Title:
BATTERY INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/136353
Kind Code:
A1
Abstract:
In the present invention, for example, a single cell of a lithium ion secondary battery is an inspection target; in a first step, an inspection is performed regarding whether or not an internal short-circuiting is occurring in the single cell that is the inspection target; and in a second step, when an initial charge/discharge inspection (aging) of the inspection target is performed, the inspection target is charged until the SOC of the inspection target reaches 20-80%, and then aging is performed. Thus, achieved is a battery inspection method capable of significantly reducing the time required for the initial charge/discharge inspection without addition of an extra constituent material to the battery.
