The present technology relates to an apparatus for measuring a capacity of a battery cell, and a method of measuring a capacity of a battery cell. The apparatus includes: a jig configured to have a battery cell mounted thereon and press the battery cell from both surfaces; a charge/discharge unit configured to be connected to the battery cell; and a charge/discharge chamber configured to accommodate the jig and the battery cell, wherein a thermoelectric element for adjusting a temperature of the battery cell is formed on an external surface of the jig.

Apparatus and method for measuring capacity of battery cell

Disclosed are a method and a device for predicting a state-of-health of a battery and a battery management system using same. The method for predicting a state-of-health of a battery includes estimating state-of-health (SOH) estimation values for predicting an aged degree of the battery for each time; aligning the plurality of estimated values to create a history table; extracting candidate values from the history table; and determining a targeted SOH of the battery based on the candidate values.
