In the blink of an eye, the time has come to 2022. Just a few days ago, Mercedes-Benz released a new pure electric concept car, its wind resistance coefficient is as low as 0.17C, and the pure electric mileage exceeds 1000km. It can be said that 1000km is the ceiling of endurance for the current pure electric vehicle. And when everyone is still discussing when the concept car of Mercedes-Benz can be mass-produced, another "Made in China" pure electric vehicle will quietly be launched tonight, and its pure electric endurance is also more than 1000km, which is GAC Aion LX PLUS.
As a facelift of the AION LX, the AION LX PLUS is changed from the inside out. Among them, the improvement of pure electric endurance and acceleration capacity is more obvious. The AION LX has a maximum endurance of 650 km, while the AION LX PLUS will exceed 1000 km; the AION LX has a maximum zero-hundred acceleration time of 3.9 seconds, and the AION LX PLUS is shortened to 2.9 seconds. As far as these two data can be seen, the improvement of AION LX PLUS is not a half-hearted, take the endurance, AION LX PLUS will be the world's first pure electric endurance of more than 1000km mass production car.
The improvement of battery life is inseparable from the breakthrough of battery technology
For consumers, pure electric endurance of more than 1000km, I believe it can greatly reduce battery life anxiety. For a pure tram, more than 1000km endurance, which means that the battery pack must be "strong". And in this regard, it is a highlight of the AION LX PLUS.
AION LX PLUS uses a lithium-ion battery with a sponge silicon anode piece, with a battery energy density of 205Wh/kg and a battery capacity of 144.4kWh. Simply put, "silicon" is the key point of technological breakthrough. As we all know, most of the mainstream lithium batteries use graphite to make anode materials. Compared with graphite, silicon can store up to 9 times the lithium ions, which means that the use of silicon as an anode material can greatly increase the energy density of lithium batteries.
Therefore, the energy density of the battery pack of the AION LX PLUS can be as high as 205Wh/kg. However, there are two sides to everything, when silicon is used as a negative electrode material, after repeated charging and discharging, its material structure will become loose, so it will lead to a decrease in battery capacity.
Therefore, if you choose silicon as a negative electrode material, you need to cooperate with other technologies to suppress the attenuation of battery capacity, so the manufacturer also uses nano-composite silicon technology, adhesive technology with self-healing function and gradient composite coating technology.
With the blessing of this series of new technologies, the cell capacity of the new battery has been increased by 25%, the cell volume has been reduced by 20%, and the weight has been reduced by 14%. The reduction in volume and weight has a positive impact on the acceleration, braking, handling and spatial performance of the vehicle. According to official data, cltc has a comprehensive operating range of 1008km.
In less than 3 seconds to break the hundred, the two-stop dual motor four-in-one electric drive is the key
Earlier we also mentioned the acceleration capability of the AION LX PLUS, which accelerates in less than 3 seconds at zero hundred. Behind the strong acceleration capability is the upgrade of the drive system. AION LX PLUS (four-wheel drive version) is equipped with a new two-speed dual-motor four-in-one integrated electric drive assembly (four-in-one refers to the motor, electronic control, reducer and transmission four parts integrated into one), peak power 340kW, after deceleration and torque increased wheel end torque of up to 6100N·m, the comprehensive drive efficiency of more than 90%.
It is worth mentioning that AION LX PLUS (four-wheel drive version) is a front axle single motor, rear axle dual motor form, its three motors are permanent magnet synchronous motors, and compared to asynchronous motors, the advantage is higher energy efficiency, smaller motor size.
Ah Chuan commented on the car
For a car, the AION LX PLUS is just a facelift, but for the entire pure tram field, it is a breakthrough. The breakthrough of pure electric endurance, or the breakthrough of three-electric system technology. Previously, many people said that pure electric vehicles are the best "carrier" for domestic car companies to achieve curve overtaking. In the present view, this is indeed the case.
Take the core three-electric technology of pure electric vehicles, whether it is pure electric mileage or zero hundred acceleration time, domestic pure electric vehicles are in front of opponents. It is believed that with the listing of AION LX PLUS, in the following days, there will be more pure electric vehicles with a range of more than 1000km launched on the market. In time, will pure electric vehicles still make people anxious?
