What is Qilin Battery?
Qilin Battery June 23, 2022 It is the third generation CTP technology of "Limit Breaking Qilin Battery" owned by CATL.
Qilin battery will get mass production in 2023.
Qilin battery has special features which are?
Structural improvement is the highlight of the Qilin battery.
Qilin Battery combines side members, water cooling panels, and thermal insulation panels into a multi-functional rubber interliner that combines utility requirements.
The built-in micron level bridge device in the sandwich can accommodate the battery core breathing flexibly, expand freely, and improve the reliability of the battery core throughout its life cycle.
The integrated power battery made of battery cells and multi-functional rubber interlayer creates a more stable power absorption structure in the direction of the vehicle and improves the battery's ability to withstand vibration and shock.
At the same time, it meets the national standards for battery safety tests such as beating.
Here are the 5 functions:
1. Strong heat resistance and safe.
The Qilin CTP3.0 battery adds a water-cooled foil between the two cells, which reduces the heat exchange between two adjacent cells, quadruples the heat exchange area and prevents heat dissipation; The temperature control time of the cells is short, it is reduced by half from the beginning, it supports 5 minutes of quick start and 10 minutes of quick charging.
2. The volume utilization rate is up to 72%, and the total range of the vehicle is 1,000 kilometers.
According to CATL announcement, Qilin battery is currently the world's highest built-in mobile power supply with a volume utilization rate of 72%, while CATL's first generation CTP technology has a volume utilization rate of 55%.
In the year In 2019, the range of new energy vehicles will be over 1,000 kilometers.
3. The specific power increases to 255 Wh / kg
Qilin battery creatively selects multiple functional modules to share the floor space, intelligently organize structural protection, high-voltage connection and heat dissipation functional modules, and increase the power space by 6% more.
And since the Qilin battery is essentially a process upgrade, the active material of the power battery remains unchanged, making lithium iron phosphate and ternary materials compatible.
When applied to lithium iron phosphate batteries, the weight energy density increases to 160 Wh/kg and the volume energy density exceeds 290 Wh/L.
4. Long battery life
Refer to the water-cooled plate that stores the timer to protect the internal chemical properties of the battery;
5. High voltage fast charging
Qilin batteries can meet high-voltage fast charging, and 4C charging is not difficult and will appear on the market next year.
What is the development history of Qilin battery?
In 2019, CATL launched the first module-less battery CTP to increase battery capacity by more than 50%. Now, with the overall improvement of the basic process, basic algorithm and basic material, CATL defines the battery structure design as Qilin.
On March 26, 2022, CATL chief scientist Cai Wu said at the China Electric Vehicle Forum 100 that the company had released CTP 3.0, known internally as Qilin Battery. The Kiln battery can increase performance by 13% compared to the 4680 system.
In May 2022, CATL chairman Zheng Yukun said in the online earnings conference that the Killian battery is expected to be officially launched in the second quarter of 2022. A battery with the same electrochemical system.
On June 23, 2022, CATL held a press conference on “Qilien Battery, Pushing the Limits” for third-generation CTP technology.
On June 23, 2022, CATL, one of the leading battery manufacturers, announced the third generation PTC (Integration of Direct-to-Battery Cell Technology) - the world's highest Kiln battery system integration with a utilization rate of 72%. And energy density 255 Wh/kg, pure electric vehicles for a full 1000 km.
summary
CATL's latest CTP3.0 Qilin battery not only reduces the structural components of the power supply, optimizes the internal space, reduces the weight of the battery pack and increases the size of the previous two generations of power battery, but has the overall performance of security.
As technology advances, people's mobility devices are becoming more convenient, safer and more practical. We expect the Qilin CTP3.0 battery to help make new electric vehicles safer and more convenient.
