Introduction: With the support of Dongfeng Motor Corporation’s over 50 years of car-making technology and superior resources, Landtu Motors has achieved multiple accomplishments at an extremely fast pace. Especially in battery safety and high-voltage platform and fast-charging technology, which can solve the problem of pure electric new energy vehicles being constrained by battery safety and range anxiety.
On September 26, based on high-frequency accident scenarios provided by the Ministry of Public Security’s Traffic Management Bureau, and certified by China Automotive Technology and Research Center, the Landtu FREE successfully challenged the world’s first public test of electric vehicle’s bottom collision after being submerged in water. The test simulated a scenario of heavy rain flooding and bottom collision after the electric vehicle was submerged in water. The final test result was “no smoking, no fire, no explosion, no water ingress”.
As we all know, safety has always been the first rule of Landtu’s car-making. By passing the world’s first public test of electric vehicle’s bottom collision after being submerged in water, Landtu FREE has once again successfully surpassed the safety testing standards in the industry. As early as September 17 this year, Landtu succeeded in conducting battery safety tests using a battery pack superimposed test method, which achieved a compression twice the national standard, a simulated collision twice the national standard and a high-temperature water spraying test with the highest 9K level of protection.
Making cylindrical batteries into non-flammable battery packs, only Landtu has achieved it, and even Tesla hasn’t
In the era of electric vehicles, battery cells can be said to be the core components of electric vehicles, just like transmissions, but the number of host factories capable of producing battery cells is very small. Currently, most automakers purchase mature battery pack solutions from battery manufacturers. Landtu is one of the car makers that independently develops battery packs, making cylindrical batteries into non-flammable battery packs, which even Tesla, whose core is cylindrical batteries, has not achieved, proving that Landtu’s battery pack design level is not low.
At Landtu’s press conference, there was a PPT page like this: according to Landtu’s observation, they currently classify the best car makers into three categories: those with independently developed battery systems, those with pure outsourcing, and those with independently developed batteries. However, Landtu belongs to the first category of independently developed battery systems. So why did Landtu go to such great lengths to develop a battery system on its own? In fact, Landtu’s core demand is only one thing: safety.
Landtu CEO Lu Fang, Ph.D., said: “Safety has always been the first rule of Landtu’s car-making. For electric vehicles, battery safety is the ‘real safety’. Landtu Motors does not produce battery cells, but focuses on solving battery system safety. Landtu’s pioneering efforts in submersion and bottom collision tests are designed to use the most stringent tests to verify the safety performance of the entire vehicle, and to break through the new heights of electric vehicle safety standards. “It is worth mentioning that, as LanTu Automotive stated, users may face multiple and overlapping damages in various aspects such as the three-electricity system and the vehicle structure during actual use, not just piercing of the battery pack, as well as collision, flooding, etc. In actual use, LanTu ultimately succeeded in the “all-scenario accident stacking” test challenge. As we all know, 250mm of rainfall in 24 hours is a heavy rainstorm, and this time LanTu successfully challenged 600mm of flooding, which is 6 times the national standard. It is reported that the national standard is only 100mm in depth.
China Automotive Technology Research Center experts believe that LanTu Automotive’s pioneering challenge of the “all-scenario accident stacking” test has practical and realistic significance.
This means that we can rest assured of the water safety of LanTu FREE. At the same time, with the five-layer safety protection technology of PACK and the exclusive cloud BMS technology, it can prevent the battery cell from being impacted or squeezed. In the inevitable case, it can also control the battery from catching fire or exploding through an explosion-proof valve set on the bipole. It can also add an “online security” to LanTu’s battery pack, which will alert users through an APP if the battery is abnormal. With these technologies, even if LanTu FREE is flooded with 600mm, and the bottom of the vehicle is in serious collision, there are no battery safety issues. Even the leading electric vehicle industry giant, Tesla, has not reached this level of technology.
LanTu’s understanding and implementation of electric vehicle technology leads other new forces by a number of steps.
It can be said that LanTu redefines the safety standards of new energy vehicle batteries. Along with leading battery system technology is LanTu’s continually growing research and development team. Currently, LanTu Automotive’s official information shows that LanTu has built up a young but experienced battery development team. They come from all over the world, over 60% have master’s or doctoral degrees, many of whom have long served at more than 20 well-known companies such as CATL. There are also young people who have returned from studying in the United States, Britain, and Germany. This fully verifies that technological innovation is the core competitiveness of enterprises. In the “new force of car-making” track, as far as LanTu’s understanding and implementation of electric vehicles is concerned, other car companies have been left behind by LanTu. Each progress and breakthrough in technology will affect the entire new energy industry.As for Landtu Automobile itself, Landtu adopts a fully direct-selling model to reach customers and create a warm experience. According to Pacific Auto Report, as of the end of 2021, Landtu Automobile will establish over 50 direct sales channels across the country, covering 20 core cities, and providing customers with products and services that are “worth the money, trustworthy, regret-free to buy, worry-free to use, empowering for life, and friendship-enhancing”. Landtu is also reserving and commercially deploying more cutting-edge battery technology, while calling on consumers to trust the strength of the “national team”.
It is worth noting that just under a day after completing the water-wading and low-speed rear-end collision test, Landtu once again made a heavy announcement about an 800V high-voltage platform and 800V supercharging technology. This technology can achieve 400 kilometers of range in just 10 minutes of charging, which has brought new impetus to the development of the new energy vehicle industry. Currently, in order to solve the anxiety of electric vehicle owners about power supplements, some car manufacturers are trying to build private charging stations, such as Tesla and XPeng, or directly swapping batteries like NIO. Landtu’s idea is to create a high-voltage platform to shorten charging time. With the maturation of SIC technology and cost reduction, it is expected that the 800V platform will surpass private charging and battery swapping in resolving users’ anxiety about power supplements.
Compared to other new energy vehicle companies, as China’s “new car-making force”, Landtu has not been around for a very long time, having been established in 2018 as a high-end intelligent electric vehicle technology company. However, with the support of Dongfeng Corporation’s over 50 years of expertise and resources, Landtu Automobile has achieved many accomplishments at an extremely fast pace. Particularly, Landtu’s battery safety and high-voltage platform as well as fast charging technology can overcome the limitations of battery safety and range for pure electric new energy vehicles. Landtu’s proprietary technology has also won honor for Chinese brands and new forces.
