Sometimes I wonder, are today’s gangster movies and police movies a bit outdated? If all the fuel vehicles in the movie were replaced by new energy vehicles, would many plots and scenes be "subverted"? For example, the scene where a bullet hits the fuel tank and the car is surrounded by raging fire with a bang. If it were replaced by a new energy vehicle and the bullet hit the battery pack, wouldn't the scene be more explosive and exciting... .
I am just fantasizing about it. Unexpectedly, one manufacturer actually became serious about it. According to Aian's thinking, most current battery packs do have the possibility of deflagration after being impacted or punctured, and are no less harmful than gasoline deflagration. Therefore, they, in turn, researched and developed a series of batteries that are not afraid of impact or puncture. Technology - not even afraid of being penetrated by bullets. Naturally, Aian called this set of black technology "Magazine Battery 2.0".
Battery safety experiment with real ammunition
On March 30, at the magazine battery 2.0 launch conference, Aian boldly tested more than one gun in front of many professional media. Battery safety performance in extreme environments such as instantaneous short circuit of battery cells and explosive damage. Aian told us that this will be a real-life battery safety experiment. I didn't expect at all that the real guns and live ammunition were literally real guns and live ammunition.
Ean really used shooting to verify the safety of the magazine battery. The experimental results are very clear. There was no fire or explosion in the overall visual inspection of the magazine battery 2.0. When the casing was disassembled and inspected, 3 of the cells were completely damaged. After the battery pack was left standing, there was no fire or explosion during the process, and the voltage quickly dropped to zero. , the temperature gradually returned to normal and successfully passed the shooting test. Later, Aian analyzed for us the secret of the magazine battery 2.0 not catching fire or exploding at a technical level.
First, the magazine battery 2.0 adopts "ultra-stable electrode interface" technology. Through nano-ceramic materials with high stability and high heat resistance, Magazine Battery 2.0 greatly increases the toughness of the electrode interface; and the application of composite current collector materials can quickly collapse to form an open circuit when heat accumulates, avoiding continuous short circuits that generate high heat; In addition, the electrolyte of the magazine battery 2.0 is added with an oxidation-resistant flame retardant, which can quickly flame retardant after being activated by high temperature. The heating rate can be suppressed to less than 20%, avoiding the risk of instantaneous fire and combustion due to thermal runaway.
Second, Aion and China Aerospace Corporation have jointly developed phase change materials that can insulate and absorb heat. Compared with conventional thermal insulation materials, this new phase-change material can absorb heat more efficiently while maintaining a constant temperature, and the overall thermal insulation performance is greatly improved by 40%. Magazine Battery 2.0 uses a double-layer insulation system made of this new material, which insulates the top and bottom of the battery core at the same time. The overall insulation efficiency can be increased by 80%, and the temperature of the upper shell can be reduced by 75%, to the maximum extent. Ensure the safety of the occupants above the battery pack.
Thirdly, the magazine battery 2.0 also comes with a battery cell fire extinguishing system. Aian engineers cleverly used low-melting point alloys to form a fire extinguishing chamber. When the battery core undergoes thermal runaway, the fire extinguishing chamber fuses, and the thermally runaway battery core is quickly and accurately self-positioned, and the fire extinguishing agent is accurately sprayed onto the battery core in an instant. While absorbing heat and vaporizing, the inert gas formed by the fire extinguishing agent prevents the ignition and combustion of the battery cells. Combined with the thermal runaway gas emission treatment technology, the magazine battery 2.0 can eliminate sparks and 99.5% of PM10 in the exhaust.
Fourth, big data + AI, the cloud identifies battery faults. Based on Aion's full life cycle application data of more than 600,000 vehicles and 1,300TB, the sixth-generation cloud battery management system has greatly improved fault self-detection capabilities, including abnormal discharge, abnormal cooling, abnormal electrical connections, and hidden insulation faults. , the internal short circuit AI identification capability has reached 200Ω level, which is much higher than the risk line of 10Ω, which can be said to be "preventing trouble before it burns".
Why was Aian the one who fired the first shot?
When Aian fired this shot, although some people still think it was a violent marketing campaign, you have to deny that compared with the other two batteries in the control group that caught fire, the magazine Battery 2.0 has indeed withstood penetrating bullet fire; you also have to admit that Aian not only pays attention to the details of battery cell safety technology, but also has a broad vision and advanced layout on the electrification technology route, which makes it difficult for many peers Reach.
As early as 2011, Aian began research and application of electrification-related technologies. Unlike the usual "science and engineering men" who close their doors and work alone, Aian not only studies hard on his own, but also builds a "new energy circle of friends". Aian not only built its own battery trial production line, but also invested 4.96 billion yuan to establish an energy company, and invested 10.9 billion yuan to establish Yinpai Battery Technology Company. In addition, Aian also cooperated with Ganfeng Lithium Industry, Hanrui Cobalt Industry and other upstream raw material suppliers. The businessmen reached a strategic cooperation. It can be said that Aian has properly laid out the entire 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 echelon utilization.
Rome was not built in a day after all. Aian's magazine battery 2.0 technology cannot be achieved overnight. From the beginning of magazine battery 1.0 to the sales of more than 600,000 vehicles, Aian has accumulated a large amount of user data and experience while emphasizing safety, laying a solid foundation for the update and iteration of magazine batteries.
With the help of "Moments" and the support of the industry chain, the debut of Magazine Battery 2.0 is even more shocking. These conditions determined that Aian was more confident than other business partners to fire the first shot.
However, the magazine battery 2.0 technology is really shocking in terms of the safety of power batteries, but its specific performance still needs to be installed in the car and have hundreds of thousands of users and millions of users. Only actual vehicle verification of mileage can truly make consumers feel at ease. Among the models currently on sale by Aian, there are currently no models equipped with magazine battery 2.0 technology. The good news is that Aion's first model equipped with magazine battery 2.0 technology, the high-performance coupe Hyper GT, is getting closer to the launch date, let's wait and see.
Summary: For Aian, this battery safety test with live ammunition is a way of publicity that directly hits the pain points of consumers; more importantly, it becomes a way for Aian to move towards the next stage of goals. milestone. Since 12 years ago, Aian has been accumulating new energy technologies, reserving new energy talents, and insisting on taking an independent innovation route. In the field of new energy, in addition to the magazine battery series, Aion has also released core three-electric technologies such as super-speed batteries, sponge silicon negative electrode batteries, microcrystalline lithium iron batteries, and quark electric drives. Aian's strong technical reserves in the field of new energy not only enhance its overall competitiveness, but also provide consumers with more peace of mind and comprehensive protection.
