CHARGING METHOD, CHARGING DEVICE, AND BATTERY PACK

摘要

A charging method is a method for charging assembled cells formed by connecting two or more cells in series. Specifically, constant-current charging is performed on the assembled cells, and when the inter-terminal voltage value of one of the cells reaches a first voltage value, the charging current value is reduced from the first current value to a second current value, and constant-current charging in which the charging current value is the second current value is performed on the assembled cells.
