Kind Code:
A1
Abstract:
A system for managing a battery cell state, according to one embodiment disclosed in the present document, comprises: an information acquisition unit that acquires information about an injection amount of an electrolyte in a battery cell; and a controller that calculates a remaining amount of the electrolyte of the battery cell on the basis of a discharge amount of the electrolyte and the injection amount of the electrolyte according to at least one of manufacturing processes of the battery cell. The battery cell state management system, according to the embodiment, may collect data necessary for calculating the remaining amount of the electrolyte by means of being linked with a battery cell assembly system that performs the manufacturing processes, and accurately calculate the remaining amount of the electrolyte remaining inside the battery cell after the processes have been completed on the basis of the collected data.
