Charging spontaneously ignites and collides with fire. We often brush videos on social platforms such as short videos, which makes ordinary consumers have doubts about new energy vehicles. Therefore, a qualified new energy product, safety is not only its core appeal, but also its foundation. As the heart of electric vehicles, the safety of batteries bears the brunt, which is also the most direct factor that determines whether consumers decide to buy a car. ARIYA ARIYA, based on Yunxiang professional pure electric platform, has broken consumers' concerns about battery safety while meeting Nissan's highest global standards through self-research of battery technology.
Self-research of battery full link
The fewer suppliers of an automobile component, the higher the matching degree and stability of its products. Dongfeng Nissan is one of the few manufacturers with its own battery assembly line. The assembly and production of ARIYA ARIYA battery comes from Dongfeng Nissan Wuhan factory, relying on intelligence, high standards and digitalization to build a battery safety fortress. In battery manufacturing, Dongfeng Nissan adopts customized special line for production, and 100% is strictly tested and screened, thus ensuring high safety, long life and high density of batteries. At the same time, the factory's intelligent management system, 3D real-time online visual inspection and other layers of protection can also ensure the safety of batteries and the quality of products.
The reason why Dongfeng Nissan has made great efforts to build a cost-effective battery technology on the road of full-link self-research is to set a safety benchmark in the circle through reliable batteries and electronic control. In the future, when people talk about Dongfeng Nissan's pure electric vehicles, they can give people the impression that "Dongfeng Nissan's new energy vehicles are good, and the key is good battery."
Wading, vibration and temperature changes through severe challenges.
The safety of technology and production process is guaranteed. How to verify the reliability when using it? To this end, Dongfeng Nissan ARIYA ARIYA conducted an impact test of "high pressure flushing, durable vibration and four times the national standard temperature" at the China Automobile Center. High-pressure washing is to simulate driving in rain and snow, and the battery is wet by the water splashing from the tires of the same car or the opposite car. Persistent vibration is the impact of the vehicle on the battery when driving on the bumpy road for a long time. Four times the national standard temperature sounds the hardest to understand. For example, when we drive in winter and the outdoor temperature is below zero, we go home and park our car in the basement of the community to simulate the image of the battery caused by the temperature difference between inside and outside. And four times the national standard temperature change is equivalent to moving the electric car driving in Mohe to Xishuangbanna at once.
The test results passed the challenge of the safety center of China Automotive Battery with the excellent results of "no water leakage, normal battery function, no internal and external structural damage, good air tightness and no obvious attenuation of bolt torque". In fact, it's not just battery safety. Aria Aria had previously obtained a five-star safety score in the European NCAP crash test. As the saying goes, to set a benchmark, safety and quality must come down in one continuous line to ensure global consistency.
Before Nissan paved the way, after ARIYA Aria carried the change. Nissan's 76 years of pure electric technology and more than 25 years of experience in battery development and manufacturing have gradually carried forward the quality reputation of "2 1 100 million kilometers battery 0 major safety accident". Born in the professional pure electric platform of Nissan Global Cloud Image, Aria Aria is equipped with highly integrated self-developed three-electricity technology to redefine the new battery safety standard in the field of new energy vehicles with Nissan ultra-safe battery architecture.
Nine-fold security protection is more practical
Let me talk about the passive safety protection highlights of the battery. The integrated aluminum battery compartment adopts six reinforced aluminum column beams and a 25mm thick double-layer high-strength shell, which can improve the compressive strength of the battery pack and protect the internal batteries and modules.
Integrated aluminum battery compartment
In the battery compartment, in addition to high-standard customized production, aerogels are installed between batteries. Its double-layered module has a unique double anti-collision bumper, and the wiring harness layout is accurate and standardized, creating the first line of defense for passive battery safety protection. Effectively avoid battery short circuit, fire, explosion and other security risks.

Outside the battery compartment, the whole body is covered by 1500MPa ultra-high strength steel and reinforced resin chassis armor. The impact energy absorption of side impact in 360 collapse protection space is nearly twice that of C-NCAP standard. This is the second line of defense for passive battery safety protection.

After talking about passivity, let's talk about the active safety protection of batteries. Thanks to the self-developed full-condition battery accurate management system, the shortest time is 10 millisecond, which can accurately monitor more than 200 items of data in real time and intelligently adjust the working state of the battery. Dry-wet separation integrated liquid thermal management system can intelligently control the temperature according to environmental changes, so that the battery is always in the best state. In addition, ARIYA ARIYA also has PTC heat pump air conditioning, so the heating in the car will not be greatly cut off in winter.
In fact, in the verification stage of R&D, ARIYA ARIYA's battery has experienced many tests such as falling, drowning, freezing, fire and collision. 1 1 1 test, covering mechanical, environmental, electrical safety and other test types.
The official time-limited reduction of pet powder is 60 thousand yuan.
Welfare stays last. From now until March 3 1 day, Ariya Ariya will reduce its official salary by 60,000 yuan in the form of government subsidies. All dealers' special stores are the same. After all, they are all directly operated by manufacturers, and there is no question of who has more discounts and who has less discounts. Long battery life version is 224,800 yuan, long battery life top version is 237,800 yuan, high-performance four-wheel drive version is 267,800 yuan, and high-performance four-wheel drive top version is 282,800 yuan. Free basic maintenance, free car traffic for life, zero interest for two years, and also a time-limited benefit.
