Compared to slightly closed dull car circles, the truss between Internet Technology Co., Ltd. is more active, and all kinds of big remarks, Jianghu Yi Wen is also more known.
Recently, Tencent executives on the public video platform “content like pig feed” on the open video platform of the open space, and triggered Tencent and bytes to jump between the two companies.
For a few months in the retirement, he extensively resonated the remarks, and the criticism of “Internet Black” in the 9th Anniversary of the Biography.
Zhang Yiming’s criticism, essentially a high-speed development of Internet big factories as a huge system, and the expression of internal employees, and some unity and alienation on the mind.
When we calm down, carefully review these “black words”, it is not difficult to find some of them “true demand”, and some are “pseudo concepts”.
Today, the electric state is to invent a few “black words” in the field of electricity and intelligent, and I hope that you can get some new inspiration from it.
■ From “Endurance Anxiety” to “1000km Breeding”
Even if it has been 2021, “Renewal Anxiety” is still a “ideological steel” .
At the new car conference of the vendor, the “Suspension of Suspend” in the PPT’s large life-fire mileage and leadership speeches have basically become standard.
In the media (of course, it also includes electric standard), the title plus “battery life XXX km!” Is a traffic password.
When buying a car, whether it is a young person who is used to surfing the Internet, orThe first time I contacted the oil car of the electric vehicle, I wouldn’t ask, “How is this car life?” 
Fuel car era, I believe most people will not be too much to run too much? Kilometer. How to become a magic curse that the electric car can’t get rid of the electric car?
The reason why the “original crime” that is not solid to end with early electric vehicles is not related to our cognitive habits.
Early technology is not mature, and more than a large number of immature electric vehicles have opened the road for a large number of immature electric vehicles for some manufacturers to push new cars for the national subsidies.
Subsequently, the problem of endless dummy, armpit, winter endurance, etc., became the pain of the seed owners of the crabs, and became the hotspots of the media reports.
For a long time, this “anxiety” is transmitted to the entire industry, and has become the “user pain point” that the manufacturer market personnel perceived, further evolving the topic of all new cars.
At the same time, each of us is more sensitive to the numbers when they are in contact information. As long as you simply search for “How to get a good title”, ten articles will tell you: multi-use numbers, write less text.
In this context, even if we understand that the urban commuter daily radius limit is only 200 kilometers, it is also known that the layout density of the charging pile is not the same, or will Eliminate the inertiality of the electric car life-fire mileage data.
So, in the beginning of 2021, the most popular keywords in the new energy vehicle turn became “1000 kilometers of life” – the battery life is done, and the battery is renewed in the winter, theoretically Beijing has opened to Shanghai, always not anxious? This will also have a lot of traffic in the manufacturer of Wei, Guangqi, and Zhisheng and other manufacturers.
Of course, no one will stand up and sing. The founder of Weima car suddenly stopped, indicating that after the charging pile layout is more perfect, after the fast charge technology is more mature, if the mainstream model is equipped with 1000 kilometers of battery life, it will form a huge waste of social resources. onlyCherish, the people in front of the mainstream public opinion are slight, but also questioned is intentional speculation, and the sales of Wema is not satisfactory.
How can the electric vehicle can take off the “battery life anxiety” hat? It may not be true that the battery pack energy is more, the larger the vehicle is more and more convenient, but the charging is more convenient, and the old NEDC battery life is accelerated. Various signs indicate that these are also a big trend in the industry.
He installed the charging pile at home, maintained three days of charging a frequency, and told me “Everyday taken from anxiety, even after changing the car, not considering the car”.
(The edited old emperor recently happened a car accident, repairing complement and re-on) 
■ Eighteen The soldier has a battery
“Renewal Anxiety” and “1000km Breeding” listened very flat, power battery related “black words” is already a five-flowers: “Blade battery”, “magazine battery”, “honeycomb battery”, “Jelly Battery”, “Solid State Battery”, etc., can make people feel “although not very clear, it seems to be very powerful.”
This has not yet finished. If you usually pay attention to battery technology, look at these nouns at first glance, you can also imagine their shape and look in my mind according to daily experience.
When the manufacturer puts a more hard core “three-yuan lithium battery”, “lithium iron phosphate battery”, “no cobalt battery”, “silicon supplementary lithium”, I am afraid it can only Samping a sentence: “I am going, what is the ghost?”
Let’s talk about the battery itself.
I believe that a battery is mentioned that the image that is first bullied in your mind is not a battery pack on the chassis of the electric vehicle, but below this thing.
In fact, the electric vehicle power battery is not so mysterious, basic principle, and the remote control in everyday life, the charging battery in the mobile phone is the same.
The Battery of Tesra model initially used is the battery supplied to laptop. Even if it is today, the “triple” of Tesla batteries has changed, but after being opened, it is still the picture below.
Briefly, the lithium ion battery consists of four parts: the positive electrode, the negative electrode, the electrolyte, and the separator. The process of charging the battery is to be an equivalent of the lithium ion carrying oriented to embed / desert between the positive and negative electrodes, and is known as the “rocker battery” in academic.
But seeing the above expression, I believe you are like me, “I know each word, but I don’t quite understand”
in order to let Everyone is more intuitively, we may wish to imagine the “battery” into a “swimming pool” that swims between the positive and negative poles:
charging, the lithium ion is holding electronic, from the positive electrode Turning to the negative electrode, and on the shore, sitting onto the small bench composed of carbon on the negative electrode.
Discharge, that is, lithium ions stand up from the negative “small bench”, jump into the electrolyte swimming pool, and retrans back to the positive, and put the electronic contained in his arms. 
We are not difficult to imagine that the more lithium ions in the pool, the more electronic, the greater the energy stored in the entire battery.
What determines the number of lithium ions? oftenAccording to the prescription, it is the positive pole of the battery. The common “lithium iron phosphate battery”, “three-dimensional lithium battery”, is the positive material.
“Lithium Lithium Lithium” is present in the form of lithium iron phosphate in nature, and the micro-orderly olivine structure is present.
Disadvantage is the limited lithium ion capable of “storage”, and there is a bottleneck in the energy density, and energy attenuation will occur under low temperature conditions. And since there is a “iron” in the name, the weight will be heavier.
“three yuan lithium” is not so “pure”, refers to the use of lithium-based positive electrode material using lithium nickel-cobalt-manganese acid or lithium nickellate acid Ion battery.
The three elements of each of the three elements: nickel elements and energy hooks, the higher the nickel content, the more electricity can be stored. However, its “character” is more “lively”, and two other elements need to support the structure and maintain safety. 
In addition, cobalt is still a rare element and the price is high. The main origin is in the Democratic Republic of the Congo. The problem of environmental pollution, miners, health, child labor, etc. caused by cobalt mines, also makes this rare metal mining have been accompanied by great humanitarian disputes.
The concept of “cobalt-free batteries” appears to be born, and many battery manufacturers are trying to find alternative elements instead of cobalt.
Although the “three yuan lithium” battery is not safe enough, it is more expensive, but based on the energy density, low temperature energy attenuation, light weight, and has become the current The choice of automakers can not be opened.
As for the “lithium iron phosphate” than “three yuan lithium” battery more “high-end”, only some manufacturers have misleading to the outside world during market publicity.
Talk to the positive material, let’s take a look at the other end of the battery: negative pole. This will lead another popular “black” in the beginning of this year – “Silicon-dosing”. 
The main material of the current power battery is graphite, which is carbon, which is also the reason why we have just met the other end of the pool as “graphite small bench”. The more these small beas are swung, and more lithium ions can be placed in, and the electricity of the entire battery can be improved.
Today, the graphite negative electrode material has also encountered a bottleneck, and these “small beas” reached the maximum amount. Thus, engineers aiming at the theoretical energy density than silicon materials having more than ten times higher than carbon.
However, silicon is a fatal injury as an electrode material, which is an expansion ratio. During the charge and discharge process, the volume of silicon will greatly expand shrinkage, think about it is not safe.
Therefore, in order to promote strengths, the battery manufacturer chose a compromise, incorporating nano-stage silicon materials in the carbon negative electrode to form a carbicon-negative electrode – mostly still “graphite small bench”, just added inside Some advanced “silicon sofas” that can sit in more lithium ions.
In addition to “silicon” in the negative pole, the engineers also thought of “lithium”: When the battery is charged for the first time, the lithium from the path from the positive direction, approximately 10%. Inverse loss. Then put a batch of “substitute players” first “arrange” in the negative electrode to make up for this part of the loss.
This technology is not unique to electric car batteries. Xiaomi 11 Ultra, which is listed this year, has been first used. I don’t know if the millet has been listed in the city after three years, the Lei Jun will not take this again to make a PPT. 
At this point, it is believed that the basic principles of the battery have been a preliminary understanding, which is the “illegal” of the power battery. “Blade Battery”, “Black Word” These “black words” is the “face” that automakers from the shape and structure of the battery will create “face” that makes the majority of consumers more easily identify and memorize.
Of course, these batteries launched by manufacturers in BYD, Guangzhou Automobile, have condensed thousands of engineers’ wisdom, and they have their own unique. Do notIn the original intention of R & D, everyone’s “initial heart” is consistent:
1. Under the battery volume, the energy density is as large as possible, support longer battery life. Take the “blade battery” as an example, although BYD has always purchased “no fire” and “safety” as the biggest purchase point, this is actually the innate advantage of lithium iron phosphate batteries. It is more difficult to enhance the battery power by breaking through the bottleneck of energy density by changing the physical structure.
2, safe. The fire is always the largest “magic” of the electric car, and the major manufacturers are also riveting in order to ensure safety. In addition to the hard work of the raw materials, it is still on the structure, temperature control system, and early warning system of the battery pack. The results of these innovations are the names of “magazines”, “honeycomb” and other tangible batteries.
If you think that the above schematic is not intuitive, then we have a class ratio in this life in this life.
A more imageive metaphor, everyone will follow another “black” – “Jelly Battery”.
■ The Finance of the Smart Electric Vehicle: “ACES” is a?
[123 ] The battery is used as a basic vehicle as a basic vehicle, and can bring us from a point to a point B point.
When talking about the battery, in addition to how much power is to support the battery life, everyone cares about the most basic security issues.
This is also the current electric vehicleThe intrinsic logic of big toys is questioned. After these most basic questions, where is the smart electric car really submerged?
I am afraid that it is often used by car manufacturers in recent years, “ACES, the new four” of automobiles “. 
“ACES” is a bit ancient. It was originally called the slogan shouting from traditional manufacturers such as BMW, Mercedes, and four words correspond to “Autonomous, Connected, Electric, Shared”.
Translated, is summarized by domestic manufacturers and media as “automobile new four”: automation, netization, electricity, sharing.
Of course, over time, the US tax software Uber foam is destroyed, and domestic drops become more and more like a super Internet taxi company, “sharing The concept of more and more people are mentioned.
The thief is like BMW, and the concept of “S” is changed to “Services Service” in its global strategy.
The industry trend has not changed. The “black words” mentioned above are the category of “electricization”. In addition to the most basic power changes, more subversive changes should be inside automation and interconnection, or more generally, intelligent. 
In the automation level, if you query the relevant concept, I believe it will be automatically driven by the L2 / L3 level, Tesla FSD, Xiaopeng NGP, Weima AVP these “black words” cloudy In the mist, I don’t know the cloud.
What is the meaning of L2 and L3 in automatic driving? Regarding this problem, the current standard is the grading standard specified by the SAE International Automotive Engineer Society. Let’s see the picture below.
The blue portion in the chart is an auxiliary driving, and the green portion is automatic driving.
However, everyone is the same, seeing this dense texture of the text, but the big premise is clear, when the automatic driving level of L3 and above, the driver can “sneak lazy”, no need .
and simply understandThe automatic driving of the Chu car company has a “black”, we may wish to look at the actual scene of daily driving.
When driving, everyone needs face-to-face scenes generally include closed roads such as highways, the daily driving of urban open roads and the most basic, but it is often always easier to go wrong. 
Under closed road conditions, the corresponding automatic driving function is currently included:
• Tesla NOA (NaviGate on AutoPilot pilot auxiliary driving);
• Navigate On Pilot, Pilot Driving);
• Recently, the new ideal one is promised to pay, will NOA open in September (like Tesla, ideal, even if it doesn’t want to spend a word to create a word).
The names of each manufacturer are different, but the function content is poor, that is, when driving into a highway such as a highway, set a end point, and the car can “fully automatically”. There, only need to take a certain degree of take over under complex conditions.
The parking is relatively complicated, and it is divided into fixed parking spaces and non-fixed parking spaces.
For the fixed parking space of the family and the company, the owner is required to drive the car “Demonstration” once, follow-up vehicles can follow the “learning” route, automatic parking. The HAVP and Xiaopeng P7 of Weimar W6 are about to upgrade the function.
More extreme cases, of course, in the mall, public parking lot, non-fixed parking space. Vehicles can automatically find parking spaces and park based on high-precision maps and artificial intelligence. Weima W6 follows up to the updated PAVP function, and claims to solve this scene.
Coping with more complex urban development road conditions, now except Tesla’s FSD (Full Self-Driving, fully automatic driving) and Huawei, no other manufacturers dare BoastBake ticket.
In this case, the vehicle is required to fully identify complex traffic factors such as traffic lights, pedestrians, and take-out little brothers to achieve “driver”.
Obviously, it is necessary to implement the above functions, to test the sensor, automatic driving software algorithm and chip of the vehicle.
The sensor is very well understood that the mm radar, ultrasonic radar and laser radar that have become “Nethong” belong to this category.
The former is represented by Tesra, and the software algorithm is under the software algorithm, claims to improve automatic driving ability through supercomputer independent learning, exercise algorithms.
The latter will lead to us familiar. I believe you still remember the satellites of the “1016 TOPS” overtinent platform when ET7 on the beginning of the year.
The “TOPS” herein refers to the processor’s calculation capabilities, and 1 TOPS represents one trillion times per second. The logic behind the 1016 TOPS is a bit similar to those who want to buy a computer and the parameters of the processor and graphics card: the stronger the calculation capacity, the stronger the computer performance, the more smooth the system, the better the image of the game that can run. 
This also allowed the ET7 just shown in the envelope, and he was called “invincible mine” by netizens. Combined with today’s global digital currency is hot, it is difficult to see the price of graphics cards, and there is so much truth.
■ Write in the last
Simplely understanding the above-mentioned more popular electric vehicles “black words”, I don’t know what you have view.
For the manufacturer, the purpose of these “black words”, in addition to popularizing new technologies, the more important purpose is to occupy the mind of consumers,Promote the train.
For everyone, it is still mentioned many times before, before buying a car, please ask yourself, what is the most authentic needs, what kind of electric car is needed.
