  "textContent": "The present application discloses a method, apparatus, device and medium for equalization control of battery packs. The method may include: acquiring a voltage of each of a plurality of cells of the battery pack; on the condition that one or more voltages of the voltages of the plurality of cells are within a preset voltage interval, selecting a target State of Charge (SOC)-Open Circuit Voltage (OCV) curve from a charging SOC-OCV curve and a discharging SOC-OCV curve stored for the battery pack based on the voltages within the preset voltage interval; acquiring a target SOC of each cell based on the target SOC-OCV curve and the voltage of each cell; calculating, for each cell, a SOC difference between the target SOC of the cell and a reference SOC; calculating an equalizing time for each cell based on the SOC difference of each cell; the preset voltage interval is determined based on a hysteresis interval. According to embodiments of the present application, the equalizing information can be precisely obtained for cells with a hysteresis effect.",
