The invention discloses a battery equalization system, a vehicle, a battery equalization method and a storage medium. The battery equalization system comprises a collecting module, an equalization module and a control module, wherein the collecting module is used for collecting parameter information of battery cells in a battery pack; the equalization module is used for charging the battery cellsneeding to be equalized through a power supply unit, wherein the power supply unit is a storage battery or a power generator; and the control module is used for controlling the equalization module tocharge the battery cells needing to be equalized through the power generator or the storage battery when it is determined that the battery cells in the battery pack need to be equalized according to the parameter information of the battery pack. According to the battery equalization system, the battery cells needing to be equalized can be charged through the power generator or the storage battery,and the technical problem that in related technologies, electric energy is wasted when the battery equalization system adopting a passive equalization mode conducts equalization is solved.
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 battery pack is an important part. 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 battery packs is conducive to improving the consistency of each single battery in the battery pack, reducing battery capacity loss, prolonging the service life of batteries and the mileage of electric vehicles, w...
