It is no exaggeration to say that many consumers still have a "crisis of trust" in electric vehicles. This is not because consumers are worried that the battery life of electric vehicles will not be enough, in fact, many consumers are not worried about endurance now, and there are many owners who drive electric vehicles to Sichuan and Tibet. What consumers are really worried about is the safety of electric vehicles. Although Tesla, Weilai, Lantu, BYD and other brands, they all claim that their new energy vehicles have higher safety. However, since the birth of electric vehicles, there have often been news of spontaneous combustion and even explosions, and Tesla and Weilai have naturally reported many times because of their models.
And in the recent period, Tesla, Xiaopeng, Weilai, BYD and other brands of electric vehicles, but also spontaneous combustion incidents, their influence once again fermented, so that consumers began to pay more attention to the safety of new energy vehicles. However, careful consumers may have found that at present, Lantu's Lantu FREE has not had a fire and spontaneous combustion accident, and it seems that in the price of 300,000, Lantu FREE is one of the safer electric vehicles. So, is Landu FREE really safe, and why has it not had spontaneous combustion or fire accidents so far? To answer this question, we have to look at the battery safety of Lantu FREE.
The fundamental reason why the battery will catch fire and explode is that in order to improve energy efficiency, car companies often choose electrode materials with more active chemical properties, which makes the endurance of electric vehicles increase, but it is also inevitable to reduce the safety of the battery pack. At present, the mainstream battery production level in the industry has reached the PPM level, that is, the safety efficiency of the battery cell is one millionth. At first glance, this data is very low, but this data is for a single battery, and on an electric vehicle, there is often more than one battery. Moreover, once a certain moment of battery failure and fire, it will directly drive other cells to catch fire together, eventually causing the vehicle to spontaneously combust. The "mica, amber" battery technology carried by Landu Auto for Landu FREE is a new technology designed around the instability of a single battery cell that causes the entire battery to catch fire.
In the "mica, amber" system, the "three-dimensional insulation wall" is integrated into the industry's first technology. The core principle of this technology is that the thermal insulation flame retardant material without thermal diffusion is wrapped on the outside of each cell, and if one cell fails to catch fire, it will not threaten other cells, fundamentally solving the problem of battery fire caused by cell instability. On this basis, Lantu is also equipped with a super liquid cooling system at the bottom of each cell, which can cool the battery cell and reduce the possibility of fire caused by overheating.
In addition to the "mica, amber" system and the "three-dimensional insulation wall", Landu FREE also has five layers of PACK security protection, which is mainly to improve the safety of the battery pack by increasing the body structural parts. These five layers of safety protection include the body itself, the safety frame of the battery pack, the optimized pressure transmission path, the deformation energy absorption structure, and the cell double insurance. In the event of a vehicle collision, the kinetic energy of the outside world is absorbed by these more robust body structures as much as possible, and the battery pack of the vehicle is not damaged as much as possible.
In addition, Landu FREE also has Landu exclusive cloud BMS, which is a set of power battery data analysis and management system. The advantage of this system is that it has a long life cycle, it can cover the whole life cycle of the vehicle, and can optimize the management ability of the chip in the car for the battery through independent learning and OTA upgrades, so as to ensure the health of the battery. In addition, this system can accurately warn of battery failure, and when a battery problem is detected, it can actively prompt the owner, which is also a detail that can improve safety.
Finally, Lantu FREE conducted rigorous safety tests including extrusion, collision, high temperature water and other rigorous safety tests in the battery safety test of the laboratory of China Automobile Center, and finally won the result of "no smoke and no fire" in the test. Through this test, we can also find that the battery safety of Lantu FREE is high, not on paper, Lantu has indeed made efforts in this regard, hoping to ensure the safety of users' travel. Therefore, although many electric vehicles frequently spontaneous combustion accidents, not all electric vehicles are unsafe.
