No doubt this car is one of the best car, However electric car technology is becomming very common these days . But it is not that easy to charge electric cars, at your homes you can directly connect your car with some current point but on public places EV systems electric vehicle systems are becomming common these days .This system comprise of a computer and car can be charged through it although the computer contains all the information of the customer . I have heard that hackers are hacking those systems to get te information of the customers .This means one should take precautionary measures for the security of these systems .
I own a Model S and the battery is already designed to swap out in under 5 minutes. The problem is the cost of batteries and how the car is sold. Right now you buy the battery pack along with the car. The bigger the battery, the more the car costs and the farther you can go. Am I going to want to change my battery pack out for another one that may or may not have been cared for as well as mine? Not likely. There are a number of companies that have attempted or are attempting battery swapping and my bet is tesla is waiting to see how that goes before starting their own solution. That being said, on May 10th Tesla made a filing with the SEC that said in part: " Among the factors discussed was its ability to "rapidly swap out the Model S battery pack, and the development of specialized public facilities to perform such swapping, which do not currently exist but which we plan to introduce in the near future."
You just never know with those guys. I've woken up on some morning to find that they have downloaded an upgrade to my car while sleeping. How cool is that? If you can afford one, go get it. I guarantee you won't regret it. If not, at least buy some stock because these guys know what they're doing.
There have been numerous attempts at that. My first real encounter with an electric car (back in about 1994) was "Snow White" made by Bob Schneeveis. Snow White was a race car that used 20 car batteries as the power source. Bob had built it to allow quick changes of the batteries. The body on each side was hinged so that side and top surface lifted up when raised and the contacts to all for the battery terminals was spring backed copper plate. When the wing lifted, there was no electrical contact with the batteries - only a tray of batteries. The battey tray dropped in on some clever wedge shaped rails and could be pulled out with a floor jack to lift the tray and roll out. He actually had a nice rig set up with fire hose and compressed air to quicky inflate (and lift), then roll out. Roll in a fresh tray and close the wing and you are good to go. A pit crew could swap out the two trays in several seconds.
The main drawback that I see for removable batteries is that they are too expensive right now to be feasable. Are you going to swap out a $40K pack for some unknown pack at a "gas" station? Also the logistics of storing hundreds if not thousands of fresh packs to swap out during a day and the sub station that would be needed at that "gas" station to charge those packs for the next swap would be a bit daunting.
For that type of concept, the replaceable electrolyte concept is a better route.
I think the comment on 2 cars was more for 1 electric and 1 gas powered (or hybrid) than 2 electric. The electric used for most closer to home uses and a gas powered one for the long trips.
If batteries are the pivot point why aren't they suspended on the bottom of the car with a dissengage / re-engage method so the battery could be swapped out faster than you can fill a gas tank? A recharger could charge on off hours and you would have limitless travel capacity. I laughed out loud when the article said for trips you'd need two cars duh at 200 miles you'd have two dead cars. Where is my single seated electric that weighs 500 pounds, built exclusively of carbon fiber, takes 1/2 a parking space, comes and goes w/o recharges?
Good that you do this type of calculation. Also, consider the following: All Tesla 85kW/h battery packs are guaranteed for eight years. When you need to replace it after that, the cost is $8,000 (right now - not sure about eight years from now).
Anyone purchasing an electric car must consider this - yes, a combustion engine can let go, but it can be serviced/replaced far easier at far more locations for far less cost than a battery pack can. We're just at the beginning of this; if in nine years there is a rash of battery failures on Teslas, these people are not going to be very happy to shell out that kind of money to keep driving their car.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
