Abstract
A battery management system (BMS) and a method of controlling the same are disclosed. In one embodiment, the BMS includes a reference setup unit configured to set a charge completion value used to calculate a state of health (SOH) of the battery, wherein the battery comprises one or more battery packs each including a plurality of battery cells, and a charge amount calculation unit configured to calculate an amount actually charged in the battery from a first point in time when charging of the battery begins to a second point in time when the battery charging actually reaches the charge completion value. The BMS may further include an SOH calculation unit configured to calculate the SOH of the battery based on a ratio of i) the actual charge amount to ii) a preset charge amount expected to be charged from the first time point to the second time point.
