If you haven't thought of it already... Ideas for Tesla

edited November -1 in General
I don't know if someone has already created a Thread like this but I would like to start a Ideas-Discussion about Tesla and its Products.

So for example:

Charging a Tesla Vehicle through Inductive Charging
- right now you have to charge it through the plug/port on the side of the car
- it works and its simple enough, requires to deal with a cable

Why not charge your Tesla using a inductive charging station?
Check out here what Inductive Charging means:

So the most convenient way to charge your Tesla is to put the Primary Coil (in the charging plate) on the floor of your Garage and have the Secondary coil under/or in the front bottom of the Tesla Vehicle. Once you drive over it and park your car in your Garage it will charge the Tesla, no need to plug anything in.

They have this for phones already, but you have to buy some special case for it, which makes the phone bulky. I can envision this for a Tesla Vehicle in my own Garage (if I ever have the chance to buy one :D)

So let's see if anyone has similar or new ideas, and if this community is willing to discuss ideas on here.
Have a wonderful day!

    Wireless induction charging does have a cool factor and may be slightly more convenient than plugging in a cable, but it would come at the expense of lower efficiency (slower charging) and higher installation cost, which are pretty large obstacles to overcome...

    and also presumabley a bigger hardware footprint on the car, but maybe not, I dunno

    If Tesla can make a 300mpc car happen they prob can make that happen too :D

    I am just researching more about this technique and found that Qualcomm has tested wireless charging in London

    But I did see the lower efficiency which could be improved if there is a demand for something like this. I just thought it's a cool idea.

    What other ideas do you have?

    Inductive charging for the Tesla would be really inefficient. For the phones the coil is on the back of the phone and it is touching the pad so the gap is quite small. With a Tesla parked over the coil the gap would be far larger. Also, with a phone the loss of efficiency is no big deal since the amount of power is fairly small. With the huge amount of power required to charge the car it is a much bigger problem. Also, if there are any iron based parts of the car they would be affected also by the large magnetic field.

    The EV1 had inductive charging. You still plugged in a cable, but there was no metal to metal contact. Instead the plug was paddle shaped and had an inductive coil.

    I don't know what the efficiency loss was, but it might have been small given the very close contact and precise alignment.

    You might wonder what the advantage was, though. I am not sure. I can think of lack of contact wear or corrosion and higher safety (or feeling of safety), when charging in the rain. I can't say that either of these is a significant advantage in real life.

    Yes, and I would also wonder about the data link between an inductive charger and the car. Would it be as wideband and robust? Hard to imagine.
  • edited November -1
    The main advantage of inductive charging is outside the home where the lack of a cable means copper thieves have nothing to steal. However, the logistics of having an inductive charger that could work with a wide variety of cars and the higher costs of charging due to the inefficiency of inductive charging are likely to be an insurmountable barrier for the foreseeable future.

    I was simply thinking of it as a home or parking garage addition. Where you could simply drive onto it, or up to it, or something that moves up to the bottom of the car if you roll over some kind of sensor. The car would always be topped off and a built in WiFi module can be the data link (if the GSM which is already in the car isn't enough)

    it would simply be for convenience, I could see it applied at the charging stations at well.

    Regarding the efficiency, the techs have to figure that one out!

    I'd like a two door model S.
    I'd like a pickup truck, think El Camino.

    Well how about this use as tinting for any ev vehicle which actually Has pv cells in the tinting to keep charging the ev vehicle
  • edited November -1
    Trivial and expensive. A few watts, when you need kilowatts.
  • edited November -1
    Few watts could be enough to stop discharging while not used. Infinite time at parking lot without plugging in. For charging, especially while driving, it would be pointless effort. Real cars are not "solar racers" which are basically just mobile extremely aerodynamic lightweight solar panel movers in bicycle wheels.

    I know this doesn't refer to inductive charging.

    I think it would be great to have "solar panels" on the top of the car, like the roof, hood and trunk lid. I see that a company "Alta Devices" now makes a 23.5% efficient solar cell, and a company "SunPowerCorp" is making solar panels with that efficiency. I see that they have a 327Watt panel that is roughly 5Ft by 3 1/2Ft. Also, they make a 435 Watt panel which is roughly 7Ft by 3 1/2Ft. So, maybe one could extend the driving range with a 400Watt solar generating panel(s) on the car (integrated into the hood, roof and trunk lid) while driving. It might add maybe $1500 (I'm guessing on the numbers) to the cost of the car, as an option, but if it gives another maybe 50 miles to the range? it might be worth it. And, help keep the battery charged or slowly charging, while sitting in a parking lot.

    lotsa threads on this. But, for example, the Karma's solar roof cost $5k or so, and generates a couple hundred watts. Shape, angle, time of day, parking in the sun, etc. all considerations. Generates maybe a couple of miles a day. Would take hundreds of years to pay off.

    To get your 50 miles, park in the direct sun, all day, for 2 weeks or so. In the summer, as close as possible to the equator.
  • edited November -1
    It takes 20kW to keep going at 60mph. 400W is 2% out of 20kW. 2% out of 250miles is 5 miles. 400W is overoptimistic value. You would not get that because angle of the Sun, unless you drive at noon in desert at equator. In real life in sunny day somewhere at mid-US you might get maybe two miles worth power extended range if you are lucky. Parked you might gain something like 2kWh / day with that panel.

    It's just not worth it. Tiny panel that just keeps charge state constant when not plugged in could be worth the money, but anything bigger than that would be better used to put in more batteries.

    The only thing a solar panel on the roof is good for is running a ventilating fan or some similar non-critical low power accessory. Even then it's not even remotely cost efficient. Solar panels on the roof of your house are a good idea, on a car, not so much.

    here's an idea: auto drive. I would think a car with so much computer power as the Tesla, it would be great to include some of what google has been working on. also with computer auto drive, cars on the freeway that have this could link up and form a "train" (may be magnets in the bumper) and go faster with less energy.

    Not even close. Check out the gear the Google car carries.

    Ideas? More colors!

    The main colors that seem to be missing from the Model S

    Light Blue
    Sea Green

    I'm sure there are more, but these are other colors I would expect to see.

    Chameleon? Neon green?

    Isn't "sea" supposed to be blue? Sea Blue (looks like there is Sea green paint also. Weird).

    the google car packs it all into a prius...a car that starts life without the kind of computer the Model S already has. sure its still going to need much more, but the Model S has lots of space throughout. the space in front of the firewall for instance. this is a long term goal, it just seems like this would be the right kind of forward thinking that would fit with such car. also there has to be a better solution to that salad spinner on the roof!

    Inductive charging for the 'Supercharger' stations?
  • edited November -1
    @Fog, I'm sure there are better and more unobtrusive systems that that "salad spinner". Google just goes with what works for now, and worries about hiding it later.

    I don't think this is any more a technical challenge, we already have all kinds of sensors that are better than human eyes, and computer processing power is more than adequate to react faster than humans do. I think the problem is in software, making that tech to think as well as humans in unexpected situations is not that easy task. Making thinking "fuzzy" so that it can adapt and still do what you want it to do and not something else.

    Think "Christine" combined with Hal 9000.

    Considering even the side mirrors add 5% to the S' drag, or X' drag, and regs don't even allow rearview cameras yet ... Of course, Google has way more clout to throw around and strings to pull than TM.
