Description

technical field [0001] The invention relates to a battery screening system and method, in particular to a screening system and method for low-voltage battery detection. Background technique [0002] With the continuous improvement of people's cultural and living standards, the core technology of related electronic products is changing with each passing day. Batteries have become an indispensable must-have for modern people, which enables people to use various portable electronic devices in their lives and work. [0003] At present, in the production process of lithium-ion batteries, battery screening is usually required after the pre-charging of lithium batteries is completed and before they are converted into capacity, and batteries with a voltage lower than a certain value are screened out for downgrading. [0004] However, the existing method of screening low-voltage batteries before the composition and capacity is usually to use a multimeter to manually read the voltage ...
