For a long time, the problem of endurance has been a problem that plagues the development of pure electric vehicles, but now the pure electric vehicle model with a cruising range of more than 1,000 kilometers has been mass-produced by a Chinese automobile company, that is, GAC Aion LX PLUS.
As GAC Aeon's latest flagship SUV model, the AION LX Plus can be said to represent the brand's highest level of technology. 1008km/h, 2.9s acceleration from 100km/h, equipped with the second generation of intelligent zoom lidar, ADiGO 4.0 system... At present, there does not seem to be any mass-produced pure electric vehicle that can be directly benchmarked with the AION LX Plus.
Of course, this series of subversive data will inevitably attract voices of doubt. Today, Brother Rumble will talk about what cutting-edge black technology is used behind AION LX Plus? Are these black technologies reliable?
The mystery of 1,000 km endurance: sponge silicon anode chip technology
First of all, I believe that everyone is most concerned about the AION LX Plus leading the industry several positions of 1008km endurance, how is this achieved? How technically reliable is it?
At present, the lithium battery anode material on the market is mainly graphite, which has the advantages of low production cost of mature preparation technology, but its theoretical specific capacity is only 372mAh/g, which largely limits the upper limit of lithium-ion battery capacity, so Aean's eyes are on the silicon-based anode with a higher gram capacity (4200mAh/g).
But in fact, the silicon-based anode will expand in the process of combining with lithium ions, which is a fatal injury to the densely laid out automotive power battery pack, so silicon anode batteries are rarely used in the field of electric vehicles.
Gac Aean's sponge silicon anode chip battery technology has overcome this problem very well, combining nanocomposite silicon technology, binder technology with self-healing function, gradient conformity coating technology, etc.
Among them, the nano-composite silicon technology controls the silicon material at the nanoscale, while its surface is covered with a protective layer to minimize the volume expansion during the silicon-based negative electrode reaction; the binder technology of self-healing function and the gradient conformity coating technology are the means to maintain the structural stability of the negative electrode sheet.
In short, GAC Aean sponge silicon anode plate battery technology is like the essence of Tai Chi to soft Kegang, the silicon anode inside the battery is designed as soft and elastic as a sponge, which can dissolve the expansion and contraction of silicon in the process of charging and discharging, prevent rupture, and at the same time can absorb water like a sponge, with super energy storage capacity.
From the perspective of the battery equipped with AION LX Plus, the energy density reaches 205Wh/kg, the capacity reaches 144.4kWh, and the comprehensive working range of CLTC reaches 1008km. Not only that, thanks to the combination of more than 50 patented technology groups such as nanotechnology, the cell capacity of sponge silicon anode chip batteries has increased by 25%, the cell volume has been reduced by 20%, and the weight has been reduced by 14%. This also allows the AION LX Plus equipped with a sponge silicon anode chip battery to not change much in the overall vehicle weight.
In general, the 1008km endurance of AION LX Plus is indeed amazing enough, but its actual performance still needs to be followed by the actual test experience, if the actual endurance can reach more than 800km after the discount, it is still very worth looking forward to. On the other hand, AION LX Plus still has many difficulties to overcome, the most important of which is undoubtedly the capacity and cost of this new type of battery, which is also doomed to be difficult to install on low-end models.
The top not only has battery life, but also high performance + high intelligence
The 1008km endurance is only a highlight of the more eye-catching AION LX Plus, aside from the super endurance, this car can still represent the top level of domestic new energy vehicle technology.
The official 0-100km/h acceleration time of the AION LX Plus is only 2.9 seconds, comparable to the recognized "ceiling" Tesla Model S/X Plaid for mass-produced electric vehicles.
This is mainly due to the world's first high-performance two-speed dual-motor "four-in-one" integrated electric drive equipped with AION LX Plus, of which the four-wheel drive high-performance version is also equipped with a front-axle motor, forming a three-motor power system, with a peak power of 540kW and a wheel end torque of 6100N·m after deceleration and twisting. And due to the high degree of integration of the electric drive system, its comprehensive drive efficiency is more than 90%, which further optimizes the dynamic performance and energy consumption performance.
It should be noted that the 2.9 seconds to break the hundred and 1008km endurance are actually from the four-wheel drive high-performance version and the rear-drive long-endurance version of the two different configuration versions.
If the long endurance and high performance of the AION LX Plus are not enough to stand on the top, then what about 3 lidars?
The AION LX Plus will feature the industry's largest 35 high-performance sensing hardware, including three second-generation solid-state lidars on top of the roof and on both sides of the front wheels. It can achieve a cross coverage field of view of 300 °, a dynamic adjustment of the environment perception refresh rate of 10 to 30 Hz, a dynamic adjustment of vertical resolution of 0.2 to 0.05 °, and a maximum detection distance of 250 meters.
Based on the 200TOPS high-computing power intelligent driving calculation platform, it can be competent for high-speed, urban road navigation driving assistance, and can also realize over-the-horizon summoning parking.
In terms of smart cockpit, AION LX Plus is equipped with a 7nm 8-core Qualcomm 8155 cockpit chip, with the third generation of Qualcomm Snapdragon flagship digital cockpit, equipped with IBCM non-sense start new AR real-life navigation, DMS+OMS cockpit monitoring and other intelligent configurations.
In addition, the intelligent IoT system has also been upgraded to ADiGO 4.0, which was the first to experience it, the UI design is simple and smooth and easy to use, the speech semantic recognition function is accurate and agile, and the overall experience is quite good.
Before the AION LX Plus, Brother Rumble did not know how long it had not been shocked by the so-called automotive technology, and the sponge silicon anode chip battery technology, the dual motor "four-in-one" integrated electric drive, the three-lidar system, the third generation of Qualcomm Snapdragon digital cockpit... One after another industry-leading black technology was launched, which made people feel the clear development path of GAC Aean with its scientific and technological foothold and steady development. As for how the AION LX Plus actually performed? Please continue to pay attention to the follow-up test drive experience of Brother Reed.
