Title:
POWER BATTERY GRADIENT UTILIZATION SCREENING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/055548
Kind Code:
A1
Abstract:
A power battery gradient utilization screening method and apparatus, and a device and a storage medium. The method comprises: acquiring in real time an infrared image in a charging process of a battery pack that is collected by a long-wave infrared instrument, wherein the battery pack is a retired battery pack (step 101); performing gridding processing on infrared images at a plurality of different moments to obtain a gridded infrared image corresponding to the infrared image at each moment, and determining a root-mean-square temperature of each grid in the gridded infrared image at each moment to obtain root-mean-square temperatures of each grid at the plurality of different moments (step 102); and acquiring an average temperature of the infrared image at each moment, and according to the root-mean-square temperatures of each grid at the plurality of different moments and an average temperature of the infrared image to which each grid belongs, determining whether a battery cell corresponding to each grid meets standards, wherein the battery cell that meets standards is used for gradient utilization (step 103).
