Indisputable fact: whether it's political leadership or internationalization trend, new energy vehicle lineup is getting stronger and market attention is getting higher and higher. In ranks of energy vehicles, involution between enterprises and products is becoming more serious, and has also become a recognized phenomenon inside and outside current industry of new energy market.
However, how can market for new energy vehicles "volume"? As drive motor technology continues to improve, more and more manufacturers can label their products as "high performance", and acceleration from 100 kilometers to 4 seconds or even 3 seconds as a "club"; when supplier system gets bigger, four-wheel drive system, air suspension or full-fledged audio-visual equipment of world-famous brands are all added to new body. Almost every car has a very significant height of configuration. In situation of volume, there are not many effective ways.
Dongfeng Nissan has taken a path that users cannot see because of external strength of product to overcome the industry's limitation of battery safety.
Battery safety is undoubtedly top concern of any new energy vehicle user, especially when endless new energy vehicles are suspected of spontaneous combustion, leakage, or even more serious accidents due to battery safety. Energy cars have also left seeds of doubt. in hearts of potential users because of hidden dangers associated with battery safety, which makes users doubt choice of car.
In order to allay user concerns about battery safety, Nissan, with 76 years of pure electric technology experience and over 25 years of battery R&D experience, has launched global vehicle model ARIYA (Dongfeng Nissan Ariya) under brand wave of international new energy. With regard to battery safety, he demonstrated exclusive right to speak about Nissan brand.
Production line safety, customization + independent research, core is in your hands
The battery used by Dongfeng Nissan Arriere is manufactured at Dongfeng Nissan's Wuhan plant, which is also one of smart and efficient digital benchmark factories built in China under new Renault-Nissan-Mitsubishi alliance. one of few battery assembly production lines in industry, Arieya battery assembly is controlled by Dongfeng Nissan brand itself, and process standards, management system and quality control standards are strictly controlled by company itself. This is different from other companies that use outsourcing. The form of battery assembly by car companies is fundamentally different.
Although battery cells for Arrow come from Ningde Times, they are not a full Ningde Times OEM. Instead, Dongfeng Nissan and Ningde Times collaborated to set up a battery production line. The whole process of testing and verification is completed. Dongfeng Nissan took part in its own participation. It can be said that, starting from source of battery, Dongfeng Nissan understood essence of battery safety.
The structure is safe, and battery is "dressed" with 9 layers of "physical armor"
The Arial battery uses a nine-level physical protection structure. In terms of passive battery protection, it uses a built-in aluminum battery case, with six aluminum columns and beams cast inside, and body adopts a double-layer high-strength case. 25mm thick. Housing assembly, high-strength protection of internal batteries and modules.
The two-tier module in cabin has an independent shock-proof bumper, airgel is installed between cells, and is complemented by precise location of wiring harness, which effectively guarantees absence of short circuits, fires, explosions and other serious risks. takes place in battery compartment.
The battery protection cover is made of 1500MPa high-strength steel, which covers chassis armor and leaves a 360° anti-collapse space. The absorption of impact energy in a side impact is almost twice as high as in C-NCAP standard. which is passive safety of battery. The “second line of defense” of protection provides comprehensive protection to ensure that battery compartment is not damaged and untouched.
In terms of active battery protection, precise thermal management system monitors more than 200 real-time data in as short as 10 milliseconds and intelligently adjusts battery's operating condition. and wet separation can monitor temperature in real time, keep battery working temperature at optimum level.
In addition, in order to ensure safety of use in various scenarios, Arrow batteries must pass many tests during development and verification phase, such as dropping, immersion in water, freezing, fire, collision, etc. The battery safety test reaches 111 points , including mechanical safety test, environmental safety test, electrical safety test and other types.
It is precisely because Dongfeng Nissan has built a high standard protection line for Arriere from development and verification to source of production, a strong battery safety structure design, and software and hardware protection capabilities together and effectively, so that Dongfeng Nissan Arriere can handle with Chinese cars. Technology Research Center (China Automotive Center) has more confidence in battery safety test, and results are very satisfactory: after three high-pressure washing tests, 4 times that of country. standard temperature shock and strong vibration, Aria battery performance remains normal, air tightness is intact, there is no structural damage inside and outside, and it passed test without problems.
Battery safety is product feature that most worries users, but it cannot be detected by user's short-term observation. Dongfeng Nissan Aria is rooted in this and strives for excellence. As before, company in China Market and even international automotive market is engaged in pure electric vehicles. Nissan has a reputation for quality with "21 billion battery miles and zero major accidents." Yansandian's technologies and concept of reliable battery design will provide a strong guarantee of safety for most vehicles. users, and Dongfeng Nissan will definitely have a lot to do in new energy market in future.
