Floor mat charger?

Floor mat charger?

I was just wondering if Tesla has plans to produce a parallel charge interface under the car. Plugging in every night gets old real fast, especially for women. It would be nice to have an automatic drive on system. People are lazy.

I doubt Tesla will be able too, but I do recommend approaching the companies that make the charges and see if they can come up with something.

Remember, Tesla is bulding the cars, NOT the chargers.

"Especially for women"

What the heck does that mean?

Timo | 20 januari 2011

They get a headache. ;-P

qwk | 20 januari 2011

Headache, LOL

Douglas3 | 20 januari 2011

Lazy? Nuts.

Electric: 5 seconds each night lifting the cable off the wall and slipping it into the charge port.

Gas: Once every week or so you stand out in the howling wind, freezing your ass off while waiting for the smelly and carcinogenic gasoline to trickle into the car.

Advantage: Electric!

As for the "women" remark, fact is on average they hate to do anything mechanical. Not all women of course, but I can hear it now, "honey can you plug the car in".

5 seconds or not, doing it every day WILL get old fast.

I suppose it's not a high priority given all the other problems, but it would be a welcomed refinement to the experience of owning an electric car.

Anyway, I'm an engineer so I guess I'll just have to design it myself for now.

I find jsanok's statement so disgusting, it's beyond words. Next you'll complain Mexicans are too lazy to plug in their car or something else equally abhorrent.

ggr | 21 januari 2011

I find the suggestion equally abhorrent, whether it is addressed against women, Mexicans, Mexican women, ...

But that said, plugging in is such a trivial thing it doesn't even reach my consciousness sometimes. I plug in mostly at work, and I've arrived at my office some times and thought "gee, I don't remember plugging in!" When I go back down, I always have. It's exactly the same as pressing the button to close the garage door, sometimes I'm up the street, and can't remember closing the door. I always (except once) have.


Timo | 21 januari 2011

If you make it a every day routine boredom doesn't check in. Routines are things you do every day without thinking. Like me locking my apartment door and then wondering if I locked it or not.

If I don't remember locking it it is locked. If I remember not locking it it is not locked. There is a difference. Same with coffeemaker. I never remember shutting it down in the morning and I always have done it. (Sometimes I don't even remember drinking the coffee except that coffee pot is empty when I go for refill, but that is another matter entirely. Waking up sucks).

Women are no different to men in that respect, even that sometimes they seem to be entirely different species.

jsanok | 21 januari 2011

I can think of things like genocide or child abuse as "disgusting and abhorrent beyond words". If you think a comment that women may find it troublesome to plug their car as the same, then you my friend have led a sheltered life. Gender in product design is commonplace.

Fact is that electric lends itself to a convenience unachievable in a gas engine, effortless refilling, but instead we have designed the car to emulate the old method.

well I like the idear, as it remove range ancerity

Q: how often do you charge you car
A: every day, it takes less than 1 min, to get the cable out and connect it

floor mat: (technical)
Q: how often do you charge you car
A: never, I just park the car on top of my floor mat charger, and it is automatically charged

floor mat: (non technical)
Q: how often do you charge you car
A: never
Q: then who charges the car for you
A: I dont know, I just park it in my garage every night, and it is full the next day

Yeah another thread about political correctness. Wrrrm what's the books name? Guys from Mars and girls from Venus or something? Well the point of it was that boys and girls are different. Girls have those social abilieties and multitasking and so on while we men have all those abilities we would need if we still live in the woods hunting bears....

Strangely no women complained about being told to be different then guys in generalised way. In fact I get it rubbed under my nose at least once a week...

only porblem with the mat is the energy loss.. if you don't care I'm sure someone will make one soon with all those ev cars comming out the next years.

dsm363 | 24 januari 2011

jsanok: Plugging in the car is really easy and I don't think it's a problem for men or women. Women have figured out how to plug their mobile phones in so a car is no different. It's much, much easier than going to a gas station if you want to compare it to that.

BYT | 25 januari 2011

I'm a guy and I would LOVE to see this feature! Yes, if I drive to work or on a long trip I can take a few moments to plug my car in. When I get home, I just want to park the car and walk away knowing I am covered. How many times have you come home and just had your hands full or needed to run to the restroom and "OH, I can plug the car in later!" and you forget to?

I loved "Mark Petersen P-110" Q&A above!

jsanok | 25 januari 2011

ChristianG says: "only problem with the mat is the energy loss.. if you don't care I'm sure someone will make one soon with all those ev cars coming out the next years."

I think it is possible to design a safe system that uses electrical contacts thereby eliminating any losses. Of course an induction charging system would be the cleanest, safest way to go, but yes, there will be minor losses.

It's not like I'm proposing anything new, after all, the EV1 had the Magna-charge inductive system and that was over 20 years ago. I'm just suggesting we put it into a mat.

ggr | 26 januari 2011

The EV1 had a slot socket and you had to put in the charger, just like plugging in except there was no direct electrical connection. The problem is that the alignment has to be fairly precise and close. The serious designs I've seen for inductive floor chargers all have some sort of robotics in them to lift the charger and align it accurately... nothing like a floor mat.


Timo | 26 januari 2011

Not floor mat, but it can be into floor of the garage. If you lift the center few inches and put that "robot" there to do the align, and use resonating magnetic coils to charge then losses are in ballpark of 10%, maybe less, which is tolerable. Instead of charging 60kWh you charge 66kWh.

It can be done. Is it practical compared to very easy near zero loss physical contact plugging car into wall, I'm not at all sure about that.

Kevin Sharpe | 27 januari 2011

I really don't think a 10% loss on millions of cars is something we should consider. We should do everything possible to improve efficiency, not waste energy.... plugging in a EV is not a significant problem for most people.

Vawlkus | 28 januari 2011

A little of both.

the bonnie | 10 februari 2011

@jsanok ... gosh, I figured out how to plug in my Tesla all by myself ... it's just like the vacuum cleaner!

Bleccch. Seriously?

Timo | 10 februari 2011

Thinking of that EV is like any other electrical appliance, and if you think who uses most of them in the home (traditionally) I would believe that it is men that forgets to charge it every night, not the women.

ggr | 11 februari 2011

To plug in the roadster, you twist on the connector then slide a locking tab forward. I've lost count of the number of times I've come home late and tired and forgotten the locking slide.


MPact | 31 mei 2011

It's called inductive charging and it would be awesome to just pull into the garage and have the car recharge itself. A company called Fulton Innovation demoed this during CES 2011.

"5 seconds or not, doing it every day WILL get old fast."

I've been plugging in my electric car nearly every day for about four years now. It takes me closer to 15 seconds than five, since I coil up the cord on the wall. And another 15 seconds to unplug it. And it still has not gotten "old."

I LOVE plugging in my car. It's FUN! I imagine the electrons whooshing into my car from the Bonneville dam (where my electricity comes from) and I think of the fossil fuel I'm not burning. Yep. Plugging in is FUN. Pumping gas, now, well I HATE doing that. And it doesn't hurt that fueling a car with electrons is about a third the cost of fueling one with gasoline.

Brian H | 14 juni 2011

A third! That much? How did you figger that ratio?

daniel1948 | 17 juni 2011

Just a really quick guesstimate: 45 mpg and around $4/gal in the Prius; 6 cents per kWh and 3 m/kWh in the Xebra, but most places pay more for electricity than we do here in WA. Of course, a less efficient car than the Prius would increase the cost difference, while higher electricity rates would decrease it. It really depends on what cars you're comparing, and your cost for gas and electricity. I picked a conservative number. I figured few people would pay more than a third for fuel if they made the switch.
