I was just imagining things. Unexpectedly, a manufacturer actually got serious. According to Ai 'an's thinking, most of the current battery packs do have the possibility of deflagration after being punctured by impact, which is no less harmful than gasoline deflagration; Therefore, in turn, they have developed a series of battery technologies that are not afraid of impact and breakdown-even by bullets. Naturally, Ian called this black technology "Magazine Battery 2.0".
Safety experiment of live ammunition battery
On March 30th, at the press conference of Battery 2.0 magazine, in front of many professional media, Ai 'an boldly tested the battery safety performance of several batteries in extreme environments such as instantaneous short circuit and burst damage. Ian told us that this would be a safety experiment of live ammunition batteries. I don't know if live ammunition is real ammunition.
Ian really used photography to verify the safety of the magazine battery. The experimental results are very clear. The magazine battery 2.0 does not catch fire or explode visually. Disassemble the shell and check whether the three batteries are completely damaged; After the battery pack stood still, there was no fire or explosion in the process, the voltage quickly dropped to zero, the temperature gradually returned to normal, and the shooting test was successfully passed. Later, on the technical level, Ian analyzed the secret that the magazine battery 2.0 did not catch fire or explode.
First of all, the magazine battery 2.0 adopts the "ultra-stable electrode interface" technology. Through the nano-ceramic material with high stability and high heat resistance, the magazine battery 2.0 greatly increases the toughness of the electrode interface; The application of composite current collector material can quickly collapse to form an open circuit when heat is accumulated, so as to avoid high heat caused by continuous short circuit; In addition, the anti-oxidation flame retardant is added to the electrolyte of the magazine battery 2.0, which can quickly flame retardant after high-temperature activation, and the heating rate can be suppressed below 20%, thus avoiding the risk of fire and combustion when the heat is out of control.
Secondly, AEON and China Aerospace jointly developed a phase change material which can insulate heat and absorb heat. Compared with conventional thermal insulation materials, this new phase change material can absorb heat more efficiently while keeping the temperature unchanged, and the overall thermal insulation performance is greatly improved by 40%. Magazine battery 2.0 adopts a double-layer heat insulation system made of this new material, and simultaneously insulates the top and bottom of the battery cell. The overall heat insulation efficiency can be improved by 80%, and the temperature of the upper shell can be reduced by 75%, which ensures the safety of passengers above the battery pack to the greatest extent.
Third, the magazine battery 2.0 also comes with a battery fire extinguishing system. An engineer skillfully composed a fire extinguishing room with low melting point alloy. When the battery is out of thermal control, the fire extinguishing chamber melts, the battery with thermal control can quickly and accurately locate itself, and the fire extinguishing agent can be sprayed to the battery instantly and accurately. At the same time of endothermic gasification, the inert gas formed by the extinguishing agent prevents the battery from burning. Magazine battery 2.0 combined with thermal runaway gas emission treatment technology can eliminate sparks and 99.5% PM 10 in waste gas.
Fourth, big data +AI, cloud identification battery failure. The sixth generation cloud battery management system has greatly improved the fault self-detection ability, including abnormal discharge, abnormal heat dissipation, abnormal electrical connection and hidden insulation fault, based on the application data of more than 600,000 vehicles in Ai 'an, 1 300 TB in the whole life cycle. The AI recognition ability of internal short circuit has reached 200Ω level, which is much higher than the risk line of10Ω, which can be described as "impossible to prevent".
Why did Ian shoot the first shot?
Ian shot him. Although some people still think that this is an "out of line" violent marketing, you have to deny that compared with the other two burning control batteries, the magazine battery 2.0 really survived the penetrating bullet shooting; You also have to admit that Ai 'an not only pays attention to the details of battery safety technology, but also has a broad vision and advanced layout in the electrification technology route, which is beyond the reach of many peers.
As early as 20 1 1, the research and application of electrification related technologies began in Ai 'an. Unlike the "science man" who usually builds a car behind closed doors, Ai An not only painstakingly studies himself, but also starts a "new energy circle of friends". Ai 'an not only built its own battery trial production line, but also invested 4.96 billion yuan to set up an energy company and 654.38+009 billion yuan to set up a silver battery technology company. In addition, Aian has also reached strategic cooperation with upstream raw material suppliers such as Ganfeng Lithium Industry and Han Rui Cobalt Industry. It can be said that the whole industrial chain of upstream raw materials, power battery technology research and development, power battery manufacturing, waste battery recycling, new energy storage and transportation, deployment and cascade utilization has been properly laid out.
After all, Rome was not built in a day. Ian's magazine battery 2.0 technology is not achieved overnight. From the magazine battery 1.0 to the vehicle sales of more than 600,000 vehicles, on the premise of emphasizing safety, Aian has accumulated a huge amount of user data and experience, laying a solid foundation for the magazine battery update iteration. With the support of "friends circle" and industrial chain, the appearance of magazine battery 2.0 is even more shocking. These conditions determine that Ian is more confident than other friends to shoot the first shot.
However, magazine battery 2.0 technology is really shocking in terms of the safety of power batteries, but the specific performance still depends on the verification of hundreds of thousands of users and millions of miles of real vehicles after actual loading, so that consumers can really rest assured. Among the models currently on sale in Ai 'an, there are no models equipped with magazine battery 2.0 technology for the time being. The good news is that the high-performance coupe Hyper GT, Ai 'an's first model equipped with magazine battery 2.0 technology, is getting closer and closer to the market date, so let's wait and see.
Summary: This battery safety test with live ammunition is a publicity method that directly hits the pain points of consumers for Ai 'an. More importantly, this has become a milestone for Ai 'an to move to the next stage. Since 12, Aian has been accumulating new energy technologies, reserving new energy talents and adhering to the independent innovation route. In the field of new energy, in addition to magazine battery series, Ai 'an has also released core three electric technologies such as ultra-fast battery, sponge silicon negative plate battery, microcrystalline lithium iron battery and quark electric drive. Aian's strong technical reserves in the field of new energy not only enhance the overall competitiveness, but also bring more peace of mind and comprehensive protection to consumers.
