Xin Yu, general manager of Dongfeng Nissan Automobile Sales Co., Ltd. said: "For users, the demand for design, performance and technology varies from person to person. Safety, especially the safety of the battery' big heart', is the primary factor affecting their car purchase decision, which is one of the commonalities of their choice of ARIYA ARIYA." As the pioneer of Dongfeng Nissan's new energy era, ARIYA ARIYA returned to the core of users' concern, relied on Nissan's highest global standards, and used the full-link self-research capability of battery technology to break users' battery safety anxiety and consolidate the long board of safety value.
Self-research of battery full link, achieving "big heart" of safe battery
Safety begins with the nuclear "core". Under the highest standards of Nissan in the world, the customized, specialized and self-produced battery technology route has brought ARIYA confidence from the manufacturing system.
As one of the few manufacturers with battery assembly lines, Dongfeng Nissan builds an absolute fortress of battery safety with high standards of intelligence and digitalization. In order to firmly control the safety of the battery from the production source, the assembly and production of ARIYA ARIYA battery relies on the brand-new Renault-Nissan-Mitsubishi alliance and Dongfeng Nissan Wuhan factory, the top intelligent, green and efficient digital benchmark factory in China, with ultra-safe battery technology, intelligent management system, 3D real-time online visual inspection and other layers of protection to ensure the safety and product quality of the battery.
In terms of battery production, unlike other manufacturers' direct OEM, Dongfeng Nissan insists on customizing batteries according to Nissan's highest global standards, using customized dedicated lines for production, and 100% strict testing and screening to ensure high safety, long life and high density of batteries.
Xin Yu said: "We hope to set a battery safety benchmark with ultra-safe batteries. When people talk about Dongfeng Nissan pure trams, they can blurt out' Dongfeng Nissan new energy vehicles are good, and the key is a good battery core'. This powerful label carries our simplest vision, that is, every trip of users is a fulfillment of safety commitments. "
Nine-fold security protection, guarding the lifeline of users
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".
Battery safety is the core of new energy vehicle safety, and excellent safety performance is based on technical strength and advantages. Huang, deputy director of the new energy development department of the new technology branch of the technical center of Dongfeng Nissan Passenger Car Company, said: "There is no shortage of good products in the market now, but good products are not necessarily good products. Dongfeng Nissan's product development principle is to adhere to the bottom line of customer safety and make products with the highest development standards. " 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.
As a masterpiece of Nissan's technology, ARIYA ARIYA has inherited Nissan's 76-year pure electric technology and more than 25 years' experience in battery research and development, and inherited the quality reputation of "265,438+0 billion kilometers of battery 0 major safety accident". Relying on the cloud image of Nissan's top professional pure electric platform, Ariya has highly integrated the self-developed three-electric technology, and redefined the new battery safety standard with Nissan's ultra-safe battery architecture.
ARIYA ARIYA Nissan's ultra-safe battery architecture adopts a nine-fold physical protection architecture to build a super battery security domain with "soft and hard integration, both offensive and defensive, and internal and external coordination". In terms of passive battery safety protection, ARIYA ARIYA repairs both inside and outside, building a solid defense line for battery 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 compressive strength 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".
Intimate and worry-free service opens a new era of user experience.
