Abstract
The embodiment of the present application discloses a battery equalization control method and a control device. The battery equalization control method comprises: obtaining the charging and discharging state of a single battery. If the single battery is in a charging state, adding a charging equalization mark to the single battery meeting the condition of adding the charging equalization mark. If the single battery is in a discharging state, adding a discharging equalization mark to the single battery meeting the condition of adding the discharging equalization mark. Determining the charging and discharging equalization type and the charging and discharging equalization time, and performing discharging equalization. The embodiment of the present application distinguishes the charging and discharging state of the battery, respectively judges whether each single battery needs to be equalized, and determines the equalization time according to the charging and discharging state of the battery. The equalization discharging depth of each single battery needing equalization can be more accurately calculated, so that the consistency between the single batteries after equalization is higher, and the equalization effect is better.
