Tesla's United States California factory quest – Tesla, Model S-IT information Tesla's United States California plant treasures
Tesla, from last year to this year's share price soared on the Internet at the same time fire-fire, the Silicon Valley electric car company face tenacious resolve into China's trademark policies, pricing policies, incentives and financial programmes began to steadily. First-time buyers through rental real estate show recover the purchase cost, one of the first owners are big brother information, such as the Internet will undoubtedly make it fire, "Tesla" has become a phenomenon.
In early June, through to United States California San Francisco Developers Conference WWDC Apple opportunity, reporters tried to contact him about the same in United States of Tesla's Silicon Valley company, hoping the Super charging stations in California to experience the Tesla Model s factory visit and Tesla agree in a very short time all of our reporting requirements.
Pure-electric hatchback looks
As EV, special Republika pulled Model s structure Shang maximum of features is using clouds in chassis Shang of battery drive, and no traditional of within burning engine, and shaft,, so in traditional vehicles ahead engine cover inside originally the placed of engine location, Model s can has a extra of storage real space-"Qian back box", Tesla said Model s in collision Shi can than placed metal engine of traditional models absorption more of energy so more security.
Model s is a four-door hatchback Coupe, trunk lid and rear window are one, United States Edition models can set off visible optional after you open the trunk hidden two child seats, so that the vehicle can seat 5 adults and 2 children. Do not take the person's words, the trunk space is large enough.
Another highlight of this car is the large panoramic glass sunroof, Tesla says it can block the visible light and heat 81% of 98%. When the skylight completely open, air circulation is adequate, but closed the last few moments, noise is a bit scary. Similar to a part of the super sports car, Model s-door handle with keys close automatically when a pops up, automatically shrink into a moving body plane and reduce air resistance.
Model s rear end look can find and ordinary cars of distinction: there is no exhaust pipe, it may seem strange for a performance model, but the 0 emission cars per hundred kilometers is 4.4 seconds (P85) and 5.6 seconds (average 85).
Tesla Model s Interior is most characteristic of this 17-inch multi-touch screen, it is featured in Silicon Valley, California. Through this screen can be vehicles of all operations, including air conditioning, navigation, audio, reverse video, it is very powerful, even through the built-in 3G network to surf the Web. But big-screen compared to the traditional button-down, blind action and there is no advantage, so best not while driving.
Another Model s dashboard is also full of liquid crystal, this is the limousine of the mainstream. Central dial displays speed and kinetic energy recovery values, can show the navigation on the left, the right can display all kinds of information such as air conditioning, FM, sunroof open.
In quiet among flared
This give us a test drive of the Tesla is a gray, P85+ up to the Model s models, and comes with all optional configuration. It sells for more than $ 130,000 of the factory, the price in the United States if you do not buy P85+, you can choose models with BMW M6 Porsche 911 GT3 or a Nissan GT-r, Model s as a whole in the United States position is still quite high.
Model s close to the width of 2 metres, nearly 5 meters in length, wheelbase 2959 mm, is a fairly big car, and BMW 5-series, the Audi A6 is similar. Just opened up, can feel it more than 2 tons of weight and size; after a period of time, when you get used to it, feeling very comfortable driving, especially the optional air suspension models, makes the center of gravity lower chassis can be reduced at high speeds and very sound feeling, corner.
While body weight, but Model s don't shift is pressed "Accelerator" directly to output maximum torque, P85+ was surprised by the speed of 0-96 km/h in 4.2 seconds is the official data or even too deep tread "Accelerator", because it is very easy to exceed United States high speed of 65 mph speed limit, although in practice driving 75 miles or so, the Americans are.
Due to the abundant power and direct output, need to overtake and simple line, and occasionally on the road more than a Mustang and other traditional high-powered sports car, really make people feel is beyond this age. Indeed Americans and turn signal and Horn to the usage is very low, they drove almost shunned and lines, walking a straight line now.
Addition, relative Yu traditional car, Model s in driving Shi also has a details, is release "throttle" Hou, will automatically brake and non-General car as just no power needs stepped on brake, Tesla called "kinetic energy recycling", is using electromagnetic induction principle release "throttle" Shi let drive machine reverse, to battery charging of while also can improve brake effect, so in part situation Xia can with release throttle to instead of stepped on brake, such even can only with a pedal on can drive has, But brakes still need the brake pedal.
Because the United States very high speed to road conditions, just basic formation can hold up traffic at high speeds, although there was no engine sound, but up to 65 miles per hour above the tyre noise is quite big. But highways are free, poor road conditions or extenuating circumstances. But very rare, new tarmac, high-speed Model s greatly reduced tyre noise and quiet a bit exaggerated. In the case of most of the roads in the country better, Model s owners should be able to feel one of the biggest advantages of the good: extremely quiet.
After stopping the car, next to a group of United States young people saw the P85+, began to gather around, said the first time I saw "+" version and stuff, Tesla's birthplace even in United States, California is still very fresh. Even inferior light, next to Uncle opened the window and held out his thumb.
Permanent free Super charging station
Tesla called Super charging station is charged on most fast-charging stations, from Tesla's website data, Model s-85KWh-filled half of the 20 minute, 30 minute charger battery Model s can travel 270 km. Also, Tesla owners in Super charging stations are completely free of charge. Super is the rationale for charging station DC bypass through a special cable car entered directly into the battery charging equipment and the voltage and current are quite high, so it can reach several times the normal alternating current charging rate.
North America currently has 94 Super charging station, allows Tesla owners from the United States West Coast to the East Coast, and Super charging stations for Tesla owners are completely free and open. Its power source is generally through a combination of solar and conventional power grids. Tesla says the future will be to build more solar awning Super charging stations, both against the Sun and environment.
Tesla's data show, Super charging stations have been providing 6.43 million kilowatt-hours of electricity, has been providing 29.42 million km journey, had 2.78 million litres of fuel-saving, 7 days have been Super charging station with 5,909 vehicles. Meanwhile, Tesla factory is located in Fremont, California is the highest utilization rate Super charging stations. According to Tesla's plan, by 2015, the Super charging stations covering the entire United States and Canada region.
Tesla completed a Guinness a while ago, two Model s to use Super charging station, spent 76.5 hours each fired 5543.2, from the United States West Coast, Los Angeles to New York on the East Coast, two other cars with power consumption of 1197.8 degrees.
We started in a super outlet charging station experience, Park the car charger connected, found the charging voltage starts to rise then current starts to rise it is our Model s surplus electricity is about half, machine will last, 134 miles (215 kilometers).
Soon the voltage and current 369V and 179A, show the charging speed of 132 mph (211 km) per hour, started charging after 5 minutes, had filled in for 19 miles (30.4 km) miles, instantaneous charging rate at an impressive 249 mph (398 km/h)! At this rate, half an hour can be filled with close to 200 kilometers, the Model s in the middle of a long trip when the charge is sufficient.
In the United States two days after the opening of Tesla, 416.2 km electricity counter display 88.8 degrees, charging 5 cents for each kilowatt not calculated loss cost as low as 10.7 per hundred kilometers. Because everything is in fact Super charging station, we didn't spend a penny.
That Tesla has just begun on the Chinese mainland to deploy Super charging station, quite a long period of time most of the owners had to use their HPWC to charge (High Power Wall Connector, high walls), its arguments are 32A and 220V. Charging rate is relatively slow, probably will seriously consider the 38 kilometers per hour, and just Super charging stations compared to 398 km/h speed, was a one-night return to liberation. Convenient Auto Recharge at any time as long as there is a fixed parking spaces, recharge slower at night but nothing serious, and when I travel is the big problem.
Explore California's Tesla factory
Trip the next day, we went to Tesla production plant in Fremont, California. Tesla plant is bought back from GM and Toyota, the current Model s-line is simply taking advantage of the large factories of 20% of the area. Factories as well as Tesla's next a direct store delivery centre, not far away there is a Tesla repair service center.
With most cars, Model s production process consists of four main parts, 1. stamping production of individual components, 2. connect the components into the body, 3. body painting, 4. installing additional components to the body (with motor and battery components).
Tesla's body the metal parts of 97% aluminum alloy is used, because light-weight electric motor can make it more efficient. After ramming machine cutting of thin aluminium sheet metal stamping required for Model s thickness of various shapes of parts. The huge press machine has four groups, multiple layers of thin aluminum alloy plate by robot arm in four groups of machines stamping in turn passes, will be able to generate a variety of different shapes of metal parts.
Connect done stamping components will then be handed over to robots, Tesla factory staff said at least 150 robots. Connection's first step was connecting piece welded section steel chassis and up. Then the entire body of welding, bodywork in 14 major components, connect according to the region.
Body weld finish will send another workshop for painting, paint over after entering the last stages of vehicle Assembly, vehicle Assembly, the first step is to install the Tesla Model s signature panoramic sunroof, if consumers buy, its price is 21900 Yuan. Installation method is a robot based on the roofline photo shoot glass skylights and precise in location.
Then to put the vehicle's Interior, seat, drive components, wheels and batteries mounted within the frame of the chassis. Tesla's Powertrain – motor and rear wheel brakes, body mounted rear from the bottom, there is no conventional internal combustion locomotive engines, traditional shaft. Due to the motor and the battery is at the core of Tesla's technology, this part of the workshop and is not open to us to visit. Just seen the finished product. After assembling complete, Model s entered the factory testing stage, then taken out of the factory, waiting for the United States local customer pick-up, need to export transportation by cargo ship around the world.
Tesla's future path
Tesla had fire-fire in China, at the same time miles away Nordic country Norway can be described as Tesla's European base, due to Norway for pure electric vehicle charging free parking free of charge, and incentives such as tax breaks, on sales up to about 1500. In most States, however, has just started the development of electric vehicles. While the Outlook is not bright enough, but Tesla is certainly determined to move on.
Tesla later this year will introduce a backdoor to Hawk wing's seven four-wheel drive electric SUV models Model X,0 to 96 km/h acceleration time of less than 5 seconds, is now in China's official website to receive 30,000 yuan deposit reservation, book now the estimated delivery time is the summer of next year.
Within the next few years, Tesla will also launch a cheap electric car, accelerate the popularization of electric vehicles. Meanwhile, in order to reduce the cost of batteries, Tesla will be in United States GigaFactory siting a battery factory, is expected in 2017 batteries cost more than 30% less in 2020, an annual output of 500,000 sets of batteries used in electric current Tesla Tesla and Panasonic battery supplier has confirmed the common construction of the battery factory.
At the time of closing, Tesla announced that it would open to all of the approximately 200 patents, with other companies to develop electric vehicles, and said it was "no business of any bona fide use of Tesla technology to initiate proceedings. "Once again, shocking.
