Through the world's first large-scale cell cooling technology, Kirin batteries can support 5-minute fast hot start and 10-minute fast charge. Under the same chemical system and the same battery pack size, the power of the Kirin battery pack is 13% higher than that of the 4680 system, achieving a comprehensive improvement in battery life, fast charging, safety, life, efficiency, and low temperature performance. Kirin batteries will be mass-produced and launched in 2023.
It is understood that Kirin battery conducts a comprehensive simulation of the electrochemical reaction of the whole life cycle and the real vehicle requirements of the water cooling system, builds a micro-bridge connection device in the multi-functional elastic interlayer, flexibly cooperates with the respiration of the battery cell to freely expand and contract, and enhances the whole life of the battery cell. Cycle reliability.
At the same time, an integrated energy unit is composed of a battery core and a multi-functional elastic interlayer. Build a more stable force-bearing structure perpendicular to the driving direction to improve the structural strength and impact resistance of the battery pack.
Kirin Battery also pioneered the large-surface cooling technology for cells, which shortens the temperature control time of cells to half of the original. In extreme cases, Kirin battery cells can rapidly cool down, effectively blocking abnormal heat conduction between cells, and effectively avoid irreversible damage caused by abnormal operating temperatures of the battery, improving overall cell life and safety.
In fact, as early as the 8th China Electric Vehicle 100 Forum held on March 26 this year, CATL officially announced that it would launch CTP3.0 batteries, which became the focus of the industry.
Wu Kai, chief scientist of CATL, said at the 2022 World Power Battery Conference that the Kirin battery has the following characteristics: First, the CTP3.0 battery adds a water-cooling sheet between the two cells to make the two adjacent cells Second, because the water-cooled sheet has a buffering effect, the battery life is greatly improved; third, the Kirin battery can meet high-voltage fast charging, and 4C charging is not difficult; fourth, the Kirin battery can improve the internal Space utilization, the energy density of the lithium iron phosphate system is 160Wh/kg, and the ternary high nickel can reach 250Wh/kg, which is 13% more power than the 4680 battery.
The 4680 battery is Tesla's third-generation battery product, which Tesla debuted at its Battery Day event in September 2020. According to reports, the battery is 80 mm high and 46 mm in diameter. Compared with traditional lithium batteries, the energy density is increased by 5 times, the cruising range is increased by 16%, and the cost is reduced by 14%.
It is understood that CTP (abbreviation of English Cell to Pack, namely no module power battery pack) technology is to integrate the cells of the battery into the battery pack, reducing the gap between the modules and bringing the volume utilization rate of the car. Improvement, the energy density of the battery pack is greatly enhanced, the number of vehicle parts is reduced, and the production efficiency is improved.
In September 2019, CATL and BAIC New Energy jointly launched the world's first CTP battery pack, which was installed on BAIC New Energy's popular model EU5 for the first time. Due to the cancellation of components such as the module side plate and a number of processes, the overall utilization rate of the battery pack will be increased by 15%-20%, and the production efficiency will be increased by 50%.
The second-generation CTP technology of CATL optimizes the two end plates of the module and integrates the cells directly into the battery box.
After the CATL era, many companies have successively launched their own CTP products:
In 2000, BYD launched the blade battery (GCTP), which adopts a module-free design, and the internal cables and structures are greatly reduced, which ultimately increases the battery volume utilization rate by more than 50%, reduces the number of parts by 40%, and reduces costs. 30%.
Honeycomb Energy's CTP technology includes two types: no-module solution and large-module solution. Compared with the traditional 590 module, the first-generation CTP battery pack will reduce the number of parts by 24%; the second-generation CTP will increase the weight group efficiency by 5%-10%, increase the space utilization rate by 5%, and further reduce the battery by 22%. number of parts.
Gateway Power, based on the concept of large soft pack modules, launched LCM & building block batteries. The idea is to improve the space utilization rate through changes in the thickness, length, and width of different batteries, so that the cells are arranged in the form of building blocks in the battery pack. Under the condition of a certain cell width, the volume utilization rate of the building block battery is increased by 8%-12%, and the cost is reduced by 10%-15%. At present, Gateway's power building block battery technology has matured, and samples are sent to international car companies, and the domestic scale promotion and application is imminent.
The battery capacity of the Envision Power Soft Pack CTP will be doubled in the same space, and the battery life will be extended to 1000km. It is expected to be mass-produced in 2024...
Next, the goal of CATL is to mass-produce batteries that meet the requirements of no thermal diffusion and have a cruising range of 1,000km in 2023, and is expected to mass-produce a battery-chassis combination using CTC technology in 2025. Two important components are integrated into one.
