Inventors include Hong, Junhyeon; Choi, Hodeuk; and Jeon, Younghwan Pctkr No.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: This cell balancing method for a battery pack comprising a plurality of battery cells comprises the steps of: determining a balancing target cell requiring cell balancing among the plurality of battery cells; measuring a first voltage for the balancing target cell and measuring a first pack current flowing through the battery pack; turning on a balancing switch connected to the balancing target cell; measuring a second voltage for the balancing target cell and measuring a second pack current flowing through the battery pack; determining a balancing current calculation method according to the difference between the first pack current and the second pack current; if the difference between the first pack current and the second pack current is within a predetermined range, calculating a balancing current by using the first voltage and the second voltage; if the difference between the first pack current and the second pack current is outside of the predetermined range, calculating the balancing current by using the first voltage, the second voltage, and a voltage change amount resulting from an internal resistance of the balancing target cell; and estimating a state of charge (SOC) of the balancing target cell according to the balancing current.
