This application relates to a battery pack management system, a battery pack, a vehicle, and a management method. A method for dynamically managing parallel connection of a plurality of battery packs is provided, applied to a first battery pack, where the method includes: monitoring, by a BMS, states of the first battery pack and other battery packs, the states of the first battery pack and the other battery packs including a disconnected state and a connected state; and when determining that a difference between a power level of the first battery pack and a power level of another power pack in the connected state is in a preset threshold range, controlling, by the BMS based on the determination, the first battery pack to switch from the disconnected state to the connected state, the first battery pack being connected in parallel with the another battery pack; where the connected state includes a charge state and a discharge state, and the first battery pack is charged in the charge state and discharged in the discharge state.
