Does BYD Han ev need to install chassis guard?

https://car3.autoimg.cn/cardfs/product/g31/M07/6A/89/800x600_0_autohomecar__autohomecar__ChtlyGXbLcqABwXdACoSzzdZfRU197.jpg

BYD Han EV is an electric car, so it doesn’t need chassis guard.

Chassis guard is a device used to protect the bottom of the vehicle, and the battery pack of electric vehicles is usually located at the bottom of the vehicle, so installing chassis guard may cause damage to the battery pack.

In addition, the chassis guard will also affect the aerodynamic design of the vehicle and reduce the cruising range of the vehicle. Therefore, it is not recommended to install chassis guards.

For BYD Han EV owners, in order to protect the battery pack, you can choose to install a battery guard. The battery guard can completely surround the battery, reducing the risk of battery bumping.

However, it should be noted that the installation of battery guard may affect the heat dissipation effect of the battery, thus affecting the performance and cruising range of the vehicle.

Therefore, before installing the battery guard, it is recommended to consult the advice of professional technicians.

From mobile phones to rims, Xiaomi and Huawei love each other.

Executives "talk to each other" at the car launch conference, or it will become a normal state of the industry.

Not long ago, Huawei held the HarmonyOS Ecological Spring Communication Meeting and released a number of new products. At the press conference, Yu Chengdong, managing director of Huawei, BG CEO, chairman of BU, Huawei’s smart car solution, and Yin Tongyue, chairman of Chery Automobile, released the first smart car, Zhijie S7, for the second time.

It is understood that the newly released Zhijie S7 has launched five models, among which S7 Ultra has been added as a high-end model. The official guide price is 249,800 to 349,800 yuan, and the price range is consistent with the old model.

Standing on the level of public opinion, the public doesn’t seem to be interested in the product itself, but what really makes people relish is Yu Chengdong’s series of remarks on "targeting" Xiaomi.

From the mobile phone stand to intelligent driving, Yu Chengdong’s "insinuation" of Xiaomi is familiar, just like the "routine" of the two companies at the mobile phone conference for many years.

However, the trend of executives of the two companies "talking to each other" from a distance has blown to a new battlefield this time, and the "grudges and enmities" between the two companies over the years will also stage a new story in the automobile market.

Yu Chengdong has never been soft on "friends". In this release, Yu Chengdong made many statements all the time, which can be said to be "tit for tat" with Xiaomi.

At the previous Xiaomi SU7 conference, Lei Jun once said: "I found that all the car manufacturers did not consider how to install the mobile phone bracket, and none of them worked well. We must make the best mobile phone bracket!"

At the S7 conference of Zhijie, Yu Chengdong said in a meaningful way: "I really don’t understand why many cars use mobile phone stands. Later, I understood that their car navigation performance is not good! We will let the mobile phone application get on the bus in full, and the powerful heart does not need a mobile phone bracket! "

In addition, Yu Chengdong also intentionally emphasized that the utilization rate of car navigation in HarmonyOS is as high as 99%, while the utilization rate of other car navigation is only 31%, and the gap is "very large".

Regarding Yu Chengdong’s remarks, Lei Jun issued a document in Weibo, saying: "At their press conference, General Manager Huawei ridiculed the design of our original mobile phone bracket for Xiaomi SU7." At the same time, Lei Jun also asked questions and initiated a vote: Do you support the original mobile phone bracket in the car? Why do you think we made the original mobile phone stand?

Up to now, 271,000 people have voted for this activity, of which 231,000 support the original mobile phone stand of Xiaomi SU7 and 40,000 do not. Zinc Finance noticed that the highest praise message in the comment area of the event was: "I can do without it, but you can’t do without it."

In addition to the episode of mobile phone stand, Yu Chengdong also made a targeted "insinuation" on intelligent driving.

It is reported that Lei Jun once said: "The whole industry is in the city of NOA. We started user testing in April, officially opened ten cities in May, and opened nationwide in August!" At the press conference, Yu Chengdong said: "Huawei Smart Drive is a spot, not a futures, and it is the best spot!" In this regard, Lei Jun did not send a response.

At the press conference, we conducted parameter benchmarking and technical comparison, or emphasized the strength of functions, and then the senior management published a document on Weibo to "communicate with each other" from a distance. This marketing technique and rhythm has become commonplace in the mobile phone circle, especially Huawei and Xiaomi, who have used this routine perfectly.

However, this has become a "new thing" in the automobile circle. After all, no car company has conducted such a "blatant" benchmarking before, and there has been no precedent for executives to speak out about competitors’ weaknesses at the press conference.

Obviously, with the competitiveness of Huawei and Xiaomi in the automobile market becoming more and more prominent, the two companies that have been "loving each other and killing each other" for many years have reached the time of "short-term intersection", but this time the battlefield has changed from mobile phones to cars.

In fact, the relationship between Huawei and Xiaomi in the early days was not "tense" at all, and even very "harmonious".

In 2012, Yu Chengdong sent Weibo that he needed to learn Internet marketing from Lei Jun, and Lei Jun also responded that Huawei has always been an example for Xiaomi to learn. At that time, the relationship between the two families was very harmonious.

In 2013, Xiaomi gradually gained momentum and launched Redmi, and Huawei also announced its glory independence.

In terms of brand positioning, Redmi, like Glory, focuses on products with a thousand yuan level. Including the product level, Glory 3C, the first mobile phone after glory independence, is very similar in appearance and configuration to Redmi. Later, sales proved that the two companies’ choices were undoubtedly correct. In 2014, the shipments of Glory and Redmi rose sharply, which brought more revenue to the parent company.

Even if they all made achievements, they all became the best in the market. At that time, the atmosphere between Xiaomi and Huawei was still very relaxed.

When the time came to 2015, Huawei began to make full efforts in the mid-to-high-end market, and achieved outstanding results, and the Mate series emerged. However, in the same year, Xiaomi, due to the insufficient supply of Xiaolong processors, led to a crisis in brand reputation and sales began to decline.

On the other side of Xiaomi’s constant problems, Glory seized this opportunity, eating away a lot of market share originally belonging to Xiaomi and Redmi, and helped Huawei win the first sales volume that year.

There is no doubt that 2015 is a watershed in the relationship between the two companies, laying the groundwork for the future "mutual tearing" between the two companies.

Only a few years later, Huawei Xiaomi began real competition, and the executives of the two companies frequently exchanged ideas at their respective product launches.

For example, in May 2018, HONOR officially announced that it will release Glory play on June 6, which will launch Huawei’s "very scary technology." Xiaomi immediately said that "Xiaomi 8 has many very scary technologies". In this regard, Huawei directly responded that it has a lot of technology. "Do you want to learn? It’s very difficult, so you should study hard. "

By the end of 2019, Xiaomi and Glory started a war of words for a week, starting with Xiaomi’s public relations Pan Da’s announcement that Weibo publicly questioned the existence of false propaganda on the glory smart screen.

In the next few years, such incidents were frequently staged. Even in the last year or two, the "DISS Friends" session at the two press conferences was never absent.

However, from a historical perspective, the reason for the "frequent tearing" between the two companies is also inseparable from the changes in the market environment.

In the years when the two companies were "in love", Samsung and Apple occupied most of the market share. At that time, domestic mobile phones needed to unite and reduce internal friction because of insufficient technical strength. But by 18 years or so, Samsung Apple has begun to decline, while the domestic mobile phone under the rapid development is rising step by step.

Without the threat of foreign enemies, domestic mobile phone manufacturers have also started a new round of competition, and the story of Huawei and Xiaomi "killing each other" has begun.

In fact, in the fact that the entire mobile phone market is gradually sluggish, the "gunpowder smell" of the two companies in the past two years is far less strong than before. But who would have thought that as both companies entered the new energy vehicle market, those familiar "old plots" turned back.

In 2021, after Huawei officially started its automobile business, it always claimed that it would not build cars, but only help car companies build good cars.

So far, Huawei has really not violated this creed, but with the increasing "Chinese content" of the entire automobile circle, consumers have been unable to tell who is the "protagonist".

Up to now, Huawei has reached cooperation with many domestic car companies, such as "Wen Jie" with Selis, Aouita with Chang ‘an, Zhijie with Chery, Polar Fox with BAIC and so on.

Although there are many cooperations, Huawei’s cooperative brands are only "out of bounds", and others are not excellent. As the first smart car that it cooperates with Chery, Huawei’s expectation for the intelligent S7 is obviously higher than other brands. Not only is it equipped with Huawei’s best autonomous driving technology, but it has also gained an unprecedented "momentum" from Huawei.

Unfortunately, judging from the current results, the performance of the intellectual community is very unsatisfactory.

Zhijie S7 has been on the market for nearly five months, and its sales in these five months have failed to exceed 1,000 vehicles. Specifically, there were 115 and 784 vehicles in November and December last year, and 604 and 794 vehicles in January and February this year, respectively.

In the same price segment, on the other hand, Xiaomi SU7 stole the limelight after listing, and the heat continued to rise, and the sales volume was even more popular.

According to public data, Xiaomi Automobile delivered a total of 1,093 vehicles in the 14th week of 2024, ranking 9th among new energy automobile brands. In addition, in the brand sales ranking of the pure electric vehicle market of more than 200,000, Xiaomi Auto also successfully entered the list, ranking fifth with sales of 1.1 thousand vehicles, surpassing Zhijie and Xpeng Motors.

It is worth noting that the delivery of Xiaomi Auto started on April 3rd, and the 4th to 6th falls on Tomb-Sweeping Day holiday, so this data can not fully reflect the actual delivery potential of Xiaomi SU7.

The sales volume of Zhijie S7 can’t exceed 1,000 in five months, and the sales volume of Xiaomi SU7 will exceed 1,000 in the listing week.

Under such a "gap", Huawei can’t turn a blind eye. It must readjust its propaganda caliber and regard Xiaomi as its core competitor. This is also the reason why Huawei wants to "second" release the intelligent S7.

Huawei should re-emphasize the technical gap between Zhijie S7 and Xiaomi SU7, so as to gain more consumers’ recognition and increase sales.

After 2018, the "mutual tearing" between the two companies can be seen as a microcosm of the marketing war of mobile phone brands. Now, this process will be repeated in the automobile market.

So, who will be the ultimate "winner"? This question is not important. It is important to hope that Huawei and Xiaomi can benefit consumers with better technology under this kind of competition, so that the whole new energy automobile industry can reach a higher level.

Xiaomi car finally arrived, and I was moved by its face value.

Original neck brother bad review

This year’s most popular tram (one) is coming!

At about 4 pm on November 15th, Xiaomi Automobile appeared in the announcement of the Ministry of Industry and Information Technology, and related topics immediately rushed to Weibo for hot search.

Colleagues in the editorial department also gathered around and looked at several existing bulletin boards on the website for at least half an hour.

I have to say that the appearance of the rice cart is not poked, but it grows in the aesthetics of most people. It belongs to 10 people, and 9 people will praise it as good-looking.

From the picture below, the body proportion of Xiaomi car is relatively slender, which gives me the first impression that it is not like an electric car, but closer to an oil car.

The posture is very online, the small wide body at the back is very right, and the whole slip back looks elegant from this angle.

Moreover, you can even find the logo of "Founder Edition" in the optional equipment. What is the user perception? . .

It’s the logo with the letter xiaomi in the back. I always feel that there are a little too many words. . . So that the oil head designer really couldn’t stand it, simply "cut off" the logo and blackened the decorative parts below.

Look at the picture, isn’t it much more pleasing to the eye?

Anyway, after reading the car, some colleagues in the editorial department said it looked like Martin’s and some like Porsche’s, but they all came to the same conclusion that it looked good.

Incidentally, the guy who said he looked like Porsche soon claimed to have found "strong evidence" in Lei Jun’s Weibo. . .

However, it is said that the overall design of Xiaomi car is still self-contained. A closer look shows that this car is not only attractive in appearance, but also in the direction of performance in various designs.

Looking at it from a 45-degree angle, this yellow Brembo caliper is very conspicuous. Tires are also tough guys. Michelin’s PS EV is used for the high-end tires, and the rear tires are 265mm wide. At the same time, there is an air guide slot in the front and rear wheel arches, which can dissipate heat for the brake discs.

Moreover, according to the gossip, this cooling duct is real, and I won’t laugh with you.

Not only that, its rearview mirror even has an optional version of carbon fiber, which can be lighter, and the visual horsepower can be increased by at least 5 horses.

In addition, there is an active tail with adjustable angle at the back. Although there are a lot of these things in domestic cars now, before they were put, they were all things that AMG only had, and at worst they had to be Audi TT.

Regardless of how effective it is, at least it looks like a fight.

In addition, Brother Neck brushed a photo of the interior of a suspected millet car in the group today. Look at these two round knobs. I haven’t pressed them yet, and I’m already driving a rice car to New North in YY.

After the appearance, let’s take a look at the most basic parameters.

First of all, what I didn’t expect was that Xiaomi built a C-class car.

This car is named "SU7", and its length is 5 meters, to be exact, it is 4997mm, which is longer than those cars such as Tesla Model 3 and Weilai ET5, and is similar to BYD Han.

Originally, I guessed that it would be around 4.8 meters, because the size of A+ or B-class cars is more in line with the positioning of "the first car for young people". But they took out a C-class car at once, and the price may not be cheap. . .

In terms of configuration, SU7 has at least three versions: normal version, Pro, Max, and these versions should be distinguished in Sandian, Lidar and performance suite.

In addition to the performance suite we talked about in the appearance, the Xiaomi part of Sandian has also made some differences.

According to the announcement, the total power of the high-profile dual motors is 495kW (front 220kW, rear 275kW), which is a little higher than the 486kW of Tesla Model 3 Performance. As a sporty car, this horsepower is definitely enough.

The supplier of motor is Huichuan, and it is also an old-fashioned supplier of motor and electric control in China. Its home supplies ideal, Chang ‘an, Great Wall and other car companies.

And the battery is lithium ternary from Contemporary Amperex Technology Co., Limited.

The low version is a single motor with a power of 220kW, and the supplier is United Electronics. The battery is made by BYD, Ferrous lithium phosphate.

It is a routine operation to make a difference in battery capacity and motor power. However, there is also a speculation on the Internet that the high-voltage platform is equipped with 800V and the low-voltage platform is 400V, which can pull down the price of the entry version.

I think it’s better to cut some other configurations than using 400V platform on the low-end configuration, because 800V can obviously improve the charging speed, which is a configuration with obvious user perception.

The models released this year, such as Tucki G6 and Zhijie S7, are all equipped with 800V as standard. If Xiaomi doesn’t keep up next year, it’s somewhat unreasonable.

Then there is the lidar. Like friends and businessmen, Xiaomi is placed in the middle of the head and can be seen at a glance.

This configuration is basically differentiated in intelligent driving. For example, in an ideal model, those with lidar will have NOA function in the city, while those without lidar can only drive NOA on the highway.

However, unlike other companies, Xiaomi’s lidar can’t see the plane scanned by laser on the outer surface.

You see, all other models look like this, and the outline of a rectangle in front is very obvious.

Xiaomi’s does not have this outline, and the whole is smaller and more rounded, which is relatively less abrupt. The obvious advantage is that the wind resistance is lower, and there is likely to be some black technology here.

The information known about the rice car at present is probably the above. After the announcement of this car, in addition to the boiling of netizens, it also triggered the enthusiastic attention of some track and performance car owners.

To tell the truth, as a car editor, I really like their sports orientation. But, the category of performance cars is doomed to have little market.

In the words of colleagues, "everyone is talking about it, who really buys a performance car?"

If you want to sell the car in quantity, you must have some household use.

However, as a C-class car, it has a lot of advantages in the interior space, and the gossip says that the interior space of this car is large enough to sit casually in the front row and back row. I don’t know how Xiaomi can use the interior space to impress consumers under the label of "performance".

There is another interesting thing about Xiaomi’s car-making qualification. At least from the announcement, this time there is an answer for the time being.

The enterprise applying for Xiaomi Automobile this time is Beijing Automobile Group Off-road Vehicle Co., Ltd., which is a subsidiary of BAIC Group.

But let’s look at the production address of the car, not the location of BAIC, but Xiaomi’s own new car factory in Yizhuang.

Before August, it was reported that Xiaomi had obtained the qualification of the National Development and Reform Commission, but he had to go to the Ministry of Industry and Information Technology to get the qualification.

In other words, up to now, Xiaomi has not fully obtained all the qualifications for making cars, so although the car was made by himself, it borrowed the qualifications of BAIC.

At the tail of Xiaomi car, it also says "Beijing Xiaomi", not "Xiaomi car".

According to today’s report by Cailian, Xiaomi should continue to apply for car-making qualification.

From the point of view of qualification, I guess Xiaomi Automobile may think that the qualification approval process is too long and the product can’t wait.

According to Xiaomi’s plan, they will release the first model in the first half of next year. But now the auto market has gone crazy, and the later you enter the market, the more passive you will be.

Take the market segment of C-class sedan targeted by Xiaomi as an example. Before that, there was BYD Han, which sold 20,000 yuan a month, and after that, there was Extreme Krypton 001, which was the main control. Just last week, Aouita 12 and Zhijie S7, which were blessed by Huawei, just went public, and these two also came to this range.

Especially in Zhijie S7, its size is completely the same as that of Xiaomi SU7, and both of them are from mobile phone factories. The car-machine interconnection and smart driving are also the main items.

Therefore, I estimate that in terms of function, configuration and pricing range, the rice car is likely to collide with the intellectual S7.

Therefore, Xiaomi is now rushing to the announcement of the Ministry of Industry and Information Technology, and feels that he is also speeding up himself. Don’t wait until others have divided up the market before bubbling.

In fact, from a long-term perspective, the progress of Xiaomi Automobile is actually not slow. Lei Jun announced to build a car in March 2021. Today, it takes about two and a half years.

When the Wei Xiaoli family built their first car, it was almost the same rhythm.

However, the time for Xiaomi to enter the car has been 7 years later than Wei Xiaoli’s new forces and 18 years later than Tesla. The intensity of market competition is not what it used to be.

However, Xiaomi’s first show today still gave everyone enough surprises. It’s just that there is very little information at present, and it’s hard for us to judge how high its combat effectiveness is.

According to the news that Brother Neck heard privately, Xiaomi has tricks in the motor, intelligent driving and cockpit. I’m not sure how tough it is, but it must be the first echelon in the cockpit, the car and the interconnection.

After all, it is obvious to all that mobile phone manufacturers are going to make car machines.

There is only one key question left. How much will the rice cart sell?

Judging from the current market situation, Brother Neck guessed that the high match of Xiaomi should not be too cheap, but it may be controlled at around 300,000. As for the number of low matches, it is hard to say, it may not exceed 250,000.

But we also know that Xiaomi usually gives a very cost-effective price, especially the first generation products, and there may be a buff bonus.

Looking at the fun fitness method, morning exercise is on the rise, and crawling fitness is popular in Britain.

  August 8 every year is China’s "National Fitness Day". Many people feel hot and tired when they think about fitness, and it is difficult to persist for a long time. In fact, there are many ways to keep fit. You can choose the happy one! Let’s take a look at some novel and interesting happy fitness methods that people all over the world have.

  Crawling exercise

  There are various ways to do morning exercises now, but recently a new exercise method has quietly emerged, that is, "crawling". Crawling fitness originated from Hua Tuo’s "Five Birds Play", which is to achieve the purpose of fitness by imitating the crawling movements of animals. Crawling can disperse the whole body weight to the limbs to reduce the load of all parts of the body, especially the lumbar spine, so it has certain curative effect on preventing and treating lumbar spondylosis, lumbar muscle strain and spinal diseases. In addition, crawling is a whole-body coordinated activity, which can make some muscles that are rarely used at ordinary times get exercise and strengthen the muscles, ligaments and bones of the whole body.

  body building exercise

  It is also a good choice to do a set of aerobics with soft music by taking advantage of the fragmented time in life. Mary Helen Bowers used to be an actress in the New York City Ballet. However, after ten years of dancing, her body was completely deformed due to her unrestrained life. Later, she used the previous ballet routine to create "Ballet Beautiful Ballet", a family-style exercise for women, and the "Swan Arm" course, which recently became popular in the domestic network, was one of them.

  Ballet dancing can achieve the effect of exquisite shaping. Every tiny muscle from finger to toe will be used when doing the action, even if it is a small action, it will have great sports effect. The point is that long-term practice will make people exude elegant and light temperament from the inside out.

  Running on the sand was once a very popular exercise method in Britain, which originated from running on the beach. Because running at the seaside is limited by many factors such as time, place, weather, etc., people move the beach indoors, so there is a sand house dedicated to running and exercising in London.

  Running on the sand is good for your health. First of all, when running on the sand, in order to keep the body balanced, the leg muscles should work harder than usual, which can enhance the exercise effect on the muscles; Secondly, the joints of ankle, knee, hip and waist should cooperate with each other to improve joint flexibility and enhance cardiopulmonary function; At the same time, fine sand can massage the soles of feet, improve peripheral blood circulation, improve resistance and cold tolerance, stimulate accessory adrenal tissue, promote hormone secretion, and whiten skin!

  parkour

  Parkour created by the famous French actor david belle is very popular all over the world. This sport takes the daily living environment (mostly cities) as the sports venue, and it is a sports art that relies on its own physical strength to quickly, effectively and reliably control any known and unknown environment. At the same time, it is also a philosophy to explore human potential and stimulate the limits of body and mind.

  Parkour can strengthen physical fitness and improve reaction ability. A professional parkour trainer can correctly control the danger and minimize it. When he is caught in various dangers such as fire, earthquake, attack, car accident and emergency, his chance of escape will be more than 20 times higher than that of ordinary people.

  recite

  In Japan, poetry reading is regarded as an activity that is both healthy and healthy. Japanese health experts believe that reading poems aloud often can increase vital capacity, improve memory, make thinking more flexible and clear-headed.

  Kick a fireball

  Young football fans in Indonesia like to play a special "playing fireball" sport. The sport is similar to playing football, except that the ball they use is burning coconut. What is even more surprising is that they all kick these hot fireballs barefoot.

  It is reported that this activity of kicking and burning coconuts barefoot is closely related to a traditional fighting skill in Indonesia. The purpose of holding this activity is to improve the courage of the participants while keeping fit.

  Kneeling fitness method

  Kneeling fitness method is a popular fitness method at present, which is created by urban white-collar workers. Although this method looks "shocking" at first, some doctors say that kneeling after meals can draw blood downward, which is beneficial to digestion and weight loss. However, kneeling fitness also varies from person to person, and it is easy to oppress the nerves of lower limbs for too long, so you can persist for more than ten minutes after meals.
