Anti-theft Charging On Travels

Are there any anti-theft measure during charging when travelling long distances? Say you are stopping over at a motel by the highway, you plug in the $1000+ cable for over night charging on a parking lot. My concern is won't the cable be easily get stolen as they are very expensive (similar to copper metal thieves ripping valuable metal off buildings, etc.) and also the car can get vandalized, while it is still plugged in unattended on a motel parking lot? I am sure the cables plugged into a car attracts more attention for potential vandals and thieves. What are the security features implemented to prevent this scenario on long road trips in an unfamiliar area?

Maybe had to do with people saying "I've got to nuke this in the microwave". Heard it over and over again.

Now, can we get back on "anti-theft charging on travels"? Because this is important to me at hotels and airports. Airports are waiting for guidance, and hotels haven't a clue.

Hi David,

Forgive me if this has been mentioned earlier, I think the solution has to rely on a basic assumption that the public charger end of the connection has to be built to be vandal-proof. Then it is up to Tesla to come up with a reasonable solution to vandal-proof its end of the connection to the car. The logical and inexpensive way to do that would be to place the plug inside the front and/or rear trunk space and of course lock those compartments. Anything more elaborate that this is going to negatively impact the ease of use for owners.

Here's a vandal-resistant proposal I ran across.

Curb Connect V2G

I have my reservations regarding how practical this approach will be to actually implement. In particular the very low slung Model S probably wouldn't fit over any typical concrete parking bumper to which this system might be attached.

How about induction charging as is done with my electric toothbrush. One set of coils in the pavement and one in the car. Only problem is scaling the current up 10,000 times or so.

The other problem is power loss, and radiation.

I don't mean it's radioactive, but any power that's lost from the Induction system has to go somewhere, thus it radiates outward, and I doubt having an unshielded microwave in your garage is a good idea.

Vawlkus;
not the same/right frequency range. The energy that is dispersed and lost turns to heat far, far away. The induction coil that captures some/most of the RF energy is tuned to the exact emission frequency/wavelength emitted.

Would you still want it in your garage? I sure don't.

It's quite safe, it isn't radio frequencies that are used there, more like macrowaves than microwaves, and magnetic fields instead of electric.

It's all electromagnetic waves. I have no idea what frequency would be used, but to be efficient there would have to be very close coupling.

Nice solution that another Roadster came up with (and I use):

You need a padlock that will fit tightly over the width of the cable and a wire cable with two looped ends.

Put the padlock over the cable, put the wire cable around your rear tire and loop each end of the wire cable on the padlock.

When the padlock is locked, the cable is secure inside and locked to your rear tire.

A very simple, effective solution. (Of course, someone could cut the cable - but they could also cut a locked cable.)

Also, use of the coulomb J1772 chargers is helpful - if you're registered with chargepoint.net, you will be notified via mms if your charging cable is disconnected.

On the Fully Charged site, there's a vid of a test drive with a full Rolls Royce prototype EV, and it comes with an inductive charger.

Inductive charging may not yet be ready for the mainstream, but it is a reality. At the airport in Frankfurt, Germany, an inductively charged EV is currently being used (and charged) under real-life conditions. Lufthansa is considering to switch parts if its vehicle fleet to this kind of technology. Unfortunately, the only source I have available is German language only:
http://www.heise.de/autos/artikel/Elektroauto-wird-beruehrungslos-gelade...

And the answer comes from a tourer:

"The charge port is in the driver's side tail light. When you bring the charger near the light it pops open. When the keys are not present, you can't remove the charger to prevent theft of cables."

I didn't see the charge port hooked up but I was talking to someone from Tesla about the cord and I asked and it is being locked in place when the car is locked. You have to unlock the car and push a button on the charge plug to disengage it.
I also saw the hinging part of the driver side taillight. Just didn't realize that it was for the charging connection.

It seems the proprietary (and handier) connector is tied in to a nation-wide placement of free high-speed Tesla charging stations. From TM's point of view, they're cheap, and cheaper by the hundred. Much better than compromising on a lower-level "standard", that it can't control.

Oh boy; a savings of $150 (electricity rebate) on a $4000 item that charges at 3.3kW. Only 25 hours to recharge the 85kWh pack!

Robert.Boston, before you start worrying -- you cannot use it with the Model S anyway: Evatran says, is over 90 percent efficient and "mimics" the J1772 standard without a cord.

I was just posting the link here to reflect the general state of the matter. IMO induction is much closer to the market than fusion (darn, did I use the F-word again?). It is still early, but activities like this suggest to me that induction charging for EVs is becoming a reality, although it may not yet be relevant for Tesla owners.

I am still wondering whether inductive charging is a hype or the future. I am not yet giving up. At some point, we *will* have inductive Autobahns! :-) (Myself, May 19, 2011)

Did you know? Inductive roads are a reality, and have been for a decade already in Genoa and Turin!

Readers knowledgeable of the German language may prefer to read this more detailed report by Heise:

Buses are a special proposition; their stopping points are known exactly, as are their size, design and power requirements. That said, I'd be happy to see the end of overhead power wires for them.

Buses are a special proposition (Brian H)

Absolutely. Which is good b/c every new tech needs some playing field where it can provide some benefit while not yet developed to its full potential. Then we can go further from there.

Some news from the "inductive roads" front:
http://www.greencarreports.com/news/1077576_wireless-electric-car-chargi...

"[...] The EVER project (Electric Vehicle on Electrified Roadway) shown on Phys.org, allows electric cars to charge through four inches of concrete--like that used on a typical road--with the vehicle's tires picking up the charge as it rolls along. [...]"

Back to the original topic of this thread, the owner's guide says (page 16):

"To prevent unauthorized unplugging of the charging cable, Model S must be unlocked or able to recognize a key before you can disconnect the charging cable."

How about a cell phone call from the car that says "Help I'm being tampered with!" Or if the connection is broken or the Model S is opened, "Help my security has been violated!"

Or maybe "help, help, I'm being oppressed!" :)

What IS that from anyway?

I know it from Monty Python and the Holy Grail.
