According to reports, through the world’s first large-scale battery cooling technology, Kirin batteries 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.
The 4680 battery is Tesla’s third-generation cell product. The cell product is cylindrical. “46” means the cylinder diameter is 46mm, and “80” means the cylinder height is 80mm.
It is worth mentioning that in extreme cases,Kirin battery cells can rapidly cool down and effectively block abnormal heat conduction between cells.And effectively avoid the irreversible damage caused by the abnormal working temperature of the battery, and improve the life and safety of the battery as a whole.
At the same time, 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 for free expansion and contraction, and improves the whole life cycle of the battery cell. reliability.
Not only that, the 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.
