ignorant jerk. Since you say you can't get any answers from Tesla or Medtronics, and you sneeringly dismiss any attempt by anyone here to help, please just go away.

Larry@SoCal | 18 January 2015

The OP asked one, maybe two questions. The answers are "no".

Wilber | 18 January 2015

The Model S Owners Manual (version 6.0 for NA) on page 4 mentions that a pacemaker and model S antennas may interfere with each other. Not sure if this means the pacemaker might not work correctly if too close to antenna, or if merely the antenna may not work too well with a pacemaker nearby. Would be good to get clarification from Tesla:

Warning: To avoid any possibility of
interference between a pacemaker and
the keyless system's antennas, people
with implanted pacemakers should
ensure their pacemaker is kept at least
nine inches (22 cm) away from any
keyless drive antenna mounted in
Model S. Antenna locations are shown

Why don't you get such an implant, then sit in a Tesla while charging. Tell us how it went afterwards ok?

Timo | 19 January 2015

Jumper cables is closest analogy to SC, both are DC. SC max power is 120kW. 120kW/~400V =~300A. Pretty similar currents. Charging systems in Tesla are much better shielded so EMF should also be a lot lower.

Welding equipments cause spark. That's strong radiative source. Nothing like that happens in Tesla during charging. Metal detectors are alternating magnetic field emitters. Again nothing like that is inside Tesla cars.

DonS | 20 January 2015

Current induced magnetic fields depend more on the wire placement than on the current flow. Parallel cables are very good at cancelling each out out, so only a tiny fraction of the field is radiated more than a couple inches from the wire. On the other hand, a big loop makes a very good broadcast antenna.

Fields are measurable with simple equipment, so I'm going to ignore this topic until someone comes up with real data.

Timo | 21 January 2015

Also you need to understand that, unlike radiation, magnetic field strength drop in cube of the distance, not square, so it drops fast the further you get from the source.

vperl | 21 January 2015


Guess what got one, ICD, but you being a clod never read my posts. I did mention my DEVICE .

I HAVE reservation for MX, best one can do is refrain from being inside vehicle while charging.

ATTACKS, upon me seem comicial, like a 12 year old getting caught with hand in jar, claiming he was just counting the cookies.

Timo | 23 January 2015

You better not floor it while driving either, then the current is much much stronger and gets even changed from DC to AC before it gets to motor which also creates magnetic field.

If you are scared about charging you should be very scared about driving one.
