Lei Feng Network (search "Lei Feng Network" public concern) by: Author of this article Ryan Woo, once worked as an interaction designer at the Institute of Computing Technology, Chinese Academy of Sciences, and now as a computer software engineer in Silicon Valley.
On July 21, he suddenly received an invitation from Tesla and was fortunate to be invited to the opening ceremony of the Gigafactory Super Factory in Reno, Nevada, on July 29. Excited, I quickly booked a hotel in Reno and planned an itinerary. The first time I used the Model S to drive nearly 1,000 kilometers of mileage, what would be a different experience?
From the Bay Area to Reno in Nevada, 450 kilometers, as a basic version of 60kWh, the design mileage is 340 kilometers, so the charging must be in the middle, and there are nearly 10 supercharging stations along the way from the Bay Area to Reno. I chose halfway Roklin as a relay station, using Model S navigation, shows that there will be 20% of the remaining electricity when it arrives (in fact, this estimate is very conservative, after the actual arrival of 40% of the remaining electricity):
Due to the autopilot-assisted Autopilot experience, the entire high-speed trip was achieved by automatic assisted driving in addition to the upper and lower ramps. It still left a deep impression on me: whether it is a turn, a lane change, or an acceleration, Deceleration and follow are all excellent.
After waiting for the Rocklin Super Charging Station to power up, 8 charging piles were filled up. It seems that there are a lot of Tesla owners attending the event this time:
Waiting for a while to plug in the charging line, Rockside Super Charging Station next to a shopping plaza, after lunch just Tesla App prompts charging to complete.
The mobile phone shows 40 minutes rushing, charging power 98kw, it is pretty fast:
He continued to drive forward to Reno, a casino city in Nevada. Suddenly sudden changes occurred and thunder clouds appeared in front of him. Sure enough, he was exposed to thunder and rain at a distance of 10km from the factory, but it was just the first time that Model S was tested automatically. Rain wipers. It's really easy to use, depending on the amount of rain it will operate at intervals:
On the way to the Super Factory, there are more and more Tesla owners, and the red top factory has been seen from the left front:
Super factory still under construction:
The opening ceremony of the room seems to be a temporary build, and later Elon said that this location will be the center of the future full version of the super factory:
There was overcrowding inside. Although there were a maximum of 650 people written on the door, there were 1,500 guests actually present:
Chatting with the participating owners, many people came from New York and Boston on the East Coast. There were also many from Florida, and even German and Norwegian owners. They ranged in age from teens to 79 years old:
The factory is still waiting for the line-up to visit, first listen to Elon Musk's speech:
This release will have a live broadcast, so it will not write duplicate content, and personally find it more interesting:
1. Tesla wants to acquire Solarcity as a truly electric energy company, covering all aspects of energy production, storage and consumption.
2. At present, Gigafactory's main production capacity is used to produce Powerpack and Powerwall. The market demand is too large. Therefore, the construction speed of the Gigafactory factory must be accelerated to meet the future needs of the Model 3 battery.
3. China will build factories.
In addition to manufacturing batteries, Gigafactory also has an important function of recycling used batteries.
5, Tesla will automatically help you to catch Pokemon (this feeling is a joke)
Step into Tesla GigafactoryNext is the factory tour. There are special buses leading in to visit:
Although Boeing had previously seen the aircraft manufacturing facility in Seattle, it was still shocked by the scale of the Tesla Gigafactory. The interior of the factory is still the red and white color of the Tesla logo:
Large machinery, and robots that transport batteries:
Then go to the battery factory area:
Listening to Tesla's entourage, Gigafactory 1 only produces batteries. At present, only 10% of Gigafactory 1 is put into production. 95% of its production capacity is Powerwall and Powerpack. Their output is far from keeping up with orders. The market demand is so high that even they are surprised by their internals.
It is also a testament to Elon’s change in Tesla’s leadership from automakers to energy vendors, so the first year to start is also to meet future Model 3’s battery capacity.
Regarding the difference between the two, they have a special introduction:
Powerpack is aimed at industry users, and the energy storage is 100kWh, while Powerwall is a home appliance with much less energy storage. The production version is 6.6kWh.
The volume comparison between the two:
This is Powerwall, which is all in this video:
Then this is a wall-mounted look. It's pretty big, but the design is really good:
Here is Powerwall packaging:
This is a Powerpack, which is much bigger and bigger than a refrigerator:
This looks like a Powerpack package (uncertain):
It is worth noting that Powerwall and Powerpack use a common core battery pack, which is the following black battery pack:
Semi-finished products:
The robot is processing the battery pack:
Compare this figure again:
It can be clearly seen that the Powerpack is connected with 15 battery packs in parallel. It is assumed that there is only one battery pack in the Powerwall, so it is not difficult to infer that the storage capacity of one battery pack is 6.6 kWh, so 15x6.6 = 99 kWh A Powerpack's capacity.
This may explain why Tesla canceled the 10 kWh Powerwall, after all, the component versatility is not so well controlled by 6.6 kWh.
Saying that such a modular design will also bring the advantages of easy maintenance, just like the hard disk array in the data center. Even if several hard disks are broken, they can be quickly replaced instead of shutting down the entire system. I think Tesla The technical accumulation on the 7000 batteries in parallel with electric vehicles is very suitable for them to make such scale products.
Robots for transporting battery packs in the factory:
The shelves for the batteries in the factory are basically empty:
Finally, this is the new 21-70 battery that will enter the Model 3 and Model S/X, and will also be mass-produced here:
After visiting the battery factory, the exit is the Model 3 that many people look forward to:
215mi Life (350km)
000 from the price
Autopilot assists in driving the Supercharger supercharged network all over the world
It has to be said that the real car is really beautiful, although this is only a test vehicle that is close to mass production:
I really love this panoramic sunroof, although I know that the utility is very small.
Basically, as long as the production date is not delayed, the Model 3 will be the first electric car to detonate consumer enthusiasm.
Some thoughts: 
About Tesla
I was very fortunate to be able to participate in this Gigafactory opening ceremony. From what I saw and how I interacted with the car owners present, I felt that Tesla and its CEO Elon Musk had a special affinity. It was a sincere feeling that it was a user’s palm. s company. I personally participated in many company-organized events, but Tesla’s open-minded attitude inviting car owners to share joy is indeed a kind of heartfelt participation and recognition.
In contrast, Apple will not have any special care for you because you have a "triple set", but Tesla's care and support for the old user can be described as meticulous: only Tesla old users can visit the factory, and the old user's invitation link can Save $1000 when new people buy a car. Model S is four years from its launch. Tesla has been updating software and providing new features. It can also get various invitations to attend events from time to time. The above benefits are only because you are Their old customers, you are their VIP, fortunately chose Model S.
About Elon Musk
The first time I met “Iron Man†at such a close distance, I was really excited. Like the biography, although I participated in countless speeches and public events, Elon under the spotlight still had the guilt of the children. From time to time, speaking quickly, with a bit of stuttering, and sometimes he is able to reach the focus, full of momentum. Sometimes the attitude is very gentle, just like chatting with old friends and there is no shelf, let you unconsciously close. Elon doesn't have a lot of CEOs, he doesn't go around Taiji to avoid problems, and many times he can answer questions without thinking.
An interesting detail is that there were two bottles of water on the stage, JB Straubel did not stick, and Elon drank the whole bottle of water. The Elon on the stage chatted with Tesla and Gigafactory's vision, solar energy, wind power and other clean energy, batteries, electric cars, and automatic driving, allowing Model S to automatically make money for you, just like Airbnb. The audience cheered from time to time. This group of people from all over the world spoke different languages ​​and spanned three generations. But because of a common hobby, it was quite exciting to think about it.
About Gigafactory
This is really a huge factory. The scale after completion will be Boeing's aircraft manufacturing plant after Seattle. Interestingly, Tesla's entourage said that almost all of the equipment in this factory is purchased by Panasonic, but the finished product is Tesla's asset. So a huge factory, Tesla is only a face, Panasonic is really behind the money. Investor. Such a factory not only undertakes the purpose of manufacturing batteries, increasing the density of batteries, and reducing the cost of batteries. It is also responsible for the task of recycling old batteries and reusing them. After all, the Model S and Roadster have been on the market for several years, and the batteries will gradually attenuate. Therefore, recycling and reuse can reduce pollution and save costs.
About Model 3
After this visit, I am more convinced that the Model 3 will be an epoch-making product. There is basically no way for a competitor's electric car: the mainstream Leaf, i3, and Bolt are pure electric vehicles on the market, and the life is only 80mi/120km. Model The start of 3 is 210mi/350km.
At the same time, unlike the electric cars that can only be used in cities, the Model 3 can travel on the road via a supercharger supercharger station. It can fill 80% of the battery in 40 minutes.
Then Model 3 can provide automatic assistance driving, if the time is up, you may also be able to see Model 3 fully automatic driving.
The key is that the Model 3 design is very beautiful, so you have the desire to buy, the electric car with the same price of the competition, almost no one is not a strange square box shape, really do not understand these designs are black electric cars or to promote this industry.
About Model S and Long-distance Highway Travel
About the Model S OTA (Over-the-Air Technology) system update, as a software engineer, I would like to use this example to talk about Tesla's software engineer team how powerful.
This screenshot shows just a few of the currently updated versions of the Tesla Model S/X 7.1 software update. For a detailed list, refer to the Tesla Firmware Upgrade Tracker, a Tesla Firmware Tracker .
I counted and released the first 7.1 version update from January to now for almost half a year. Tesla released a total of 58 updates. It counts as 8 updates a month, which means that there are 2 updates a week on average!
I think readers and friends would like to consider the challenges faced by Tesla's OTA update:
Security - This is the car's operating system. It must be safeguarded first. If there is a safety problem, then it may kill people on the car.
Stability - Brushing the phone can allow black screens and tiles, but the car's tolerance for this failure is 0. It must be ensured that each update is stable, and how to deal with various possible accidents or continue after interruption? Users do not want the car to fail to use this situation the next morning after the upgrade.
Compatible - Tesla's current Model S, X's inventory is from 130,000 to 150,000, and there are about 50 to 60 different models and configurations for different periods of four years.
New features - Each version of Tesla will be upgraded and provide new features, especially large version updates, such as 5.0, 6.0, 7.0 and so on.
Speed - quickly fix bugs and optimize the system.
OTA release - Push updates from the server to each car with different configurations and hardware of different generations.
Everyone who makes software can ask themselves about these six points: To meet all the challenges above, but also to achieve an average of twice a week update frequency, how many companies can do?
This time, the basic version of the 60 kWh Model S went from the Bay Area to Reno for a total distance of 650 mi, which is 1050 km. The whole journey was basically as expected. It took two and a half hours to charge while having lunch and then continued to drive. There was almost no In particular, the difference between the time and the petrol car is evident. This also confirms my previous decision on the mileage and the super charging station. It is my biggest experience that the auto-assist driver has greatly liberated the driver during the road trip. Some sections of the road can be safely handed over to the car to assist in driving, even when including such corners:
Here is the road map for the entire journey:
The upper line is the journey, the lower line is the return journey, and the middle point is the powered super charging station.
The journey A in the photo below is the mileage record for this long journey:
It can be seen that the battery consumption of the Model S is even lower than the average energy consumption claimed by the EPA (1mi consumes 300Wh). The average energy consumption of the individual 614.6mi is only 278Wh, which is 8% less than the official standard. Therefore, the official 210mi life is true, at least in the summer when the battery temperature control is more ideal.
postscriptJust out of the hot desert at 42 degrees in Nevada, you can see the green mountains and rivers, and there is a feeling from the end of the world to earthly wonderland.
There is only one earth belonging to you and I. I hope our efforts today can leave a blue sky for future generations.
In this blessing of Elon, Tesla, and millions of people who are trying hard to advance into the era of clean renewable energy, you are the real warriors who change the world.
