Has Tesla included in it's design of vehicles any protection against an EMP Pulse?

Has Tesla included in it's design of vehicles any protection against an EMP Pulse?

An EMP (Electro-magnetic pulse) has the potential to throw any recipient country back to the stone age. Now, to be fair, EVERY ICE CAR that I know of would be totally incapacitated if this were to occur-it would be dramatic. However, I am curious, because of Tesla's immensely superior design, whether Tesla Engineers have thought of a way (wrap electronic in Faraday Shielding?) that a Tesla Vehicle could remain functioning...?

Tell your mommie, you need her to order tin foil, and a new set of science fiction books.

If there is a emp, I suggest you might not see many more days.

But, being in mommies basement might save you for a few weeks.

Duck and cover. A phrase I learned in grade school .

There wont be any electricity after an emp attack.... everything fried.... so why bother

Red Sage ca us | 15 janvier 2015

Nope. None whatsoever. In fact, it uses tires made of ferric materials instead of rubber compounds to make sure occupants are fried in a lightning storm.

HappyCustomer | 15 janvier 2015

Interesting question. From an engineering stand point, it might be easier to build a faraday cage around an electric car's motor and battery to protect the drivetrain than to do the same for an ICE's electronic parts. Using magnetic coupling to transfer the energy generated from the motor to the wheels would make it relatively impervious... but I'm sure it can't be THAT easy!

Red Sage ca us | 15 janvier 2015

Plus, after the cars are built, and roll off the assembly line, a powerful alchemist magically transforms all the aluminum to copper to complete the path to ground.

AA_4_Tesla | 15 janvier 2015

I don't think shielding your car is really the main concern in the event of a massive country-wide EMP. Duck and cover maybe.

DonS | 16 janvier 2015

Just the radio antennas for FM, cellular, Wi-fi and XM satellite present an easy path for EMP to enter the car body and take down every computer and radio.

If you are worried bout EMP, keep a 1960's muscle car in your garage because everything except for the radio will still work . Anything with a computer (circa early 1970s) is not going anywhere after a major EMP hit.

I keep bicycles in the garage besides my P85 and folding bikes in the car just in case. ;-D

Faraday cages work. Watch any of the Tesla Coil concerts to see people in mesh boxes or chain mail taking direct hits without harm.

makatron | 17 janvier 2015

one of the funniest threads in the Tesla Forum :P

*grabs tinfoil hat* ahem... you can't never be secure enough

Larry@SoCal | 17 janvier 2015

60 years ago my instructors said, "Don't say 'AC current" or 'DC current"
because you are saying 'Alternating Current current' and such.
Avoiding this redundancy has followed my all my life. ATM machine, VIN number, GOP party and on.
"EMP pulse" means what? Electromotive Pulse pulse.
If you misuse the term, some people will not be impressed with your argument.

Red Sage ca us | 18 janvier 2015

If it has an FCC APPROVED label on it that means it is susceptible to EMP.

vperl | 18 janvier 2015

Heard Soon is sending out his herd of Unicorns that were not eaten by the Squatch to distribute 5 gallon barrels of water and MRE to survive.

Also, each Tesla if instructed
by new owner has a roll of tin foil in frunk .

sousa.julio01 | 18 janvier 2015

Isn't the vehicle it self a Faraday cage? Just asking ^^

ElectricSteve | 19 janvier 2015

A typical question that has not been thought through.

Event 1. car is charged 100%
Event 2. a massive EMP occurs (damn North Koreans). Everything in the entire region is fried... ...but the car still works because of "Tesla's immensely superior design, ")
Event 3. car owner drives 265 miles, battery is depleted.
Event 4. car owner seeks a charging device and finds one. Opens charge port and plugs in cable.
Event 5. car owner discovers what such a massive EMP actually does...

I mean really dude?

Nexxus | 19 janvier 2015


People really do worry about the wrong things don't they?

Forget that no automobile will work ICE or BEV. All the batteries will be shorted to be of no use. Any electronics unless strictly shielded against an EMP will not work afterwards.

And sooooo many worry about the things they have no control over either...

ElectricSteve | 19 janvier 2015

"All the batteries will be shorted to be of no use."

No no, you are forgetting "Tesla's immensely superior design, "

The only vehicles that will survive and keep working are Tesla's. !!

Pay attention next time Soldier !

Brian H | 19 janvier 2015

Max power to shields, Scotty!

Timo | 20 janvier 2015

Diesels will run. There is no need for electrical components to run the engine if you just manage to start one.

Anemometer | 20 janvier 2015

I can't go to the store and buy food, I no-longer have a job as all he computers are down. Still at least my Telsa works.

Pure WMD EMPs are just sci-fi anyway. If there an EMP Pulse big enough to take down the grid it will be accompanied shockwave and a fireball that will destroy everything for several miles.

That's unless you are a specific target and they want to use an Non nuclear EMP on you. Much lower power and needs to be targeted at something.

If you are a prepper considering a Telsa - a better bet would be a bicycle with a trailer. 1 for each family member.

blue adept | 20 janvier 2015

If my car goes down due to an area specific/directed EMP, I'm calling the Pentagon and reporting an active terrorist cell.

Nexxus | 21 janvier 2015


EMP = Electro-Magnetic Pulse.

And I don't care which technology automotive makers use (BEV or ICE), even diesels won't run if you don't have a battery to start the thing.

Even Tesla's batteries aren't shielded against an EMP. It would take 1/2" of lead shielding around 100% of the battery unit to keep them from getting shorted.

When the US set off the hydrogen bomb @ Bikini atoll in the 50's everything electric stopped working, cars included, for 100's of miles diameter unless it was specifically shielded against the EMP.

hpjtv | 30 janvier 2015

@Larry@Lancaster-CA while I agree with you for the most part, you wouldn't say EMP pulse cause it means EM pulse pulse, for AC DC, you have to distinguish it from voltage vs current (Vdc, Vac, Idc, Iac).

TV | 4 février 2015

Wow, lots of sarcasm and jokes. It is a good question. USAF War College teaches that the #1 threat to the USA is no longer Biochemical (never was atomic), but now EMP Pulse.

My question was sincere. Go_Peddle_4_me (@Larry ) Thank you for an excellent succint answer. That was what I was looking for. Look, an EMP Pulse is certainly not something anyone "wants" to think about, and it would certainly be a "change of life", but the question was made because of the uniqueness of the Tesla. I'm not paranoid, but I was curious. Thank you everyone.

vperl | 4 février 2015

Children, worry about some terrorist threat that includes a chemical explosive device, better know as a bomb. Or, perhaps a couple of friendly folk with a couple AK-47, that will shorten your daily grind.

Plenty other stuff to actually think about, not some electronic blast destroying your car, X-box, or what ever silly game you play in your mommies basement.

This forum is turning into a bunch of cry babies.

What else creates an EMP pulse than an atomic weapon that can take out a wide range of electronics?

JeffreyR | 7 février 2015


That thing from "Ocean's Eleven" of course. I love the scene when they steal it!

Remnant | 7 février 2015

@ Timo (January 20, 2015)

<< Diesels will run. >>

Only Diesel engines without an electric common rail can be started by hand and run without electricity.

Remnant | 16 juillet 2015

@ holidayday (February 5, 2015)

<< What else creates an EMP [other] than an atomic weapon that can take out a wide range of electronics? >>

A solar EM storm, such as a coronal ejection flare. The last one, known as the "Carrington Event", occurred in 1859; it destroyed telegraph equipment and started fires.


In 2012, Earth narrowly escaped a similar event:


According to Lloyd's of London, such an occurrence today would cause damages of some $2.6 trillion and take up to a decade to repair.


Wherefore, it is not unreasonable to expect auto makers to direct their R&D to design EMP protection.

Mr_Anderson | 16 juillet 2015

Thank you @Remnant. That's exactly what I was thinking as I read through the comments. Lots of people here seem to think that OP's comment is purely science fiction. We've seen this type of event happen once since humanity began harnessing electricity. Thus, we can expect such an even every 200-300 years based on our sample size of 1 (bad science, I know).

Many people are currently powering their teslas at home via 100% solar power. This could mean that teslas (and certain antique cars) are the only vehicles on the road after such an event. Given the rarity of such an event, the average person may not care about such a question. However, it could be a huge selling point if tesla ever creates a product for government/military.

I don't know enough about it to truly speculate, but I know enough to say that the OP's question shouldn't be considered a thing of sci-fi... research it a little before scoffing.

Juggernaut | 16 juillet 2015

Seems to me that even if the Tesla were shielded, that there would no longer be any way to charge it. It's like asking if brick houses are shielded against nuclear bombs... Even if they were, what's the point?

johnse | 17 juillet 2015

A massive solar flare/Coronal Mass Ejection (CME) such as the Carrington event would, indeed, wreak havoc on the grid--and likely anything actually plugged into the grid at the time. That's in large part due to the massive antenna which the grid forms.

A CME is a very different beast from an EMP created by nuclear weapons. The Carrington event caused a "geomagnetic storm" which is basically large oscillations in the Earth's magnetic field. These oscillations induce currents in wires. the longer the wire, the more it will induce. Also, the wavelengths of the oscillations will be very long, and thus the long transmission wires will be better tuned to them.

I think it unlikely that the geomagnetic storm would induce enough current in small circuits to cause problems.

Here's an article on the effects that have been seen in other CMEs. Note that the major problems occur in power transmission systems, long distance communications, and as interference in radio.

Also, as more of our communications system goes optical, there will be less of an effect there as well.

vperl | 18 juillet 2015

One has to be concerned with the mental health of individuals that worry, fret,or otherwise carry this thread forward.

EMP , really that is ones actual despairing thoughts?

Maybe one ought to know what actual events that would interrupt ones life.

Gee, wonder what those events might be.

But, I guess children must have a hobby.

Party on Garth.

Remnant | 18 juillet 2015

@ vperl (July 18, 2015)

<< One has to be concerned with the mental health of individuals that worry, fret,or otherwise carry this thread forward. >>

The proper amount of FUD regarding CME and geomagnetic storms results clearly from Lloyd's 2013 report. While decentralized PV power generation might address the issue, it would only do so if the PV circuits are geomagnetically shielded. Properly designed solar panels can be protected, but such a feature has not generalized yet.


However, protection against stratospheric nuclear EMP is more complicated, partly because it spreads according to the line of sight of the detonation point and thus can promptly take continent-wide proportions and partly because it contains very high intensity initial gamma radiation which can fry most microcircuits and thus the virtual totality of our electronics. A high altitude EMP can bump the entire US into a stone age, because all supplies would end within hours to a few days and could not be replenished.

Wherefore, EMP shielding is not a frivolous goal and should be pursued by all serious manufacturers of electronic and electric equipment, including autos.

rlwrw | 18 juillet 2015

Years ago when I drove up to the Mt. Wilson Observatory, I was unable to set my car alarm because of the RF from all of the transmitters, even when I held the fob right next to the alarm module.
I also shot video there, and ended up with a faint herringbone pattern in the image.
Obviously there are areas with strong emf/rf emissions that do affect some electronic equipment. Does anyone know how Teslas perform in such areas?

vperl | 18 juillet 2015

How interesting, EMP, the great concern of this forum.

Remember, Elon has embedded a large roll of Tin Foil on the drunk under the mat.

All is well in stupid land.

Why are you so angry?

Why do you feel like insulting this thread's participants?

You certainly have the option to move on to a thread of your liking. Just relax and be on your merry way.

By the way, have you looked it up yet? It's E-M-P.

Bye, bye, vperl.

@ rlwrw (July 18, 2015)

This statement and question should generate an inquiry with Tesla. We can ask it to publicize the kind and level of electromagnetic protection of its cars.

Remnant | 19 juillet 2015

@ TV (January 15, 2015)

Suggest a couple of edits for your OP:

it's design => its design

EMP Pulse => EMP

vperl | 19 juillet 2015

My feelings are hurt, you accuse me of anger, and insulting some unknown people or person, how shameful of you.

However, I forgive you.

You may be redeemable, so I offer you tin foil in various colors, and widths. Remember, those that accuse usually are the transgressor's of speech. You are still forgiven, hope your silliness, and lack of the world's way bothers you, you attack me.

Again, in whatever country you live in, you cannot shame people.

So, Hi to you.

rxlawdude | 21 juillet 2015

Nah, at least from the posts I've read from it, vperl represents the angry conservative. Xenophobic, science-hating, and probably not a particularly nice person.

Rocky_H | 21 août 2015

@g9147933, On the brakes, you are confusing something. There is electromagnetic braking (regeneration), but there are also traditional brakes. They are required by law in every car, so if the electronics went out, you could still press the brake pedal and stop the car. On the steering, I don't know about that one. The power steering assist and feel is software-adjustable, but I don't know if that quit, if it is still physically linked somehow so it could be steered with some effort.

Timo | 23 août 2015

I'm not sure if they are controlled manually. Every new car has ABS, which means there is a computer doing things somewhere between your foot and the brake pads. Same applies to ICE. In all modern cars pretty much everything is monitored and adjusted by computers more or less. You can stop a BMW using EMP. It just dies.

If there was an EMP strike there would be no way to charge your Tesla vehicle so that would be pointless for it to be EMP PROOF.
