Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method for early warning and diagnosis of a lithium-ion power battery. Background technique [0002] Lithium batteries have the characteristics of small size, light weight, environmental protection, high energy density, no memory effect, and long cycle life. With the in-depth development of the digital society, its application tends to be extensive, ranging from small devices such as notebooks, mobile phones, and handheld GPS to large vehicles such as electric bicycles and even electric vehicles. In practical applications, lithium batteries sometimes experience overcurrent, overvoltage, overtemperature, etc., resulting in performance degradation and a greatly shortened service life; in severe cases, accidents such as violent explosions may occur, endangering personal safety and causing property losses. Contents of the invention [0003] The technical problem to be solved b...
