【Introduction: As GAC AION's "AION" series of models has promoted a package of "Plus", AION LX has also joined the "Plus" ranks, and the new car marks that the AION family has fully entered the new product 2.0 era of Plus. However, the most interesting point of this new pure electric SUV model is that the maximum cruising range is more than 1000 km and reaches 1008 km (CLTC conditions). 】

The AION LX PLUS model has launched four models with a price range of 286,660-459,600 yuan. As a modified model, the new car adopts the latest family design, this new car that integrates the latest technology of GAC Aean has caused an uproar in the industry, with a CLITC working range of 1008km, will this car be in the "inner coil" serious pure electric vehicle market, will it be able to kill a new world?
Sponge silicon anode battery technology support, the official endurance of more than 1000km
As we all know, most of the mainstream lithium batteries use graphite to make anode materials, but AION LX PLUS uses silicon to make anode materials; the silicon material can store 9 times more lithium ions than graphite, thereby improving the energy density of lithium batteries. However, silicon as a negative electrode material also has certain drawbacks, after repeated charging and discharging, the material structure will become loose, while the SEI solid electrolyte film will become thicker, resulting in a decrease in battery capacity. Therefore, if AION LX PLUS wants to get more power reserves, it must overcome the physical properties of silicon and delay its attenuation problem.
In this regard, after 5 years of research and development, GAC Aeon finally developed sponge silicon anode battery technology. This technology can control the volume of silicon materials in the nanometer range, and at the same time, with self-developed binders, the pole pieces have excellent coating, bonding and rebound properties. To put it simply, sponge silicon anode battery technology can make the silicon anode as soft and elastic as a sponge, so that the expansion and contraction of silicon in the process of charge and discharge is limited and buffered, and will not break, thereby reducing the attenuation problem of the battery pack. At the same time, in order to reduce the weight of the vehicle battery pack, GAC Aeon adopts a highly integrated package design, which increases the cell capacity by 25%, the cell volume by 20%, and the weight by 14%, which of course helps to improve the vehicle's mileage.
Can the actual endurance reach 1000km?
Although the Aion AION LX PLUS is the only model currently on sale with an official maximum mileage performance of more than 1000km, it should be pointed out that the 1008km range performance is measured under the CLTC operating conditions. In other words, there will be a discount on the actual mileage of this new car. A few days ago, a car self-media conducted a mileage test on this new car, after the vehicle was fully charged, in the case of an external temperature of 12 ° C, the air conditioner turned on the whole process of 24 ° C, the second wind block, from Hongqiao Airport to Jinhua, Zhejiang, maintaining a high-speed driving speed of 120km/h. After 5 hours and 16 minutes of continuous driving, the vehicle's power ran from 97% to 2%, and the final measured cruising range was 518km, the average speed was 99.86km/h, and the energy consumption shown was 24.8kWh/100km, which was different from the official advertised value.
However, the above measured mileage is carried out at high speed, which does have a greater impact on the performance of the vehicle mileage. According to another automotive self-media test, Guangzhou to Shantou, 20% of the city + 80% of the national road conditions, the temperature is 12 °C -16 °C, the measured endurance is 821 km; Beijing - Taishan, 30% of the city + 70% high speed, the day the temperature is -9 °C -4 °C, the measured endurance is 756 km and so on. It can be seen that under normal circumstances, the actual cruising range of the AION LX PLUS tested is between 700-850km, which is not up to the advertised 1008km. To put it bluntly, if you want to achieve a range performance of more than 1000km, you must ensure that the vehicle is tested under ideal operating conditions.
Although the endurance has increased, the convenience of replenishment cannot be ignored
There is a saying that even if the actual mileage is lower than the official announcement, the endurance of the AION LX PLUS has reached a high level. However, can the endurance of 1000km+ solve the anxiety of endurance? Not necessarily. When the electric car was just launched, the mileage was only 300km+, and today's mainstream mileage level has reached 600km+, but the problem of endurance anxiety has not been alleviated to a great extent.
You know, compared to the number of endurance, the convenience of replenishment is also important.
Due to the absence of the 800V voltage platform, the energy repair speed of AION LX PLUS is not fast, it can only be said that the efficiency is not bad, and the charging time of about half an hour can probably increase the cruising range of this car by about 300km. However, if you can't find a DC fast charging pile with 750V high voltage and above, then the energy replenishment time of AION LX PLUS is still a big problem.
It should be pointed out that during the Spring Festival holiday, there are many travel vehicles, and the service area on the highway is often overcrowded, if the AION LX PLUS owner needs to wait for several hours in the service area to be fully charged, then the so-called mileage anxiety relief has to be marked with a question mark.
Comments
The official announcement of the highest cruising range of more than 1,000km AION LX PLUS in the pure electric vehicle industry, is a big breakthrough, but at the same time, the actual mileage of this car in the actual measurement process is still not up to 1000km. For AION LX PLUS, in order to solve people's range anxiety, in addition to increasing the mileage performance of the vehicle, it is also important to improve the convenience of charging.
