Many netizens left messages and wanted to see it. Today it came. Let’s look down with Xiaobian.

First of all, from the appearance, the front face of Changan Auchan X7 PLUS is relatively simple and looks very round and lovely. Then the cool headlight design is adopted, and the overall look is comfortable. The car is equipped with LED daytime running lights, automatic opening and closing, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4730MM*1870MM*1720MM. The car adopts dignified lines, and the side of the car presents a delicate design style. With large-size thick-walled tires, the shape is quite clean. In the rear part, the rear looks very simple, the taillights present a fashionable and dynamic design style, and the unique exhaust pipe creates a good gas field.

Sitting in the car, the interior of Changan Auchan X7 PLUS is relatively simple, which is very in line with the tastes of young consumers. The steering wheel of the car is very sharp, equipped with functions such as manual adjustment of the steering wheel up and down, and its practicality and face value are not bad. Let’s take a look at the central control, with a 12.3-inch central control screen, which makes the interior design quite layered and looks quite capable. Finally, let’s look at the dashboard and seats. The dashboard of the car presents a clean and refreshing design style, and the trendy design elements make people remember it at a glance. The car uses a leather-like seat, the seat is wrapped in place, and the overall ride feels soft and comfortable.

Changan Auchan X7 PLUS is matched with a wet dual clutch (DCT) gearbox, with a maximum power of 138KW and a maximum torque of 300N.m, which shows good power performance.

It’s still no problem to put two bags in the trunk of Changan Auchan X7 PLUS. It’s a pity that the rear seats can’t be laid down. In addition, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), brake force distribution (EBD) main driver airbag, co-pilot airbag and front side airbag.

To sum up: the car is a very suitable choice for many families with a moderate size, and the internal space is enough for daily use.

No matter P theory (4P, 12P) or C theory (4C) that marketers must be familiar with; Both IMC integrated marketing theory and SMS social marketing theory can be highly refined into "one center and two basic points".

A center refers to "customer-centered"; The two basic points are "the core buying point of customers, namely UBP" and "the key selling point of products, namely USP".

This also enlightens us that everything must focus on the core target customers of products (tangible products and intangible services), and we must clearly know their needs, requirements and expectations. Know their material and spiritual needs, and then be targeted. Otherwise, no matter how well the following work is done, it will not be accepted by them because it cannot deeply impress them.

The refining of the two basic points is a process of "reluctantly giving up what one loves". If every advantage of the product is emphasized, there are bound to be two extremes:

(1) Distract the attention of the target customers. In the age of information explosion and extremely low patience in 2015, customers can’t remember so many advantages of your product. Emphasizing everything means emphasizing nothing. 　 　

2 If you emphasize everything, it is equivalent to taking all similar products and even non-similar related products as competitors. Therefore, we must be single-minded. Because the more unique, the easier it is to be accepted by customers.

The core content of marketing includes the following 11 aspects:

① To whom — Define the core target customer group;

② What to buy — Find out the core buying points of the core customer base;

③ Who will buy it — Study the users and buyers of products;

④ What to sell — The core selling point of refined products;

⑤ Who will sell it — Set up sales team and find agents;

⑥ Where to sell — Choose a sales place;

⑦ How much — Formulate price strategy;

8 Tell him — Tell the buyer;

9 Keep buying — Pay attention to brand building;

Attending to whom — List competitors;

Who do I learn — Set a learning benchmark. 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　 　

In fact, 100% of the marketing content is planned and set by Ying, and 90% is implemented and executed by Ying (Market Operation Department), and less than 10% is executed by Sales Department (Product Sales Department). Therefore, consumers don’t buy because the work of "camp" is not done or done properly, not because the ability of "selling" is not strong. However, as a member of the "marketing" department, although it is not entirely their responsibility to sell products badly and brands have no influence, if they can "sell" from the height of "market", the results will be obviously different. In addition, only those who have "sales" experience can do a good job in "market", so "marketing" and "sales" must be clearly understood, and the cart before the horse cannot be put.

In terms of "marketing" and "marketing", enterprises should attach importance to and support the work of "marketing" and build and enrich the "market operation department". Only in this way can enterprises attach importance to the work of "marketing" from the aspects of people, money and materials, sales can be smooth, brands can be formed and have the opportunity to gradually become synonymous with the industry.

Enterprises may not know how to do it, but they must know what to do and decide when to do it. After enterprise managers attach great importance to the work of "camp", the personnel of market operation department should not only know what to do, but also know how to do it and be able toBalance the relationship between short-term sales and long-term brand building. If the sales staff can sell from the height of the product market, the results will be very different.

Enterprises have too many good products, but because enterprises blindly emphasize the traditional "sales" and ignore the "marketing" work, the sales are not smooth, and the enterprises are finally in trouble. In addition, even in enterprises with "camp" departments or functions, because "camp" is a department that spends money and "sales" is a department that makes money, it has different status in the minds of entrepreneurs. Different status and circumstances make "camp" a subsidiary of "sales". Instead of using "camp" to guide "sales". As an enterprise, we must realize from the bottom of our hearts that "camp" is to spend small money to make big money, and spend today’s money to make money tomorrow, the day after tomorrow or even longer (the brand can be passed down); And "selling" only earns today’s money and the money of existing products (intuitively, it can be determined that this is difficult to inherit).

What is sales? Find a middleman for a product or service and help the middleman put the product in front of consumers, and you will be qualified for the job. It would be excellent if all the payment can be recovered from the middlemen.

As for whether the product can attract consumers’ attention when it is put in front of consumers, whether it can be picked up after attention, whether it can be bought with money after reading it, whether it can be bought repeatedly after buying it, and whether it can be recommended to friends after repeated buying, that is all the work of the camp.

Everyone can be our customers, but we must find out our unique user groups. Only in this way can we attract them with relatively limited resources; Only in this way can we achieve the maximum input-output ratio. Never expect a product to meet all the needs of a specific customer, nor do you expect a product to meet all the specific needs of all customers, let alone a product to meet all the needs of all customers. The clearer the subdivision, the easier it is to refine the commonness, the easier it is to focus on the outstanding, the easier it is to stand out and the easier it is to be accepted by customers.

Marketing "marketing" and "marketing" are related to each other. Enterprises must clearly understand and master "one center and two basic points", and 90% of marketing will drive 10% of marketing, so as to balance the relationship between short-term sales and long-term brand building, spend today’s money to earn tomorrow’s money, the day after tomorrow’s money or even more long-term money, so that brands can have the tension of long-term inheritance, so as to build a long-term foundation of enterprises.

　 　 1905 movie network news Fukuyama Masaharu, a Japanese actor who made his 25th debut, decided to star in director Hitoshi Ohne’s new film, and Fukuyama played a paparazzi reporter who secretly photographed the entertainment scandal. This is Fukuyama’s second starring role in the film.

　 　 The hero played by Fukuyama is named Ducheng Jing, who used to be the gossip magazine SCOOP! A reporter who specializes in taking exclusive photos, he is still a middle-aged paparazzi who specializes in secretly taking pictures of entertainment scandals in middle age. He is a character who has a sloppy hairstyle and beard, likes gambling at ordinary times and owes gambling debts. The story tells the story of the former tabloid reporter Du Chengjing, who caused a bigger incident after capturing the exclusive news. In addition to Fukuyama, Nikaidou Fumi plays the newcomer reporter Xing Chuan Wildfire; Yoshida sheep and Kenichi Takitoh are deputy editors; Lily Franky plays a strange informant who provides secret information.

　 　 Talking about the feeling of acting, Fukuyama said, "I used to play the role of positive energy, but this time it’s finally different, and I’m still working with Hitoshi Ohne, an excellent director of my age. This is an entertainment film full of joyful elements, which makes me feel a little lonely even after leaving the role. Please look forward to it! "

　 　 This film is the third film directed by director Hitoshi Ohne independently after "Dream Eaters Live Edition". Hitoshi Ohne said, "This work is something I really want to shoot and plan for many years. When I planned to invite Fukuyama Masaharu to play the leading role, this work came to my mind. The film contains thrilling, erotic, sensitive and other elements. I think there are no two people except Fukuyama Masaharu. " It shows Hitoshi Ohne’s trust and expectation for Fukuyama.

　 　 The film SCOOP! It was launched in early October and is expected to be released in Japan in the autumn of 2016.

　　[Pacific Auto Network] Since humans began to use electricity, anxiety about the use of electricity has always existed. Even the appearance of batteries for storing electric energy only slightly eased this anxiety. Just like the hot electric car in the world now, even if there is a fresh experience, it is still impossible to avoid the anxiety caused by battery life.

　　The direct impact of batteries on electric vehicles has also made major new energy sources and battery supplies rack their brains to promote ways to increase battery life. However, whether it is the physical battery stacking scheme, the method of changing the electrolyte composition or even the material form of the battery, the battery life can’t even show a normal state in the face of low temperature. How to keep the battery warm and warm at low temperature has become the key to fight against this "battery killer".

　　In the process of developing and using the battery, we already know that the battery has a normal working temperature range, and the actual use effect of the battery will be greatly reduced in a low temperature environment, so the battery needs a good thermal management to keep it warm in this environment.

　　On April 21st, Changan Deep Blue Brand, a subsidiary of Changan Automobile, held a deep blue technology sharing meeting, at which an item named "Micronucleus High Frequency Pulse Heating Technology" was announced.

　　Just listening to this name, we know that this technology is definitely aimed at the battery thermal management system, especially the word pulse heating exists. Looking back at the technology announced by Chang ‘an this time, in fact, its idea is not complicated. Under the condition of constant heating, let the battery pack heat up more quickly and evenly, so that the battery pack can reach a suitable working environment at low temperature as soon as possible.

Contemporary Amperex Technology Co., Limited patent CN 108711662 B pulse heating device

　　In principle, it is actually based on a patented technology published by Contemporary Amperex Technology Co., Limited. This patent takes advantage of the characteristic that the internal resistance increases due to low temperature. By installing devices that can generate oscillating current at both ends of the battery, the current passes through the battery cells with large internal resistance, so that a lot of heat is generated inside the battery, and finally the battery temperature rises rapidly.

　　Although this heating method can make Contemporary Amperex Technology Co., Limited’s battery pack reach the heating efficiency of 4℃/min, it is easy for the lithium ions in the lithium battery to form dendritic metallic lithium in the process of reduction on the negative electrode, that is, "lithium dendrites". The growth of "lithium dendrite" to a certain extent will affect it slightly, and it will cause internal short circuit of lithium battery, which will seriously threaten personal safety.

　　Therefore, in order to avoid lithium dendrites on the negative electrode of the battery due to frequent over-charging, Changan slightly improved this technology based on Contemporary Amperex Technology Co., Limited’s technology, and chose to use alternating current to generate current for heating the battery pack.

　　Why do you have to mention alternating current? In the previous battery self-heating technology, the current generated was DC. According to the physical definition, the current whose magnitude and direction do not change in unit time is called direct current. Looking back at the conditions for the generation of "lithium dendrites", it is too late for the negative electrode to treat lithium ions during the discharge process, resulting in the appearance of metallic lithium.

　　The negative electrode of the battery that needs breathing time is easy to reach the limit in the face of constant output of direct current, and then it is easy to appear "lithium dendrite". Therefore, in order to weaken this "invariability", it is necessary to give the negative electrode some breathing space, and alternating current with periodic changes in the magnitude and direction of current per unit time is more suitable for this work.

　　Unlike direct current, alternating current does not always keep a constant value, but it always keeps a periodic change of positive value -0- negative value -0- positive value. It is precisely because of this unsteady characteristic of alternating current that the burden on the negative electrode of the battery can be reduced, thus reducing the probability of lithium dendrites.

　　At the same time, Chang ‘an also mentioned the semiconductor IGBT (insulated gate bipolar transistor) at the meeting. IGBT is a switch that is either on or off. It has no function of amplifying voltage. When it is on, it can be regarded as a conductor, and when it is off, it can be regarded as an open circuit. Coupled with the cooperation of the motor and BMS system, random high-frequency current charging and discharging switching can be realized, which further reduces the occurrence of lithium dendrite.

　　The dark blue C385 power battery pack officially announced by Chang ‘an can keep the heating rate of 4℃/ at the ambient temperature of minus 30℃, and can improve the power performance by 50% and shorten the charging time by 15% at the ambient temperature of minus 30℃. From the data point of view, the improved "battery self-heating" technology is not only more efficient, but also has a longer battery life, which is quite good news for users in low temperature areas.

　　At present, the mainstream types of batteries on the market can be divided into two types according to the element types, namely ternary lithium batteries and lithium iron phosphate batteries. The biggest difference between them is the different cathode materials used.

　　Lithium iron phosphate battery uses Ferrous lithium phosphate (PO4) as cathode material. Its advantage is that it is very safe at high temperature or overcharge, but its disadvantage is that at low temperature (below -10℃), the lithium phosphate battery decays very quickly. After less than 100 charge and discharge cycles, the battery capacity will drop to 20% of the initial capacity, which is basically insulated from the use in cold areas.

　　Ternary lithium batteries are lithium batteries made of lithium nickel cobalt manganate (Li(NiCoMn)O2, NCM) or lithium nickel cobalt aluminate (NCA). Nickel salt, cobalt salt and manganese salt are adjusted in different proportions, so they are called "ternary". For example, NCM811 in Contemporary Amperex Technology Co., Limited means that the ratio of nickel, cobalt and manganese is 8:1:1.

　　The advantage of ternary lithium battery is its high energy density, both of which are made in Contemporary Amperex Technology Co., Limited. The energy density of its lithium iron phosphate battery is 178Wh/kg, while that of NCM523 is 200Wh/kg and that of NCM811 is 240Wh/kg. In terms of low temperature, ternary lithium battery can also maintain normal battery capacity at -30℃, which is more suitable for the use conditions in the northern low temperature area. The disadvantage is that the ternary material of ternary lithium battery will decompose at 200℃ at high temperature, and it is easy to burn or explode at high temperature.

　　Although the materials, advantages and disadvantages of the above two batteries are different, from a microscopic point of view, their working principles are also the process of lithium ion migration back and forth between the positive and negative electrodes.

　　In the low temperature environment, the activity of the anode and cathode materials of the battery decreases, and the conductivity of the electrolyte as a bridge also decreases. Therefore, when the battery is charged and discharged, there will be resistance inside, which is called internal resistance. When the internal resistance of the battery increases, during the normal use of the battery, a lot of Joule heat will be generated to cause the battery temperature to rise. Experiments show that when the environment is below 0℃, the internal resistance will increase by about 15% for every 10℃ drop in temperature.

　　Being hindered by internal resistance, trying to exert force can only lead to excessive discharge of the battery, and the electric energy is continuously converted into heat energy, which not only reduces the power, can’t output power normally, but also easily affects the safety of the battery. All these results are caused by the low temperature environment.

　　In order to solve this problem, in addition to the latest "pulse self-heating" technology mentioned above, in fact, suppliers and manufacturers have done a lot of "warm" measures.

PTC element

Heating film

　　At present, there are several common schemes. The first one is PTC and heating film selected by most pure electric vehicles. The idea of this scheme is to heat the battery through external electric heating elements to improve the battery temperature. There are two kinds of PTC: water heating and air heating. Water heating heats the coolant through PTC and then exchanges heat with radiator. Air heating means that after the warm air is turned on, the cold air directly exchanges heat with PTC and finally blows out warm air. The heating film is like covering the battery with a conductive heating quilt, but both of them have obvious shortcomings. PTC is easy to cause uneven heating and occupy the space of the battery compartment. Because of the safety, the overall cost of the heating film is not low, and the actual heating efficiency is not high.

　　Another scheme is the liquid cooling circulation system, which is like adding a set of heating to the battery pack, and heating the coolant to obtain a long-term heat source. Another scheme is heat pump air conditioning. The whole principle is like the forced extraction of atmospheric heat into the car, but when the ambient temperature is too low, the heat pump is easy to fail, so a "magic change" is also made, which not only extracts the heat from the outside air, but also collects the waste heat generated by the power battery system, the drive system and the PCS power electronics. The whole system relies on the eight-way reversing valve for complex heat extraction, so as to improve the overall efficiency of the heat pump air conditioning.
