charging design - please take care :)

charging design - please take care :)

First of all, sorry for my bad english, not native english speeking...

As a previous EV car owner I still wounder why all new EV cars now a days are designing the charging in-lead point on the car as it was still a gasoline car - as example most charging in-leads at placed outside the car under a normal "gasoline cap" (not protected by a lock)

This design is NOT the best - it works well then parking inside your own garage, but if you park the car outside on public road og in a puplic parking area the chaging coupling mechanism is easy to vandalism.
will your car "survive" if you park it 1 week on a public road in your capital city - down-town ?

I will forsee a lot of cars need repare due to some stupid young kid kicking to the charging outlood just for fun (or mayby by accident if to drunk), og at best just removing the changing cable by hand (no charging for your car the rest of the day/week)

A better place is INSIDE the car eg. the boot - this way the coubling mechanism is also protected from the weather - eg. snow/ice, watter, dirt ect.
most importent, no way some vandalism can happen as it will be locked away behind a lock / alarm.

- this was the way my previous car was designed - remmeber most of the time you still need to open the boot as you need the wire to the outlet (10-20 meters)

I hope it's not to late for Tesla to take this into considerations - please place it inside the car in the boot - or at least place charging coubling devices both inside and outside so the consumer can take the choise by them self.
best regards from denmark - truely looking forward for a test ride, and perhaps a new car :)

Although i do agree wholeheartedly, a medium where the cable leads from the car through a hole into the charging station is a great idea.
I still think leaving a car with a cable exposed at all is a bad idea, especially in downtown LA for example. If someone wanted to damage the cable they would, however with the internal coupling there is no option of stealing at least...

Great idea, hope it's not too late for tesla to take this into consideration, if they haven't already of course.

That is not only vandalism issue, it is also safety issue. Rescue personnel need to be able to unplug and remove car fast, for example in fire situations. Move cars out of the way and stuff like that. 220V live broken cable is a safety issue and without capability to unplug a EV fast it is in a way to move car away when needed. Even just maintenance work which requires moving car temporarily out of the way would be problematic without ability to unplug a car.

I'm not so sure that is a good way of making charging safe. For safety much better would be inductive charging without any physical contact in a parking lot, but that has a problem with high initial cost, difficult maintenance and not so good efficiency. With magnetic resonance coupling you might get somewhere around 80% efficient transfer, but not with very high power, at least not with any current techs.

Good informative discussion people.

I still wonder if it's feasable to retrofit inductive charging inside old drive through car wash stations. I see them used less and less these days, but it WOULD be a way to shift a gas station over to an electric charging spot, as well as providing protection from the elements.

Discoducky | January 23, 2011

I'm worried about this as well, as vandalism used to happen all the time with anntenas. Seeing a cable sticking out of a car is too much of a temptation for vandals. If pulled in any direction, the cord should safely detach from the car, while locked or unlocked, so as not to damage either the male or female end, the car or produce any spark.

On the flip side, it's a must have for anyone who must park on the road, so what's the best solution?

Connector on car should have a balance of ease of use, protection against the elements, longevity, security and consealment.

Just as the handles of the doors move out with a touch, maybe the connector on the car could do the same? Thus exposing a charging port that is always clean, protected and doesn't detract from the overall asthetics of having an EV (i.e. No fuel door; the Volt is a good example which has two round fuel doors).

Placement of the connector should also be protected from being damaged in common accidents, thus would need to be near a wheel or protected if the front or rear. However, you could mitigate this by having a secondary charge port in the boot that is more protected.

With all that being said: I can't wait to see how it's designed and where they put it!

How about a way to charge the car from below by just driving over a pad? Leave the pad in the garage when we drive it in to charge, pads imbedded in the asphalt or on top of it to charge. The battery is down there anyway?

jfeister | January 24, 2011

I agree this is could be a problem. There was a demonstration of an inductively charged roadster using a pad in the floor at the Detroit Auto Show. The article I saw said it took 48 hours to fill up an empty Roadster and claimed they could get 90% plus efficiency. Given it was a prototype still under development I'm hopeful the rate can be increased further. Seems like the best solution to me, plus it would would mean never forgetting to plug in your car when you pull into the garage.

I used to have a pure electrik car in the start of 1990 - or maybe not at car but a rolling device witch was driven by electricity :)
range was limited to 25 km and top speed 40 km/h....not fun but at least it could move.
anyway the "car" had the charging leeds in the boot - and it could easyly be rolled out to the neares standard plug - way convenient.

qoute:
"Rescue personnel need to be able to unplug and remove car fast"

this is not a isue as the wire is pluged into the wall or some sort of power outled - this can be unpluged from there by anyone, no need to unplug from the car dirctly in a emergency situation.

- I think I have seen that better place is looking at a way so only the owner of the can can detatch this from official charging stands - and of course recure staff aswell - as far as I know this should be manged by a "electronic key" witch also log you into the billing system - this way they know where to send the bill for the eletricity (and parking)

About being able to detacth automatically if someone forgot to remove the cable - it should not be a problem, since the car will not move unless you have removed the cable :) - if parking brake is relased while the charging cable is stil in place - an alarm should beep

anyway I see no problem with a solution where the customer can select prefered attaching point in the car - both outside or inside - but my guess is that most will use the plug inside the car - the cable need to go into the boot anyway - and leaving one end of the cable seems logical while take the other end to the power plug - infact why now a autoroll device as ssen in vacum cleaners witch automatically roll up the cable in the boot :) big smile

The emergence of fast charging public stations would eliminate that problem, if indeed it ever actually exists. More likely you should probably worry about the whole car being stolen if you're doing long term (many hours, unattended) recharging in some public place where few people are around. But those locations would almost alway be located in parking lots of shopping malls, etc. and I doubt would pose an inviting environment for vandals. Of greater concern is the establishment of standards for AC level 3 and DC charging.

I think taking a tip from the Roadster owners is the best method. Top off your Tesla at the end of each night or so. If you are topped off at the start of your day and have some errands to run, even with the smallest battery pack, you will easily be able to do what you have to each day and then make it home with range to spare. Then just charge it again at night in a secure location like your garage. The issue of vandalism is valid, but only of concern if you plan on doing a very long road trip. Plan well in advance any long trips and places you can rest and charge in a secure manner. I think it really is that simple.

Stealing a car whose entire drivetrain is run by electronics and can be locked by high-encryption electronic lock is d*mn near impossible to do, unless you tow the car away. You can't start the engine or do anything without right access codes. You need a copy of a key and pin code to drive it.

I don't think we need to be worried about theft, vandalism is what worries me (and stealing anything that isn't bolted on the car).

I am concerned about owning a Tesla S in Alaska-Anchorage specifically. Vandalism being my main concern since many people here make their living from the oil industry. What anti theft and anti vandalism systems are in place in the design? Also how does the extreme cold that we can experience here, effect the per charge distance? Very much looking forward to the Model S production!

Supergreekster | June 6, 2011

What is anti-vandalism system?

I have an idea... Place chain locked around charge cable, (cable is larger on each end so they would have to cut), then through wheel, then lock.

Anyone tried this? Kind of like a bike lock, if you are really concerned...

Seems like a locking charge connection to vehicle may be a more elegant solution to this, however...

Oh, and when have "emergency personnel" ever moved your vehicle? Mine is locked and has alarm active... They may tow away if they really want... They will still do to your EV! But this is why you don't park in fire lane!!

Supergreekster | June 6, 2011

Oh, and the roadster has a key, so does model s, so I am quite sure people will be able to steal if they really want, oh and vandalism knows no limits and has no moral compass...
