In a battery of tests at Consumer Reports’ facility, the Tesla Model S outperformed every gasoline-burning vehicle. “We have a Porsche Panamera in our fleet that costs the same as this car,” Jake Fisher of Consumer Reports told us. “This car is quicker; it rides better; it’s roomier. It has much more storage capacity. It’s a better vehicle.” (Source: Tesla Motors)
30 minutes to charge for a 200 mile distance for a car costing $90,000 a pop? That may be fine for city purposes but not for cross-country distances. Then again would you take a luxury car on a long road trip?
With Telsa's nationwide charging network, perhaps this not be a big deal after all.
"Still, the range is lacking (200 miles, then wait for 4-6 hours?). T"
The Tesla Model S comes in 2 models 60 KWH and 85 KWH. The 85 KWH model has an EPA rang eof 265 miles and a Tesla Range of 300 miles.
According to Tesla their Supercharger will put 200 miles of range on in 30 minutes,
now if you use a Level 2 charger yes it will take a long time, but the supercharger network is meant to allow reasonable long distance trips. It's not ideal and the Tesla is not the perfect car, it's a luxry performance car not a Model T, but, that's okay.
Add to this mix that electric car companies and support companies are going broke by the buckets. Yesterday it was Better Place that robotically replaced batteries. I think the business plan is kiltered against the electrics. One percent can buy $90,000 cars. They will not build a base. If a stripped commuter for the 5-10 mile driver cost sub $15,000 they may sell like popcorn. Studebaker went broke even though they had the coolest car - the Avanti. No buyer base to support the car company type cool. Electrics need to be Model Ts that the consumer could not afford to pass up.
I live on a highway. From time to time somone will try to stretch an extra 20 miles out of a tank of gas. They fail. Someone brings a gallon of gas, the car proceeds to the filling station and 2 minutes and $50 later they are on their way. What is the plan for electrics? Pick up the car with a tow truck, take it to a charger, wait 6 hours . . .I could see a battery on a two wheel cart that could be attached to the back of the car, plugged in and the car limps somewhere fro a charge. If the dead battery could be dropped off and another installed and you're off. I aslso can see in excess of 200 wind mills from my home. They are never all running. If a truck full of batteries could pull up to the base of a un needed power source and one hook up charge 400 battery packs for no detriment to other power users and a source to save power that was not needed else where . . Benifit to power creator, car owner, midle man trying to supply charged batteries to car owners, we have a winner. There would probably be some Obama bucks too.
What is going to happen when someone is electrocuted, burnt or killed possibly after an accident? Are all first responders told to take a VOM meter to an accident site now?
Again a good business plan needs to carve a path to success that I have not seen.
I'm glad to see that Tesla has spent a lot of effort making the creature comforts the best in the biz. For a $90K price tag, one would expect nothing less. One might ask why their competitors (Audi, Porsche) wouldn't want to spend more effort in making a better ride for their high-end cars. Keeping the driver happy with how her car handles is always a wise focus. For the 10% of the 1% that buy a Tesla, it's a great deal.
Still, the range is lacking (200 miles, then wait for 4-6 hours?). To get a mass-market car, you'll only be selling to commuters on a fixed route. The price tag better be REALLY cheap (less than $20K out the door) if they want any traction in the extremely competitive mass-market. You're asking the average consumer to sacrifice a lot of convenience in driving an electric car. We all like to come and go as we please, change our daily routes at a whim, or even drive another 100 miles without a second thought.
Even the wealthy don't like having to have a backup car for any long commutes as plans can change within minutes while the battery pack takes hours to catch up. No one likes to get stranded (even with a 50 foot extension cord in the trunk). Even for this best of all electric vehicles, a paradigm shift in the car culture is still required and this is a really big ship to turn.
too optimistic indeed...even if electric cars make up 15% of the cars on the road today, is there enough lithium world-wide for all the battery cells needed? Be prepared for conflict in south america unless there's a more abundant chemistry out there.
The linchpin is in the battery packs. Re-double the battery life (170+ kWhr) and then cut the recharge time (empty-to-full) by one-fifth (1 hour max.) and you "may" have a outside chance to displace the internal combustion engine. Until then, it's liquid hydrocarbon fuels for vehicles for the forseeable future (15 years and beyond).
It's a nice goal to have more electric cars, but there are very practical reasons why it hasn't happened before or any time soon.
Pat b, if you use your 8KW solar generation capacity to charge the EV battery, and if your system is 100% efficient, then by my math it would require 10 hours to restore 80KwH of battery charge, if that was what was needed, whiich is the anticipated capacity of a medium size EV battery. But if you drive to work and work during the daylight hours, or at least some of the daylight hours, those can't be spent charging the EV. So now there exists an inconvenient logistics problem of the type that has been bothering the EV folks for quite a while. It also is a sore point for the solar power folks.
While it would certainly be wonderful if we could make it work for everybody, most of the benefits would only be available to a small portion of our people, for a multiplicity of reasons, which include a complete lack of anything even starting to approach technical competence. And I do NOT feel that technical incompetence should be rewarded.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
