Therefore, for the research of electric vehicles, Nissan has been constantly iterating in technology, especially in the field of safety. Even from 20 10, the first mass-produced electric vehicle (leaf wind) was launched, keeping the safety record of 2 10/000 million km. Even ARIYA, which went on the market last year, uses high-standard batteries, and even passive protection is relatively higher than that of electric vehicles of the same price. So why should Nissan gamble on safety?
First, Japan's new energy breakthrough.
At the beginning of the Millennium, in order to respond to the requirements of global energy conservation and emission reduction, Japanese and German departments, as the top automobile departments, both took out their own dominant technical directions. Japan chose the direction of hybrid technology, and Germany chose the direction of diesel technology. At present, the direction of diesel is obviously wrong, and Volkswagen diesel exhaust valve has been judged as a dead end in the direction of diesel technology. Are Japanese hybrids really invincible?
Obviously not, it's a Japanese hybrid. In the final analysis, it is THS hybrid technology led by Toyota. At present, it has developed to the fourth generation, and the average fuel consumption of compact cars can be controlled at 4 liters. However, in the domestic market where electricity is the main development technology of new energy, Toyota's THS hybrid technology is obviously no longer popular, and hybrid power has become the shackles of Japan's future new energy.
In order to keep up with the electrification progress of the two major automobile markets in China and the United States, Toyota announced a comprehensive electrification transformation on 202 1, and Honda also carried out electrification transformation. As the brand with the deepest electric technology in Japan, Nissan can even launch pure electric vehicle ARIYA on behalf of leading Japanese car companies, among which safety has become the top priority of Nissan's electrification.
In China, intelligence is regarded as one of the propaganda points of electric vehicles, but the importance of safety is largely ignored. Many brands promote the integration technology of body and chassis, which integrates the battery into the chassis. In the case of extreme collision, it is likely to damage the battery pack and cause fire. Most of the safety problems of trams are caused by batteries, so it is extremely important to control the safety of batteries.
Nissan has created nine safety protections in the battery safety part of ARIYA, which can better ensure its safety, ensure ARIYA's anti-collision, not high temperature, and quickly disperse at high temperature. Among them, in the field of active safety, the liquid cooling system with dry and wet separation inside the battery compartment can disperse the heat evenly as quickly as possible, and the accurate management of the battery under all working conditions can better monitor each battery cell.
Nissan is also generous in the passive field. Six high-strength aluminum beams are used as battery case protection, and three beams and two longitudinal beams with 1500 MPa in the floor are used to protect the battery case safety of ARIYA at all times. ARIYA's front frame has more space for collapse protection, and the integrated aluminum battery protection cover protects the side from impact. On the other hand, double stacked modules can bring higher space utilization, allowing ARIYA to accommodate 90kWH super battery pack.
In addition, for the safety of the battery pack at the bottom of the electric vehicle, Nissan even installed a reinforced resin cover to prevent the impact of foreign objects at the bottom and form a soft and hard double-layer protection with the battery compartment.
Therefore, safety has become the most eye-catching breakthrough of Japanese new energy, and it is also the most easily overlooked demand of the two new energy markets in China and the United States.
Second, the demand changes of the mainstream population.
When the domestic market began to subsidize new energy sources a few years ago, the mainstream people were mainly a few early adopters, and their enthusiasm for new technologies was negligible. Therefore, the ultimate intelligence and technology became the mainstream demand of new energy users at that time.
However, with the participation of mainstream brands and the sharp increase in the number of users, diversified needs have become very important. New energy vehicles are no longer limited to how many large screens and radars there are, but pay more attention to the safety of trams or the convenience and humanization of use. Moreover, the spontaneous combustion of electric vehicles has greatly hindered the development of electric vehicles, and the reaction time left to users from overheating to fire is very short, so safety requirements have become particularly important.
Security requirements are like "1" in a series of numbers, and other requirements are "0" behind. Without the "1" in front, all the numbers behind are impossible to talk about. Therefore, traditional brands including Nissan, Volkswagen, Toyota and Honda all put forward higher requirements for battery safety. Even within Nissan, there is a slogan "I would rather sacrifice battery life to ensure battery safety". Traditional brands are catering to people's more needs, not limited to intelligence and technology.
Third, the technical precipitation of daily battery.
As mentioned above, after 76 years of electric technology precipitation, Nissan knows more about batteries than the new forces. Even earlier, Nissan had its own dedicated battery factory "Vision Power". When Nissan provided batteries for Leaf, it chose a safer chip battery structure, with a larger overall area and stronger heat dissipation capacity. After selling more than 600,000 blades, there is still no fire caused by spontaneous combustion.
It is precisely because Nissan has a large number of battery usage data that it is different from other brands in the choice of battery formula. And contemporary Ampere Technology Co., Ltd. specially customized a higher standard battery production line. The formula is not the traditional NCM523 battery, but the higher density NCM8 1 1 battery.
In the case that many brands have retired NCM8 1 1 batteries, Nissan does the opposite and adopts higher active and passive protection to keep the batteries in the best use state.
Write it at the end of the sentence
Nissan ARIYA is an important vehicle for Japanese to break through the new energy gap, which shows that Japanese people have a more important consideration in the choice of new energy, that is, safety. The new forces are still under the wave of intelligent and scientific volume. The volume safety, humanization and comfort of traditional brands are all necessary for the most mainstream new energy users. Will it be your new choice to return to product strength and give the tour guide Ariya a limited-time discount of 224,800 yuan?
