6 month 23 Daily news , Today, , Ningde times officially released CTP3.0 Kirin battery , The system integration has reached a new high in the world , The volume utilization ratio is broken 72%, The energy density can reach 255Wh/kg, The whole vehicle can be realized 1000 Km range , Will be in 2023 It's on the market in mass production .
According to introducing , Through the world's first large area cooling technology for power cells , Kylin battery support 5 Minute quick hot start and 10 Minute quick charge . In the same chemical system 、 Under the same battery pack size , The power of the Kirin battery pack , comparison 4680 System improvement 13%.
4680 Battery is Tesla's third-generation cell product , The electric core product is cylindrical ,“46” Represents a cylinder with a diameter of 46mm、“80” It represents that the height of the cylinder is 80mm.
It is worth mentioning that , In extreme cases , Kirin battery cell can rapidly cool down and effectively block abnormal heat conduction between cells , And effectively avoid irreversible damage caused by abnormal operating temperature of the battery , Improve the service life and safety of the battery as a whole .
meanwhile , Kirin battery aims at the full life cycle electrochemical reaction 、 The water cooling system shall be fully simulated according to the actual vehicle requirements , A micro bridge connecting device is built in the multifunctional elastic interlayer , It can flexibly cooperate with the breathing of the electric cell for free expansion and contraction , Improve the whole life cycle reliability of the cell .
More Than This , The integrated energy unit is composed of an electric core and a multifunctional elastic interlayer . Build a more stable stress structure perpendicular to the driving direction , Improve the structural strength and impact resistance of the battery pack .
