If the endurance of pure electric vehicles reaches 1000km, the consumer market may change greatly, of course, this refers to the situation that can be generally achieved. At this stage, there are also some models that have achieved a surface endurance of 1000km, but the burden on the battery is also quite large, in the future of the price of power battery raw materials, perhaps this practice is still not a good choice, let's take a look at it together.
GAC AION LX Plus
Listing time: January 5, 2022
Official guidance price: 286,600-459,600 yuan
As the flagship model of the GAC BJEV family, the LX's initial highlight is its supercar acceleration capability, and today's Plus version is the world's first pure electric model to break through the range of 1000km, and the CTLC has a cruising range of 1008km. Of course, some netizens said that CTLC was even weaker than his kidney, but it is undeniable that AION LX Plus did it.
The design of AION LX Plus has been upgraded to a certain extent, but the overall use of AION family style, the car is equipped with a 15.6-inch large screen, equipped with ADIG4.0 intelligent IoT system, including AR real-world navigation, sensorless start and other advanced functions. The premium version will feature 35 high-performance perception hardware, including three second-generation lidars for advanced driver assistance.
The battery pack that achieves a battery life of more than 1,000 has an energy density of more than 205Wh/kg and a large battery power of 144.4kWh. The power part is available in two versions: single motor 180kW/350N·m and dual motor 360kW/700N·m. The overall endurance is available in 600km, 650km and 1008km versions.
NIO ET7
Delivery time: Q1 2022
Official guidance price: 448,000-526,000 yuan
This is a medium-sized and large sedan of Weilai, although it has not yet been delivered, but it has been the first to be listed to accept reservations, which is also the consistent practice of the new forces. In terms of endurance, in order to achieve a breakthrough of 1000km, the user still chose a large battery pack, and the user can choose to install a 150kWh solid-state battery, but the price is higher than the top 526,000.
Compared with other models of Weilai, the ET7 is more sporty, the front face still adopts the family design language, and the split scenery has a high degree of recognition. The interior is also familiar with the NIO layout, and equipped with lidar, up to 33 sensors, will allow the ET7 to achieve a stronger automatic driving assist function than the current NIO model.
In terms of cruising, there are three versions to choose from, with a cruising range of more than 500km, 700km and 1000km respectively. The power part is consistently high-performance, equipped with dual-drive motors in front and rear, and achieves eye-catching data of 480kW/850N·m.
Zhiji L7
Delivery time: April 2022
Pre-sale price: 408,800 yuan (Angel Wheel Edition)
Zhiji L7 is also known as the endurance can exceed 1000km, is currently in a state of imminent delivery, 115kWh battery capacity is relatively small, but it is only a follow-up version. At this stage, the angel wheel version has a cruising range of 615km.
As a coupe model, the Zhiji L7 is quite slender and smooth, and the excellent performance of wind resistance is also the key to helping it break through the 1000km endurance. The interior adopts a zero-button design, and the oversized integrated screen reaches 39 inches, and the tea brother said that the TV set at home is only 40 inches.
In the power part, zhiji L7 will adopt a drive system with dual motors in front and rear, with an overall performance of 400kW/700N·m parameters, and is also a pure electric new car with the main performance.
Power battery upgrade
It can be seen that in order to achieve a large increase in battery life, it is basically necessary to rely on the capacity increase of the battery, which means that the weight and cost are rising, which is not conducive to the development of long-lasting trams, and the upgrade of the power battery is imminent.
According to the news on February 15, Japan's Edico Company has developed a new generation of lithium-sulfur battery prototypes, and the energy density can reach twice that of existing lithium batteries, which means that the endurance can be doubled.
At present, the company has cooperated with relevant battery manufacturers to achieve the commercialization of electrode material sales in 2030, and the large-scale commercial use of lithium-sulfur batteries is already on the way. In fact, engineers from Drexel University in the United States have made significant progress in the research and development of lithium-sulfur batteries, and the capacity can reach three times that of general lithium batteries, but it is more difficult to commercialize.
The battery developed in Japan is also a lithium-sulfur battery, and the new material is called sulfide polyacrylonitrile SPAN, and the sulfur concentration has reached 48%, which is 10% higher than in the past. As long as the sulfur-containing electrode material is increased, the power storage will increase, but at the same time, the durability will be greatly reduced. Therefore, it is regrettable that the current prototype can only be recycled dozens of times, and it is also necessary to optimize and upgrade the negative electrode material to improve, but it is undoubtedly a direction worth trying.
At present, the price of ternary lithium batteries and lithium iron phosphate batteries relied on by new energy models is rising, but the endurance has reached its peak. It is difficult to improve again. The mainland's lithium storage is not rich and needs to rely on imports, so for long-term development, the exploration of power batteries is still the key to future development.
