Document Type and Number:
WIPO Patent Application WO/2022/134629
Kind Code:
A1
Abstract:
Provided in the present application is a battery pack master-slave dynamic parallel operation method, said method comprising during a discharging process, first performing discharging on a battery pack having a highest amount of power, and when a voltage difference value between various battery packs reaches a preset threshold range and a fault protection state has not been triggered, incorporating a battery pack having a lowest amount of power in performing discharging, and executing parallel operation mode switching; and during a charging process, first performing charging on a battery pack having a lowest voltage, and when voltages of various battery packs are uniform and a fault protection state has not been triggered, incorporating another battery pack in performing charging and executing parallel operation mode switching. Further provided in the present application are a powered device and a storage medium. The present application can satisfy large load power output and capacity expansion requirements.
