July 21, suddenly received a letter of invitation from Tesla, lucky enough to get invited to the July 29 Gigafactory in Nevada Reno Super factory opening ceremony. Excitement, to book a hotel in Reno, while planning the trip, first driving Model s nearly 1000 km round trip mileage, what would not the same experience?
Embark on a journey
From Bay district starting, to Nevada of Reno has 450 km, as based version of 60kWh, design mileage is 340 km, so midway must need charging, from Bay District to Reno along has near 10 a Super charging station, I select has Midway of Roklin as relay station, using Model s of navigation, displayed arrived Shi will remaining 20% power (actually this estimates is conservative, actual arrived Hou also remaining 40% power):
Due to the automatic driving assist Autopilot has fully experienced before this addition to ramp up and down, across high-speed travel is via the automatic driving, still left a very deep impression on me: both turns, change lanes, acceleration, deceleration, following are very good.
Rocklin Super charging station power, 8 post is filled, it seems to me that to Tesla owners participated in the activities:
Plug in the cord, Rocklin Super charging station next to a shopping mall, just Tesla lunch App tip charging is complete.
Phone displays 40 minutes rush better, charging power 98kw, it was pretty fast:
Then continue straight ahead to reach Reno Nevada Casino City, when the fast, front of Thunderclouds, and sure enough, 10km from factory when he encountered a thunderstorm, but the first test of the Model s automatic rain wipers. Really quite useful, rainfall intervals it will work:
On the way into stuxnet, encountered an increasing number of Tesla owners left front has been able to see red-roofed factory:
Super factory still under construction:
Opening ceremony room appeared to be makeshift, but Elon said the location will be in the future a complete version of the Super Center of factory area:
Overcrowding, although writing holds up to 650 people at the door, but the exact scene of the guests there are 1500 people:
Chatting with the participation of owners, many people are from New York and Boston on the East Coast, there are many from Florida, and even Germany and Norway's owner, and the age span from teens to 79 years with:
Have wait in line to visit the factory, first listen to the message from Elon Musk:
This event live, so do not write duplicate content, individuals feel more interesting points:
1, Tesla will takeover Solarcity into the true meaning of power companies, covering energy production, storage and consumption all the links.
2, Gigafactory main production capacity for producing Powerpack and Powerwall, demand too much so to speed up the Gigafactory factory to build speed, Model 3 batteries to meet future needs.
3, China will build a factory.
Outside of manufacturing batteries, 4, Gigafactory, also has an important function is to recycle old batteries.
5, Tesla will automatically help you catch Pokemon (which is fun)
About Tesla Gigafactory
Followed by visit link, a dedicated bus headed to see:
Though went to Boeing in Seattle's aircraft manufacturing plant, but it was Tesla Gigafactory shocked by the scale of factories still Tesla logo in red and white color scheme:
Huge machines, robots and transport batteries:
Then go to the battery factory area:
Listen to explain Tesla's Entourage, Gigafactory 1 battery. Currently Gigafactory 1 10% production 95% Powerpack and Powerwall is the capacity do these two things, their purpose is far behind on orders, market demand is high even they are surprised.
Is also supporting the Elon leading Tesla to energy changes from a car dealer, so start a year early in order to meet the future Model 3 of the battery capacity.
On the difference between the two, they have specialized introduction:
Powerpack is aimed at business users, energy storage is 100kWh, Powerwall is the household, much less storage, the production version is 6.6kWh.
Both size comparison:
This is the Powerwall, video is this: YSL Galaxy S5 Case
Then it is installed in the wall look, quite a large one, but the design really nice:
This is Powerwall packaging:
This is the Powerpack, is much larger, and larger than a refrigerator:
This apparently is the Powerpack package (not sure):
Another point worth noting, Powerwall Powerpack and use a common set of core modules, is this the black battery pack:
Semi-finished products:
Robot was processing the battery pack:
And comparing this graph:
Can clearly see that the Powerpack is 15 in front that batteries are connected in parallel, speculated Powerwall, only one battery pack, it is not hard to figure out what such a storage battery is 6.6kWh, so just a Powerpack 15x6.6=99 kWh of capacity.
Maybe this explains why Tesla cancelled 10kWh Powerwall, parts commonality without 6.6kWh so good, after all, control.
Saying this modular design also brings the advantages of easy maintenance, like data center hard drive array, even broken a few hard drives can also be quickly replaced, instead of shutting down the whole system, I would like to parallel 7,000 Tesla electric car battery technology is ideal for them to do on this scale of products.
Batteries for transport robots in the factory:
Battery racks in the factory, now largely empty:
Finally, this is about to enter the Model 3 and Model S/X new 21-70 battery, will also be mass-produced here:
Visiting the battery factory outlet is the much anticipated Model 3:
210mi life (350km)
000 price
Automatic driver-assistance
Super charging network
Have to say, the real car is really nice, although this is close to the volume production of the vehicle:
Really love the panoramic sunroof, although I know very little.
Basically as long as the production date is delayed, and set off consumer enthusiasm for the Model 3 would be the first electric car.
Some thoughts:
About Tesla
Very lucky to be able to participate in the Gigafactory opening ceremonies, from the pics I took, as well as interact with the presence of the owner, I felt company Tesla CEO Elon Musk has a special affinity, make you feel this is held in the Palm of the user company. I personally participated in a lot of activities organised by the company, but Tesla this open gesture, invited the owners share the joy, did get a sense of participation and identity from the heart.
As compared, Apple not because you has "three pieces sets" and on you has any special care, but Tesla on old user of care and support can be described as meticulous: only Tesla old user invited to visit factory, through old user of invited links can let new buy car Shi save $1000,Model s from launched has fast 4 years, Tesla has been in for its for software update and provides new of function, also can not regularly get various invited participate in activities, These benefits just because you are their customers, you are their VIP, happily chose Model s.
About Elon Musk
In such a close distance for the first time to see "iron man," I am really very excited, like a biography describes as, participated in numerous speeches and public events, Elon is still under the spotlight with the shy child, he speak very fast, with a little bit of stuttering, sometimes able to focus of his statement, full of momentum. Was very kind and sometimes just like chatting with old friends, have no any shelves, let you automatically close. Elon has not many CEO kind of cunning, won't go around in circles to do Tai Chi dodged questions, most of the time he doesn't need to think about will be able to answer the core questions.
An interesting detail is that there are two bottles of water, JB Straubel has not touched, and Elon drank whole bottle of water. Elon on outspoken about Tesla and Gigafactory vision of solar, wind and other clean energy, batteries, electric vehicles, wheel, Model s for you to make money, just like Airbnb. Audience prompted cheers from time to time, this group of people from all corners, speak different languages, age span of three generations, but because of a common interest together, think is pretty exciting.
About Gigafactory
It's a huge factory, fully built scale is second only to Seattle's Boeing aircraft manufacturing factory. Interestingly Tesla's Entourage said the factory-equipment is Panasonic-sponsored, but Tesla assembled into finished products assets, so large a plant Tesla actually face, Panasonic is the real resources behind the Gold master. Such a factory is not only undertakes the manufacture batteries to increase battery density, aiming at reducing battery costs. Also the burden of old batteries for recycling and reuse tasks, Model s, Roadster, after all, have been available for years, battery will gradually decay, so recycling and reuse is better able to reduce pollution and save costs.
On the Model 3 YSL Galaxy S5 Case
More convinced after this visit the Model 3 would be an epoch-making product, competitors ' electric car could do nothing: mainstream the Leaf, i3, Bolt on the market a kind of pure electric vehicles, battery only 80mi/120km of standard Model 3 of the start is 210mi/350km.
And unlike electric cars may only be used for the city, Model 3 can road trip through the supercharger Super charging station, 40 minutes can be filled with the 80% battery.
Model 3 provides an automatic driving, if time, may also be seen to fully automated driving Model 3.
The key is, Model 3 design is very beautiful, so you have the desire to buy, competitor in the same price range of electric vehicles, hardly a square box shape is not strange, can't make out the design is black and electric vehicles or in promoting the industry.
On the Model s and a long road trip
On the Model s OTA (Over-the-Air Technology) system update, as a software engineer, software engineer who wants to take this case to say that Tesla team how tough.
The screenshot only shows part of the Tesla Model S/X has been released version 7.1 software update version number, detailed list please refer to the Tesla enthusiasts track Tesla software updates Web site: Tesla Firmware Upgrade Tracker.
I counted from January released the first 7.1 version has been updated to almost half a year now, Tesla official a total of 58 updated, is up to 8 updates a month, meaning that on average have two updates a week!
I want readers to consider Tesla's OTA update with the challenges to be faced:
Security--is the car's operating system, you must first guarantee security, if there is a security problem, then in the car may be deadly.
Stability – brush cell phones can allow black, brick, but this level of fault tolerance is 0, each time you update the stable must be guaranteed, how to deal with all kinds of accidents that can occur after a break or continue? Users don't want to upgrade in the Middle cars cannot use this to happen the next morning.
Compatible--Tesla Model of S,X population is currently around 130,000-150,000, 4 different models and configurations in different periods of time around 50-60.
New feature – on average, each version of Tesla is upgrading and providing new features, especially the major version update, such as 5.0, 6.0, 7.0, and so on.
Speed--quick-fix bug, optimize the system.
OTA release--push updates from the server to a different configuration, hardware in different years of the car.
All the software can control the six-point ask yourself: to all of the above challenges have to do with an average frequency of updating twice a week, how many companies can do that?
This open with based version 60 kWh of Model s from Bay District to Reno back and forth full 650 MI, is 1050km, whole journey basic as expected almost, driving 2.5 hours midway eat a lunch side charging, then continues to open, almost no special feel to with open gasoline car in time Shang difference, this also confirmed has I zhiqian for mileage and Super charging station of decision, said automatically auxiliary driving in highway travel Shi great of liberation has driver is I maximum of experience, Most traffic-can rest assured to the automatic driver-assistance to complete, even when this curve:
This is the road map for the journey:
The line above is going, the following line is back in the middle of the point is the super powered charging station.
Journey is a long journey in the photo below mileage record:
Can see this Model s battery consumption and lower than the EPA official claimed that the average power consumption (1mi consumes 300Wh), average energy consumption of personal 614.6mi just 278Wh, 8% less than the official nominal. So the official 210mi of battery life is true, at least in the case of the battery temperature is ideal in the summer.
PostScript
Just out of the 42-degree heat of the deserts of Nevada see the mountains, from the end of the world to paradise.
Yours and mine is only one Earth, hope our efforts can leave a blue sky for future generations.
This blessing Elon, Tesla and hundreds of thousands in order to allow us to advance into the era of clean renewable energy and efforts of people, you are truly changing the world Warrior.
