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?

Russia and Iraq etc. had and still have big time problems with copper theft. Use copters to patrol high-tension lines, etc.

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! :-)

It's a possibility, but it'll take a lotta work to pull off. I mean, how often do roads get rebuilt? It's not because they have fresh asphalt on sale! I think it has better application in downtown areas, and in rest stop side roads. Drive along here for an hour (or park) and then your back to a ful tank.

Ok, first off, I think it's science fiction. But anyhow... IMO motor ways are the way to go, rather than downtown areas and side roads:

  • It's during the long trips when you need an extra charge, not when commuting around town. In that case, simply charge over night.
  • The high-traffic motor ways are relatively easy to identify, and there are an order of magnitude less miles of high-traffic motor ways, than roads in downtown areas.
  • Electric cars "burn" more on the motor way and less around town, contrary to ICE.

Thus, with an inductive motor way, you could go across country "on a single charge". At your destination, you get around town with your battery. You may have only little charge left after a busy day, but if you make it back to the motor way, you are fine. On your way home, you do not need your battery, or it may even charge. That's my answer to the limited range of ICEs. :-P

As to the road rebuilds, take a look at the Solar Roads. This wouldn't give us charging but I think it would be a better solution if we are going to rebuild the roads at some point. (IMHO)

As to the anti-theft charging of this thread:
+ 1 for including an anti-theft charging option such as a magnetic lock. Leaving an expensive charging cable in public is just asking for theft or practical "jokes".
+1 for an alarm system
+1 for that alarm to contact my mobile phone

The major advantage an inductive road has that people overlook is the fact that it eliminates the need for power poles. With an inductive road, the power is being transmitted along under the surface of the road, and the inductive recharging is a fringe benefit. Think about it; no more power outages because some drunken idiot KO's a power pole.
Flip side of that is that if there ever is a break in the line, it's gonna be a bitch to fix.

Plus surface wear & tear, winter salting (crack, leak, short, ZAP!!), opacity increases, etc., etc. Dreams by A Ijit, IMO.

Inductive charging would be the best for all locations except for the expense of home installations. I charge my tooth brushes that way. I also wonder if Tesla (& Nissan, GM, Toyota) have considered the Lithium Titanate batteries. While about 20% heavier (for the same energy stored), they require no cooling, or heating. They most importantly charge at many times faster than the Lithium Ion batteries. And to top it off, they last at least 9000 cycles of full charging - good for 20 years or more. And, I also wonder if dual layer super capacitors would have some useful application in EVs. To completely protect against theft, I would suggest snipers with rifles at convenient locations.

They are working on it as we speak...

The Plugless Power system utilizes induction technology to transfer up to 3.3 kilowatts of power at efficiencies of up to 90 percent, allowing plug-in vehicles to recharge as quickly as they would with some Level 2 conductive (wired) chargers.

My 'rithmatic sez that would take about 20 hrs to charge a Roadster fully. Hardly equivalent to a Level 2 charger.

Yep Brian. The lower current level 2 chargers are supposed to provide more than twice 3.3 kW, and the NEMA 14-50 (at 40 A) gives 9.6 kW.

But, inductive charging is really nice for things like toothbrushes, where there's a possible of contacts getting damp. I wish Waterpik would make an inductive version. My cordless Waterpik starts decreasing its functionality after about a year. OTOH the Braun toothbrushes and Philips Sonicare have inductive charging, and they last for years of effective use.

I like the idea of charging cables integrated into the outlet, so the cable is the property owner's responsibility. But there will always be situations where you want to charge someplace there is only an electrical outlet (whether 120 or 240) and you need to use your own cable. For those situations, a lock at the car end is a great idea, whether it be a mechanical key or a smart key system.

You may be skeptical, and useful applications may seem limited with today's efficiency and charging rates, but I would still say inductive charging is here to stay (and to improve):

Nah, it'll be scuttled by RF-obic Electro-Gweinies afwaid of the waves! Jiggling their pweshus genes and hormones et al.


stop cross posting stuff from the lpp web site, please!

I think they might have hidden the charge port in front under the hood of the Model S, since I can't see any signs of it on recent pics of the Alphas. Then they only need to make a small path for the charging cable out the front. Maybe with a clamp to protect the plug if someone pulls it. Putting the charge port under the hood will protect the cable from theft or disconnection + bad weather and water/ice. It will also make it possible to store the cable in the same place so u don't have to first get that out of the boot and then go to the charge port.
Anyway, this is just a guess.

Volker P;
Say what? I have never "cross-posted" stuff from the LPP website. I've posted occasional links, or made comments, but they are entirely unique to this site.

Perhaps you don't know what the term means.

my apologies for a joke gone wrong.

Maybe may vision of charging highways (="infinite range" for EVs) has just become a tiny bit more feasible:

For a demonstration of power sent through the air, see the TED talk here:

First sorry for not reading all comments, someone might have had the same idea.
Tesla, why don´t you put a "hook" to the door close to charging port. When driver closes the doors, cable will go thru/below the hook and will be locked to the car and cannot be stolen without cutting the cable. Simple, easy and cheap without and additional gizmos. Please feel free to use the idea but remember to give me some additional extras for free in to my S model....

Elon made a remark in some interview, something like "you won't be disappointed", as if the charge port on the Model S might provide similar wow-factor like those door handles... I am pretty curious what they have come up with, an I hope they have solved the problem in a particularly clever way (even though the charge port location is debatable). In the same way he mentioned that they want to keep some surprises for the final release, so maybe we won't learn the details before the cars are actually available in the stores...

+d, for Brian H

Heh, EdG; can you imagine the EMF-phobics if power was broadcast/transmitted thru the air? Exploding heads everywhere.

Not to mention the mobile phone meltdowns when people walked through the 'beams'.

Seriously, the losses of such transmission are a high price to pay. I predict limited or no implementation.

Back around 1980 I asked a new mother - wife of a friend of mine - why she avoided using the microwave oven for the kids' food. She said something like "in twenty years we'll know what dangers this thing causes". I told her husband, an MIT graduate, to explain that all it was doing was shaking water molecules, and it was inherently safer than cooking on a stove. She would have nothing of it, and he didn't want to start an argument!

There are lots of examples of how fear of the unknown has caused far more irrational behavior, sometimes at great cost. What are the chances that small, safe nuclear reactors will become commonplace in the U.S.? Practically nil for the near future. Staying the course - importing huge amounts of oil - is so much more palatable. Go figure.

It's now 30 yrs. later. Check back with your friend and see if she still avoids it! Enquiring minds want to know ...

1) The kids are not infants any longer, so heating baby foods is not the issue any more. 2) They're divorced now (big surprise! not.), and I have no desire to track her down.

Some things remain a mystery... Life is never completely understood.

Well, that divorce wasn't huge mystery, I guess. MIT graduate with clueless blonde. I hope that kid inherited brains from your friend.

Don't let your imagination run too wild... She wasn't blond, nor absolutely clueless: just way too "hard-headed".

And "the kids are alright".

Yeah, had lots of experience with a wife immune to fact. Once an opinion formed (on any basis), it was game over. Bright enough to come up with some truly astonishingly paranoid ones, too, societal and personal!

Fortunately, never got the idea that microwaves were able to render food radioactive or toxic, though. ;)
