Abstract: The present invention provides a battery quality detection method, comprising the following steps: selecting a plurality of test data with a data concentration greater than a first threshold; determining an upper limit curve and a lower limit curve for the selected test data; setting a standard detection range between the upper limit curve and the lower limit curve; obtaining a battery characteristic waveform of a battery; and comparing the battery characteristic waveform with the standard detection range to evaluate the battery's quality.

Abstract: Herein disclosed is a fire extinguishing system and a fire extinguishing method for electronic components. The fire extinguishing system comprises a fire extinguishing device, a control device, and a crane device. The fire extinguishing device comprises a camera module and a frame. The camera module captures a scene image related to a storage location in a machine. The frame has a fire tank for receiving an electronic component in the storage location. The control device receives the scene image and selectively sends a fetch instruction according to a status of the storage location. The crane device fetches the electronic component from the storage location to the fire tank according to the fetch instruction. Wherein the frame is fireproof.
