The disclosure discloses a battery balancing system, a vehicle, a battery balancing method and a storage medium. The battery equalization system includes: a collection module, used to collect parameter information of the single cells in the battery pack; a balance module, used to perform equalization processing on the single cells that need to be balanced through the storage battery, and the storage battery and the battery pack The single battery in the battery is connected; the control module is used to control the equalization module to pass through the monomer that needs to be balanced when it is determined according to the parameter information of the battery pack that there is a single battery in the battery pack that needs to be balanced. A battery discharges the battery. The disclosure solves the technical problem of wasting electric energy in the battery balancing system that adopts a passive balancing method in the related art by controlling the balancing module to discharge the single cells that need to be balanced to the storage battery.
Description
technical field [0001] The present disclosure relates to the field of battery pack balancing, and in particular, to a battery balancing system, a vehicle, a battery balancing method, and a storage medium. Background technique [0002] In electric vehicles, the power battery pack is an important part of it. Since the battery pack is composed of multiple single cells connected in series, as the battery is used, the differences between the individual cells in the battery pack gradually increase, resulting in poor consistency among the battery cells. Due to the short plate effect of the battery, the capacity of the battery pack cannot be fully utilized, resulting in a decrease in the overall capacity of the battery pack. Therefore, effective balanced management of electric vehicle power battery packs is conducive to improving the consistency of each single battery in the power battery pack, reducing battery capacity loss, prolonging the service life of batteries and the mileage...
