Safety of Dongfeng Nissan ARIYA ARIYA

I don't know when it started, and the focus of new energy vehicles changed from endurance and intelligence that everyone began to pay attention to to to safety. When it comes to new energy vehicles, people will unconsciously think, is this car safe? Whether it is body safety or battery safety, in short, safety seems to be the standard to judge whether a new energy vehicle is qualified.

I bought my first pure electric car as early as 20 15, and Nissan went to China for a morning breeze. Just opened most new energy vehicles on the market, and bought them like real cars. Chassis texture, driving experience, especially battery safety attracted me. Nissan still maintains the "miracle" of 2 1 100 million kilometers battery safety accident. Although the second-generation products of Leaf did not enter China, Dongfeng Nissan brought ARIYA Aria to China. As an old car owner related to this car, let's discuss the black technology of battery safety with you.

Aria Aria is the first global strategic model of Nissan NEXT, backed by Nissan's top pure electric platform in the world. Its unique design, excellent performance and comfortable driving experience all make it have the potential of a pure electric market changer. I first saw this car at the 20 19 Tokyo Motor Show. At that time, I said it would be great if I could buy it in China, but I didn't expect it to be realized in a few years.

ARIYA ARIYA's oriental design language gives ARIYA ARIYA a sense of the future that no Nissan car had in the past. It has little to do with the design of traditional fuel vehicles in the family. The enclosed grille with luminous LOGO caters to the public's taste, and China Net still has the ancestral design language of Nissan V-Motion.

The length, width and height of ARIYA ARIYA are 4600× 1900× 1658 mm respectively, and the wheelbase reaches 2775 mm, bringing a leap-forward space experience. This is not the "stealing space" of other car companies at the expense of the comfort in the car, but based on Nissan's 76-year pure electric heritage and more than 25 years of battery technology accumulation, which is highly integrated with the self-developed three-electricity technology and has a professional cloud image. It is designed according to the characteristics of pure electric vehicles. The flat battery compartment shortens the front and rear suspension, reduces the center of gravity of the platform, and all components are moved to the front engine room, forming a platform similar to a skateboard. So this platform also has a very interesting name: "Morph carpet". Another thing I have to say is that Nissan did a lot of consumer surveys before mass production and obtained the real demand of consumers.

The dual 12.3-inch integrated screen, the concave corner of the instrument panel and the inclined direction of the central control panel have all been carefully designed, and the new generation car networking system Nissan Connect Chaozhilian is also more easy to use.

Under the stunning appearance and interior, the black technology of Dongfeng Nissan is hidden. EESM electric excitation synchronous motor, with maximum power 178kW and peak torque of 300n·m, matched with ternary lithium battery with capacity of 90kWh and battery density of 155.8Wh/kg. The two-wheel drive version of CLTC has a pure battery life of 623 kilometers, and the four-wheel drive version of CLTC has a pure battery life of 559 kilometers due to the improvement of motor power and performance.

Protecting the lifeline of users is the insurmountable bottom line of Dongfeng Nissan. Safety, especially the safety of the "big heart" of the battery, is one of the * * * characteristics for users to choose ARIYA ARIYA.

Chen Haocun, assistant general manager of Dongfeng Nissan Automobile Sales Co., Ltd. and general manager of Dongfeng Nissan New Energy Automobile Sales Co., Ltd. said: "In the new energy era, safety is still the most basic and core demand of users. Safety, especially the safety of the battery' big heart', is the primary factor affecting consumers' car purchase decision, and it is also one of the * * * characteristics for users to choose ARIYA ARIYA. "Adhering to the people-oriented electric drive, ARIYA ARIYA relies on Nissan's highest global standards and uses the full-link self-research capability of battery technology to condense the confidence of" quantity ",break users' battery safety anxiety and protect users' beautiful people, cars and lives.

As one of the few manufacturers with battery assembly lines, in order to firmly control the safety of batteries from the production source, the assembly and production of ARIYA ARIYA batteries are backed by the brand-new Renault-Nissan-Mitsubishi Alliance and the top intelligent, green and efficient digital benchmarking factory in China-Dongfeng Nissan Wuhan Factory, which ensures the safety of batteries, ultra-safe battery technology, intelligent management system and 3D real-time online visual inspection.

In the production and preparation of batteries, it is different from other manufacturers' direct OEM. Dongfeng Nissan insists on customizing batteries according to Nissan's global high standards, using customized dedicated lines for production, and 100% strict testing and screening to ensure high safety, long life and high density of batteries.

In the era of fuel vehicles, the engine is the heart of the car. A long-standing saying that "the key to Dongfeng Nissan's car is the engine" has become a distinctive label of Dongfeng Nissan. "On the new energy track, we hope to set a battery safety benchmark with ultra-safe batteries. When people talk about Dongfeng Nissan pure trams, they can blurt out that' Dongfeng Nissan's new energy vehicles are good, and the key is good battery'. " Chen Haocun said, "Dongfeng Nissan chose to do difficult and correct things. On the journey of self-research of battery technology, we have no hesitation. "

Not long ago, ARIYA passed the three rigorous tests of "high pressure flushing, four times national standard temperature shock and durable vibration" of China Automotive Technology and Research Center Co., Ltd. (hereinafter referred to as "China Automobile Center"), and successfully passed the battery safety challenge of China Automobile Center with the excellent results of "no water leakage, normal battery function, no internal and external structural damage, intact air tightness and no obvious attenuation of bolt torque". Hua Miao, an engineer of China Automobile Center, believes that battery safety is the core of new energy vehicle safety, and excellent safety performance is based on technical strength and advantages. Both the five-star safety rating in the previous European NCAP crash test and the three rigorous tests of China Automobile Center prove that the safety quality of ARIYA ARIYA is consistent all over the world.

ARIYA ARIYA's Nissan ultra-safe battery architecture adopts a nine-fold physical protection architecture. In passive battery safety protection, the integrated aluminum battery compartment adopts six reinforced aluminum column beams and a 25mm thick double-layer high-strength shell, which can improve the compression resistance of the battery pack and protect the internal batteries and modules.

In the battery compartment, the batteries are produced according to Nissan's global high-standard customized dedicated line, aerogel is installed between the batteries, and the dual-stack module has a unique double anti-collision bumper, and the wiring harness is accurately laid out to create the first line of defense for passive battery safety protection, which will nip the risk of battery short circuit, fire and explosion in the cradle.

The exterior of the battery compartment is made of 65,438+500 MPa ultra-high strength steel, and the protective diamond cover is reinforced with resin chassis armor. It has a unique 360-degree collapse protection space, and the side impact energy absorption is nearly twice that of C-NCAP standard, which constitutes the second line of defense for passive battery safety protection. All-round protection ensures that the battery compartment is intact and inviolable. ?

In terms of active battery safety protection, Nissan's self-developed full-working battery accurate management system, with the shortest time of 10 millisecond, accurately realizes real-time monitoring of more than 200 data and intelligently adjusts the battery working state; The industry-leading integrated liquid thermal management system for dry and wet separation can intelligently control the temperature according to environmental changes, so as to keep the battery in the best condition. It is worth mentioning that with the help of PTC heater in the battery management system, ARIYA ARIYA can realize the rapid heating of air conditioners, meet the needs of users for indoor heating in winter, and show ARIYA ARIYA's humanistic care for users.

In addition, ARIYA ARIYA also "checks" security through high-standard tests. In order to ensure the safety of use in various scenarios, ARIYA ARIYA battery has to go through many tests such as falling, drowning, freezing, fire and collision in the development and verification stage. The battery safety test is as high as 1 1 1, covering various types such as mechanical safety test, environmental safety test and electrical safety test.

It is precisely because ARIYA ARIYA has created a high standard safety line from development verification to production source; Nine-fold safety protection, efficient cooperation between software and hardware, to create an ultra-safe battery field, so that we are not afraid of the three major battery testing challenges of China Automobile Center, dare to confidently guard users' travel, and truly make users "safe and worry-free".

Dongfeng Nissan not only has strength and technology, but also has real sincerity. As of March 3 1 day, new car buyers can enjoy limited-time car purchase discounts. Aria Aria's long battery life version only costs 224,800 yuan, the long battery life top version costs 237,800 yuan, the high-performance four-wheel drive version costs 267,800 yuan, and the high-performance four-wheel drive top version costs 282,800 yuan. In addition, there are free basic maintenance, free car traffic for life, and two years of zero interest sharing benefits. At the same time, for the old users who have purchased ARIYA ARIYA, Dongfeng Nissan specially launched a customer-specific gratitude feedback activity, enjoying benefits with ARIYA life points equivalent to 5000- 10000 yuan, which filled the expectations of users and made ARIYA ARIYA's hospitality truly benefit every car owner.
