When the night is getting deeper, Ozawa, who gets off work, often habitually goes to the Ziyan Baiwei Chicken Store at the intersection and packs a stew to take home. On the way, he will also open the service number of "Ziyan Baiwei Chicken" to check the brand dynamics. Since mid-May, Ozawa has found that the brand weekly published by Service Number has added a "food safety column" to specialize in popular science food safety knowledge. "At first, I introduced why beef glows green. Later, I taught you how to identify yuba. Recently, I shared tips on how to prevent food poisoning in hot weather." Ozawa said, "These contents are both practical and answer some of my previous questions about the product."

The design of "Food Safety Column" is actually just one of the epitome of Ziyan’s food safety work. Over the years, Ziyan Food has created a set of closed-loop quality control that runs through raw material screening, production technology, cold chain logistics, store management and even consumer feedback, so that every braised taste is more secure from the source to the tip of the tongue.

Good raw materials+good technology = good products.

"It’s delicious and suitable for eating." When talking about the reasons for loving Ziyan food, Ozawa gave the above reasons without thinking, and said, "I got off work late, and it was troublesome to fry a menu and two dishes. At this time, it was just right to take a braised taste of Ziyan home on the road." In Ozawa’s view, Ziyan food is not only delicious, but also has eye-catching new products from time to time, but among all the products, I still love husband and wife lung slices best.

According to the 2024 annual report, Ziyan Food’s annual revenue was 3.363 billion yuan, of which 991 million yuan was sold only for the single product of husband and wife lung slices, accounting for nearly 30%. The back of a good product is inseparable from the support of good raw materials and good technology. In the course of long-term business cooperation, Ziyan Food has established long-term and stable cooperative relations with a number of large suppliers, such as Wenshi, New Hope and COFCO, on the main raw materials such as whole chicken, beef and duck by-products. For non-bulk commodities with special procurement needs, Ziyan Food will lock in the production capacity resources and product prices of high-quality suppliers by signing long-term cooperation agreements and price locking agreements, thus effectively ensuring that the company can obtain sufficient high-quality raw materials at reasonable cost in time. The arrival of raw materials in the factory is only the first step. After entering the factory, each batch of raw materials has to go through the joint acceptance system of Ziyan "food safety+production+storage". Only raw materials that pass strict inspection and meet the quality standards can be allowed to enter the production process.

On the other hand, Ziyan Food puts forward precise requirements for curing time, cooking temperature and time of each product in combination with modern technology to ensure the stability of taste and quality.

In addition to inheriting Sichuan brine technology, Ziyan Food is constantly learning and researching other excellent practices. On May 28th, 2025, the Rongchang District Government of Chongqing agreed to use the name "Rongchang Braised Goose" in Ziyan’s factory. Through the standardized production system, Rongchang braised goose will reach all sales terminals directly, realizing the consistency of quality and flavor. In the research and development of new products, Ziyan is not limited to Sichuan spicy taste, but also actively expands the diversified flavors such as sour soup, rattan pepper and spiced to meet the consumption preferences in different regions of the country.

Smart cold chain logistics escorts quality.

In order to live up to the good products made by good raw materials and good technology, Ziyan Food regards product quality as the lifeline of enterprise development, and has passed ISO9001 quality management system certification, ISO22000 and HACCP food safety management system certification and FSSC22000 food safety system certification, and has strictly controlled the quality from beginning to end, creating a comprehensive quality control system covering procurement, production, warehousing, product distribution, terminal sales and other links. In 2025, Ziyan Baiwei Chicken was awarded the certificate of "Group Member of China Quality Inspection Association", and the quality management and industry standardization construction were recognized by the authority again.

At present, Ziyan Food has established five high-standard production bases in Jinan, Shandong Province, Wuhan, Hubei Province, Lianyungang, Jiangsu Province, Ningguo, Anhui Province and Chongqing. By introducing advanced production facilities and technologies, it has realized a series of automatic innovations such as batching and reporting, reduced human intervention variables, and realized visual management and detection of the production process, ensuring product consistency and production efficiency.

A good product leaving the factory is only the beginning of the test. How to make these products with short shelf life pass through the logistics link efficiently and safely and reach consumers without damage is an unavoidable issue. In this regard, Ziyan Food realizes direct, efficient and fast distribution from the factory to the store through self-built cold chain logistics fleet, and maximizes the product life cycle. At the same time, the intelligent cold chain logistics service platform is applied, and advanced technical means such as Internet of Things, GPS positioning and remote temperature monitoring are introduced. After the logistics order is automatically generated and delivered with one button, the temperature, humidity and location information of goods in transit are monitored in real time, which greatly reduces the distribution error rate, maintains the freshness and taste of products to the greatest extent, and keeps the bottom line of food safety.

The location of the above five bases also helps Ziyan Food to form an all-round supply chain system with the optimal cold chain distribution distance as the radiation radius, fast supply and maximum preservation, and realize the scene of "placing orders the day before, producing on the same day, and delivering to the store on the same day or the next day". The direct, fast and low-cost product distribution effect provides a solid supply guarantee for the rapid expansion of the company’s sales scale. Based on the strategic layout, after the completion of the project of Hainan Ziyan Food Processing and Production Base, the supply chain network of Ziyan Food will be more perfect, and the delivery timeliness is expected to be further improved.

It is worth noting that the quality control management of Ziyan Food is not static, but is constantly evolving in combination with digital and information technology. At present, Ziyan has established a set of highly integrated digital management ecology, introduced modern electronic information management systems such as SAP-ERP system, sales center system, OA system, TMS system and WMS system in food industry, realized the systematic management of core business, completed the integration of different systems, and realized the integration of financial and business information and the real-time acquisition of sales information in terminal stores. On this basis, Ziyan Food continues to explore digital applications, make cross-regional market forecasts and feed them back to production, R&D and procurement in time to improve the company’s operational efficiency.

Terminal multidimensional prevention and control food safety risk points

When the products arrive at the store, they are faced with strict management procedures. Through the deployment of high-definition network cameras, intercom multimedia terminals and other facilities, Ziyan Food has built a real-time monitoring network for stores directly managed by the headquarters, and standardized supervision of terminal operations. In terms of environmental sanitation, Ziyan Food has set up a triple guarantee with the store self-inspection system, the irregular spot check by the national inspection team and the third-party professional disinfection service. Its small cooked food window, which was first adopted and always adhered to, made the clerk and the customer have almost no contact from ordering to taking the meal, and built the last physical barrier for the safe delivery of food.

The preservation management of terminal food forms a collaborative closed loop with the upstream supply chain through digital technology. Among them, around the fresh products that require high freshness, in order to ensure the timeliness of production and supply, Ziyan established a sales forecasting system. By analyzing the medium and long-term store sales data, short-term store sales data and product market demand, it predicted the order quantity of the store on the same day, thus giving production plan suggestions for different products. The production department manually reviewed the forecast data to form a production plan and arranged production in each production base. In terms of product distribution, the company’s middle desk system summarizes the product orders sent to the company by franchised stores and direct-operated stores at the specified time, and the company’s middle desk system automatically matches the orders with the inventory. After manual review, the production bases deliver the goods according to the store orders and deliver them in cold chain.

Ziyan Food also pays great attention to consumers’ shopping experience, and has an evaluation machine in the store, which further opens the channel for consumers’ feedback to the headquarters, ensuring that customers’ feedback can be collected and responded at the first time, thus improving the quality of the store and making product optimization and service improvement more targeted.

In addition to the above links, Ziyan Food has also formulated detailed management norms in tableware disinfection, sales operation and other aspects, and implemented them through training, supervision, inspection and other forms to standardize the unified and standardized operation of stores. Among them, in 2025, Ziyan Food launched three rounds of food safety strategy training covering the whole year, involving headquarters operations, operators and stores, covering food safety standards, store management, personnel health management and other dimensions, and continuously strengthening food safety risk prevention and control capabilities.

From the rigorous screening of raw material procurement to the improvement of production process, from the intelligent management and control of cold chain logistics to the standardized operation of terminal stores, Ziyan Food’s high requirements for full-link quality control not only help itself to open up a larger market scale, but also provide a typical paradigm for the quality upgrade of traditional lo-mei flavor. Under the background of the rise of quality consumption, Ziyan Food is guarding the core of traditional flavor by means of industrialization, improving industrial efficiency by digital technology, and writing a new industry sample for the high-quality development of the table-stewed track.

A complete food chain consisting of large to medium-sized mammals, which is extremely rare in China, is born in the experimental area of Northeast Tiger and Leopard National Park. The flagship species, Northeast Tiger and Leopard, is undoubtedly the king who occupies the top of the ecosystem food chain.

At present, the primitive natural forests in the temperate zone of the northern hemisphere are very limited, only distributed in three areas: northeast North America, eastern Europe and northeast Asia. Among them, the temperate coniferous and broad-leaved mixed forest in northeast Asia has the highest biodiversity, which has become a refuge for a large number of species and is a rare "species gene bank" and "natural museum" in the world.

The experimental area of Northeast Tiger and Leopard National Park system is located in the center of Asian temperate coniferous and broad-leaved mixed forest ecosystem, and the most complete and typical wildlife population in Northeast temperate forest is preserved in this area. At present, a complete food chain consisting of large to small mammals, which is extremely rare in China, is born in the pilot area. Carnivorous fauna includes large Siberian tigers, leopard, brown bears and black bears, medium-sized lynx, green ferret and Eurasian otter, and small leopard cats, sable, Yellow weasel and mink. Herbivorous fauna includes large red deer, sika deer, medium-sized wild boar, Siberian roe deer, musk deer, impala and so on.

The vast forest sea in the pilot area has also become a paradise for birds to survive and reproduce. Every spring, all kinds of forest-dwelling birds such as flounder, thrush and stork begin to return from the south to prepare for the breeding that year. The Tumen River Estuary Wetland, which is located next to the pilot area, is listed as a key bird area in Asia, and the spectacular migration army of geese and ducks stops here every year to replenish energy.

The fertile forest environment in the experimental area of Northeast Tiger and Leopard National Park also provides a good living environment for reptiles such as brown-black snake, red-spotted snake, white-striped snake, tiger-spotted snake, East Asian abdominal chain snake, Ussuri Agkistrodon, and black-browed snake.

The pilot area is close to the Sea of Japan. Under the influence of marine climate, the environment here is humid and the water system is developed. Suifenhe, a famous transnational river, originated in the experimental area of Tiger and Leopard National Park in Northeast China, and important tributaries of Tumen River, such as Hunchun River, cross the experimental area. Abundant water sources provide a good survival foundation for amphibians such as China Rana chensinensis, Oriental bell toad, rough-skinned frog, flower-backed toad and giant salamander in the extreme north, and at the same time, it also nurtures rich fish resources, such as salmon, Yarrow fish and Ochoa fish. It is worth mentioning that a small and medium-sized cold-water rare fish-spotted salmon, which grows here, is one of the five most famous salmon species in the world, and only lives in areas with dense forests and fast and clear water flow on the upper reaches of Tumen River, Suifenhe River and Yalu River.

In recent years, the better ecological environment and the more effective protection measures in the experimental area of the Northeast Tiger and Leopard National Park have made wild Siberian tigers and leopards appear frequently, and the "news" that they appeared sporadically in the past is slowly changing into "daily". According to the latest data, the number of wild Siberian tigers and leopards has increased from 27 and 42 at the beginning of the pilot project to about 40 and 50 respectively, and more than 12 cubs and 11 leopards have been newly discovered. There are about 27 orders, 78 families and 355 species of terrestrial wild vertebrates in the region, including 10 species of national first-class protected wild animals. Chinese merganser, sable, musk deer, roe deer, impala … these animals, which were once rare or even extinct for many years, frequently appeared in groups, and from crossing the road to settling down, they used their footprints, whistling and beautiful photos to "like" the ecological construction of the Northeast Tiger and Leopard National Park system pilot.

In recent years, China’s economic transformation, the real economy is facing great transformation pressure, but the tourism market has developed rapidly. According to statistics, in 2017, China’s domestic tourism consumption reached 840.9 billion US dollars, which has risen from the fourth place in 2008 to the first place, surpassing the US’s 820.8 billion US dollars, and has become the largest domestic tourism market in the world.

In recent years, more and more people have money and leisure, whether young white-collar workers or retired old people, or farmers who have begun to pursue the quality of life, whether from the perspective of consumption power or the number of consumers, or from the perspective of newly opened tourist attractions and new tourist facilities in various places, China’s tourism industry is facing great development prospects.

Tourism means travel, of course, it is inseparable from transportation. With the widespread popularity of private cars and the daily demand for travel, the concept of tourism is being ignited among the people, and it seems that it will become the next emerging blue ocean market after domestic peace.

The direct reason should be that following the announcement of the launch of a compact model, a model named was soon launched, but after harvesting the feelings of a wave of young fashion people, the market sales quickly fell into a downturn, and now it is basically close to the edge of production suspension.

For joint venture car companies that have advantages in brand and technology, this lesson should be profound. It is no longer feasible to try to seize the local market in China by directly importing foreign concepts and mature products from multinational car companies.

And those BBA’s are probably just the minority feelings of some urban youth.

China’s huge local travel market has its own rules, of course. The basic national conditions of China, the usage scenarios and habits of travel users determine the demand of China people. With the rise of great powers, cultural self-confidence has been established, and the standards of this market must be defined by China travel enthusiasts themselves.

In the past two years, with the further maturity of the China market, Chinese people no longer blindly follow the trend. Users who need more long-distance use tend to take a fancy to the large space and passability advantages, and then take the initiative to choose.

Compared with the small territory of European countries, China is more vast, and the climate, topography and road conditions are more complicated, which determines that the travel users in China need cars with more functions, better adaptability and better comfort. Wagon models developed on the basis of European hatchback cars have relatively insufficient internal space for the travel needs of large families in China. Moreover, European cars are generally hard, which has not been significantly improved in the domestic market. For long-distance driving, the comfort will inevitably not be guaranteed.

If you don’t get enough relaxation and rest during the trip, it will be difficult to complete all the punching of a travel plan.

Therefore, a car that is more close to the people and understands the needs of China people is the model of the China market.

Jietu brand, which focuses on the "Travel+"market segment, has taken a fancy to its development opportunities and space. After 15 months of listing, its sales volume has exceeded 158,000, and its Jietu series has become a "dark horse" in the auto market, rising against the market in the cold winter, consolidating the leading position in the "Travel+"market segment. On November 28th, Jietu X95, a brand-new subsidiary of Jietu, was officially listed. The new car is medium-sized, with a total of 6 models and 5/6/7 seats available. It is equipped with 1.5T and 1.6T models, and the official guide price is 99,900-150,900 yuan. It is highly competitive in the market with almost no strong competitors, and is expected to become another explosion of the Jetway series. Behind the phenomenal success of Jietu, Li Xueyong, general manager of JETOUR Jietu Marketing Center, attributed it to the focus and intensive cultivation of the "Travel+"market segment. According to the plan, Jietu’s sales in 2019 are expected to exceed 130,000 vehicles, and the challenge target of annual sales of 200,000 vehicles is set for next year, which means that it will achieve a year-on-year growth of 35% and at the same time enter the "top eight" of its own brand.

In terms of appearance design, Jetway X95 continues the family-style design of Jetway "Huizhou City Leader". The hexagonal air intake grille is huge in size, with dense lattice design inside, which has a very high degree of recognition.

On the other hand, the complicated multi-waistline design on the side enhances the overall three-dimensional impression, and the B/C/D column is painted in black with chrome trim, forming a more dynamic suspended roof effect. Its length, width and height are 4875mm/1925mm/1780mm respectively, reaching 2855mm. The rear of the car, which takes a simple route, conveys a bit of breath.

Entering the car, Jietu X95′ s surrounding interior design, with black as the main color tone, looks simple, atmospheric and full of scientific sense. The 12.3-inch central control large screen +12.3-inch LCD instrument +9.7-inch touch air conditioning screen has three large screens, bringing the scientific and technological experience of "three-screen interaction". The car has also changed from a traditional reflective glass to a multimedia system independent of the central control display screen, and has integrated rich functions such as driving recorder, navigation, Bluetooth call and voice control.

Although the price is very close to the people, in terms of sensory quality, Jietu X95 is very fastidious in detail design. The central control knob decorated with chrome-plated materials and the metallic sound cover at the door panel further demonstrate the high-end temperament of Jietu X95, while the piano painted door panels of the two side doors and the co-pilot center console are decorated with elegant "story-telling starry sky" atmosphere lights (with seven color changes), which can even "breathe" according to the rhythm of the sound that is also the best in its class.

In addition to the conventional configuration, in terms of intelligent security configuration, Jietu X95 has also reached the level of about 250,000 yuan in the current joint venture medium-sized. The whole system comes standard with J-Control intelligent driving system, Carlife, etc. The high-equipped models are equipped with car wireless WiFi, full-time interactive voice control system and car networking. In terms of intelligent assisted driving, high-profile vehicles provide many functions, such as 360 HD parking system, rear blind spot vehicle identification warning system (BSD), lane change assistance (A), rear cross collision warning (RCTA), door opening warning (DOW), front vehicle radar monitoring anti-collision warning system (FCW), fatigue prevention (LDW) and so on.

In terms of power, Jetway X95 has not been neglected because of its close pricing. On the contrary, Jetway X95 is equipped with 1.6T in-cylinder direct injection, which is the strongest power of its own brand at present, and the latest technological achievements, which is specially made for Guoliu B. Among them, this one is 145kw, and the peak torque is 290N·m, which is matched with the 7-speed wet dual clutch of Gertrak and the same powertrain. A big car doesn’t mean a high one. According to the official measured data, the 100-kilometer comprehensive of the new car’s 1.6T+7DCT model is 8.1L, while that of the 1.5T+ model is 7.7L.

For the deep cultivation of the "Travel+"market segment, Jietu’s understanding and operation have far exceeded the scope of product marketing. From the family-style design of "Huizhou City Leader", we can see that Jietu brand has a strong China traditional culture, which combines product innovation with cultural inheritance, creates a unique brand DNA, and is "unique" among the existing China brands, which has been affirmed and favored by users, and has also promoted traditional culture to the society and received good social effects. Although it has a strong imprint of traditional culture, the marketing level is not closed and conservative. Combining with "internet plus", Jetway has created a unique traveler cultural ecosystem, effectively integrating the travel industry, travel culture and industry, and at the same time, actively deploying new retail with innovative thinking, expanding user experience and contact points, and walking ahead of the peers. Undoubtedly, compared with those "foreign brands" that are "above the top", Jetway can resonate with China travel enthusiasts more.

In Jietu, we have seen a bold attempt in marketing methods and user experience. Jietu builds a fan alliance from the level of experience and sharing, looks for the leader, carries out activities, and forms a circle between users; At the same time, Jietu has cooperated with a large number of local catering, entertainment, entertainment, tourism and other different companies, which not only brings cross-border traffic implantation, but also establishes a multi-level ecological alliance and builds a really effective value circle.

For example, if you are a member of Ctrip Gold Card, you can enjoy the corresponding privileges and enjoy VIP treatment when visiting Fangte. At present, Jetway has established many unexpected ecological circles all over the country, including Jetway Fan Culture Festival, Jetway Family Banquet, Travel+Ecosphere Experience Day, Jiemeng, etc., which can bring special and real courtesy to users.

With bold marketing innovation, Jietu is full of vigor. On the night of November 28th, Summer, a singer who has been conveying vitality to everyone with her healthy image, returned to her "second hometown"-Shancheng, and became the chief travel experience officer of Jietu brand under the holding company.

"Have you ever tried a’ walk and go trip’?"

"Of course, I am an’ activist’, I won’t do any raiders, take the car keys and start at once!"

In the eyes of many on-site audiences, Summer has a high degree of fit with the Jetway brand and the protagonist of the night-"brand-new Jetway X95": they are all yearning, full of courage and sporty temperament, and they are simply "tailor-made".

As a "first-class travel" tailored for China travel enthusiasts, Jetway X95 has naturally made great efforts in comfort. The new car uses a large number of soft and environmentally-friendly plastic-lined materials, and the leather wrapping (known as 360-degree soft touch) everywhere is kind. Johnson’s advanced comfortable fine leather wide-body seat not only has NAPPA texture that young people like, but also is satisfactory in filling and wrapping. In addition, the front driver’s seat supports functions such as electric adjustment, lumbar support and position memory.

To achieve such a diversified presentation of customer value, those "high above" European departments obviously have a long way to go from Jietu. Whether it is a large number of middle-aged and elderly people who are happy to enjoy life and travel, or a new generation of consumers who are full of yearning for tourism, they are becoming more and more rational and are not simply blind to brands, because they know that what is suitable is the best!

★ Coating of Mercedes NANOSLIDE Cylinder and Honing Process of CONICSHAPE Cylinder

　　It is reported that compared with the traditional cylinder liner, the patented technology of Mercedes-Benz can reduce the friction loss of the cylinder by about 50%, the heat can be conducted to the cooling system more quickly, the compression ratio can be set higher, and the engine oil with lower viscosity can be used.

　　At the same time, the small holes on the surface can’t store the engine oil normally. After the engine oil is brought into the combustion chamber by the piston, the carbon deposition will become more and more serious, and the price of future maintenance is much higher than that of engines using cylinder liners.

★ CAMTRONIC variable valve lift and piezoelectric injector

　　Among them, the intake valve can be opened in the crank angle range of 4 before TDC to 36 after TDC, and the exhaust valve can be closed in the crank angle range of 25 before TDC to 15 after TDC. This adjustment method can make the valve overlap angle change in a wider range, thus obtaining more economical ignition timing.

　　On the one hand, the adjustable valve lift can ensure the best combustion effect by combining multiple fuel injections with multiple ignition of spark plugs (generally 5 times), and can also make up for the reduced turbulence of combustible mixed gas in the combustion chamber.

　　However, multiple ignition will greatly shorten the life of spark plugs, that is to say, in the current generation (|), the life of spark plugs is about one-fifth of that of ordinary single-ignition engines.

★ New turbine technology

　　In the brand-new engine, the 2.0T version will add an electric turbocharger on the basis of the exhaust gas turbine, that is, the configuration of double turbines. It is reported that the C300 model will be equipped with this engine.

　　The electric turbine is equipped with a brushless DC motor, which has the ability to increase the speed to 7000 rpm in 0.3 seconds. The turbo lag phenomenon can almost be avoided, but according to foreign media, the energy consumption of this electric turbocharger is still relatively large.

　　The electric exhaust gas turbine is connected with the engine cooling circuit, and the maximum speed can reach 170,000 rpm, which can achieve a very high airflow speed and keep the boost pressure for a period of time. Even if the driver has started braking, he can respond quickly when power is needed.

★ Full text summary

　　The fully optimized M254 1.5T+48V light-mixed engine, with the blessing of the above advanced technologies, is a completely new change compared with the previous generation models, and finally returns to the same starting line as BMW and Audi’s 2.0T, and the strategies of electrification and energy saving and emission reduction are equally significant to enterprises. However, from the consumer’s point of view, the nightmare of M264 is not far away, and the brand-new M254 is bound to make consumers pay more attention to it, just as the brand-new C-class has exposed problems such as central control screen, driver assistance system failure and passive safety system failure, which inevitably makes people sigh that things are good things, but it still has a long way to go to make consumers accept them.

　　[Professional Test] It is not enough to look at the comprehensive endurance of a pure electric vehicle. First of all, the comprehensive cruising range is tested in an ideal test environment, and the road environment in real life is much more complicated than the test environment; Secondly, if you only drive on the highway at a relatively high speed, the actual cruising range will definitely be less than the comprehensive cruising range, because high-speed driving is a working state with high energy consumption for pure electric vehicles. However, as a car, it is also one of its "jobs" to run long distances and take high speed. So how does a pure electric vehicle with a comprehensive cruising range of more than 450km perform at high speed? Today, we found such a car and tested it for everyone.

　　The 2018 500 is a new model launched by Tengshi in March this year. Like the old models, it is positioned as a medium-sized pure electric vehicle. The biggest highlight of the car is its comprehensive cruising range of 451km, which is due to its lithium iron phosphate battery with a capacity of 70kWh. The car has two models, the fashion version and the glory version, and the latter is the top model of the car. Today, the test car we got is Tengshi 500 Glory Edition. Apart from the difference in configuration, the powertrain is also different. From the data point of view, the power performance of Glory Edition is better.

After reading the following, you have read 70% of the full text:

　　1. The comprehensive cruising range of the Ministry of Industry and Information Technology of the new car has increased to 451km, which is 99km； more than the old model;

　　2. It can travel 290km under high-speed working conditions, and the charge after high-speed driving can reach 57kW, and 80% of the power can be recovered in about one hour;

　　3. Driving for 200km in urban areas, with a remaining cruising range of 240km；;

　　4. The dynamic response is good, and the acceleration of 0-100km/h is 9.65 seconds.

　　If you want to know how these results are tested, and what kind of reference value these results have in your travel and driving process, please see our test content later.

● Endurance test

　　In order to carry out the endurance test closer to the real car scene and give friends who are concerned about pure electric vehicles more meaningful endurance test results, we will conduct the test according to the following conditions in the future:

　　1. During the high-speed endurance test, the average speed is 90km/h 2 km/h, and this speed setting will basically be achieved by using the speed of 100-120km/h most of the time in the actual driving process. This operation is to restore the actual car scene on the expressway as much as possible, and it will not lead to dangerous high-speed driving behaviors such as slow driving and speeding.

　　2. During the low-speed endurance test, the average speed is 30 km/h 2 km/h, which can simulate the actual situation of the vehicle as much as possible, including waiting for traffic lights, traffic jams, high-speed loop driving, etc.

　　3. During the test, if the air conditioner is turned on, we will record the turned-on state (cold and warm air) and the turned-on time in detail. After all, on pure electric vehicles, the air conditioning components are considered as high-power electrical appliances on the car, and we will explain to our friends how the air conditioner affects the cruising range.

　　First of all, before introducing the test process in detail, we will show the results of the endurance test to our friends. Because the power display of Tengshi 500 is not an accurate value, the following power values are all estimated values:

◆ High-speed battery life: "far" running and fast charging.

　　Tengshi has used the recent average energy consumption to calculate the remaining cruising range since the first model. This algorithm will calculate according to the recent energy consumption state and remaining power, and show how many kilometers the vehicle can travel under the current energy consumption state. It is somewhat similar to the computational logic we have tested before.

　　If the energy consumption state of a vehicle changes constantly through a variety of complex road conditions during a trip, the remaining cruising range value will also change frequently: the high-energy time-consuming value will decrease sharply, and the low-energy time-consuming value may increase. At first, it may make drivers feel confused and don’t know when to refer to the value, but this algorithm actually reflects the remaining endurance of the vehicle at a certain energy consumption level and can remind drivers of the influence of driving style on the endurance of the vehicle.

　　Judging from the models we have tested at present, we can travel 290km at an average speed of 90km/h, which is quite good among pure electric vehicles. Without charging in the middle, you can run to Shijiazhuang with full charge (Baidu map query is from Zhongguancun in Beijing to Huaibei Park in Shijiazhuang, the whole journey is 289.7km, and it is basically no problem to drive at high speed). However, due to the weight of the car and the wind resistance of the car body, the power consumption per 100 kilometers at high speed reaches 20.9kWh/100km, and the energy consumption level is still relatively high. However, Tengshi 500 power battery itself has a capacity of 70kWh, so 15% of the power can still support the car to travel 52km in this energy consumption state. If you drive on the main highway, the remaining cruising range can basically reach the next charging station in the service area.

　　Although Tengshi 500′ s high-speed endurance performance is good, here we still suggest that friends plan the interval of charging stations at 280-290km for high-speed travel to avoid the situation of power failure. In winter, it is necessary to reduce the mileage interval of route planning. After all, air conditioning and warm air consume more electricity than air conditioning and refrigeration.

◆ Charging performance: the battery will charge quickly when it is hot.

　　From the charging information, we can see that when the temperature of the power battery reaches 41℃, the charging current and voltage are relatively high. According to the charging power displayed on the charging pile, the charging power is about 57kW. If charging in this state, the power of the power battery can be charged in one hour. According to the conversion of 70kWh into percentage, the charged power is about 81%. It can be seen that it is possible to charge the power battery to 80% within one hour when the temperature of the power battery is high.

◆ Low speed battery life:

　　Driving at an average speed of 29.5km/h for 200km consumes about 51% of electricity, leaving a battery life of 240km. Although this achievement does not exceed the cruising range of the Ministry of Industry and Information Technology for 451km at present, according to the measured cruising capacity, it is completely possible to charge once a week if the commuting distance is 40km per day. Not only that, even if the power is not enough, it will remain at about 50%, and the travel needs of other urban areas outside the daily commute or to and from the airport can still be met.
