Title:
QUALITY MANAGEMENT METHOD FOR ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/110328
Kind Code:
A1
Abstract:
A gas component is acquired from an electricity storage device that is to be managed and is normal. Next, an electricity storage device E to be managed is acquired from a customer S, gas is generated by applying a thermal load or an electric load to the electricity storage device E as needed, and a generated gas (management gas) component is analyzed. After the gas component generated from the electricity storage device E to be managed is analyzed, the management gas component and a reference gas component are compared, and the normality or abnormality of quality of the electricity storage device E is determined according to whether the difference of the management gas component from the reference gas component is a slight difference or a significant difference. The result of determination of normality or abnormality of quality of the electricity storage device E is presented to the customer S. According to this quality management method for an electricity storage device, on the basis of a gas component generated from an electricity storage device used in electronic equipment, an automobile, or the like, the quality of the electricity storage device can be managed.
