Dongfeng Nissan, as one of the few manufacturers with battery assembly lines, controls battery safety from the source of production. The assembly and production of ARIYA ARIYA batteries are backed by Renault-Nissan-Mitsubishi New Alliance and Dongfeng Nissan Wuhan Factory. The ultra-safe battery technology, intelligent management system and 3D real-time online visual inspection guarantee the safety and product quality of the batteries.
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.
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".
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 standards, aerogels are installed between the batteries, the dual-stacked modules have unique dual anti-collision bumpers, and the wiring harness is accurately laid out to create the first line of defense for passive battery safety protection and avoid the risks of battery short circuit, fire and explosion.
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".
