[QUOTE=Crimor;41115765]Is it bad that I want to mount a lazy chair to the stripped down version and make it control with like a ps3 controller or something? :v:[/QUOTE] Would be bitchin' if Tesla sells the stripped down version, along with necessary electrical control components, so you can use it to design and built your own body to drop over the frame. I would be all over that shit.
[QUOTE=wanksta11;41114623]This car is a huge success, the problem is the price.[/QUOTE] Like anything, it'll come down eventually. Hopefully this is the future and we can work on removing what pollution we have in the air already.
[QUOTE=FordLord;41115369]I somewhat doubt Tesla would take the time to check cells and such, most likely just throw it on a charger and call it good until someone complains. Though we will have to wait and see. They could track the person down, though if the battery does make it into someone car and performs like crap, theyll be in trouble. Propane tanks are similar, however theyre dealing with a flammable gas and are regulated more.[/QUOTE] Except they CAN'T do that. Lithium cells that are damaged are highly dangerous, so they're pretty much obligated to ensure the proper functioning of each pack. I've also wondered how bad it could be if a collision occurred with a lithium pack like that... Not saying that technology SHOULDN'T progress this way, these are just weird things I think about.
The model s battery is the strongest part of the vehicle. It forms the ridged frame of the vehicle. Its unlikely to break in a collision. The car is also completely water resistant and there is no electrocution risk in collision in the rain/water.
[QUOTE=OvB;41116705] Your car needs servicing? You get to play with a better one while they fix yours.[/QUOTE] That's just cruel.
[QUOTE=FordLord;41134418]That actually has nothing to do with it. Stock Viper does 10.9 second quarter mile. The Tesla in the video supposedly does a 12.3 second quarter mile. Basically it comes down to poor track conditions, and probably a crappy driver in the Viper. Also, stock viper has a faster 0-60 speed than the Tesla in the video.[/QUOTE] I don't think you're getting it. electric cars, an under developed and researched area of automotive mechanics, can field a car like the Tesla, which can do incredible speeds and handles really well and this is just a proof of concept that these cars are possible, are capable, and we're ready to start going in that direction. Comparing that to an age old industry and saying "welp not worth it lol dumbasses" like you are is ridiculous. This is an early modern electric car. Let's wait 5 more years and see how good a car that gets 5 more years of research and development and benefits from a ever growing and learning industry that is getting to see more and more cool developments in fields they rely on, like batteries. So, I say it again, you don't get it.
[QUOTE=Zombii;41131341]Where the hell do you live?[/QUOTE] I live in Yonkers, NY. White Plains is basically our counties capital (Westchester County). It's our manhatten, our core, etc. Anyway We have a Tesla store in the White Plains mall called "The Westchester". It's an amazing high end mall where it's all expensive brand name stores (Hugo Boss, Omega, Nordstrom etc). So Tesla fit in for the buying market of the mall. They apparently in this location are doing extremely well talking to there Tesla representatives. Anyway, You can park your car in the parking garage and supercharge it while your shopping. It's a standout red carpet area with Tesla Logo's and banners so you see it when you drive through the parking garage. Considering the fact tesla adopters have money, and the mall is an expensive mall it all adds up into one giant ball of showcase and amazement. [b]Edit:[/b] Here's an old photo of the store, Currently they only have a Model S on display with all the trims and fancy things with the acutal mechanics/battery behind it on display [img]http://www.teslamotorsclub.com/attachment.php?attachmentid=6236&d=1337867804[/img]
A point I'd like to make about the battery-checking... Even in conventional acid-based batteries like you have in your car already, it's quite easy to test how the battery is wearing down, aging, etc. by doing a simple voltage test. On a standard car, you hook up a battery tester to the battery terminals and, if the vehicle's battery isn't outputting 12-13V (depending on the battery), it's probably time to replace it or give it a slow charge. The battery tester basically just discharges the battery normally, but through a resistor that changes it into heat. The same concept applies to Lithium-Ion batteries as far as I know. Beyond checking the voltage output, a cosmetic inspection and inspection of the terminals for corrosion is pretty much all that's required to make sure a battery is in good "health". I think the argument that "they're not gonna check the batteries lol" is ill-founded. Obviously I can't forsee how they'll implement the check-ups, but the point is that they aren't difficult.

Li-Ions have the issue that they tend to have a a fairly consistent voltage so its hard to measure with 100% accuracy, since it doesn't drop significantly until its close to dying. Evidently, keeping track of Li-Ion battery health electronically is entirely possible though. My old Gateway laptop from 2006 can identify the original stock capacity (in Ah), and the rated capacity of the battery currently, and give it a "wear" percentage. And this was some cheap $30 aftermarket battery. I'm fairly sure almost all modern laptops do something similar. All the car's battery has to do is report that info to the charging station.
Perhaps Graphene Supercapacitors will become a thing and then we can stop filling our cars with incredibly deadly things.
[QUOTE=Fetret;41115402]I like the idea of electric cars, but as long as we derive energy from non renewable sources electric cars are not helping anything. Just because your car runs on electricity does not mean it is eco friendly. That electricity has to come from somewhere. I'm pretty sure nuclear energy, developed further, is the best bet we have for the future.[/QUOTE] I wish that magnets idea I had a few years ago would work, free energy! (until the magnetic field fades, then we're fucked)

Put in a fully charged li-ion cell, and it'll slowly and consistently discharge it at a fixed rate until battery voltage reached 2.75 volt. Then it's easy to calculate the amount of ampere you can safely squeeze out of the cell. Used it to "label" cells from wonky laptop li-ion battery packs with their respective capacity they had when i tore them out of the laptop battery packs.
[QUOTE=IrishBandit;41149821]Perhaps Graphene Supercapacitors will become a thing and then we can stop filling our cars with incredibly deadly things.[/QUOTE] The Tesla battery is no more dangerous than having 20 gallons of gasoline under the trunk. A Model S battery has never bricked or caught on fire, and it can be completely submerged.
