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.

What is the change in the countdown market when the illegal "old scooter" is banned?

  Countdown to the violation of the "old scooter"

  Some merchants use the "new national standard" and "playing cards" to fool people.

  Electric tricycle is often called "old scooter". Recently, the news that the illegal "old scooter" will not be allowed to drive on the road or park in public places next year has attracted special attention. This incident originated from the Notice on Strengthening the Management of Illegal Electric Three-and Four-Wheelers jointly issued by various departments in 2021, which stipulated that a three-year transition period should be set for illegal electric three-and four-wheelers purchased before the promulgation of the Notice. On January 1, 2024, after the expiration of the transition period, law enforcement departments will strictly investigate and deal with relevant vehicles that violate the rules.

  The illegal "old scooter" is forbidden to stop and enter the countdown. What changes have taken place in the market? The reporter’s unannounced visit found that the sales of electric three-and four-wheeled vehicles have been very hot recently. Take the fully encapsulated new car as an example, the price generally exceeds 10,000 yuan, and the "agency fee" of about 2,000 yuan will be added to buy a new car. The reason why these cars are expensive is that they are all "new national standard" cars, which are legal vehicles and will not be checked on the road. In this regard, some citizens are very confused. In the 12345 hotline, the number of inquiries about the purchase of electric tricycles and driving on the road has also surged recently. Can an electric tricycle be bought now? Are all the "new GB" cars really legal vehicles? On the issues of public concern, the reporter asked the traffic control department for verification.

  On Xinhua South Road in Tongzhou District, various types of electric tricycles are for sale by the roadside.

  There are many electric tricycles parked on Xincheng South Street in Tongzhou District, and most of them have already hung the "Jing B" number plate.

  find

  More and more old people use the "Jing B" number plate.

  On the afternoon of April 11th, the reporter passed by the road around wanda plaza, Tongzhou District, just in time for the children to leave school. All kinds of electric three-and four-wheeled vehicles kept passing by, and many vehicles were very similar in appearance to motor vehicles, with notes such as "for personal use" and "picking up children" posted on the windows. Through the window, it is not difficult to find that the drivers of vehicles are mainly elderly people. The reporter also found that the location of these vehicles’ hanging number plates has changed from the factory billboards or auspicious figures in the past to the "Jing B" number plate of motorcycles today.

  In front of a primary school, while parents were waiting for their children to leave school, the reporter interviewed a number of electric tricycle owners. Tian Laobo’s car is hung with the "Jing B" number plate. This car was recently bought by him, and it cost 16,000 yuan, and another 1,500 yuan was spent on the card. "Very expensive!" The old man frowned as he spoke. He said that in order to pick up and drop off the children, it is a once-and-for-all way to spend more money on a car that the traffic police don’t check.

  The reporter asked how to "once and for all"? The old man explained that when buying a car, the merchant told him that the traffic control department strictly investigated the "old scooter", so that kind of car could not be sold or on the road. Now the store is not selling the old scooter, but a three-wheeled motorcycle. Whether it is charged or burned with oil, it is a motorcycle. If you buy this car, the traffic police will not check it again. "Said this car is normal, in a directory, belong to ‘ New national standard ’ , not affected by the three-year transition period, just run. "

  Under the guidance of many parents, the reporter came to Xinhua South Road nearby, and there are many electric car shops on the west side of the road. The electric tricycles to be sold occupy the sidewalk in front of the store, which is dazzling. Many customers who are ready to buy a car are listening to the merchants’ "interpretation" of the laws and regulations on car purchase and driving.

  Merchants said that according to the Notice on Strengthening the Management of Illegal Electric Three-and Four-Wheelers, by the end of this year, all "old scooters" can no longer be sold or on the road. The car they are selling now is licensed by the Ministry of Industry and Information Technology, but the car type is defined as a three-wheeled motorcycle, so it is necessary to get the "Beijing B" number plate. This kind of car can be bought with confidence and is not affected by the three-year transition period. "Because the vehicle has to enter the catalogue of the Ministry of Industry and Information Technology, it will cost a lot of money, so the car is expensive now. You spend thousands of dollars riding an illegal car, and it is thousands of dollars after being detained by the traffic police. It is better to buy a traffic police in one step and not check it. "

  Don’t you need to take a motor vehicle driver’s license to drive a motorcycle with "Jing B" number plate on the road? Faced with the reporter’s question, the merchant hesitated for a long time and replied that according to the current laws and regulations, only the "Beijing B" number plate is required for vehicles, and the driver is not required to hold a motor vehicle driver’s license. As for whether the traffic police will check it after the transition period expires, it has not yet been decided.

  Chaos

  All kinds of gimmicks make it difficult to tell the truth from the false.

  The reporter’s visit found that in many urban areas, merchants have different interpretations of the policies and regulations of electric three-wheeled vehicles. In addition to the "new national standard" that is strongly advocated, "licensing" has become a big gimmick.

  When visiting a number of electric car shops in West Building Materials City, Changping District, the merchants asked the reporter whether his ID card belonged to Changping District or Haidian District. The merchant explained that it is necessary to recognize the ID card to apply for the "Jing B" number plate now. The West Road of Building Materials City is at the junction of Changping District and Haidian District, but the rules for licensing in the two regions are different. If Changping District is shown on the ID card, the "Jing B" number plate can be handled directly, but if it is Haidian District, it is counted as within the six districts of the city and cannot be handled. "If you are from Haidian, we can do it for you and find a Gong Hu in the outer suburbs, but the handling fee will be more expensive, and you have to add 1,700 yuan."

  In the past week, the reporter made unannounced visits to a number of electric car dealers in many regions. The opinions of the merchants mainly focused on the following points: First, the "old scooter" will no longer be allowed to go on the road in the future, and the "new national standard" car is a three-wheeled motorcycle, which can replace the old scooter. Second, the "new national standard" car belongs to a motor vehicle, and it needs to be on the "Beijing B" number plate, which can be handled by itself or through "licensing". Third, drivers are not required to hold motor vehicle driving licenses, which are not within the scope of strict investigation by the traffic control department and are not affected by the three-year transition period.

  The reporter inquired about the relevant policies and found that these conclusions given by the merchants were full of doubts. While avoiding talking about many core requirements issued by the government, many laws and regulations were re-grafted out of context, and a large number of concepts were completely confused.

  Question 1

  Are all "old scooters" banned at the end of the year?

  Liu Jian, deputy squadron leader of the Motor Vehicle Management Squadron of the Vehicle Administration Office, told the reporter that the term "old scooter" is a concept hyped by businesses, which generally refers to electric three-and four-wheeled vehicles. There is no iterative or mutual elimination relationship between the two. In the "Notice on Strengthening the Management of Illegal Electric Three-and Four-Wheelers", the handling methods for the sale and riding of illegal electric three-and four-wheelers have been clarified. The merchant said, "All ‘ Elderly scooter ’ It is not accurate to say that you will not be allowed to go on the road in the future. There are compliance and non-compliance among electric three-and four-wheeled vehicles. Among them, when the compliant vehicles leave the factory, they should obtain the factory qualification certificate of the whole motor vehicle, and at the same time, they should be included in the Announcement of Road Motor Vehicle Manufacturers and Products, which is also referred to as the "Announcement Catalogue" for merchants. At present, there are more than 900 models and more than 170 brands of related vehicles involved. For compliant vehicles, there is no "new national standard", and the Announcement of Road Motor Vehicle Manufacturers and Products has always existed and is constantly updated.

  Hou Fei, chief of the Ping An Office, said that according to the requirements of the Notice on Strengthening the Management of Illegal Electric Three-and Four-Wheelers, from January 1 next year, illegal electric three-and four-wheelers will be completely banned from the road in Beijing. At this stage, for the management of these vehicles, the traffic control department mainly investigates drivers’ illegal driving behaviors such as running lights and retrograde. Now the compliant vehicles being sold by merchants are actually not unrestricted. The driving range allowed by compliant electric tricycles is outside the Sixth Ring Road in Beijing. In the Notice on Strengthening the Management of Three-wheeled Motorcycles and Disabled Wheelchairs issued in 2010, it is clearly stipulated that three-wheeled motorcycles are prohibited from driving on the roads within the Sixth Ring Road (inclusive) of this city. The so-called compliant electric four-wheeled vehicles are actually regarded as electric vehicles, and the relevant requirements refer to the relevant management measures for new energy vehicles.

  Question 2

  Just license the vehicle, don’t you need the driver’s license?

  "Just now we have talked about the difference between an electric tricycle and a four-wheeled vehicle." Liu Jian said that electric tricycles belong to three-wheeled motorcycles and need to be equipped with motorcycle number plates, while electric four-wheeled vehicles need to be equipped with special number plates for new energy vehicles since they are regarded as electric vehicles.

  "The need for a motor vehicle driver’s license has nothing to do with the transition period." Wen Wei, a policeman from the Optimization Section of the Order Department, told reporters that it is also wrong for merchants to say that they only need to be licensed without holding a motor vehicle driver’s license. As long as you are driving a motor vehicle on the road, the driver should hold the corresponding motor vehicle driver’s license. Even if you are riding an electric tricycle, driving without a motor vehicle driver’s license is also an unlicensed driving behavior.

  Question 3

  Why are businesses misleading consumers repeatedly prohibited?

  In the verification of the traffic control department, the reporter found that the driving requirements for electric three-wheeled vehicles also include many aspects, such as the requirements for drivers and their age, that is, those over 18 and under 60, and those over 70 need to downgrade their motor vehicle driving licenses. The purpose of all kinds of requirements is to protect the driving safety of drivers and maintain the traffic order in this city. However, why do businesses now dare to mislead consumers with laws and regulations?

  Under the surface, there are still many details worthy of further refinement by relevant departments. Previously, when this newspaper conducted a series of surveys on the scooter for the elderly, it was very common for businesses to sell electric three-and four-wheeled vehicles to the elderly without motor vehicle driving licenses. Compared with the process of buying a car, because the driver’s license information needs to be provided when shaking the number, the probability of the driver driving without a license after buying a car is greatly reduced. When buying an electric three-wheeled vehicle, who will supervise whether the car buyer has a driver’s license? In the process of vehicle inspection, it is not mandatory for me to be present or provide identification of the vehicle owner. From this point of view, there is still room for further improvement in many links in the whole process.

  Tips

  How to choose a compliant electric tricycle?

  Recently, the people who are very concerned about the purchase and riding regulations of electric three-wheeled vehicles are parents of students. Since April 14th, many parents have reported that some kindergartens and primary schools have started to count how many children go to and from school by electric tricycle. Many parents ask, when buying an electric tricycle, how can you know whether the car you bought is compliant or not?

  The traffic control department suggested that the Announcement of Road Motor Vehicle Manufacturers and Products is an important basis, and the brands and models of compliant vehicles can be compared with the relevant information in the official website of the Ministry of Industry and Information Technology. However, the reporter found that the information that can be found on the official website of the Ministry of Industry and Information Technology is displayed in batches, not a summary table. For example, at present, the 370th batch is being publicized. In the form, all kinds of vehicles are mixed together, and there are dozens of types such as motorcycles, wreckers and caravans. It is not convenient to find the corresponding batch and then pick out the corresponding vehicle type. Although there is a query function at the top of the form, it is necessary to provide all kinds of information such as enterprise name, product trademark, product name and product model, which is difficult for the elderly to query.

  After further verification with the traffic control department, in addition to referring to the Announcement of Road Motor Vehicle Manufacturers and Products, there is another simple way, that is, to check the ex-factory certificate of the vehicle from the seller during the car purchase process. This certificate of conformity is like the "identity card" of a compliant vehicle, and its content corresponds to the registration information of the vehicle in the Announcement of Road Motor Vehicle Manufacturers and Products.

  In addition to compliance with cars, people should also be "compliant". Electric tricycles belong to three-wheeled motorcycles, and motorcycles are divided into ordinary motorcycles and mopeds. To apply for ordinary motorcycle driving qualification, you need to meet the requirements of over 18 years old and under 60 years old, while to apply for moped driving qualification, you can be over 18 years old. If you are over 70 years old, you are not allowed to drive ordinary motorcycles, and you should be downgraded to moped, that is, "F".

  It should be noted that the difference between ordinary and mopeds is not judged only by the size and weight of the vehicle. According to the standard, motorcycles with a speed of more than 50 km/h, a displacement of more than 50cc and a total rated power of motors of more than 4 kW are recognized as ordinary motorcycles. In the process of buying a car, consumers can consult the merchants for detailed vehicle parameters.

  In addition, compliant electric four-wheeled vehicles are small and micro passenger vehicles, and the vehicle classification belongs to pure electric vehicles among new energy vehicles. The requirements for licensing, purchase and driving on the road refer to the relevant management measures for new energy vehicles.

The 48-hour three-time swimming world record genius Ziegler terrorizes the world.

    Titan sports News Ten months ahead of schedule, American female long-distance swimmer kate ziegler began to build momentum for her trip to the Beijing Olympic Games next year. On October 14th, in a short-course competition in Essen, Germany, Ziegler set a new world record for the 800m freestyle just two days ago-it was the third time in a row that she broke the world record within 48 hours!


    [Breaking records becomes a common practice]


    The 19-year-old Ziegler swam 8 minutes and 8 seconds in the 800-meter freestyle on the 14th, but in the 12th, she had already achieved 8 minutes and 9 seconds and 68 seconds in the first 800 meters of the 1,500-meter race, breaking the previous 800-meter world record of 8 minutes and 11 seconds held by French player Manudou. It took Ziegler only 15 minutes, 32.90 seconds to swim the whole 1500 meters, which also broke Manudu’s world record of 15 minutes, 42.39 seconds. This is the second time that she has broken the world record of 1500 meters in nearly 10 seconds! In June this year, Ziegler broke the world record of 15 minutes, 52.10 seconds set by Janet Evans, the greatest female swimmer in American history, in 15 minutes, 42.54 seconds, and shortened the record by 9.56 seconds at one time.


    Evans, who retired 10 years ago, was also amazed at Ziegler’s achievements. The latter once sincerely praised Ziegler when he broke his world record for the first time in June this year: "1500 meters has always been my favorite. Kate broke my record at the same age as I was. It was terrible. This record often advances by 1/100th of a second, so you have to admit that she is one of the greatest athletes in the 1500m event. "


    Kate ziegler was born in Virginia, USA on June 27th, 1988, and won the 800m and 1500m gold medals in two consecutive swimming world championships in 2005 and 2007. She is also the second female swimmer to swim 16 points in the 1500m after Evans.


    Ziegler is simply a swimmer born for records-he is good at freestyle from 200 meters to 1500 meters. Since he was 15 years old, he has set new American records one after another, including American records of all ages in long-distance events, many of which are on Evans’ shoulder. What is more representative is that in February 2005, she broke the national record of 800 meters, which had been silent for 25 years, in 8 minutes 16.32 seconds, which was also the longest national record in American swimming events at that time. Now, the national records of American 500-meter freestyle, 800-meter freestyle, 1000-meter freestyle and 1500-meter freestyle have been recorded in Ziegler’s name!


    [A swimsuit makes a genius]


    In fact, kate ziegler didn’t show her talent for swimming when she was a child. Even when she was 6 years old, she started swimming training not because she was attracted by the sport, but because the uniform of a swimming team near her home was particularly beautiful, so she cried and begged her parents to buy one for herself. Ziegler recalled: "It was a blue team uniform with beautiful patterns like fireworks. I think it’s so cool. " However, her mother told her that she wouldn’t buy it for her unless she joined the swimming team. "At that time, I cried when I talked." Ziegler said with a smile, "Later, I met with the coach of the swimming team and immediately felt at home. Since then, I have been insisting on swimming down. "


    At the age of 9, Ziegler was once again stumped by swimming, because at this age, children need to change from the 25m pool to the 50m pool. "I remember crying and shouting,’ I’m not swimming! I can’t swim 50 meters.’ "Ziegler laughed and recalled," fortunately, I persisted later. Now I like swimming 1500 meters best. " She is now faster than all the female athletes in the world in this event.


    However, because there is no women’s 1500-meter swimming event in the Olympic Games, Ziegler can only lock her gold medal goal above 800 meters, which makes her feel very depressed. "I can’t understand this situation, but I can’t change it."


    In June this year, Ziegler broke the dusty record of 1500m freestyle with a time of 15 minutes 42.54 seconds, less than 10 days before her 19th birthday. Ray Benecchi, the coach who has been training Ziegler since she was 13 years old, commented on the significance of the new record: "Shortening the record by 10 seconds means shortening every 100 meters by 2/3 seconds, which is like shortening the world record of 100 meters freestyle by 0.36 seconds. Perhaps, 10 seconds is really too much! "


    However, in people’s general consciousness, including the World Championships, the champion of any competition and the world record are not as heavy as an Olympic gold medal. After the National Swimming Championships, Ziegler rested for three weeks, during which he only went into the water occasionally to keep his feeling. "My central task this year is to adjust my state for the Olympic Games. For a long time, there are many really great swimmers who swim very well in non-Olympic years, but they are not remembered because they are not achievements in the Olympic Games. The Olympic Games is a difficult challenge, and I am full of expectations for it. "


    [Homesick girls drop out of school to prepare for war]


    Ziegler defines herself as a homesick girl. "Even if our whole family is going on vacation together, I will say, I want to stay at home and sleep."


    Even though she has become one of the best swimmers in the world, before she graduated from high school in June 2006, Ziegler will still compete on behalf of her O’Connell high school swimming team. Her contract with Speedo, a swimming costume sponsor, was signed in 2013, and her salary was as high as seven figures. However, Ziegler believes that money is not what he values most. "Teammates are more important than making money. I love my alma mater and I feel very comfortable in O’Connell High School. "


    When she gave up her university scholarship to become a professional athlete in 2006, she made a homesick choice again. After visiting Georgia and Florida, she chose to stay in George Mei Sen, where she grew up. "So I can take my clothes home to wash and eat a great home-cooked meal every day. Great, I am close to home, and I can see my mother whenever I want to hug her. "


    Not only that, in George Mei Sen’s men’s and women’s swimming team, Ziegler volunteered to be an assistant coach, and sometimes he trained with the men’s 1500m swimmers.


    The reason why Ziegler temporarily gave up the university scholarship is that she had to concentrate on training one year before the Olympic Games. After the Olympic Games, she will return to school to study for a degree in psychology. "I think if I just swim every day, I will go crazy. I need to find a balance in my life. " Mother revealed that Ziegler has an innate fear of new things, which is why her mother tried every means to coax her daughter into joining the swimming team. "But Kate knows that she has enough good things, and she has enough motivation to do better!"


    [National Team: Second Home]


    Even though it is almost certain that he can represent the United States in next year’s Olympic Games, Ziegler still can’t believe this sudden happiness. "In the past, I have paid attention to the reports of great swimmers like Natalie Coughlin and Phelps. Then I found myself on their team. This is me? Why am I here?’ These people are all heroes in my mind. When someone asks me for photos, I will ask,’ What do you want my photos for? Do you know me?’ When I first joined the national team, I dare say that people didn’t know me at that time. They just saw me wearing the training uniform of the American team. "


    Usually, the famous swimming stars are concentrated in short-distance events, so Ziegler decided to take a high-profile attitude for the sake of the popularity of his long-distance events. As a long-distance runner, she often feels lonely, which is an important reason why she wants to stay with her high school teammates, and then work with her college teammates who can’t compete with her at all and train with her club teammates. She said: "The national team is like another home, just like high school in O’Connell or George Mei Sen. Everywhere I go, I try to build a small circle as warm as home."


    The uniforms of the American team are red, white and blue, and there are no fireworks-like patterns, but it doesn’t matter. Ziegler will add brilliant fireworks himself.
