Qualified Lithium Battery Pack

How many inspection processes does a qualified lithium battery pack go through?  

From raw materials to final product, a qualified lithium battery pack undergoes 56 production steps and over a thousand inspections. Leaving the production line is just the first step—each individual cell must pass thousands of in-line tests and more than 200 offline inspections. The CT scanning process for a single cell takes approximately 120 minutes, capturing 200 tomographic images to precisely detect micron-level defects.  

Inspection spans the entire manufacturing chain: incoming material inspection, electrode processing, cell assembly, formation and capacity testing, and PACK assembly. During incoming inspection, metallic impurities and moisture levels in cathode/anode materials, separators, and electrolytes are checked. In electrode processing, coating thickness, cutting precision, and surface defects are strictly controlled. After cell assembly, performance checks include OCV (open-circuit voltage), ACR (AC internal resistance), and housing voltage. Formation and capacity testing activates cells via initial charging and sorts them by capacity. Following PACK assembly, additional tests include charge/discharge cycles, overcharge/overdischarge tests, internal resistance measurement, capacity verification, short-circuit testing, and overcurrent protection.
